MAINTENANCE
FUEL LINES
Check the fuel lines every 50 hours of operation.
If the clamp band is loose, apply oil to the band
screw, and securely tighten the band.
The fuel lines are made of rubber, and may
become worn whether the machine has been used
much or not. Replace the fuel lines and clamp
bands after every 2000 hours of operation.
FOR SAFETY: Keep fl ames and sparks away
from fuel system service area. Keep area well
ventilated.
Replace or repair all worn or damaged fuel lines
and clamp bands. Plug both ends with clean cloth
or paper to prevent dirt from entering the lines
when the fuel lines are not installed. Dirt in the fuel
lines can cause fuel injection pump malfunction.

fan belt pulley. Proper belt tension is 10 mm
(0.40 in) from a force of 4 to 5 kg (9 to 11 lb)
applied at the mid-point of the longest span.
Check and adjust the alternator/fan belt tension
every 100 hours of operation.
Check the alternator/fan belt tensioner for damage
after every 500 hours of operation.
FOR SAFETY: When servicing machine, avoid
moving parts. Do not wear loose jackets,
