Operating instructions
WARNING
Misuse hazard!
Follow the operating instructions in this chapter. Any other practice that has not received the prior
approval of the manufacturer is considered to be strictly forbidden.
Failure to comply could result in death or serious injury.
Watch carefully and make sure you are aware of places
where other people are working in your work area. Keep
all other people away from the machine. Serious injury
can result if these instructions are not followed.
Take note of the locations of pipes/cables before starting
work. Electrical cables, gas and water pipes and other
underground installations can cause serious injury.
Modify your driving to suit working conditions (sloping or
rough ground), the nature of the ground and weather con-
ditions.
On steeply sloping ground, keep engine at maximum
speed.
When travelling at right angles to the slope, move on to
the slope at low speed. Never reduce engine speed when
travelling down slopes.
Holes, obstacles, debris and other danger risks in the
working area can cause serious injury. Inspect and note
all possible risks before driving the machine in a new
working area.
Do not work near overhead high-voltage electric lines
without checking beforehand that all necessary measures
have been taken to respect the minimum distances:
Less than 57 000 volts: 3 m (9.8 ft).
More than 57 000 volts: 5 m (16.4 ft).
Never hit or push material with the sides of the bucket.
Never sweep the ground with the bucket to level rubble.
When operating the control levers, a whistling sound will
be heard if the control lever is held in position while the
corresponding cylinder is at the end of its stroke. In this
case release the control lever.
If earth or mud stays stuck inside the bucket, open and
close the bucket several times so as to loosen the earth
or the mud.
After work, remove any mud and clean the machine.
When operating the attachment, take care that the bucket
does not hit the dozer blade (if equipped).
Take care not to hit the dozer blade (if equipped) against
rocks.
4 - OPERATING INSTRUCTIONS
When using the upperstructure swing, never change the
direction of swing too suddenly.
If the operation of the dozer blade (if equipped) is not
necessary, always make sure that it is in maximum raised
position.
During filling in operations, operate the two travel levers
with your left hand while operating the dozer blade control
lever (if equipped) with your right hand.
When climbing up a slope, place the bucket about 40 cm
(15.7 in) above the ground. When travelling down a slope
it is recommended to place the bucket on the ground to
prevent the machine from sliding.
Avoid turning the machine on steep slopes.
Never swing the upperstructure on slopes of 15 ° in the
direction of travel or 10 ° at right angles to the direction of
travel.
The following operations are likely to damage the
machine. You are therefore advised to avoid them:
• Excavation using the weight of the machine as a force
of impact.
• Excavation using the machine's travel force.
Operation
ATTENTION: Do not operate the engine with the machine
at 35 °. The engine or hydraulic devices may be dam-
aged.
The maximum slope climbing ability is 35 ° 70 %. This
value varies depending on the track type and the road
surface, limit travelling to slopes of 30 ° or less.
1. Sit in the operator's seat and adjust it so that all the
controls are readily accessible then fasten your safety
belt.
2. Make sure the cab door is firmly latched in the open
or closed position.
3. Sound the horn.
4. Start the engine, taking into consideration the prevail-
ing weather conditions.
5. Check all indicator lamps and gauges are operating
correctly.
6. Lower the function cancellation lever.
