Operating Instructions
NOTE: 530M Haulpak Trucks are equipped with four
12 volt batteries connected in series and parallel to
provide 24 volt output. Be certain to maintain correct
voltage and polarity when connecting booster cables.
Damage to electrical components may result if voltage
and polarity are not correct.
AFTER ENGINE HAS STARTED
1. Become thoroughly familiar with steering and
emergency controls. Test the truck steering in
extreme right and left directions. If the steering
system is not operating properly, shut engine
down immediately. Determine the steering sys-
tem problem and have repairs made before re-
suming operation.
2. Operate each of the truck's brake circuits at least
twice prior to operating and moving the truck.
These circuits include individual activation from
the operator's cab of the service brake, retarder
control lever, parking brake switch, brake lock
switch, and emergency brake switch. Activate
each circuit individually with the engine running
and with the hydraulic circuit fully charged.
If any application or release of any brake circuit
does not appear proper or if sluggishness is ap-
parent on application or release, shut the engine
down and notify maintenance personnel. Do not
operate truck until brake circuit in question is fully
operational.
3. Check gauges, warning lights and instruments
before moving the truck to insure proper system
operation and proper instrument functioning.
Give special attention to braking and steering
circuit warning lights. If warning lights come on,
shut down the engine immediately and determine
the cause.
4. Insure headlights, worklights and taillights are in
proper working order. Good visibility may prevent
an accident. Check operation of windshield wiper
and washer.
5. When truck body is in dump position, do not allow
anyone beneath it, unless body-up retaining de-
vice is in place.
6. Do not use the fire extinguisher for any purpose
other than putting out a fire! If extinguisher is
discharged, report the occurrence so the used
unit can be refilled or replaced.
7. Do not allow unauthorized personnel to ride in the
truck. Do not allow anyone to ride on the ladder
or on the deck of the truck.
8. Do not leave truck unattended while engine is
running. Shutdown engine before leaving cab.
MACHINE OPERATION SAFETY
PRECAUTIONS
After the truck engine is started and all systems are
functioning properly, the operator must follow all local
safety rules to insure safe machine operation.
If any of the red warning lights come ''On'' or if any
gauge reads in the red area during truck operation,
a malfunction is indicated. Stop truck as soon as
safety permits, shut down engine if problem indi-
cates and have problem corrected before resum-
ing truck operation.
1. Always sound the warning horn before moving the
truck. When backing the truck, give back-up sig-
nal (three blasts on horn); when starting forward,
two blasts on horn. These signals must be given
each time the truck is moved forward or back-
ward. Look to the rear before backing the truck.
Watch for and obey ground spotter's hand signals
before making any reverse movements. Spotter
should have a clear view of the total area at the
rear of the truck.
2. Operate the truck only while properly seated with
seat belt fastened. Keep hands and feet inside the
cab compartment while truck is in operation. Keep
a firm grip on steering wheel at all times.
3. Check gauges and instruments frequently during
operation for proper readings.
4. Observe all regulations pertaining to the job site's
traffic pattern. Be alert to any unusual traffic pat-
tern. Match the truck speed to haul road condi-
tions and slow the truck in any congested area.
Obey the spotter's signals at shovel and dump.
5. Do not allow engine to run at ''Idle'' for extended
periods of time.
6. Check parking brake periodically during working
shift. Use parking brake for parking only.
Do not attempt to apply parking brake while truck
is moving!
7. Apply the Brake Lock Switch at the shovel and
dump areas.
8. Proceed slowly on rough terrain to avoid deep ruts
or large obstacles. Avoid traveling close to soft
edges and the edge of fill area.
9. Truck operation requires concentrated effort by
the driver. Avoid distractions of any kind while
operating the truck.
