the unit under normal operating conditions. Therefore, no
further bearing lubrication is required.

wrapping the cutting edges of the blade with rags and
other material when performing blade maintenance.
Contact with the blade could result in serious personal
injury.
REPLACING THE CUTTING BLADE
See figure 10.
For best results, the mower blade must be kept sharp.
Replace a bent or damaged blade immediately.
WARNING
Only use replacement blades approved by the
manufacturer of your mower. Using a blade not approved
by the manufacturer of your mower is hazardous and
could result in serious injury, damage your mower, and
void your warranty.
WARNING
Drain the fuel first before tilting the mower to replace the
blade.
1. Stop the engine and disconnect the spark plug wire.
Allow blade to come to a complete stop.
2. Turn the mower on its side (carburetor facing up).
3. Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.

the blade bolt by turning the bolt in a counterclockwise
direction as viewed from the bottom of the mower.
5. Remove the blade bolt, lock washer, flat washer, and
blade.
6. Place the new blade on the shaft. Make sure it is
installed with the curved ends pointing up toward the
mower deck and not down toward the ground.
7. Replace the flat washer, lock washer, and blade bolt
on the shaft. Finger tighten the bolt by turning in a
clockwise direction as viewed from the bottom of the
mower.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
8. Torque the blade bolt down using a torque wrench (not
provided) to ensure the bolt is properly tightened.
9. The recommended torque for the blade bolt is 48–55

5. Replace and secure the air filter cover.
NOTE: The filter should be replaced annually for best
performance.
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and a
check valve. A clogged fuel cap will cause poor engine
performance. If performance improves when the fuel
cap is loosened, check valve may be faulty or clogged.
Replace fuel cap if required.
CHANGING THE ENGINE OIL
See figure 13.
Engine oil should be changed after every 25 hours of use.
Change the oil while the engine oil is still warm, but not hot.
This allows the oil to drain quickly and completely.

2. Tip mower onto its side and allow oil to drain from the oil
fill hole into an approved container.
3. Place mower upright and refill with oil.
