Snorkel AB50JRT - Manual (Page 68)

■ Driving the AB50J
The AB50J chassis can only be driven from the
platform control box. You cannot drive from the
ground control box.
There is a blue arrow on the forward end of the
chassis and a yellow arrow on the reverse end of
the chassis.
❑ Forward and Reverse Drive
Pushing the Drive/Steer controller to FORWARD
causes the chassis to move in the direction of the
blue arrow on the end of the chassis.
Pushing the Drive/Steer controller to REVERSE
causes the chassis to move in the direction of the
yellow arrow on the opposite end of the chassis.
You must be stepping on the platform foot
switch for the Drive/Steer controller to work.
■ Steering the AB50J
The AB50J can only be steered from the platform
control box. You cannot steer the AB50J from the
ground control box.
There are two blue arrows on the left side of the
chassis and two yellow arrows on the right side of
the chassis.
❑ Steer Left and Right
Pushing the Drive/Steer controller to LEFT
causes the front wheels to turn for a left turn.
Pushing the Drive/Steer controller to RIGHT
causes the front wheels to turn for a right turn.
You must be stepping on the platform foot
switch for the Drive/Steer controller to work.
When you release the Drive/Steer controller
the wheels stay where you set them. The
wheels do not return to the “straight ahead”
position the way automobile wheels do.
❑ 4-Wheel Steer
An AB50J equipped with optional 4-wheel steer
can make extremely sharp turns by turning the
two front wheels (1) one direction then turning
the two rear wheels (2) the opposite direction.
4-wheel steer works like 2-wheel steer: Hold the
Drive/Steer controller to the RIGHT or LEFT until
the front wheels (1) turn as far as they will go.
Continue to hold the Drive/Steer controller to the
RIGHT or LEFT and the rear wheels (2) will begin
to turn.
