Caution
If the engine has been running, the pressurized,
hot coolant can escape and cause burns.
• Do not open the radiator cap when the engine is
running.
• Allow engine to cool at least 15 minutes or until
the radiator cap is cool enough to touch without
burning hand.
• Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
3. Remove radiator and reserve tank caps.

Adjusting Belts

Check condition and tension of all belts after first day of
operation and every 200 operating hours thereafter. Raise
bed (if so equipped) and position safety support on
extended lift cylinder to hold up bed.
Alternator belt
1. Check tension by depressing belt at mid span of
crankshaft and alternator pulleys with 22 lbs. of force.
A new belt should deflect .3–.5 in. A used belt should
deflect .4–.55 in. If deflection is incorrect, proceed to
next step. If correct, continue operation.
2. To adjust belt tension:
• Loosen (2) alternator mounting bolts.
