4.13 Using the Forward/Reverse Lever
Background Both roller drums are driven. An infinitely variable displacement pump and
hydrostatic transmission drive the hydraulic motors fitted to each drum. The
machine moves forward or reverse by using the forward/reverse lever located to
the side of the driver’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 10 kph (6.2 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
present
system
The machine is equipped with an operator present system. The system prevents
the machine from moving forward or reverse unless the operator is seated. The
operator should remain seated at all times.
