14 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. For more detailed information, refer to the website for
your unit. Remain alert for unusual noises, as they could be
signaling a problem. Visually inspect the machine for any
abnormal wear or damage.
14.1 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.
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.
Never work with blades while key is in the ignition switch.
Turn key to "OFF" position, remove the battery packs from
the machine. 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!

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 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.
• 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.
