Charging the Battery
Model 20796 only
Charge the battery for 24 hours initially, then only as needed
thereafter. Always use the charger in a sheltered area and
charge the battery at room temperature (70°F or 22°C)
whenever possible.
Note: The engine is equipped with an alternator. Running
the engine helps to maintain the battery charge during the
mowing season.
1. Connect the charger to the mower wire harness located
below the ignition key (Figure 38).
Important: Use only the charger supplied with
the mower.
Figure 38
2. Plug the charger into a wall outlet.
When the battery no longer holds a charge, recycle or
dispose of the lead-acid battery according to local codes.
Replacing the Fuse
Model 20796 only
If the battery does not charge or the engine does not turn
with the electric starter, the fuse may be blown. Replace
it with a 40-amp plug-in type fuse. Refer to Installing the
Fuse in Setup.
Lubricating the Wheel Gears
Lubricate each rear wheel with grease yearly.
1. Wipe the grease fittings just inside the rear wheels with
a clean rag (Figure 39).
Figure 39
2. Install a grease gun onto each fitting and gently apply 2
or 3 pumps of #2 multi-purpose lithium-base grease.
Replacing the Blade
Important: You will need a torque wrench to install
the blade properly. If you do not have a torque wrench
or are uncomfortable performing this procedure,
contact an Authorized Service Dealer.
Examine the blade whenever you run out of gasoline. If the
blade is damaged or cracked, replace it immediately. If the
blade edge is dull or nicked, have it sharpened or replace it.
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves when servicing the blade.
1. Disconnect the spark plug wire from the spark plug.
Refer to Preparing for Maintenance.
2. Tip the mower onto its side with the air filter up.
3. Use a block a wood to hold the blade steady (Figure 40).
