CHECKING/SERVICING
DANGER
To prevent accidental starting of the en-
gine when servicing or adjusting the ma-
chine, remove the key from the ignition
switch and disconnect the spark plug
wires.
Security of Air Filtration Components
NOTE: The following inspection is only an external
inspection and should be done without “disturb-
ing” the ltration components.
On a daily basis, visually inspect the external condi-
tion of the complete air cleaner system. The following
items should be inspected:
1. Check the Cummins/Fleetguard OptiAir™ air
cleaner canister for damage. Make sure the
cover is in place and the cover latch is secure - do
not run the engine without the air cleaner cover
in place and secure.
2. Inspect the air intake hose for cracks, nicks, cuts,
etc., and check the hose clamps for tightness.
3. Check to make sure the air lter restriction gauge
is in place and hose connections are secure.
Battery
NOTE: For initial battery service during setup, refer
to Battery Service in Assembly Instructions.
IMPORTANT: Make sure battery is securely mount-
ed in the frame. A loose battery may cause damage
to the case resulting in acid leakage and severe dam-
age to the machine. A hazard may be created by
damage to critical working parts and safety systems.
CAUTION
Important Battery Service, Installation, and
Changing Tips for Electronic Fuel Injected
engines:
• Do not allow the battery cables to touch
opposing terminals. When connecting bat-
tery cables attach the positive (+) cable to
positive (+) battery terminal rst, followed
by negative (-) cable to negative (-) battery
terminal.
• Never start the engine when the cables
are loose or poorly connected to the battery
terminals.
• Never disconnect battery while engine is
running.
• Never use a quick battery charger to start
the engine.
• Never “jump start” the engine using an-
other source. Electricity uctuations can
damage the ECU (Electronic Control Unit).
• Always disconnect negative (-) battery
cable lead before charging battery, and also
unplug harness from ECU before perform-
ing any welding on equipment.
Electrolyte Level
The battery electrolyte level should be checked after
every 25 hours of operation. To check electrolyte
level:
1. Remove battery cell ller caps.
2. Check the electrolyte level. If the level is below
the bottom of the vent well, ll with drinking water
to the bottom of the vent wells [1/4 to 1/2 in.
(6 to 13 mm) above the plates].
3. Replace ller caps.
IMPORTANT: DO NOT overll the battery. Electro-
lyte will overow through the vented caps onto parts
of the machine and WILL result in severe corrosion.
