15 MAINTENANCE
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis. Remain alert for unusual noises, as they could
be signaling a problem. Visually inspect the machine for
any abnormal wear or damage.
15.1 MOWER BLADE MAINTENANCE
Check the mower blades daily. They are the key to
power efficiency and well-groomed turf. Keep them
sharp -- a dull blade will tear rather than cut the grass,
leaving a brown ragged top on the grass within a few
hours. A dull blade also requires more power. Replace
any blade that is bent, cracked or broken.
WARNING
Never attempt to straighten a bent blade by heating,
or weld a cracked or broken blade as the blade
may break and cause serious injury. Replace worn or
damaged blades.
WARNING
Never work with blades while key is in the ignition
switch. Press push button to turn the mower OFF,
remove key fob from switch and disconnect battery
cables (P+) in battery box compartment. Block up
mower when you must work under it. Wear gloves
when handling blades. Always check for blade
damage if mower strikes a rock, branch or other
foreign objects!
DANGER
The blade adapter will come off when the blade cap
screw is removed. Touch-up sharpening can be done
with a file. Check the blades for balance following
grinding. A commercial balancing tool is available
through most hardware supply stores, or balancing
can be done by placing the blade on an inverted line
punch or 12.7mm (1/2") bolt. Blade should not lean
or tilt. While spinning the blade slowly, it should not
wobble. If blade is out of balance, true it up before
reinstalling. Lay the blade on a flat surface and check
for distortion. Replace any distorted blade.
English
• The blade sail (curved part) must be pointing
upward toward the inside of the deck to ensure
proper cutting.
• When mounting blades, rotate them after
installation to ensure blade tips do not touch each
other or sides of the mower.
• Failure to correctly torque the bolt may result in the
loss of the blade, which can cause serious injury.
• Mower blades are sharp and can cut. Wear gloves
and use extra caution when servicing them.
