OPERATING INSTRUCTIONS RH170 Operation

Positioning of the machines

The auxiliary machine is driven close to the RH170B from behind (Fig. 2-100:).

Loosen the high-pressure lines (1, 2, 3 and 4, Fig. 2-101) and close the open ends of the hoses.

 Connect the hoses from the auxiliary machine to the ports of the "travel hydraulics" of the excavator.

 High-pressure hoses (1 and 2) - circuit 1 on auxiliary machine

 High-pressure hoses (3 and 4) - circuit 2 on auxiliary machine

Do not allow pressure in control line to rise above 30 bars / 435psi as this will shift the track gears into their “fast” ranges.

Emergency travel

 Start up the engine of the auxiliary machine. The brakes of the RH170B are released by travel pressure.

 Initiate the travelling movements carefully with the control levers. Adjust the direction and travelling speed of both tracks accordingly.

 Shift the control lever to the final position. Make sure the auxiliary machine is able to "follow"

The RH170B can be steered as usual by releasing the one or the other control lever briefly. Drive the excavator out of the hazard zone only.
