How do I change the engine oil?

Ensure that you change the engine’s crankcase oil at least once in every 100 hours of use – remember to change the oil filter once in every 200 hours of use.

  1. Stop the engine after parking the mower on a level surface. Ensure that the engine oil is warm before you attempt to drain it. If the oil isn’t warm, start the engine and leave it running for a few minutes – this will help warm up the oil.
  2. Clean out the area surrounding the oil dipstick before you remove it.
  3. Drain the oil into an appropriate container – make sure that you give the apparatus enough time for all the oil to completely drain out.
  4. Remove dirt and debris by cleaning the area around the filter before you remove it.
  5. Take off the older filter and wipe the mounting surface off on the engine.
  6. Use fresh oil to apply a thin coat to the rubber gasket on the new filter.
  7. Install the new filter by turning it clockwise – keep turning until the rubber gasket comes into contact with the surface of the sealant. Tighten it slightly more by an additional turn.
  8. Close and tighten the oil drain valve firmly but take care not to tighten it too much.
  9. Now fill the engine’s crankcase with the new clean oil – ensure that the lubricant being used is one that has been recommended by the engine manufacturer.
  10. Check for oil leaks after starting up the engine. Inspect the oil level once again and add more oil if required

How do I change the deck gearbox oil?

Ensure that you check the gearbox oil seals at least once after every 25 hours of operation for any possible leaks. If you notice a leak, you need to replace the oil seal and apply a fresh coat of oil on the gearbox assembly.

  1. Take out the gearbox cover, located at the footrest. Ensure that the deck is oriented as it would be for normal use
  2. Ensure that you prevent contaminants from getting into the gearing by cleaning the area around the cover plates
  3. Take off each of the screws that secure the cover plates on the gearing’s housing
  4. Inspect the oil level within each of the gearboxes – if it’s too low, fill it up to the flat shaft
  5. If the lower gasket has been worn out or taken damage, replace it with a new one before reinstalling the gearbox cover.

How do I clean the air filter?

It’s critical that the air filter on your mower is inspected at least once in every 100 hours of operation – the filter must be replaced at least once after every 400 hours of operation, or if it has been excessively clogged or damaged. Depending on your operating conditions, you might need to replace your filter more or less often. Dusty conditions might require a new filter change after every 200 hours.

  1. Take off the engine air filter cover after unlatching it. Wash the cover thoroughly and ensure that it is in order.
  2. Pull out the canister containing the air filter’s main element. Break out the seal and roll filter out of the tube. While breaking out the filter’s seal, ensure that you use gentle up, down and sideways movements to minimize the amount of dust breaking free that dislodges in the gap.
  3. Initiate cleaning by gently tapping the filter element on a hard horizontal surface. If the amount of debris within the filter has not considerably reduced after this, the filter may need to be discarded.
  4. With the help of a bright flashlight, inspect the filter element for any damage that may have occurred. Damage can allow dirt to leak through the element so ensure that you carry out a thorough inspection.
  5. Inspect the surface of the sealant and ensure that there is no considerable damage here.
  6. Take out the safety filter and with the help of the clean damp cloth, wipe out the inside if the canister can. Ensure that you have cleaned the inside as well as the outside of the can.
  7. Gently insert the safety filter’s element and take care to apply pressure only on the firm outer rim – not at the center portion. After ensuring that the filter is completely secured in place, reinstall the filter’s cover.
  8. Now fasten the Engine air cleaner’s cover back in place. Latch both the covers.
  9. Inspect the intake hose for any damage in the form of cuts, nicks, cracks etc and replace if required. After this, reset the restriction gauge on the air filter

How do I clean the mower’s deck?

It’s important that you regularly clean grass discharge, clippings and other debris that would have accumulated on the deck. Ensure that you have turned off the engine and disconnected the spark plug before attempting any cleaning.

  1. The deck lock handle’s lever, located at each side of the frame on the carrier, must be pulled out to release the carrier frame – this allows it to be tilted.
  2. With the support of the carrier frame’s tilt handle, lift up the deck to the higher tilt-up position. Now ensure that you have inserted the deck’s hook securely into the tilt-up latch on the body of the tractor.
  3. Using a pressure washer and a scrapping tool, clean out the grass and debris from underneath the deck.
  4. Re-engage both of the deck’s locking levers after lowering the deck back to its normal operating position

How do I sharpen and replace the blades?

For optimal cutting, it’s important the you inspect the blades periodically. The most important factors to be observed are the straightness and sharpness, the cutting edge, and the blade’s balance – these will need to be inspected once in every 10 hours of use. If the blades are worn out or bent, they need to be replaced.

  1. Once the engine has been stopped and the spark plugs have been disconnected, raise the mower’s deck and service the blades.
  2. Just as with cleaning the deck, secure the deck in the tilt-up position and latch it in place.
  3. Before checking the blades, ensure that the PTO lever has been disengaged.
  4. Inspect the blades for their straightness – ensure that you rotate the blades to check each of them. Compare the blades and if they are bent, replace them.
  5. If the cutting edge of the blade has been nicked or become dull, it will need to be sharpened. Loosen the nut, lock washer and the other washer mounting the blade before using heavy padded gloves to remove the blade.
  1. Grind out the cutting edge of the blade until it has the same bevel as the original blade.
  2. Now inspect the balance of the blades by positioning it horizontally with the help of a blade balancing tool – you can also use a nail at the centre.
  1. With the wingtips pointing towards the housing of the assembly, mount the new blades. Reinstall the washer and other components that were removed prior to mounting the new blade.

How do I clean the spark plug?

The spark plug assembly and circuitry has to be inspected at least once in every 100 hours of operation. Ensure that the engine has been turned off before carrying out any work on the spark plug.

  1. Inspect the spark plug gap and reset it if required – ideally the gap needs to be at between 0.028 abd 0.032 inches for optimal ignition. Typically, the spark gap needs to be reset once a year.
  2. With the help of a wire brush, clean out the spark plug to remove any accumulated debris.
  3. Inspect the electrodes – if they have been burnt too short, you will need to replace the spark plug

How do I adjust the steering and control levers?

The steering levers can be adjusted up to a range of 3 inches for optimal driving comfort. It’s important that you find the right steering position in order to achieve a smooth cut as jerky movements can have a detrimental effect on your lawn. You can make these adjustments on your Walker mower even with the engine running.

  1. Loosen the lock nuts that are located at the pivoting point, and also the lock nut that holds the handle in its upright position.
  2. Adjust the handle by moving it to a comfortable position and then tighten both the lock nuts once again.
  3. To adjust the forward speed control lever, first ensure that it’s positioned in the upright position. Now loosen the lock nuts as with the steering lever.
  4. Adjust the position of the control lever as desired and then faster the jam nuts once again
