CHECKING/SERVICING
An additional procedure in maintaining transmission
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.

CHECKING/SERVICING
Engine Cooling System - MTL
Coolant Level
Model MTL 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 recovery tank.
If the coolant level is low, remove the radiator cap
and fill to the overflow port level and then fill the re-
covery 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 be-
fore putting it in the engine (adding pure antifreeze
into the radiator may cause damage to the engine by
causing overheating).
Security of Air Filtration Components
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 follow-
ing 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 both air intake hoses for cracks, nicks,
cuts, etc., and check the hose clamps for tight-
ness.
3. Check to make sure the air flow indicator is in
place and tight.
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.
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.
