How to start craftsman lawn mower?


Before you start your craftsman lawn mower, you should make sure you are fully prepared and familiar with the operating instructions. It is important to check the oil level and the fuel tank level, as well as the condition of the spark plug. Additionally, you should familiarize yourself with the safety features and be aware of all relevant safety and caution signs.

Once you have confirmed that everything is in good condition, you can start your mower.

Choose the right mower for your lawn size

Choosing the right lawn mower is an essential step when starting a craftsman lawn mower. Before you go shopping, it’s important to assess the size of your lawn and select a machine that’s best suited to it. A push mower is perfect for smaller yards of up to 1/4 acre, while homeowners with more space might opt for a ride-on mower. If you live in a small home but have an especially large yard, you might even consider investing in two separate machines to take care of different jobs on different areas of your lawn.

Another factor to consider when selecting the right mower is compatibility with the space you have available for storage. Large, ride-on models pale in comparison with smaller push mowers when it comes to spatial requirements, so if garage or shed size is an issue be aware that you may need additional storage space for your new machine. It’s also important to think about your budget and decide in advance what type of model and features are essential within that budget. This way, it will be easier for you to make informed decisions when comparing models from different brands and manufacturers at garden warehouses or online stores.

Read the operator’s manual

Before you begin operating a craftsman lawn mower, it is important to read and understand the operator’s manual. Be sure to review both the safety and operation tips so you know how to safely use the mower and keep it in good working order.

Be sure that all safety and assembly decals are in place on the machine before turning it on. Not only will they alert you of any potential hazards, but they may also indicate how the machine should be operated correctly. Familiarize yourself with all switches, buttons, levers and other controls before starting.

Be aware of your surroundings when using a lawn mower and make sure children or pets are a safe distance away from where you are working. This can help to prevent any injuries or accidents from occurring. Additionally, never leave fuel-powered tools unattended when they are running as this may result in fire or explosion.

Check the mower for any damage

Prior to starting the mower, it is important to check for any signs of damage or wear. Examine the tire treads and check that they are not worn or damaged in any way. Look along the edges of the mower where it meets the ground and make sure there are no sharp objects such as rocks, sticks, twigs, or other debris that could cause damage when being moved across a lawn. Check all fastening hardware, such as nuts and bolts, to ensure everything is tightened down properly.

Next, check the gas and oil levels. The manufacturer’s recommendations for fuel should be followed closely to ensure optimal performance and safety. An oil level indicator is found on most lawn mowers for easy checking; if this is present make sure it indicates proper oil levels before continuing with the starting procedure.

Inspecting air filters are an important step before starting any lawnmower powered by a gasoline engine. If the air filters become clogged due to dust or debris they will reduce engine performance and can lead to long-term damage if not inspected regularly. Check that all air passages are open so that airflow can move freely without obstruction during operation. Also make sure that hoses connections on a pull-start mower have been attached securely as loose parts can become detached during operation potentially injuring yourself or another person nearby.

Starting the Mower

Starting a Craftsman lawn mower is a relatively straightforward process. Before you start, make sure to check your oil and gas levels, as these can affect the performance of your mower. Once you’ve determined that you have the necessary fuel and oil, you can then begin the process of starting the mower. Read on to learn more about the steps involved in starting a Craftsman lawn mower.

  1. Check the oil and gas levels.
  2. Make sure the spark plug is connected.
  3. Set the choke lever to the “on” position.
  4. Turn the key to the “start” position.
  5. Pull the starter cord.
  6. Set the choke lever to the “off” position.
  7. Push the throttle lever to the “fast” position.

Check the oil level

Before you attempt to start your Craftsman Lawn Mower, it is important to check the oil level in the engine. This can be done by looking at the dipstick located on the side of the engine. If there is not enough oil, make sure to add enough 10W-30 or SAE 30 motor oil so that it reaches the “full” level marked on the dipstick. Too much oil can be damaging as well, so if there is already oil present make sure not to overfill it. It is important to use fresh oil and replace after every 25 hours of use to keep your mower running smoothly.

Once you have checked that enough oil is present for proper lubrication, you are now ready to begin starting your Craftsman Lawn Mower.

Prime the engine

Before starting your Craftsman lawn mower, the engine must be primed. Priming is the process of allowing fuel to travel to the carburetor for efficient combustion. Most Craftsman mowers have a primer button that you can press several times in order to get the air pressure needed to transfer fuel from the tank through a valve and into a small hose in the carburetor.

Once you have pressed the primer button several times, you should turn on your mower’s ignition switch. This will allow electricity to enter your mower’s electrical system and activate certain parts, including the spark plug. When this happens, it creates an electric charge that causes a spark and ignites the fuel in your engine at just the right time for it to burn properly.

You may hear a clicking sound when turning on your engine; this confirms that your spark plug is functioning correctly and allows air into your engine’s cylinder at exactly the right time for efficient combustion to take place. After several clicks, depending on how much residual pressure is left from priming, you are ready to start up your Craftsman lawn mower by pulling its starter cord.

Set the choke

Before attempting to start the engine, turn the gas valve to the “ON” position. Check to make sure your mower is on a level surface. If it’s not, there is a greater chance you’ll flood the motor and it will be difficult or impossible to start. Make sure the lawn mower battery is still good or if there’s one installed, has enough fuel in it. You can also use starter fluid in the lawn mower but read and follow the instructions of your particular lawn mower model when using starter fluid as it can be hazardous.

Once everything is in place, locate where your choke lever is located and move it into “Choke” position. Most Craftsman mowers are equipped with a filet blade mounted on the chassis that allows you to safely locate this lever as well as other levers associated with starting up your engine like throttle and primer bulb. This should help reduce any confusion and make starting your machine that much easier!

Pull the starter cord

Most Craftsman lawn mowers have a pull-starting system, which is operated by a cord that needs to be pulled multiple times in order to start the engine. Prior to starting the engine, check to make sure that both the choke lever and fuel valve are turned on (on most engines, both are located on the side of the machine).

Next, prime the mower’s engine three times. This helps get the fuel circulating through the system and up into the carburetor. Most models will have an easily identifiable priming hole near either end of the cylinder; press down firmly on this hole three times in order for it to take effect.

Once you’re ready to start, pull on the starter cord with one steady motion until you feel resistance in your arm – resist pulling any further at this point. Once you reach this point let go of starter cord slowly. When done correctly it should produce a ‘chugging’ sound once pulled – this is not necessary for successful starting but it does indicate that more gas is reaching your engine’s cylinders. After waiting for several seconds, repeat these steps again until your mower starts running smoothly –for many models’three pulls do typically suffice.

Make sure never to pull sharply otherwise this can strain your starter mechanism which can lead to costly repairs or replacements in some cases –pull slowly and steadily while also listening carefully for any grinding or slipping type noises which may indicate potential damage.


Taking proper care of your Craftsman lawn mower will ensure it works reliably and efficiently. Regular maintenance is important to maintain your mower and extend its life.

Here we will discuss the various maintenance tasks you should do to keep your yard looking great. From changing the oil to checking the belts, proper maintenance is key to a successful lawn mowing experience:

  • Change the oil.
  • Check the belts.
  • Clean the air filter.
  • Sharpen the blade.
  • Check the spark plug.
  • Check the fuel filter.
  • Check the tires.
  • Check the battery.

Change the oil regularly

Maintaining the oil of your Craftsman lawn mower is incredibly important in order to get the most out of your machine. It is recommended to change the oil regularly, typically every 25 hours of use or once a year depending on how often you use it. To start, park your Craftsman lawn mower on a level surface and ensure that it is completely cool before beginning.

Set aside the appropriate type and quantity of oil for your engine’s make and model. Check your manual, as different engines may require different types of oil such as synthetic, mineral or even semi-synthetic. Generally, 4-cycle engines use SAE 30 motor oil while 2-cycle engines use a combination of unleaded gasoline mixed with two stroke engine oil.

Once you have selected the right type and quantity of oil needed for your engine’s make and model, locate the dipstick to check levels. Start by unscrewing the cap located at the base of the dipstick then rest assured that there is enough oil for your engine before replacing it into its housing. Clean off any excess dirt or debris from around the area before continuing onto adding new oil into its chamber as well as ensuring that everything is airtight/ tight when finished with this step in particular. Finally, top off additional oil if needed and test crank/ engage starter after completing this process until you hear even engine running sounds or another set sign for successful practice completion followed by disposal in accordance with local regulations!

Clean the air filter

Proper maintenance of a Craftsman lawn mower is essential for peak performance. Caring for your mower involves steps such as regularly checking the oil and fuel levels, sharpening the blade, and cleaning the air filter. A dirty air filter reduces your mower’s performance, resulting in increased fuel consumption and reduced engine power. Therefore, on a regular basis, you should clean or replace the air filter on your mower according to the manufacturer’s instructions.

When replacing or cleaning an air filter:

  • Locate your engine’s air filter; it will be in a storage box near where the spark plug is located.
  • Carefully remove it from its housing and discard it if it has been used before as a new one must be used each time.
  • If you are cleaning the old one, make sure to tap out any excess dirt or dust that may be settled inside by lightly pounding or shaking it with your hands over a trash can to avoid making a mess.
  • Then use soap and water or compressed air to clean away any remaining debris from within its slots before drying completely with an absorbent cloth.
  • Finally, when done thoroughly drying off your now clean element, carefully replace it back into its housing while making sure that all seals are properly secured before taking off once again!

Sharpen the blades

Maintaining your lawn mower blades is key to ensure that your lawn looks its best. For the safest and most effective sharpening of your Craftsman lawn mower blades, use a rotary blade sharpener kit. Use these simple steps to keep your mower blade sharp and ready for use:

  1. Turn off the engine of the lawn mower and remove the key from the ignition switch. Disconnect the wire from spark plug.
  2. Thoroughly clean any dirt or grass clippings from the top side of both cutting blades before you start sharpening them.
  3. Set up a rotary blade sharpener according to manufacturer’s instructions, which should include affixing a cutting stone to a power drill, adjusting the guide arm height so it sits half an inch higher than any part of the blade you plan to sharpen, and pressing down gently on grinding stone while running at low speed with power drill chuck in contact with beveled edge of cutting blade.
  4. Move grinding stone lightly six times from tip to root over both edges of cutting blades, making sure that you do not overheat or oversharpen them – this will damage them beyond repair! Always put safety first; wear protective eye gear for added protection during this task!
  5. Once both edges have been honed to desired level of dullness (which should look shiny but not razor-sharp), it’s time to clean up after yourself before reassembling everything back together: wipe any excess metal shavings away from lawn mower body with cloth; throw them out in waste bin rather than leaving behind dirt patch! Replace spark plug wire and replace key in ignition switch before restarting engine and using again!

Check the spark plug

Before starting your Craftsman lawn mower, you must check the spark plug to ensure it is in good working condition. The spark plug supplies the power to fire the engine, and without this working properly, your lawn mower won’t start.

Begin by removing the spark plug using a ratchet wrench or a right angle spark plug socket. Once removed you should inspect it for any visible damage such as corrosion or debris that may cause faults with its operation.

If you notice any problems with the spark plug from your inspection, then you should replace it with one of the same type and characteristics as recommended in your lawn mower’s owner’s manual. You can locate an exact replacement from your local hardware store or online retailers. Once replaced, securely tighten up by hand first before tightening further with a small ratchet wrench until just before resistance is found – Do not overtighten!

If there were no issues located during inspection, reinstall the same spark plug securely back into position and reconnect its wire. This will be a red wire typically cable tied to the engine frame but may also be colored differently – refer back to your manual if unsure. Make sure everything is secure and no wires are exposed to prevent accidents around fuel or heat sources while running.


It is important to troubleshoot a Craftsman lawn mower prior to starting it. If it is not working correctly, it can cause damage to the engine or even stop working completely. This section will provide tips on how to properly troubleshoot a Craftsman lawn mower prior to starting it. These tips can help to ensure that your lawn mower is running smoothly and will save you time and money by avoiding unnecessary repairs.

Check the fuel line

When the fuel line is blocked, clogged or cracked, your Craftsman lawn mower will not start. To check the fuel line for any blockage or damage, pull out the spark plug. Disconnect the small plastic tube from both ends of the fuel tank and blow air through it using a bulb-type tire inflator. If you cannot blow air through it, then replace it with a new one; otherwise your mower will not start.

To ensure that enough fuel is reaching the spark plug, repeat this procedure and allow some fuel to escape into a rag before reconnecting everything back together. Make sure to replace the siphon filter if there is any obstruction in it and inspect all other lines for cracks and leaks before attempting to start your Craftsman lawn mower.

Inspect the spark plug

Before attempting to start your Craftsman mower, it is important to inspect the spark plug. If the spark plug is worn out and in need of replacement, the engine may not be able to output enough power for the starting procedure.

Before servicing and replacing this important component, make sure the engine is cool, the battery has a full charge and all safety precautions are followed. Once inspected, you can begin the testing process by removing from its wire from out of the spark plug so that no electrical current is supplied when running tests. Utilizing a spark plug tester or an ohmmeter will allow for appropriate examination of potential problems. This tool should indicate small levels of resistance when connected across both terminals which indicate strong ignition activity or lower levels that may signal a faulty or malfunctioning spark plug.

In addition, check with visual inspection for any signs of damage such as evidence of overheating or worn electrodes which can cause insufficient voltage and pressure to be sent through to ensure successful starting conditions. If any such problems arise with these components, care should be taken in replacing them thoroughly with manufacturer-approved replacements, before continuing with other troubleshooting procedures.

Check the carburetor

Carburetors are an important component of any lawn mower’s engine, and they require regular maintenance to work properly. In order to properly troubleshoot a Craftsman lawn mower that won’t start, you will need to check the carburetor and all related components.

  • Start by making sure the fuel tank is full and topped off with fresh, untreated gas. If the gas has been sitting for more than a few weeks it may need to be replaced. Then take off the air filter and spray a small amount of pressurized air into the housing from behind. This will help blow out any dust or debris that might have collected in the filter box.
  • Next, check the fuel lines for any obstructions or holes that may be preventing adequate fuel flow. Replace if needed, then make sure all fuel connectors are secure before reattaching them to their respective ports on the carburetor assembly.

Before starting your mower it is important to ensure that all parts are correctly aligned and in working order; this includes checking the tension of spark plug wires, cleaning out any debris near/around plug ports, or tuning/adjusting throttle levels as necessary. Lastly, run your finger along each blade; they should spin freely without feeling jerky or jolting – if not replace or sharpen blades accordingly before starting up again!

Clean the carburetor

The carburetor is responsible for controlling the amount of fuel that is mixed with the air and then delivered to the engine in order to generate power. If it is clogged, the engine will not run properly. For a Craftsman lawn mower, it is important to follow a few steps in order to correctly clean the carburetor and get your mower going again:

  1. Disconnect any wires or hoses hooked up to it.
  2. Remove the bowl screw located on top of the carburetor, making sure to keep track of where each part belongs.
  3. Use a cloth or brush to wipe away any debris from around the area and take out any dirt or grime that has built up on the inside of it.
  4. Put back each part in its corresponding place and reinstall any wires and hoses that you may have removed for access.
  5. Check for any fluid leaks around the bowl by running your finger along any exposed surfaces before restarting your mower as this could indicate improper assembly and/or deterioration of components inside the carburetor itself.
