RD 16 Operation
wc_tx001075gb.fm 53
3.23 Transmission
See Graphic: wc_gr002954
Both roller drums are fitted with hydraulic motors which are driven by
an infinitely variable displacement pump and hydrostatic transmission.
Forward and reverse travel are selected using a forward/reverse
control (15) located next to the driver’s seat. In order to comply with
safety standards, the machine has a device which only enables
starting of the engine when the forward/reverse control is in the
NEUTRAL position.
Forward/reverse control
Shift the forward/reverse control (15) into FORWARD (F) or REVERSE
(R) according to the direction of travel desired. The further forward or
reverse the control is positioned, the faster the roller will travel.
Road speed is the same in both FORWARD and REVERSE. If you
wish to change direction of travel from FORWARD to REVERSE or
vice versa, move the control to the NEUTRAL position (N), allow the
vehicle to come to a complete stop, then move the control in the
direction desired.
During operation run the machine at high throttle. Quickly press and
release the upper half of the throttle switch (54) to bring the engine to
high throttle.
When negotiating gentle slopes, keep the engine at high throttle and
the forward/reverse control at the minimum speed position.
NOTICE: This vehicle has a hydrostatic transmission which means
that the forward/reverse control can also be used as an engine brake.
Shifting the control to the NEUTRAL position stops the machine travel.
NOTICE: Never drive the machine at low idle speed. Driving the
machine at low idle speed can damage the drive pump.
