Belt Maintenance

Servicing the Alternator
Belt
Service Interval: Every 100 hours
Proper tension of the belt allows 10 mm (3/8 inch) of
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
Note:
Increase or decrease the alternator-belt
tension and tighten the bolts. Check the deflection of
the belt again to ensure that the tension is correct.

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
