OPERATING INSTRUCTIONS
BRINGING THE MACHINE UP TO OPERATING
TEMPERATURE
IMPORTANT: Normal operating temperature of the hydraulic fluid is between
50° C and 80° C (122-176F), in the middle of the temperature indicator. If the
machine is used with the hydraulic fluid at a temperature below 20° C (68F), then
damage can be caused.
After starting the engine and before using the machine, allow the hydraulic fluid to
reach a temperature of 20° C(68F), as indicated by the appearance of the first bar
segment on the hydraulic fluid temperature indicator. See item 8 under “Systems
display and control panel” in the “Controls/Instruments/Accessories” Section.
Idle - Start
At start-up the engine speed defaults to low idle regardless of throttle position.
This prevents over speeding a cold engine and extends its service life.
Auto engine warm-up
TRIM THIS EDGE
Once the engine has started, the warming-up process begins automatically. At
first, engine speed is held at a pre-determined, low level. As the temperature
increases, engine speed increases in proportion. It is possible to interrupt the
warming-up process at any time, simply by manually changing engine speed or by
operating one of the control levers. Warming-up takes approximately 5 to 10
minutes.
Engine manual warm-up
With the engine throttle button a quarter open, start the engine and allow it to run
approximately for 5 to 10 minutes. When the coolant temperature increases, carry
out the hydraulic fluid warm-up procedure.

OPERATING ON SLOPING GROUND
WARNING: Hillside operations can be dangerous. Rain, snow, ice, loose
gravel, soft ground, etc... modify terrain conditions. It is up to you to decide
! if the machine can be used in perfect safety.
● During hillside operations, be extra careful.
● Make sure the upper structure swing is in locked position and that low travel
speed is selected.
● When digging on a slope, avoid swinging the upper structure towards the
bottom of the slope with the bucket full. Always keep the travel reduction gears
pointing down towards the bottom of the slope.
● Always travel in the same direction as the slope, to prevent the machine from
turning over.
