minutes.
2 Then increase engine speed to approx. 1,200
rpm.
3 Run out the bucket cylinder using the control
lever and let the bucket move to its end-position.
4 Then carry out a number of boom, dipper arm,
swing, and travel movements with the machine
to distribute the warmed hydraulic oil to all
hydraulic cylinders and motors.
Carry out these movements until the hydraulic
system has reached working temperature/rapid
working movements.

when loading onto or off a trailer) must be done
slowly with great care. Under these conditions the
engine speed must not exceed 1,200 rpm and the
travel speed control should be in low speed
position.
