7 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.
7.1 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 magnetic bar is in the
ignition switch. Remove magnetic bar from switch and
disconnect battery cables by pulling inward on RED battery
quick disconnect handle 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 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.

7.1.1 REMOVE THE BLADE
See figure 11-12
You can cut the grass in two differnt ways: Side discharge
blade and mulching blade. With the mulching blade, you can
cut the grass more intensively.
1. Remove the magnetic bar and disconnect battery cables
by pulling inward on RED battery quick disconnect
handle in battery box compartment.
2. Lift the front of the mower and block and secure the
machine to allow service man 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.
If you use the mulching blade, it is necessary for you to
install the two mulcher covers, and the side mulcher plate.
Otherwise, only install the side discharge chute.
7.1.2 INSTALL THE BLADE
1. Place the blade with the cutting blade toward the ground.
2. Install the bolt.
3. Turn the blade bolt CLOCKWISE with a socket or
wrench to secure the blade.
4. Thread the blade nut on the shaft and finger tighten.
5. Torque the blade nut down clockwise using a
torquewrench (not provided) to ensure the bolt is
properlytightened. The recommended torque for the blade
nut is 155-160N.m.
7.2 TIRES
It is important for level mowing that all tires have the correct
amount of air pressure. The recommended pressure are:
Tire pressure should only be measured or adjusted when
tires are cold.
Drive wheels
Front caster wheels
Inspect the tires daily. Replace immediately if damaged.
