Electrical System
Maintenance
Important: Whenever working with the electrical
system, always disconnect the battery cables, negative
(-) cable first, to prevent possible wiring damage from
short-outs.
Servicing the Battery
Service Interval: Every 50 hours
WARNING
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Keep the top of the battery clean. If you store the machine in
a location where temperatures are extremely high, the battery
will run down more rapidly than if the machine is stored in a
location where the temperature is cool.
Keep the top of the battery clean by washing it periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush the top surface with water after cleaning it.
Do not remove the fill caps while cleaning the battery.
The battery cables must be tight on the terminals to provide
good electrical contact.
If corrosion occurs at the terminals, disconnect the cables,
negative (-) cable first, and scrape the clamps and terminals
separately. Connect the cables, positive (+) cable first, and
coat the terminals with petroleum jelly.
WARNING
Battery terminals or metal tools could short against
metal machine components causing sparks. Sparks
can cause the battery gasses to explode, resulting
in personal injury.
• When removing or installing the battery, do not
allow the battery terminals to touch any metal
parts of the machine.
• Do not allow metal tools to short between
the battery terminals and metal parts of the
machine.
WARNING
Incorrect battery cable routing could damage the
machine and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
Storing the Battery
If the machine will be stored more than 30 days, remove the
battery and charge it fully. Either store it on a shelf or on the
machine. Leave the cables disconnected if it is stored on the
machine. Store the battery in a cool environment to prevent
the battery from discharging rapidly. To prevent the battery
from freezing, make sure it is fully charged. The specific
gravity of a fully charged battery is 1.265 to 1.299.
Checking the Fuses
The fuses are located under the control panel. Access them
through the side panel cover
panel cover, release the 2 latches and pull out on it.
If the machine stops or has other electrical system issues,
check the fuses. Grasp each fuse in turn and remove them
one at a time, checking to see if any are blown. If you need
to replace a fuse, always use the same type and amperage
rated fuse as the one you are replacing, otherwise you could
damage the electrical system (refer to the decal next to the
fuses
(Figure
46) for a diagram of each fuse and its amperage).
Note: If a fuse blows frequently, you probably have a short
in the electrical system and should have it serviced by a
qualified service technician.
