Dealer for diagnosis and repair.
INITIAL RUN-IN PROCEDURES4.2
FIRST DAY OF USE OR APPROXIMATELY 20 HOURS
Change the engine oil and oil filter after the first 201.
hours of operation. (See Section 5.2).
Check for loose hardware. Tighten as needed.2.
Check tire pressure. Adjust pressure if necessary.3.
(See Section 5.5).
CONNECTING TO TOW VEHICLE4.3
Back the tow vehicle up to the truck loader.1.
Raise or lower the tongue jack until the pintle ring on2.
the truck loader is higher than the horn of the pintle
hook on the tow vehicle.
With assistance behind, back up slowly, align the3.
pintle ring and pintle hook.
Lower the front of the truck loader using the wheel4.
jack until the pintle ring drops completely onto the
pintle hook and securely lock.
Connect the safety chains to the tow vehicle in5.

STARTING THE ENGINE4.4
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.
Move the machine to a flat open area.1.
Be sure the fuel shutoff valve, located on the fuel2.
tank, is completely open. See Figure 4-1.
Move the engine throttle control to approximetly one-3.
fourth engine speed.
Turn the ignition key to the on position until the red4.
indicator for the glow plugs goes out. Then 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.
Allow engine to warm before operating the truck5.
loader.
OPERATION4.5
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
blower housing, wear liners, impeller and nose cone.
WARNING
DO NOT operate the machine without being
attached to a tow vehicle and debris box. Always
wear eye, ear and breathing protection when
operating machine.
Read Section 2.3 BEFORE OPERATION1.
CONSIDERATIONS and Section 2.4 OPERATION
CONSIDERATIONS before operating.
CAUTION
Tow at speeds appropriate for conditions. Reduce
speeds for:
• Rough Roads
• Winding Roads
• Cornering
• Adverse weather including rain, snow, ice and
high winds
Adjust the height of the intake nozzle. For maximum2.
debris pickup, the intake nozzle should be as close
to the debris as possible without blocking airflow and
the engine speed should be set at full throttle.
Not all debris pick up will require that the engine3.
speed be set to "Fast". You can experiment with the
intake nozzle height and engine speed to best suit
your conditions.
Operating in dry dusty conditions may require4.
that the engine speed be set to a slower position
to reduce the amount of small particles of debris
escaping.
For peak performance, keep the debris box clean5.
and do not overfill.
Make sure the driver of the tow vehicle has the6.
operator in full view at all times.

13
Section 4
When operating, instruct the operator to stay to the7.
side of the machine, never in front or behind.
WARNING
DO NOT remove the Truck Loader from the tow
vehicle or debris box with the engine running.
STOP the engine and allow all rotation to stop.
If the intake nozzle or discharge becomes plugged,8.
shut off the engine and remove the ignition key.
The engine must come to a complete stop before
attempting to remove obstruction from inlet nozzle
or discharge area. Using a stick or similar item,
dislodge the clogged material. Then resume normal
operation.
Plan how to clear the area to reduce clearing time.9.
Collecting debris into piles for the machine to10.
intercept prior to start up will save time and fuel as
well as wear and tear on the unit.
Keep the truck loader's intake nozzle and discharge11.
clean.
Use a slow travel speed when clearing heavy or12.
large amounts of material.
HILLSIDE OPERATION4.6
Slopes are a major factor related to loss-of-control and tip
over accidents which can result in severe injury or death.
All slopes require extra caution.
WARNING
DO NOT operate on steep slopes. Poor footing
could cause a slip and fall accident. ALWAYS
FOLLOW OSHA APPROVED OPERATION.
Do not operate on slopes if you are uneasy or1.
uncertain. Ultimate responsibility for safe operation
on slopes rests with the operator.
Be sure of footing on slopes.2.
Caution must be used when operating on slopes,3.
especially when the grass is wet. Wet grass reduces
traction and control.
To prevent tipping or loss of control, keep all4.
movements on slopes slow and gradual.
