Operation
Section 3: Operation
Before Starting Engine
Pre-start Checklist
• Remove all flammable materials and fire hazards
within 5 ft (1.5 m) of unit.
• Keep unit a minimum of 5 ft (1.5 m) from structures
or barricades.
• Verify the unit is not leaking fluids: inspect inside
and outside the unit for leaking fuel, engine oil,
HTF/hydraulic oil, and engine coolant.
• Verify the following are clear of debris and obstruc-
tions:
– Engine air intake
– Engine exhaust stack
– Outlets and fan intakes
• Verify air duct hose is securely fastened to outlet
duct assembly.
• Check fuel, engine oil, and engine coolant levels.
• Verify unit is properly secure with jacks deployed (if
applicable), wheels chocked, and level.
• Inspect the alternator drive belt for tension and
abnormalities.
• Verify that the burner cover is securely installed.
• Inspect the generator. See the generator manual.
• Verify battery cables are not loose or corroded.
• Inspect ducting for damage or unusual wear.
Engine Oil Level Check
NOTE: If engine was running, wait at least 10 minutes
before proceeding.
1. Remove oil dipstick from crankcase and wipe it
clean with a clean, lint free cloth.
2. Slowly insert the clean oil dipstick into the oil dip-
stick tube. Verify the oil dipstick is fully seated.
3. After 10 seconds, remove the oil 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 add-
ing or changing the oil, run the engine for one min-
ute before checking the oil level. 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 oil dipstick.
• Reading the oil dipstick before the oil fully drains
into the oil pan.
• Inserting and removing the oil dipstick too quickly.
• The oil dipstick is not fully seated in the oil dipstick
tube.
Engine Coolant Check
Inspect the coolant sub-tank to check the coolant level.
Check the coolant level when the engine is cold, as cool-
ant flows to the sub-tank when the radiator is still hot,
which provides an inaccurate reading. Replace the cool-
ant according to the
Maintenance Schedule , or if it is
contaminated or dirty. See Adding Coolant .
Ducting Guidelines
•
Place ducting in desired configuration before oper-
ating the unit.
• Tightly secure ducting end to the unit. Verify any
additional ducting is also tightly secured.

WARNING
Hot Surfaces. When operating machine, do not
touch hot surfaces. Keep machine away from
combustibles during use. Hot surfaces could
result in severe burns or fire.
(000135)
CAUTION
Engine damage. Verify proper type and quantity of
engine oil prior to starting engine. Failure to do so
could result in engine damage.
(000154)
WARNING
Risk of burns. Do not open coolant system
until engine has completely cooled. Doing so
could result in serious injury.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.

DANGER
WARNING
Burn hazard. Do not remove ducting until all air
pressure has been emptied from hose duct.
Failure to do so could result in severe injury.
