If this machine is to be highway driven from one job site to
another, contact the stateand/or local authorities for roading
regulations.
MOVING DISABLED MACHINE
Towing
Towing articulated machinesisnot recommended.They have
no steering or braking power unlessthe engine will run to
drive the hydraulic steeringpump andair compressor.
MACHINE STORAGE
The following procedure is for chassisstorage only. For
engine storage instructions, refer to your Cummins Diesel
Operator's Manual.
When the machine is not to be usedfor a period of time,
store it in a dry and protected place. Leaving equipment
outdoors exposedto the elementswill materially shorten its
life.
Follow the procedure below when the machine is placed in
storagefor 30 daysor more. The machinemust be lubricated
every six months. Usecaution when starting an enginethat
has been in storage. Refer to the instructions under
"PREPARING STORED MACHINE FOR SERVICE" in this
section.
1.Thoroughly washor cleanthe machine.
2. Completely lubricate all points of the machineasoutlined
in the "LUBRICATION GUIDE" in Section 7.
3. Drain off the water from the fuel tank. Refer to "FUEL
SYSTEM" in Section 8.
NOTE: Be sure fuel tank contains minimum of five to
ten gallonsof approveddieselfuel.
4. Coverthe transmissionbreatheropeningwith tape.
5. If the cooling systemwill be exposedto freezing temper-
aturesduring storageand water only was usedduring opera-
tion, the cooling system must bedrained and refilled with an
anti-freeze solution while at operating temperature. Referto
"COOLING SYSTEM" in Section 8 to select a solution
suitable for the lowest temperature that the cooling system
will be exposedto during storage.
NOTE: If anti-freeze solution wasnot used,the residual
water retained by capillary attraction inside the cooler
passagesmust be blown out with dry compressedair
through thedrain valvein the oil cooler. DO NOT RELY
ONLY ON DRAINING THE WATER.
6. Completely service the air cleaners. Refer to "AIR
CLEANING SYSTEM" in Section 8.
7. Movethe machineto the storagearea.Lower the bucket to
the ground.
8. To prevent dirt or moisture from entering the engine,plug
up the endsof the exhaustpipe and crankcasebreather pipe.
Removethe air cleaner hood and coverthe air cleanerintake
pipe.
9. Openboth air tank drain valves.
10. Removethe batteriesand storethem in acool, dry place
above freezing (+32 degreesF.). The batteries must be fully
charged at the time of storage. Check the batteries at least
oncea month for water leveland specific gravity. Neverallow
the batteries to run down below 3/4 full chargewhile in
storage.
11. Coat the exposed portions of all cylinder rods and
control valvespoolswith chassisgrease.
12. If it isdesirableto leavethe tires on the machine,jack the
machine up and place it on blocks with the tires in
suspension.Deflate and coverthe tires.

PREPARING STOREDMACHINE FORSERVICE
The following procedure is for chassis only. For engine
instructions, referto your Cummins DieselOperator's Manual.
1. Inflate the tires. Check inflation pressure. Refer to
"SPECIFICATIONS AND CAPACITIES" in Section 9. Re-
move the blocks (if the machine wasjacked up). Lower the

7. Fill the fuel tank with agood gradeof fuel oil.
8. Checkthe air cleaner.Clean,if necessary.
9. Cleanthe chassisgreasefrom the exposedportions of the
cylinder rodsand control valvespools.
10. Check all lubricant capacities to be sure they areat the
proper levels.
11. Refer to Cummins Diesel Operator's Manual for pro-
cedure of restoring engine to service.
CAUTION: KEEP THE DOORSWIDE OPEN
OR MOVE THE MACHINE OUTSIDE THE
STORAGE ROOM IMMEDIATELY TO
AVOID DANGER FROM EXHAUST GAS. DO NOT
ACCELERATE THE ENGINE RAPIDLY OR OPERATE
IT AT HIGH SPEED IMMEDIATELY AFTER START-
ING.
•
12. When starting the engine, allow the engine to run at
part throttle for approximately five minutesto allow thorough
distribution of the lubricating oil. Do not place the machine
under load until normal oil pressure and temperature are
reached.
13. Operate the machine until the transmissionoil reaches
normal operating temperatures.

LUBRICATION WHEN SHIPPED
This machine has been lubricated at the factory for operation
in an air-temperature range of -10 degrees F. to 110 degrees
F. If the machine is to be operated above or below this
range, change to the correct lubricants. Unless an exception
is shown below, all lubricants can be used (within above
temperature range) until regular scheduled (normal) change
interval occurs. Refer to "SERVICE GUIDES" in Section 7
for the scheduled (normal) change intervals and to "LUBRI-
CANT SPECI FICATIONS AND CAPACITIES" for the proper
oil grades for various air temperatures.

This section covers the location and function of the various instruments and controls
of this machine. In the case of controls, more detailed information regarding opera-
tion can be found in Section 5.
Regardless of previous experience as an operator, you must
be thoroughly familiar with the location and use of all
instruments and controls before operating this machine.
Check all instruments, immediately after starting, again upon
reaching operating temperatures and at frequent intervals
during operation, to assure proper care through prompt
detection of irregularities. If any of the instruments do not
register properly, stop the engine; locate and correct the
cause immediately. Refer to "INSTRUMENT CHECK" in
Section 5.

CD EngineCoolant Temperature Gauge
This gaugeshowsthe temperature of the coolant circulating
through the engine.After the enginehasoperatedasufficient

During normal operation, the gauge readings should vary
between the minimum and maximum indicated by the
"RUN" segment of the gauge.
Continuous engine operation below the minimum tempera-
ture is harmful to the engine oil. Low coolant temperatures
will also causeexhaust smoke and increasethe rate of fuel
consumption.
NOTE: In cold weather, it may be necessaryto cover
part of the radiator to maintain the minimum coolant
temperature indicated at the lower end of the" RUN"
segment.
Overheating indicates the needfor mechanicalcorrection. A
cloggedcooling system or a low coolant level will alsocause
high operating temperatures. The enginetemperature, under
full-load conditions, should remain below the maximum
reading listed.

This fuse protects the rear driving lights circuit. Refer to
"ELECTRICAL SYSTEM" in Section 8 for additional
information on fuses.

on fuses.
CD Starting Aid Plunger (If equipped)
The starting aid plunger injects ether into the engine when
presseddown. The ether aids in starting the engine during
cold weather.
NOTE: The starting aid plunger should be used only
when the air temperature isbelow freezing (+32 degrees

a. Stop the engine. Check the oil level in the transmis-
sion (refer to Section 7 for the correct levelchecking
procedure).
b. Service the transmission filter. For filter servicing

®Voltmeter
The voltmeter indicates the condition of the batteries.When
the engineis not running or is running at low idle speed,the
gaugepointer should be within the left green area, which
indicates a good battery charge. If the voltage drops below
the left greenarea,the batteries should bechecked.With the
engine operating above low idle speed, the gauge pointer
should be within the right green area, which is the normal
operating range. If the voltage drops below the right green
area, the batteries and/or voltage regulator should be
checked. If the voltage exceedsthe right green area, the
