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.
13.1 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.
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!
DANGER
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.
WARNING
•
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.
13.1.1 REPLACE THE BLADE
Blade
Washer
Bolt
1. Turn key to “OFF” position, remove key from switch and
remove the batteries from the battery compartment under
the seat.
2. Lift the front of the mower and block and secure the
machine to allow serviceman to change the blade under
the mower.
3. While wearing leather padded gloves, grasp the blade
closely with one hand in order to prevent the blade from
turning and use a 24mm wrench with your other hand to
loosen the bolt fixing its blade in place.
4. Turn the bolt COUNTERCLOCKWISE to loosen and
CLOCKWISE to tighten.
5. Remove the bolt, washer and the blade.
13.1.2 INSTALL THE BLADE
1. Place the blade with the cutting blade toward the ground.
2. Install the bolt.
3. Turn the blade nut CLOCKWISE with a socket or wrench
to secure the blade.
13.2 TIRES
It is important for level mowing that all tires have the correct
amount of air pressure. The recommended pressure are:
NOTE
Tire pressure should only be measured or adjusted when
tires are cold.
Drive wheels
37±2 psi
Front caster wheels
8±2 psi
NOTE
Inspect the tires daily. Replace immediately if damaged.
WARNING
Check the tire pressure carefully while inflating. Too much
air in the tire could cause the tire to burst, causing serious
personal injury.
