RD12A/12K Operation

6.13 Using the Forward/Reverse Lever

Background

Both roller drums are driven. An infinitely variable displacement pump drives the

hydraulic motors fitted to each drum. The machine moves forward or in reverse by

using the forward/reverse lever located to the side of the operator’s seat.

Travel

direction

Move the forward/reverse lever into FORWARD (f) or REVERSE (r) according to

the direction of travel desired.

To change direction of travel from FORWARD to REVERSE or vice versa:

1. Move the forward/reverse lever to the “N” NEUTRAL position (n).

2. Allow the machine to come to a complete stop.

3. Move the forward/reverse lever in the direction desired.

Note: In order to comply with safety standards, the machine has a device which

only enables starting of the engine when the forward/reverse lever is in the neutral

position.

Travel speed

■ Travel speed varies from “ZERO” to a permitted maximum of 8 kph (5 mph).

■ The farther forward or reverse the forward/reverse lever is positioned, the faster

the roller will travel.

■ Travel speed is the same in both FORWARD and REVERSE.

Note: When negotiating slopes, keep the forward/reverse lever at minimum travel

speed.

Braking

The forward/reverse lever can be used as an engine brake. Shifting the forward/

reverse lever to the neutral position stops the machine.

Operator

presence

system

The machine is equipped with an operator presence system. The system prevents

the machine from moving forward or in reverse unless the operator is seated. The

operator should remain seated at all times.
