Sharpening the Blade
To sharpen the blade, first remove the blade as outlined
in the previous section. DO NOT attempt to sharpen the
blade while it is attached to the mower. The blade can
be sharpened with a file or on a grinding wheel.
•
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.
•
Test the blade by balancing it on a round shaft
screwdriver or a blade balancer as shown in Figure
15.
1. Insert screw driver through hole
\
2. Balanced blade will be parallel to ground

If the blade is not balanced, remove metal from the
heavy side until it balances evenly.

WARNING:
An unbalanced blade will
cause excessive vibration when rotating at
high speeds. It may also cause damage to the
mower and could break, causing personal
injury.
•
Reinstall the blade as described earlier in this
section making certain to torque the cutting blade to
specifications.
MowerDeck

WARNING:
To reduce the risk of electric
shock, do not expose the mower to water.
The underside of mower deck should be cleaned after
each use as grass clippings, leaves, dirt and other
debris will accumulate. This accumulation of grass
clippings, etc., is undesirable as it will promote rust and
corrosion.
•
Remove any buildup of grass and leaves on or
around the motor cover (do not use water). Wipe
the mower clean with a dry cloth occasionally.
•
If debris is allowed to build up on the underside of
the unit, tilt the mower forward or on its side and
scrape it clean with a suitable tool.
Lubrication
At the beginning and end of each mowing season:
•
Lubricate the springs on the rear discharge door
with a light oil.
•
Remove the wheels and lubricate the surface of the
axle bolt and the inner surface of the wheel with
light oil.
SECTION 9: OFF-SEASON S TORAGE
The following steps should be taken to prepare the lawn
mower for storage.
•
Make certain the power supply is disconnected.
•
Clean mower as instructed in previous section.
•
Inspect and replace/sharpen blade if required.
Refer to Cutting Blade section on page 14.
•
Lubricate mower following instructions on page 15.
•
Store mower in a dry, clean area. Do not store next
to corrosive materials, such as fertilizer and rock
salt.
•
Wipe extension cord to remove any foreign
substance such as oil or stains. Replace extension
cord if cut or damaged in any way.
•
Wind cord in a series of equal loops on each side of
your hand to prevent snarling.
•
Store mower indoors, in a cool, dry place, out of
reach of children. Do not cover lawn mower with a
solid plastic sheet. Any plastic covering traps
moisture around the mower which promote rust and
corrosion.
