Operating Instructions
6. When getting a battery assist from one truck to
another, all switches must be "Off" prior to making
any connections. Be certain to maintain correct
polarity.
a. Connect one lead of booster cable to 24V posi-
tive (+ ) post of battery needing assist, and
other lead of the booster cable to the 24V posi-
tive (+ ) post of auxiliary battery.
b. Connect one lead of second booster cable to
24V negative (-) post of auxiliary battery, and
then connect other lead of the booster cable to
a good frame ground on the disabled truck
away from the battery needing assist.
This procedure will avoid the possibility of causing
sparks near the battery where explosive gases
may be present.

NOTE: HAULPAK
Trucks are generally equipped with
two 12 volt batteries connected in series to provide 24
volt output. Be sure to maintain correct voltage and
polarity when connecting booster cables. Damage to
electrical components may result if voltage and polar-
ity 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 of the
service brake, parking brake, brake lock (and
emergency brake if equipped) from the operator's
cab.
Activate each circuit individually with the engine
running and with hydraulic circuit (air circuit if
truck is equipped with air/hydraulic brakes) 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.
4. Give special attention to braking and steering
circuit warning lights. If warning lights come on,
shut down the engine immediately and determine
the cause.
5. Insure headlights, worklights and taillights are in
proper working order. Good visibility may prevent
an accident. Check operation of windshield wiper.
6. When truck body is in dump position, do not allow
anyone beneath it unless body-up retaining pin or
cable is in place.
7. 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.
8. 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.
9. Do not leave truck unattended while engine is
running. Shut down engine before getting out of
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 air horn); when starting for-
ward, two blasts on air horn. These signals must
be given each time the truck is moved forward or
backward. 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.
3. Check gauges and instruments frequently during
operation for proper readings.
