OPERATING PROCEDURE
Lowering The Work Equipment With Engine Stopped
If the engine stops, the work equipment (boom/bucket,
attachments) can be lowered to the ground using
hydraulic pressure which is stored in the accumulator.
The console must be in the locked down position, and the
key switch in the ON position.
Use the control lever to lower the boom.
Operating On Public Roads
When operating on a public road or motorway, always
follow local regulations. For example: A slow moving
vehicle (SMV) sign, or direction signals may be required.
Check with services companies for underground
electrical, water, gas lines, etc. work slowly in areas of
underground powerlines.
Lifting A Load
Do not exceed the rated lift capacity. See Lift Capacity on
Page 101 and 109.
WARNING
AVOID INJURY OR DEATH
Do not exceed Rated Lift Capacity. Excessive load
can cause tipping or loss of control.
W-2476-1003
Extend the bucket cylinder completely and lower the
boom to the ground. Stop the engine.
Wrap the chain assembly around the bucket mounting
plate.
Figure OI-96
Make sure the load is evenly weighted and centred on the
lifting chain, and is secured to prevent the load from
shifting [Figure OI-96].
Lift and position the load. When the load is in position and
tension is removed from the lift chain (secondary lift
system), remove the secondary lift system.
Figure OI-97
The optional lifting clamp attachment gives the excavator
a wider range of use and mobility for debris removal
[Figure OI-97].
The lifting clamp cylinder is operated by the auxiliary
hydraulic system.
The lifting clamp cylinder must be fully retracted when the
machine is being used for excavating.
The lift capacities are reduced by 122 kg if the excavator
is equipped with the optional lifting clamp.
