Maintenance
4.9 — Maintenance Tasks
4.9.1— Visually Inspect Unit
Perform a visual inspection of the unit periodically. If problems are found contact your local authorized service dealer.
Look for the following:
•
Any debris, trash, grass or weed growth, which would obstruct the flow of cooling air into and out of the unit ven-
tilation louvers.
•
Visually inspect hoses and hose connections for signs of leakage. This includes all coolant hoses, fuel hoses,
exhaust system connections, intake system connections, etc. Also look at the engine block and gearbox (if
equipped) for signs of fluid leakage.
•
Visually inspect the engine accessory drive belts for evidence of obvious wear, fraying or deterioration, and obvi-
ous looseness. A "squealing" sound heard during starting and running could indicate a loose belt.
4.9.2— Check Engine Fluids
The following checks can be performed by a trained authorized operator. Observe all safety precautions outlined in the
"Safety" section.
4.9.2.1—Check Engine Oil Level
An authorized operator should check the levels of engine oil and engine coolant monthly (or every 24 hours of opera-
tion). The oil level should be maintained between the "FULL" and "ADD" marks on the engine dipstick. Recommended
fluids are listed in Subsection 2.6.2.
To check the engine oil:
Locate the engine oil dipstick.
1.
The most accurate oil level readings are measured when the engine is cold. If the engine was running, wait at
2.
least 10 minutes before proceeding.
Remove the dipstick and wipe it dry with a clean, lint free cloth.
3.
Slowly insert the clean dipstick into the tube. Visually confirm that the dipstick is fully seated in the dipstick tube.
4.
A visual inspection is required because some dipsticks will require more effort than others to fully seat.
After 10 seconds remove the dipstick.
5.
Look at the oil level on both sides of the dipstick. The lower of the two readings will be the correct oil level mea-
6.
surement.
Add oil (if necessary) to adjust the level. After adding or changing the oil, the engine should run for one minute
7.
before checking the oil level. Remember to wait 10 minutes to allow the engine to cool and oil to fully drain into
the oil pan.
Typical causes of inaccurate oil level readings:
•
Reading the high level of the dipstick.
•
Reading the dipstick before the oil fully drains into the oil pan.
•
Inserting and removing the dipstick too quickly.
•
The dipstick is not fully seated in the dipstick tube.
