LUBRICATION
_ ARNING: Always stop engine and disconnect spark plug wire before cleaning, lubricating or doing any
kind of work on lawn mower.
Blade Control
Lubricate the pivot points on the blade control handle and the brake cable at least once a season with light oil. See
Figure 12. The blade control must operate freely in both directions.
Chute Deflector
Lubricate the torsion spring and pivot point periodically with light eil to prevent any rust or binding. Deflector must
work freely.
Wheels
If your lawn mower has ball bearing wheels, lubricate at least once a season with light oil (or engine oil). Also, if the
wheels are removed for any reason, lubricate the surface of the axle bolt and the inner surface of the wheel.
Engine
Follow engine manual for lubrication instructions.
Transmission
The transmission is pre-lubricated and sealed at the factory. It does not require checking. If disassembled for any
reason, fillwith 2 ounces of Alvania grease, part number 737-0168.
_ ARNING: Be sure to disconnect and ground the spark plug wire before performing any repairs or
maintenance.
CUTTING BLADE
_ ARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object.
Replace when necessary.
When removing the cutting blade for sharpening or replacement, protect hands by using heavy gloves or a rag to
grasp the cutting blade.
Sharpening Blade:
Follow the original angle of grind as a guide. Make sure that each cutting edge receives an equal amount of grinding
to prevent an unbalanced blade.
NOTE: An unbalanced blade will cause excessive vibration when rotating at high speeds, may cause damage to
the mower and could break, causing personal injury.
Test the blade by balancing it on a round shaft screwdriver or a blade balancer. If the blade is not balanced, remove
metal from the heavy side until it balances evenly. We recommend that the blade be always removed from the
adapter for the best test of balance.
Before reassembling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil (or engine oil). Also lubricate the crankshaft bolt.
