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 Cleaner System
NOTE: The following inspection is only an exter-
nal inspection and should be done without “dis-
turbing” the ltration components.
On a daily basis, visually inspect the external condi-
tion of the complete air cleaner system. The follow-
ing 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 tight-
ness.
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, re fer
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 sys-
tems.
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 bat-
tery 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 per-
forming any welding on equipment.
Electrolyte Level
The battery electrolyte level should be checked af-
ter every 25 hours of operation. To check electro-
lyte 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 wa-
ter 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 overll the battery. Electro-
lyte will overow through the vented caps onto parts
of the machine and WILL result in severe corrosion.
