ing system is filled with a 50% mixture of ethylene gly-
col and water.
1.4 Radiator for Leakage and Dirt:
If necessary clean the radiator cooling fins with com-
pressed air and / or water. (40 psi [27 kPa] max) Dirt
buildup on the radiator cooling fins can cause both
engine and hydraulic system overheating.
1.5 Fan Belt Tension and Condition:

1.7 Air Intake and Cleaner System:
Follow the manufacturers inspection procedures.
Check that the filter indicator is not indicating that fil-
ter service is required.Section 7.1.
1.8 Exhaust System:
Visually inspect the exhaust system and ensure all
clamps are secure and the manifold bolts/nuts are tight.
Check muffler for carbon and soot build up and plug-

1.9 Engine Speed:
Check and if necessary adjust engine rpm Maximum no
load high idle: 3140 rpm.
1.10 Universal Joint:
Check the condition of the engine universal joints and
splines. Lubricate the u-joints with 2 ~ 3 pumps of
multi purpose grease. Section 7.1

If oil is visible in the oil level sight glass the level is
satisfactory.
If additional oil is required use only 10W30 API
classification SJ oil. Fill to the line marked next to the
sight gauge.
2.3 Hoses and Pipes:
Make a visual inspection of all hydraulic lines and fit-
tings for leaks. Check that steel lines do not touch one
another and clamps are tight.
2.4 Cylinders:
Inspect cylinders for leaks. Extend cylinders and
check for rod damage.
2.5 Hydraulic Functions:
Check that the following operate properly: control
valve float position, auxiliary hydraulic detent,
hydraulic cylinders.

API classification SJ- oil.
3.2 Drive Chain Condition:
Check drive chains for any sign of wear or damage.
Check lubrication oil in housing for signs of contam-
ination.
3.3 Hydrostatic Motor Mounting Bolts:
Check torque 80 ft lbs (108.2 Nm)
3.4 Axle Bearing End Play:
