8. Radiator / Oil Cooler Service
With the engine cool, check the coolant level in the
overflow reservoir (fig. 4.3G). Ensure the coolant level is
at the Full-Cold mark on the reservoir by adding 50%
mixture of ethylene glycol and water if required.
The radiator and oil cooler fins must be kept free of debris
otherwise overheating of the engine will occur. Inspect the
radiator cooling fins for damage or buildup of debris.
Repair any damage and if necessary flush the radiator
with compressed air to remove debris.
4. 4 50 HOUR SERVICE CHECK
The following service check is to be performed by your
dealer after the first 50 hours of operation.
1 Engine
1.1 Oil and Filter:
Change the engine oil and filter. Use only original
replacement parts. Change the oil every 150 hours
thereafter. Change the filter every 300 hours
thereafter.
1.2 Radiator:
Check the coolant level. If necessary flush the radiator
with compressed air. A dirt buildup on the radiator
cooling fins can cause both engine and hydraulic
system overheating. Check the foam sealing ring on
the fan drive.
1.3 V-Belt Tension and Condition:
Check v-belt for cuts or wear, if necessary replace.
Check tension and adjust as shown in Section 4.8.4.
1.4 Fuel System for Leaks:
Make a visual inspection of fuel system for leaks and
potential hazards such as fuel line(s) touching exhaust
manifold, flywheel, etc. Replace fuel filter every 300
hours.
1.5 Air Intake and Cleaner System:
Visually inspect the air cleaner system and be sure all
hose clamps are secure and no hoses are damaged.
1.6 Exhaust System:
Visually inspect the exhaust system and ensure all
clamps are secure and the manifold bolts/nuts are tight.
1.7 Engine Speed:
Check engine speed and if adjustment is necessary,
contact a Thomas Equipment dealer.
4. MAINTENANCE
Keep the rear door
closed except for
servicing. Make sure the
door is closed and
latched before operating
the loader.
IMPORTANT
To avoid personal injury,
lower the lift arms, shut off
the engine, raise the seat bar
and cycle the hydraulics to
ensure they are locked. Then,
unlatch the seat belt and exit
the loader. Do not enter or
exit with the engine running
