Daily Inspection
Before putting the unit into service and each day before operating the unit,
always walk around unit and make the following checks:
Conveyor Belt
•General condition.
•Tension.
•Alignment–Belt centered on head and tail rollers.
Tires
•Check condition and pressure. Correct cold pressure is 35 PSI (2.4 kg/cm2) on
all tires.
Hydraulic System
Check level of hydraulic oil by observing sight gauge on hydraulic tank (behind
operator station).
Use Mobil DTE-13 in operating temperatures of +20OF – +120OF (-7OC –
+50OC).
Use Mobil Aero HFA (MIL-H-5606A) in operating temperatures of -25OF –
+50OF (-32OC – +10OC).
Important! Check hydraulic oil level with cylinders completely lowered
or overfilling might result, causing damage to the hydraulic
system.
Fuel Tank
Check fuel gauge on instrument panel (or on fuel tank) for sufficient fuel for the
day's operation.
Electrical System
Turn ignition switch to RUN position. Check that headlights, taillights, stoplights,
backup lights, and spotlights are operational.
Do not exceed bed capacity of 2,000 pounds distrib-
uted over total platform area or a 200 pound concen-
trated load.
CAUTION
The 35 psi cold tire pressure is for standard P225/75R15
radial tire only. Optional tires may have a higher pres-
sure. Check marking on tires to determine maximum inflation of optional
tires.

Engine and Transmission
1. With the transmission shift lever set in Neutral position and parking brake
set, turn ignition switch to the RUN position.
•Check that LOW VOLTS and LOW OIL PRESS indicators are illuminated.
•Check that HIGH WATER TEMP and BRAKE FAULT indicators flash briefly
and then go out.
2. Start engine and allow to warm up at idle speed for a few minutes.
Note: The engine starter will not engage unless the transmission shift lever is in
neutral position and no emergency stop buttons are pushed in.
Note: The instrument panel ignition switch is of the anti-restart type. Once the
engine has been cranked, the switch must be returned to "OFF" before
the engine can be cranked again.
Note: For diesel cold weather starting, refer to the next page.
3. Check operation of horn and power steering.
4. Check forward and reverse operation of conveyor belt from all operating
stations.
5. Check operation of conveyor lift, using the levers next to the operator’s
seat.
6. Raise the rear of the conveyor to the full up position. Raise the front and
position the safety stand as shown in Figure 2. Lower the front until the bed
barely rests on the stand and is captured between the tongues on the stand.
Be sure there is sufficient overhead clearance before
raising conveyor bed.

7. Stop engine.
8. Open engine cover.
9. Check engine oil level.
10. Check coolant level in radiator.
11. Check fuel filter for presence of water (diesel engines). Drain if necessary.
12. Check condition and tension of all drive belts.
13. Close engine cover, lower safety stand, and lower bed.
If all of the above checks are satisfactory, the unit is ready to service air-
craft. If trouble is discovered during any of the above checks, report the
problem to the proper maintenance personnel for correction before further
operation.
Diesel Engine Starting
Glow plugs should always be used to assist starting diesel engines at tempera-
tures below 70oF. (21oC.), and preferably above this temperature as well. With
some diesel engines, use of glow plugs is at the discretion of the operator, while
with others, a control circuit is built into the electrical system, that automatically
operates the glow plugs for a set period of time before permitting engine crank-
ing.
Where glow plug operation is manual, turn ignition switch to RUN, then hold glow
plug switch to "ON" for 20 seconds, then while still holding glow plugs "ON",
crank engine until it starts. Continue to hold glow plugs on for a few seconds after
engine starts until even running has been attained.
When glow plug operation is automatic, turn ignition switch to RUN. Glow plugs
and red pilot light on dash will go on. DO NOT crank until light goes out.
Note: It is possible to crank engine before light goes out, but this practice
should be avoided, unless restarting after short "engine off" intervals.
The use of ether or similar starting aids is not approved by Wollard Airport
Equipment Company.
Do not force the front lift down while it is on the safety
stand. Also, do not raise the rear lift while the front
rests on the safety stand. Either action may result in damage to the safety
stand.
CAUTION
Starting aids such as ether should
never
be used at
the same time as glow plugs.

Interlocks and Fault Indicators
•The engine starter will not engage unless the transmission shift lever is in neu-
tral, ignition switch is in RUN position, and no emergency stop buttons are
depressed.
•The instrument panel ignition switch is of the anti-restart type. Once the engine
has been cranked, the switch must be returned to OFF before the engine can be
cranked again.
•The conveyor belt drive function will not operate unless the transmission shift
lever is in neutral and the parking brake is set.
•Vehicle running and work lights operate only when the instrument panel ignition
switch is in RUN position.
Servicing Aircraft
How to Safely Approach the Aircraft
1. With the bed down, drive the unit to within approx. 10 feet (3 meters) of the
aircraft to be serviced. Position unit at right angles to door threshold.
2. Place transmission shift lever in Neutral position.
3. Raise front end of conveyor bed to approximate height of door threshold.
Raise aft end to working height of baggage carts.
4. Shift transmission into Drive position and slowly drive to within approx. 6
inches (15 cm) of threshold. Check alignment of conveyor bed with thresh-
old. Make any adjustments required. Place transmission lever in Neutral posi-
tion and set parking brake.
5. Adjust throttle for the desired operating speed of the conveyor belt drive.
Important! Belt will not operate unless shift lever is in Neutral and park-
ing brake is set.
6. Operate the belt from levers located on the left side of the conveyor bed,
both forward and aft.
Note: Electric pushbutton stations are optional.
This unit has restricted visibility on the right-hand side
and rear. Before moving unit, walk around and ensure
that there are no obstructions in the desired direction of movement. Be
extra cautious when driving in reverse or making right turns.
The operator position is forward of the front wheels. Be sure to compen-
sate for this by steering late. Make wide turns until you are accustomed to
driving the unit.
CAUTION
Be sure that shift control lever is secure in detent.

How to Safely Leave the Aircraft
1. Place transmission shift lever in reverse position, release parking brake and
slowly back unit a few feet (one or two meters) away from the aircraft.
2. Place shift lever in Neutral position while holding footbrake depressed.
3. Lower conveyor bed.
4. Continue depressing the footbrake pedal and place the transmission shift
lever in appropriate drive position, then release the footbrake and slowly
drive unit away.
Although it is possible to raise and lower the bed with the vehicle in motion, it is a
distraction to the driver and should therefore be attempted only by an experienced
operator and with the consent of the operations supervisor.
Be sure there is sufficient clearance around and under
the conveyor bed before lowering.
CAUTION
Do not use the conveyor bed as a lifting mechanism.
The conveyor is designed to support only 2,000
pounds distributed over total platform area or a 200-pound concentrated
load.
CAUTION
2/28/97
Do not stand on any area of the belt loader that is not specifically
designed to be stood on. Stand only on areas constructed with
"gripstrut" or otherwise covered with a skid-resistant surface.
Immediately repair any damaged gripstrut or skid-resistant material.
Do not ride on the belt loader except in a passenger seat.
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN
INJURY OR DEATH.

Emergency Shutdown
Complete engine shutdown can be done in emergency situations by pushing in
the red mushroom actuators at either end of the conveyor bed. The knobs must
be pulled back out before the engine will restart.
In Case of Engine or Hydraulic Pump Failure
Using the optional hand pump
An optional manually operated hydraulic pump is available to permit raising or
lowering either end of the conveyor bed in the event of engine or hydraulic sys-
tem failure. Location of the pump is just aft of the hydraulic tank behind the oper-
ator seat.
To operate the hand pump, remove handle from stowed position and insert over
pump actuator. The appropriate conveyor lift lever must be held in the desired
position while operating the pump handle. Conveyor will raise or lower while
manually pumping.
Important! Any time the pump is not being operated, the lanyard con-
nected to the pump body and looped around the groove in the
actuator must be in place. This will prevent the piston creep-
ing up due to system back pressure and protect against rust.
Towing the Conveyor Bed
If there is a failure in the engine/power train and the unit must be towed, retract
the stabilizers and disconnect the drive shaft (or raise rear wheels off the
ground). This will prevent damage to the transmission while towing. Towing
speed must not exceed 10 miles per hour.
