Section 3: Operation
Theory of Operation
The flameless heater generates heat by running pressur-
ized fluid through a restrictive orifice, which drops the
hydraulic pressure and results in heated fluid. A fan then
blows air over the heat exchanger to push heated air out
through the heat ducts.
Before Starting Engine
Pre-Start Checklist
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.
•
Remove all flammable materials and fire hazards
within 5 ft (1.5 m) of the unit.
•
Keep unit a minimum of 10 ft (3 m) from structures
or barricades.
•
Verify the unit is not leaking fluids: check 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 the air duct hose is securely fastened to out-
let duct assembly.
•
Check fuel, engine oil, hydraulic fluid, and engine
coolant levels.
•
Verify unit is properly secure and level with the
parking brake engaged.
•
Inspect the alternator drive belt for tension and
abnormalities.
•
Verify battery cable connections are not loose or
corroded.
•
Inspect ducting for damage or unusual wear.
Owner's Manual for Flameless Heat Cart
Engine Oil Level Check
Engine damage. Verify proper type and quantity of
engine oil prior to starting engine. Failure to do so
could result in engine damage.
NOTE: Wait at least 10 minutes before proceeding if the
engine was running.
1. Remove oil dipstick from crankcase and wipe it
clean with a clean, lint free cloth.
2. Insert oil dipstick fully into oil dipstick tube and then
remove slowly.
3. Oil level must be between the FULL and ADD
marks on the oil dipstick.
(000108)
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 oil dipstick.
•
Reading oil dipstick before oil fully drains into oil
pan.
•
Inserting and removing oil dipstick too quickly.
•
Removing and reading the oil dipstick before fully
seating the oil dipstick into oil dipstick tube.
Hydraulic Oil Check
On the hydraulic fluid reservoir tank is a gauge showing
hydraulic oil level. Verify level is between MIN and MAX.
Engine Coolant Check
Risk of burns. Do not open coolant system
until engine has completely cooled. Doing so
could result in serious injury.
1. Remove radiator fill cap.
2. Check coolant level and degree of fouling. Level
should be approximately 0.39 in (10 mm) below the
radiator core top.
3. Install radiator cap securely.
