Accumulator Charged

If electrical power is available and the accumulator

is charged, the loader arms can be lowered from the

operator station with the work tool control.

1. Fasten the seat belt. Lower the armrests.

2. Move the engine start switch to the ON position.

NOTICE

If long term storage for a period of time exceeding one

year is necessary, contact your local Caterpillar deal-

er for the preferred procedure to use in your specific

case.

This machine may be stored for one year or less in

a temperature range of -32 °C (-25.6 °F) to 43 °C

(109.4 °F).

To store machines in ambient temperatures between

-20 °C (-4.0 °F) to 43 °C (109.4 °F), refer to Special

Instructions, SEHS9031, “Storage Procedure for

Caterpillar Products”.

To store machines in ambient temperatures between

-32 °C (-26 °F) and -21 °C (-6 °F), refer to the

following publications and topics:

• Special Instructions, SEHS9031, “Storage

Procedure For Caterpillar Products”

• Operation and Maintenance Manual, SEBU5898,

“Cold Weather Recommendations for Caterpillar

Machines”

Note: Do not use the steps that are listed in Special

Instructions, SEHS9031 in order to maintain the fuel

system.

Use the following steps to maintain the fuel system.

1. Drain the fuel tank. Follow the procedure that is

described in Operation and Maintenance Manual,

“Fuel Tank Water and Sediment - Drain”.

2. Drain the water separator and replace the

element. Follow the procedure that is described

in Operation and Maintenance Manual, “Fuel

System Water Separator Element - Replace”.

3. Fill the fuel tank so that the fuel tank is at least

20% full with Calibration Fluid.

4. Prime the fuel system. Follow the procedure that is

described in Operation and Maintenance Manual,

“Fuel System Prime”.

5. Start the engine and run at low idle for

approximately 15 minutes in order to allow the

calibration fluid to flush the diesel fuel from the

system.

6. Turn off the engine.

Machine Retrieval

SMCS Code: 7000

If the machine is disabled, the machine should be

lifted onto a trailer in order to be transported. Refer

to Operation and Maintenance Manual, “Lifting and

If the machine cannot be lifted, use the following

guidelines in order to retrieve the machine.

Illustration 91

Two towing eyes (2) are located on the rear of the machine.

• The strength of the line should be at least 1.5 times

the gross weight of the machine.

• Provide shielding in order to protect the operator

if the line breaks.

• If a single line is used to pull the machine, then the

line must be a minimum of 3 m (10 ft). If two lines

are used to pull the machine, then each line must

be a minimum of 1.5 m (5.0 ft).

• Do not exceed a maximum pull angle of 20 degrees

in any direction.

Cat HYDO Advanced fluids have a 50% increase

in the standard oil drain interval for machine

over second and third choice oils when you follow the

maintenance interval schedule for oil filter changes

and for oil sampling that is stated in the Operation

and Maintenance Manual for your particular machine.

6000 hour oil drain intervals are possible when using
