WHEN REPAIRS ARE NECESSARY
1. Only qualified maintenance personnel who under-
stand the systems being repaired should accom-
plish repairs.
2. Many components on the HAULPAK
large and heavy. Insure that lifting equipment -
hoists, slings, chains, lifting eyes - are of adequate
capacity to handle the lift.
3. DO NOT WORK under a suspended load. Do not
work under raised body unless body safety ca-
bles, props, or pins are in place to hold the body
in up position.
4. Do not repair or service truck while engine is
running, except when adjustments can only be
made under such conditions. Keep a safe dis-
tance from moving parts.
5. When servicing any air conditioning system with
refrigerant, wear a face shield and cold resistant
gloves for protection against freezing. Be certain
to follow all current regulations for handling and
recycling refrigerants.
6. Follow package directions carefully when using
cleaning solvents.
7. If an auxiliary battery assist is needed, first use one
cable to connect the 24V positive (+ ) post of the
disabled truck batteries to the 24V positive (+ )
post of the auxiliary assist. Use second cable to
connect the 24V negative (-) post of the auxililary
assist battery to a frame ground (-) on the dis-
abled truck away from the battery.
8. Always disconnect the positive and negative bat-
tery cables of the vehicle before doing any weld-
ing on the unit. Failure to do so, may seriously
damage the battery and electrical equipment.
Disconnect battery charging alternator lead wire
and isolate electronic control components before
making welding repairs.
Refer to the welding "Caution" plate located in the
cab above the windshield. These instructions
MUST be followed when welding is done on the
truck to avoid damage to the ATEC components.
Always fasten the welding machine ground (-)
lead to the piece being welded; grounding clamp
MUST BE ATTACHED AS NEAR AS POSSIBLE
to the weld area. Never allow welding current to
pass through ball bearings, roller bearings, sus-
pensions, or hydraulic cylinders. Always avoid
laying welding cables over or near the vehicle
electrical harnesses. Welding voltage could be
induced into the electrical harness and possibly
cause damage to components.
9. If truck is to be towed for any reason, use a rigid
tow bar. Check truck cab for decal recommending
special towing precautions. (Also refer to Towing
Procedure in OPERATING INSTRUCTIONS.)

10. Drain, clean and ventilate fuel tanks and/or hydrau-
lic tanks before making any welding repairs.
Any operating fluid, such as hydraulic oil or brake
fluid escaping under pressure, can have sufficient
force to enter a person's body by penetrating the
skin. Serious injury and possibly death may result
if proper medical treatment by a physician familiar
with this injury is not received immediately.
11. Relieve pressure in lines or hoses before making
any disconnects.
12. After adjustments or repairs, replace all shields,
screens and clamps.
13. Tire Care:
Do not stand in front of rim and locking ring when
inflating tire mounted on the machine. Observers
should not be permitted in the area and should be
kept away from the side of such tires.
Do not weld or apply heat on the rim assembly with
the tire mounted on the rim. Resulting gases inside
the tire may ignite, causing explosion of tire and
rim.
14. Only a qualified operator or experienced mainte-
nance personnel who are also qualified in opera-
tion should move the truck under its own power
in the repair facility or during road testing after
repairs are complete.
