MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken, or destroy plastic which may result in serious personal injury.

Periodically check all nuts and bolts for proper tightness to ensure safe operation of the mower.

Remove any buildup of grass and leaves on or around the motor cover. Wipe the mower clean with a dry cloth occa- sionally. Do not use water.

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. Fail- ure to heed this warning could result in serious personal injury.

WARNING:

Before performing any maintenance, make sure the mower is unplugged from the power supply. Failure to heed this warning could result in serious personal injury.

NOTE: Only use identical replacement blades.

Stop the motor and disconnect the power supply. Allow the blade to come to a complete stop.

Turn the mower on its side.

Wedge a block of wood between the blade and mower deck to prevent the blade from turning.

Loosen the blade nut using a 15 mm wrench or socket (not provided).

Remove the blade nut, spacer, blade insulator, and blade.

Make certain the fan assembly is pushed completely against the motor shaft.

LUBRICATION

Lubricate the springs on the rear discharge door with light oil.

Lubricate the height adjustment lever and related hardware with light oil.

Remove the wheels and lubricate the surface of the axle

bolt and the inner surface of the wheel with light oil.
