The roller may be moved up to 50 m as follows:
Stop the engine. Disc brakes applied.
Turn the arm (2) on the bypass valve (1) 90° to disen-
gage the hydrostatic brake.
Chock the drums before doing any work
underneath the roller.
Pull out the reserve brake knob to release the disc
brakes.
Start the engine and tow the roller.
The roller must always be counter-braked
when towing downhill; always use a towbar
because the roller will have no ability to
brake.
Restore the bypass valve after towing.
