Owner’s Manual for Flameless Air Heater 13
Maintenance
Section 4 Maintenance
NOTE: Normal maintenance service and replacement of
parts is the responsibility of the owner and, as such, are
not considered defects in materials or workmanship
within the terms of the warranty. It is strongly
recommended that equipment be periodically checked by
an IASD.
Maintenance Tasks
Daily checks must be performed when unit is operated
continuously for extended periods of time. Daily checks
and routine monthly checks can be performed by an
authorized operator.
Daily Walk Around Inspection
Look for conditions that could hinder performance or
safety, such as (but not limited to) oil, coolant, fuel
leakage, blocked vents, loose or missing hardware and
electrical connections. Check for foreign matter blocking
the vents and on top of unit.
• Visually inspect outer cover for significant damage
beyond scuffs and small nicks.
• Visually inspect for wire abrasion.
• Visually inspect the fan belt for cracks, fraying and
stretching. Verify belt is properly seated in the
pulley grooves. Every 750 hours, it is
recommended that the belt be removed and
checked for wear. While belt is removed, inspect
pulleys and bearing. Rotate and feel for hard
turning or unusual sounds.
• Coolant should be checked daily.
• Check electrical connectors, battery and ground
points. Look for loose or missing hardware.
• Check all flexible rubber hoses for deterioration.
• Check hydraulic hoses for signs of wear.
• Verify hoses are not crushed, kinked or twisted.
• Verify there are no cracks or corrosion.
Check Engine Oil Level
NOTE: If engine was running, wait at least ten minutes
before proceeding.
1.
Remove dipstick and wipe it dry with a clean, lint
free cloth.
2.
Slowly insert the clean dipstick into the tube. Verify
the dipstick is fully seated in the dipstick tube.
3.
After ten seconds, remove the dipstick and look at
the oil level on both sides. The lower of the two
readings will be the correct oil level measurement.
4.
Add oil (if necessary) to adjust the level. After
adding or changing the oil, the engine should run
for one minute before checking the oil level. Wait
ten 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.
Drain the Oil
1.
Place container under drain port, or connect hose
or piping to drain port leading to container.
2.
Remove plug from oil drain.
3.
Open drain valve.
4.
See engine manual for oil filter information.
5.
Close drain valve.
6.
Remove hose or piping if applicable.
7.
Replace plug in drain port on sub base.
