LUBRICATION
All of the bearings in this product are lubricated with
a suffi cient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore, no
further bearing lubrication is required.
WARNING
Always protect hands by wearing heavy gloves and/or
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 fi gure 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 fi rst 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.

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
Nm (35–40 ft.lb.).

A leaking fuel cap is a fi re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable fi lter and a
