4. Assemble bolts, washers, and nuts in the exact
order of removal. Make sure to assemble the
fan properly
before running the mower. See
Figure 10.
:
WARNING
Periodically inspect the blade
adapter for cracks, especially if you strike
a foreign object. Replace when necessary.
Blade Mounting Torque
The recommended torque for the center blade bolt
is 450-600 in. lbs. The recommended torque for the
two blade adapter bolts is 200-350 in. lbs.
To insure safe operation of your unit, all nuts and
bolts must be checked periodically for correct
tightness.
Sharpening blade
1. The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen
while on the mower.
2. When sharpening the blade, follow the original
angle of grind as a guide. It is extremely
important that each cutting edge receives an
equal amount of grinding to prevent an
unbalanced blade.
3. Test the blade by balancing it on a round shaft
screwdriver or a blade balancer. Figure 11.
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.
4. 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
1. Insert screw driver through hole
2. Blade should be parallel to ground

5. When replacing the blade, be sure to install the
blade with the side of the blade marked
"Bottom" (or with part number) facing the
ground when the mower is in the operating
position. Also make sure to follow the correct
order as shown in Figure 10.
DECK
NOTE:
The underside of mower deck should be
cleaned after each use as grass clippings, leaves,
dirt
and
other
matter
accumulation of grass clippings, etc., is undesirable
as it will promote rust and corrosion.
1. Remove any buildup of grass and leaves on or
around the motor cover (do not use water).
Wipe mower clean with a dry cloth occasionally.
2. Disconnect the power source. Tilt the mower
forward or on its side and scrape clean with a
suitable tool.
