To the Owner
Your machine has been designed and built to the highest standards of quality. It conforms to all current safety
regulations. See “Official documents”. However, the risk of accidents can never be completely excluded. That
is why it is essential to observe elementary safety rules and precautions.
Read this manual carefully, paying particular attention to the instructions concerning safety, operation and
maintenance so as to avoid the risk of injury while operating or servicing the machine.
Use this manual as a guide. Your machine will remain a reliable working tool provided it is kept in good working
condition and serviced properly.
The standard attachments and equipment available for use with this machine are intended for general earth-
moving purposes, material rehandling, boring, ditch cleaning, etc. If the machine is to be used for handling
loads, (concrete pipe sections, shoring material, etc.), make sure the machine is suitably equipped for this type
of work. For this type of application, the machine must be equipped with safety valves, an overload indicator,
a load handling chart corresponding to the type of machine and its attachment and a load fixing point. All legal
requirements must also be strictly observed.
Do not use this machine for any application or purpose other than those described in this manual. If the
machine is to be used for work involving the use of special attachments, accessories or equipment, consult
your CASE Dealer in order to make sure that any adaptations or modifications made are in keeping with the
machine’s technical specifications and with prevailing safety requirements.
Any modification or adaptation which is not approved by the manufacturer may invalidate the machine’s initial
conformity with safety requirements.
The machine must undergo regular inspections, the frequency of which varies according to the type of use.
Consult your CASE Dealer.
Before permitting a new operator on this machine, make sure:
1. That the operator has received the necessary training on how to operate the machine correctly and safely
in one of our training centers or from an approved organization.
2. That the operator has read and understood the instructions given in this manual.
Always keep this manual in the operator’s compartment (in the seat back, behind the operator’s seat). Make
sure it is always complete and in good condition. If you wish to obtain additional manuals, or manuals in another
language, consult your CASE Dealer.
Your CASE Dealer is at your disposal for any further information. He will also provide any after-sales service
you may require, and genuine CASE spare parts, your guarantee of quality and match.

The illustration below shows the machine in normal TRAVEL position. In normal TRAVEL position, the cab is
over the idler wheels. The travel reduction gears are at the rear of the upperstructure.
Break-in
This product is shipped after full inspections and conditioning, however, extremely overloaded usage at the
initial stage could lead the reduction in performance and life. Therefore, approx. initial 100 hours (indicated
hours on the service meter) break-in is neccessary.
Break-in should be conducted paying attention to the following points:
• Try to keep idling and warming for 5 minutes after starting the engine.
• Avoid operation under heavy load or at high speeds.
• Avoid any sudden start, acceleration or unnecessary sudden stop and quick turn.

IMPORTANT:
Remove the protective (rust preventative) aluminum cover wrapped around the cylinder rods immedi-
ately after receiving the machine. If the machine is left with the covers on, water can collect on the
inside of the cover, which will be the cause for rust to develop on the cylinder rod.
In the case of transportation by sea, sea water salt adheres to the machine making rust easier to
develop. Immediately follow the measures below after receiving a machine that has been transported
by sea. If the measures are not taken, the machine will develop rust easily.
1. Confirm that there are no salt deposits on the
machine exterior. When salt deposits are sus-
pected, wash the entire machine with water.
2. Performing Rust Prevention Operation.
1Set the engine at low~medium rpm and go
through the warming up operation.
2Slowly operate each cylinder of the front attach-
ment five strokes each.
3. If Storage Is To Be Continued
[Storage procedures for rust prevention.]
1Grease up each part of the attachment.
(1) Once a week operate each motion (attachment,
swing, travel) with no load which performs rust
prevention operation.
1Put the engine in low~medium rpm and perform
the warming up operation.
2Slowly operate each cylinder of the front attach-
ment five strokes each.
(1) Place each cylinder in the most retracted posi-
tion and apply anti-rust oil to the exposed cylin-
der rod.
(2)
Perform rust-prevention operation once a month.
1Before performing the rust-prevention opera-
tion, remove the anti-rust oil (wipe off with kero-
sene, etc.).
2Afterfinishing therust prevention operation,fully
retract each cylinder and apply anti-rust oil to
the exposed cylinder rod.
CAUTION
Do not use high pressure cleaning water
directly on the alternator, battery and other
electrical parts or wiring.
CAUTION
Start the engine after you understand the oper-
ation methods.
