2.17 Shut-off operation
When not in use operator must lower boom and chassis. Furthermore, in winter, the hydraulic hoses on
the chassis and the piston rods must be cleaned so that dirt does not freeze on to them.
– Set back speed adjusting lever so that the engine is made to idle. Do not switch off engine from full
load but let it idle for three minutes to equalize the temperature. Shutting down from full load can
lead to turbo damage.
– Turn ignition key to position 0, engine shuts off. The engine can also be shut off with the Emergency
switch but must be unlocked before starting by turning, otherwise the engine can not be started.
Caution: During work breaks or when work ends, remove ignition key and make it inaccessible
to unauthorized persons.
2.18 Excavator operation
– As soon as the diesel engine has reached its operating temperature and is running at a speed
between 50 and 75% of the max. speed, start the operating or driving movements so that not only
the hydraulic tank but the whole hydraulic system is uniformly heated. In this way the machine will
quickly reach its full working performance. For excavating operation the diesel engine should run at
least 65% of the max. speed. According to the operating activity, the speed must be changed via the
speed adjusting lever.
– Slowing down the upper structure by reversing, i.e. switching on the opposite direction of rotation, is
not permissible.
– Never knock off slopes with the boom or dipper or fill in ditches from the side.
– Grade in boom direction only.
– In winter, the machine must be shut down on dry subsoil to prevent it freezing up.
– The excavator is designed for operating in terrain up to 100% in the line of dip and 70% diagonally to
the line of dip without terrain preparation.
– Only persons which are trained adequately and are authorized may operate the machine.
– The contractor is responsible for adapting safety instructions to local laws and condiditions, where
necessary.
– Before starting excavator operation the operator checks effectiveness of operating and safety
elements. During operation he monitors the correct function of the machine.
– Observed defects must be reported to the foreman or to the succeeding operator.
– In the event of trouble which endanger safety of machine operation must be stopped immediately.
