WARMING UP THE MACHINE

(HYDRAULIC OIL)

Operating the working equipment without

warming up the machine (hydraulic oil) is

dangerous, as the working equipment

cannot response to controls quickly or

may move in unexpected ways, and the

safety devices may not operate properly.

Be sure to sufficiently warm up the

disengage the lock and lift the bucket from

the ground.

IMPORTANT: Do not operate the levers

too quickly when the hydraulic oil

temperature is below 20°C (68°F). The

proper hydraulic oil temperature during

operation is 50 to 80°C (122 to 176°F). If

operations must be performed at lower

temperatures, heat up the hydraulic oil to

at least 20°C (68°F).

INSPECTION AFTER WARM-UP

After warming up the engine and machine

(hydraulic oil), perform the checks and

inspections described below, and repair if

necessary.

5. Travel slowly forward and in reverse

several times.

Warm-up in cold climates

1. Perform the normal warm-up procedure.

1. Check that the warning lamps and meters

are as follows:

· Are all warning lamps off?

· Is the LED on water temperature gauge

seen within the green range?

2. Check that there are no irregularities in the

exhaust color, sound and vibrations.

2. Set the bucket cylinder at the stroke end

and keep it there.

Do not keep this condition for more than

30 seconds.

3. Repeat Step 2 until the bucket operating

speed becomes normal.

3. Raise the safety lock lever to the locked

position, and then check that the

operating and travel levers are locked.

CRAWLER WIDTH SWITCHING

Operate the machine with the maximum

crawler width

• Always operate the machine with the

crawler width extended to 1300 mm

(51.2 in.) to maximize the machine

stability. If the machine is operated with

the crawler width narrowed (980 mm,

38.6 in.), the machine may tip over due

to its poor stability.

• If the machine must be operated with

the narrowed crawler width (980 mm,

38.6 in.), traveling should be done after

folding the hoe attachment, lowering the

boom to lower the center of gravity and

keeping the machine facing forward.

This machine is able to change the crawler

width. Normally, it is best to operate with the

crawler width extended for machine’s

stability.

you must park on a slope, chock the

tracks to block the machine.

• If any control is accidentally touched

when the safety lock lever is not locked,

the machine may suddenly move and

cause serious injury or death.

• Note that the dozer blade, boom swing

and auxiliary hydraulic controls cannot

be locked, even when the safety lock

lever is set to the locked position.

Do not carelessly touch these controls.

Never stop running the machine suddenly
