CHECKING/SERVICING
DANGER
To prevent accidental starting of the engine
when servicing or adjusting the machine,
remove the key from the ignition switch
and disconnect the electrical plug on the
fuel shut-off solenoid.
Engine Cooling System
Coolant Level
WARNING
NEVER remove the radiator pressure cap
when the engine is hot — hot water could
spray and cause a burn if the cap is taken
off too soon.
Recovery Tank
Recovery (Overflow) Tank
Check the coolant level in the coolant recovery
tank and
maintain the coolant level between the
FULL and LOW marks on the recovery tank.
When the engine is cold, the coolant level should
be at or slightly above the
LOW
mark on the recov-
ery tank.
If the coolant level is low, remove the radiator cap
and fill to the overflow port level and then fill the
recovery tank above the
LOW
mark. Use a pre-
mixed 50/50 solution of antifreeze (ethylene glycol)
and distilled water to fill the cooling system.
IMPORTANT:
The coolant solution of antifreeze
and distilled water must be thoroughly pre-mixed
before putting it in the engine (adding pure anti-
freeze into the radiator may cause damage to the
engine by causing overheating).
Security of Air Cleaner System
NOTE:
The following inspection is
only an exter-
nal inspection
and should be done without
“dis-
turbing”
the filtration 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 Donaldson Radialseal™ air cleaner
canister for damage. Make sure the cover is
in place and the cover latches are secure—do
not run the engine without the air cleaner
cover in place and secure.
2. Inspect the air intake hose (into the engine) for
cracks, nicks, cuts, etc., and check the hose
clamps for tightness.
3. Check to make sure the air filter restriction
gauge is in place and securely mounted on the
air cleaner housing.
Battery
The battery comes sealed and is maintenance-
free, so the electrolyte level will not need to be
checked or filled.
IMPORTANT:
Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.
