5.17 Towing Bypass Valve
See Graphic: wc_gr002960
The drive circuit is equipped with a towing valve
(43)
to allow oil to
bypass the drive motors and let the roller freewheel for towing.
The towing valve should be used in emergency cases where the
machine has become bogged down in loose or muddy soil, or cannot
be driven due to an engine or hydraulic system failure.
With the towing valve open, the drive circuit has no braking action and
the machine will roll freely. Apply the brake or attach the towing device
before opening the towing valve. Close the towing valve immediately
after the towing operation is complete to prevent the machine from
rolling unexpectedly.
To open the bypass, shut the engine off and rotate the shaft on the
towing valve counter-clockwise.
When resuming machine operation, make sure the bypass is closed by
rotating the shaft on the towing valve clockwise.
