Section 4
5. Intake Hose Boom Assembly (Figure 4-1). Used
to support the intake hose. The support chain can be
raised or lowered until the intake nozzle floats 2-3
inches from the ground to help make operation easy
and comfortable.
4.2 SAFETY INTERLOCK SYSTEM
The truck loader is equipped with a safety interlock system
that prevents the engine from starting unless the intake
hose assembly is attached to the truck loader. If the intake
hose assembly is removed, the impeller door will close and
the interlock system will shut off the engine.
WARNING
Never operate the truck loader with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to yourself
and others or property damage could result.
4.3 INITIAL RUN-IN PROCEDURES
FIRST DAY OF USE OR APPROXIMATELY 20 HOURS
1. Change the engine oil and oil filter after the first 20
hours of operation. (See Section 5.2).
2. Check for loose hardware. Tighten as needed.
3. Check tire pressure. Adjust pressure if necessary.
(See Section 5.5).
4.4 STARTING THE ENGINE
CAUTION
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a “runaway” engine condition
that could result in engine damage and/or
personal injury.
1. Move the machine to a flat open area.
2. Be sure the fuel shutoff valve, located under the fuel
tank, is completely open. See Figure 4-1.
3. Move the engine throttle control to about half engine
speed. If starting a cold engine, move the engine
control all the way forward to engage the choke.
4. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do
not hold the key in the START position for more
than 15 seconds at a time. Allow at least 60
seconds between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.
5. Allow engine to warm before operating the truck
loader.
4.5 OPERATION
This truck loader has been designed to pick up dry
organic debris such as leaves, grass clippings, shavings
and small amounts of sand. Vacuuming hard non-organic
material will affect the life of your machine. Sand is
abrasive and will produce wear of items including the
intake nozzle, intake hose, blower housing and impeller.
WARNING
DO NOT operate the machine without being
attached to a debris box. Always wear eye, ear and
breathing protection when operating machine.
1. Read Section 2.3 BEFORE OPERATION
CONSIDERATIONS and Section 2.4 OPERATION
CONSIDERATIONS before operating.
2. Adjust the height of the intake nozzle. For maximum
debris pickup, the intake nozzle should be as close
to the debris as possible without blocking airflow and
the engine speed should be set to "Fast".
3. Not all debris pick up will require that the engine
speed be set to "Fast". You can experiment with the
intake nozzle height and engine speed to best suit
your conditions.
4. Operating in dry dusty conditions may require
that the engine speed be set to a slower position
to reduce the amount of small particles of debris
escaping.
5. For peak performance, keep the debris box clean
and do not overfill.
6. Make sure the driver of the tow vehicle has the
operator in full view at all times.
