Maintenance
General Recommendations
•
Always observe safety rules when
performing any maintenance.
•
The warranty on this lawn mower
does not cover items that have been
subjected to operator abuse or
negligence. To receive full value from
warranty, operator must maintain the
lawn mower as instructed here.
•
All adjustments should be checked at
least once each season.
•
Periodically check all fasteners and make
sure these are tight.
WARNING:
Always stop the
motor and remove the push start
safety key before cleaning,
lubricating or performing any
repairs or maintenance on the
mower. Always remove the
battery to prevent accidental
starting. Always allow the
machine to cool before
maintaining the mower. Before
maintaining the battery charger,
always unplug it from the power
outlet.
Deck Care
WARNING:
To prevent serious
injury, do not use water to clean
the mower, battery or battery
charger. Do not use strong
detergents. Household cleaners
that contain aromatic oils such as
pine and lemon, and solvents
such as kerosene, can damage
plastic.
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.
1.
Remove any buildup of grass and leaves
on or around the motor (do not use
water). Wipe the mower clean with a dry
cloth.
2.
If debris is allowed to build up on the
underside of the machine, tilt the mower
forward or on its side and clean with a
suitable tool.
IMPORTANT:
Do not use a pressure washer or
garden hose to clean your mower. These may
cause damage to electric components or the
electric motor. The use of water will result in
shortened life and reduce serviceability.
Blade Care
WARNING:
When removing the
cutting blade for sharpening or
replacement, protect your hands
with a pair of heavy gloves or use
a heavy rag to hold the blade. Be
certain to remove the
battery(ies).
Periodically inspect the blade adapter for
cracks, especially if you strike a foreign object.
Replace when necessary. Follow the steps
below for blade service.
1.
Stop the motor and remove the push
start safety key.
2.
With the battery(ies) removed, turn the
mower on its side.
3.
Remove bolt (a) and blade bell
support (b) which hold the blade and
the blade adapter to the motor shaft.
See Figure 4-1.

4.
Remove blade (c) and adapter (d) from
the shaft. See Figure 4-1.
5.
Remove blade from the adapter for
testing balance. Balance the blade on
a round shaft screwdriver to check.
Remove metal from the heavy side until
it balances evenly. When sharpening the
blade, follow the original angle of grind.
Grind each cutting edge equally to keep
the blade balanced.
WARNING:
An unbalanced
blade will cause excessive
vibration when rotating at high
speeds. It may cause damage to
mower or may break causing
personal injury.
6.
Lubricate the motor shaft and the inner
surface of the blade adapter with light
oil. Slide the blade adapter (d) onto
the motor shaft. Place the blade on the
adapter such that the side of the blade
marked “Bottom” (or with part number)
faces the ground when the mower is in
the operating position. Make sure that
the blade is aligned and seated on the
blade adapter flanges.
See Figure 4-1 inset.
7.
Place blade bell support (b) on the
blade (c). Align notches on the blade bell
support with small holes in blade.
8.
Replace hex bolt (a) and tighten hex
bolt to torque: 450 in-lb (min.), 600 in
lb (max.).
To ensure safe operation of your mower,
periodically check the blade bolt for proper
torque.
Battery Charger Care
1.
Keep the battery charger clean and
clear of debris. Do not allow foreign
material into the charging dock or onto
the terminals. See Figure 4-2. Inspect
the battery charger for foreign material
before each use.

2.
Make sure the charger has not been
shorted by debris. Inspect the terminals
for soot and signs of melting. Do not
attempt to use a damaged charger.
Wall-Mounting The Charger
The battery charger can be mounted to a wall.
Use mounting fasteners (not included) capable
of supporting the combined weight of the
battery and battery charger. Wall-mounting
holes are located on the bottom of the charger.
See Figure 4-3.
