FOREWORD
This handbook is intended to provide the HAULPAK®operator with the necessary
information to allow for safe and efficient truck operation.
The HAULPAK®operator should be a qualified individual who has had proper training to
achieve full production with the truck. An efficient, qualified operator can help insure long
production life of the truck and avoid costly down time due to misuse of the unit and its
systems. Training for both operators and maintenance personnel is recommended and is
available upon request. Operator training is accomplished at the job site by qualified
operator instructors. Maintenance training is provided both in the factory setting and in
field schools. All requests for operator and/or maintenance training should be forwarded
to the local HAULPAK®Distributor for action.
This handbook shows dimensioning of U.S. standard and metric (SI) units, and all
references to "Right", "Left", "Front", or "Rear" are made with respect to the operator’s
normal seated position, unless specifically stated otherwise. Illustrations used in this
handbook are typically representative and may not necessarily depict a specific model.
A Product Identification plate is normally located on the frame in front of the right side front
wheel and designates the Truck Model Number, Product Identification Number (vehicle
serial number), and Maximum G.V.W. (Gross Vehicle Weight) rating.
The HAULPAK®Model designation consists of three numbers and one letter (i.e. 210M).
Thethreenumbersrepresentthebasictruckmodel.Theletter"M"designatesaMechanical
drive and the letter "E" designates an Electrical propulsion system.
The Product Identification Number (vehicle serial number) contains information which will
identify the original manufacturing bill of material for this unit. This complete number will
be necessary for proper ordering of many service parts and/or warranty consideration.
The Gross Vehicle Weight (GVW) is what determines the load on the drive train, frame,
tires, and other components. The vehicle design and application guidelines are sensitive
to the total maximum Gross Vehicle Weight (GVW) and this means the total weight:
the Empty Vehicle Weight + the fuel/lubricants + the payload.
To determine allowable payload:
Service all lubricants for proper level and fill fuel tank of empty truck (which includes all
accessories, body liners, tailgates, etc.) and then weigh truck.
Record this value and subtract from the GVW rating. The result is the allowable payload.
NOTE:Accumulationsofmud,frozenmaterial,etc.becomeapartoftheGVWandreduces
allowable payload. To maximize payload and to keep from exceeding the GVW rating,
these accumulations should be removed as often as practical.
Exceeding the allowable payload will reduce expected life of truck components.

MODEL 210M HAULPAK® TRUCK
HB-4 Introduction HB0010 7/95

COMPONENT DESCRIPTION AND SPECIFICATIONS
ENGINE
The 210M HAULPAK®Truck is powered by
a Cummins KTTA--19C diesel engine. It is
capableofspeedsup to 35MPH(56.7km/h).
TRANSMISSION
The diesel engine drives a remote-mounted
Allison CLT-6063 transmission incorporating
a TC683 torque converter. The transmission
has six "Forward" speeds and two "Reverse"
speeds and uses Allison Transmission Elec-
tronicControl(ATEC)forcompleteautomatic
shift sequencing.
The operator may select "R1" or "R2" for
Reverse, "N" for Neutral, or any one of the six
Forward driving ranges by using the Trans-
mission Range Selector. Each position (R2,
R1, N, D, 5, 4, 3, 2, 1) is selected by releasing
a range locking mechanism on the lever and
choosing the desired range. "D" will permit
completely automatic up and down shifts
through all six ranges. "5" will limit upshifts to
5th range only. "4" will limit upshifts to 4th
range only. "3" will limit upshifts to 3rd range
only. "2" will limit upshifts to 2nd range only.
"1" is a first range hold position and no up-
shifts are permitted.
"R1"or "R2"REVERSE position is used to
back the truck. "R1"position should be used
for normal reverse operation. This range se-
lection utilizes the standard 5.12:1 gear re-
duction ratio. "R2"position may be used for
job operations that would benefit from a
higher speed reverse operation. This range
selection utilizes a 3.43:1 gear reduction ra-
tio.
FINAL DRIVE
The Planetary Final Drive has full floating axle
shaftsandaplug-indifferentialcarrierassem-
bly.
SERVICE BRAKE SYSTEM
The service brakes are controlled by an all
hydraulic actuation system. Depressing the
service brake pedal actuates front dry disc
brakes and rear wet disc brakes.
Automatic Emergency Braking is provided if
system pressure falls below a preset value.
All functioning wheel brakes will be automat-
ically applied by accumulators.
DYNAMIC RETARDING
Dynamic retarding is actuated by depressing
the operator’s retarder pedal which applies
oil-cooled, rear mounted, wet disc brakes
only; the front brakes are not applied.
Application of the retarder pedal may be fully
modulated and should be used to slow the
truck during normal truck operation, to con-
trol speed coming down a grade or to make
non-emergency stops. Use of the retarder
pedal saves wear on the front brakes and
provides better steering control.
POWER STEERING
The HAULPAK®Truck is equipped with an
orbital power steering system mounted un-
der the cab floor with noise and vibration
isolators. An accumulator automatically pro-
vides emergency power to safely steer the
truck while stopping.
INSTRUMENTS
The cab instrument panel displays for the
operator all switches and gauges which are
necessary to safely control the truck and
monitor the truck’s operating systems.
SUSPENSION
HYDRAIR®IIsuspensioncylinderslocatedat
each wheel provide a smooth and comfort-
able ride for the operator and dampens
shock loads to the chassis during loading.

GENERAL SAFETY
Safety records of most organizations will show that the greatest percentage of
accidents are caused by unsafe acts of persons. The remainder are caused by
unsafemechanicalorphysicalconditions.Reportallunsafeconditionstotheproper
authority.
The following safety rules are provided as a guide for the HAULPAK®operator.
However, local conditions and regulations may add many more to this list.
SAFETY IS THINKING AHEAD
Prevention is the best safety program. Prevent a potential accident by knowing the
employer’s safety requirements, all necessary job site regulations as well as use
andcareofthesafety equipment on the HAULPAK®Truck.Onlyqualifiedoperators
or technicians should attempt to operate the HAULPAK®Truck.
Safe practices start before the operator gets to the equipment!
1. Wear the proper clothing. Loose fitting clothing, unbuttoned sleeves and
jackets, jewelry, etc., can catch on a protrusion and cause a potential hazard.
2. Always use the personal safety equipment provided for the operator such as
hard hat, safety shoes, safety glasses or goggles. There are some conditions
when protective hearing devices should also be worn for operator safety.
3. When walking to and from the truck, maintain a safe distance from all machines
even if the operator is visible.
At The Truck - Ground Level Inspection
4. Before operating truck, a careful visual inspection should be completed. Report
any items that need attention to the proper authority.
a. Visually inspect all headlights, worklights, clearance lights, and taillights for
damage and be certain lenses are clean. Good visibility may prevent an
accident.
b. Visually inspect entire truck for oil or coolant leaks, and loose nuts and bolts,
especially at the load carrying areas, such as: wheels, suspensions, steering,
and brakes.
If engine has been running, allow coolant to cool before removing the fill cap or
draining radiator.
Any operating fluid, such as hydraulic oil, or engine coolant escaping under pressure,
can have sufficient force to enter a person’s body by penetrating the skin and cause
serious injury and possibly death, if proper medical treatment by a physician who is
familiar with this type of injury is not received immediately.
HB2002 4/94 General Safety Rules HB2-1

c. When checking coolant in radiator, relieve pressure before removing radiator
cap.
Do not stand in front of rim and locking ring when inflating tire.
d. Check tires for cuts, damage or ‘‘bubbles’’. Check tires for proper inflation. If
tire is warm from operation, allow tire to cool before adjusting tire pres-
sure. If inflation is needed, use an air chuck with extension hose clipped on
the tire inflation valve to allow service from behind the tread of the tire and
away from front of wheel.
e. Clean ladder and handrails of any foreign material such as ice, snow, mud or
oil.
f. Upon completion of an exterior inspection of the truck, clean mud, grease, or
snow from shoes before climbing access ladder.
Preparing For Operation
Always mount and dismount facing the truck. Never attempt to mount or dismount the
truck while it is in motion.
5.Always usehandrails andladder whenmounting ordismounting fromthe truck.
6. Check the deck areas for debris, loose hardware or tools.
7. Become familiar with all protective equipment devices on the truck and insure
that these items (anti-skid material, grab bars, seat belts, etc.) are securely in
place.
8. Read and understand the contents of this handbook. Read the sections
pertaining to safety and operating instructions with special attention. Become
thoroughly acquainted with all gauges, instruments and controls before at-
tempting operation of the truck.
Read and understand WARNING and CAUTION decals in the operator’s cab.
9. Keep all unauthorized reading material out of truck cab.
10. Do not carry tools and supplies or allow trash to accumulate in cab of truck.
HB2-2 General Safety Rules HB2002 4/94

11. Insure steering wheel, horn, controls and pedals are free of any oil, grease or
mud.
12. Insure headlights, worklights and taillights are in proper working order.
13. Insure windshield and all cab windows are clean and unbroken. Good visibility
may prevent an accident.
14. Check operation of windshield wiper, condition of wiper blades, and check
windshield washer reservoir for fluid level.
15. Be familiar with all steering and brake system controls and warning devices,
road speeds and loading capabilities, before operating the truck.
Truck Operation
16. DO NOT leave truck unattended while engine is running.
17. WEAR SEAT BELTS AT ALL TIMES. Only authorized persons are allowed to
ride in truck. Riders should be in cab only.
18. Do not allow anyone to ride on decks or steps of truck.
19. Do not allow anyone to get on or off truck while it is in motion.
20. Do not move truck into or out of a building without a signal person present.
21.Knowandobeythehandsignalcommunicationsbetweenoperatorandspotter.
When other machines and personnel are present, the operator should move in
and out of buildings, loading areas and through traffic, under the direction of a
signal person. Courtesy at all times is a safety precaution!
22. Report immediately to supervisor any conditions on haul road, pit or dump area
that may present an operating hazard.
23. Check for flat tires periodically during shift. If truck has been run on a ‘‘flat’’,it
must not be parked in a building until the tire cools.
If tire must be changed, do not stand in front of rim and locking ring when
inflatingtire mountedon themachine. Observersshould notbe permittedin the
area and should be kept away from the side of such tires.
24. Always have parking brake applied when the truck is parked and unattended.
25. When parking, park a safe distance from other vehicles as determined by
supervisor.
HB2002 4/94 General Safety Rules HB2-3

26. Keep serviceable fire fighting equipment at hand. Report used extinguishers for
replacement or refilling.
Tire and rim assembly may expode if subjected to excessive heat. Personnel should
move to a remote or protected location if sensing excessively hot brakes, smell of
burning rubber or evidence of fire near tire and wheel area.
If the truck must be approached, such as to fight a fire, those personnel should do
so only while facing the tread area of the tire (front or back), unless protected by use
of large heavy equipment as a shield. Stay at least 50 ft. (15 m) from the tread of the
tire.
In the event of fire in the tire and wheel area (including brake fires), stay away
from the truck at least 8 hours or until the tire and wheel are cool.
27.Stayalert atalltimes!Intheeventof an emergency,bepreparedtoreactquickly
and avoid accidents. If an emergency arises, know where to get prompt
assistance.
WHEN REPAIRS ARE NECESSARY
1. Only qualified maintenance personnel who understand the systems being
repaired should accomplish repairs.
2. Many components on the HAULPAK®Truck are large and heavy. Insure that
lifting equipment - hoists, slings, chains, lifting eyes - are of adequate capacity
to handle the lift.
3.DONOTWORKunderasuspendedload.Donotworkunderraisedbodyunless
body safety cables, 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 distance from moving
parts.
5. When servicing air conditioning system with refrigerant (Freon), wear a face
shield and cold resistant gloves for protection against freezing. Be certain to
follow all current requirements for handling and recapturing freon gas.
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 disabled truck away
from the battery.
HB2-4 General Safety Rules HB2002 4/94

8.Alwaysdisconnectthepositiveandnegativebatterycablesofthevehiclebefore
doinganyweldingontheunit.Failuretodosomayseriouslydamagethebattery
and electrical equipment. Disconnect battery charging alternator lead wire and
isolate electronic control components before making welding repairs. It is not
necessary to disconnect or remove any control circuit cards on electric drive
HAULPAK®Trucks or any of the "AID" circuit control cards.
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, suspensions, or hydraulic cylinders. Always avoid laying welding
cables over or near the vehicle electrical harnesses. Welding voltage could be
inducedintothe electricalharnessandpossiblycausedamageto 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 Proce-
dure in OPERATING INSTRUCTIONS.)
10. Drain, clean and ventilate fuel tanks and/or hydraulic 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 maintenance personnel who are also
qualified in operation should move the truck under its own power in the repair
facility or during road testing after repairs are complete.
