light oil.

MAINTENANCE
CUTTING BLADE
WARNING: Be sure to disconnect
and ground the spark plug wire and
remove ignition key before working
on the cutting blade to prevent acci-
dental engine starting. Protect
hands by using heavy gloves or a
rag to grasp the cutting blades.
Tip mower as specified in separate engine
manual. If it is not specified tip with carbure-
tor up.
Remove the bolt and blade support which
holds the blade and adapter to the engine
crankshaft. Remove the blade and adapter
from the crankshaft.
WARNING: Periodically inspect the
blade adapter for cracks, especially
if you strike a foreign object. Re-
place when necessary.
For best results your blade should be sharp.
The blade may be resharpened by removing
it and either grinding or filing the cutting
edge keeping as close to the original bevel
as possible. It is extremely important that
each cutting edge receives an equal amount
of grinding to prevent an unbalanced blade.
Improper blade balance will result in exces-
sive vibration causing eventual damage to
the engine and mower. Be sure to carefully
balance blade after sharpening. The blade
can be tested for balance by balancing it on
a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly.
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. Install the blade
adapter on the crankshaft with the “star”
away from the engine. Refer to figure 11.
Place the blade with the side marked bottom
(or with part number) facing away from the
adapter. Align the blade bell support over
the blade with the tabs in the holes of the
blade and insert the hex bolt. Tighten the
hex bolt to the torque listed below:
Blade Mounting Torque
Center Bolt 450 in. lb. min., 600 in.lb. max.
To insure safe operation of your unit, ALL
nuts and bolts must be checked periodically
for correct tightness.
