3. If the coolant level is low, add a 50/50 mixture of
water and ethylene glycol anti–freeze. Do not
overfill.
Important:
Do not use water only or
alcohol/methanol base coolants.
4. Install the radiator and expansion tank caps.
Removing Debris from the
Cooling System
Service Interval: Before each use or daily—Remove
debris from the screen, oil coolers,
and radiator (more frequently in dirty
operating conditions).
1. Turn the engine off and remove the key from the
ignition switch.
2. Release the front engine cover latches and raise
the engine cover.
3. Thoroughly clean all debris out of the engine
area.
4. Clean both sides of the oil cooler, radiator and
rear engine area thoroughly with compressed
air.
5. Lower the engine cover and secure the latches.

Belt Maintenance

Check the condition and tension of the alternator belt
after the first day of operation and every 100 operating
hours thereafter.
Checking the Condition and
Tension of the Alternator
Belt
Service Interval: Every 100 hours

•
Proper tension will allow a 10 mm (3/8 inch)
deflection when a force of 4.5 kg (10 lb) is applied
on the belt midway between the pulleys.
•
If the deflection is not 10 mm (3/8 inch), loosen the
alternator mounting bolts
decrease the alternator belt tension and tighten
the bolts.
Note:
Check deflection of belt again to ensure
that the tension is correct.
