5. Tilt Alarm Warning Light - A warning light on the
control console that lights when the chassis is on a
severe slope (over 3 °).
NOTE: The lift toggle switch automatically returns to the
center off position when released.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF LIFT
TOGGLE SWITCH DOES NOT RETURN TO THE CENTER OFF
POSITION WHEN RELEASED.
6. Lift Switch - The lift toggle switch provides for rais-
ing and lowering the platform when positioned to up
or down.
7. Engine Speed Switch - A two position engine
speed control switch provides the operator either
high or low engine rpm as required.
8. Pump Speed Switch - A two position pump speed
control switch allows the operator to select low (one
pump section operating) or high (both pump sec-
tions operating) speed pump operation.
NOTE: HIGH ENGINE speed, high drive speed (SPEED),
and HIGH PUMP speed functions will cut-out when
platform is raised above stowed position, leaving
only low function speeds available until platform is
lowered completely.
DO NOT OPERATE MACHINE IF HIGH DRIVE SPEED, HIGH
ENGINE SPEED, AND HIGH PUMP SPEED FUNCTIONS OPERATE
WHEN PLATFORM IS RAISED ABOVE THE STOWED POSITION.
9. PQ Controller - The PQ Controller performs three
functions: Drive, Steer and Drive Speed. On all
machines built before serial number 0200058922,
tilting the controller in the direction you want to go
(forward or reverse) activates drive in that direction.
The thumb-operated steer switch on top of the con-
troller handle activates the steer wheels in the direc-
tion it is moved. If machine is equipped with four
wheel steer, this switch operates only the front steer
wheels. On all machines built after, and including,
serial number 0200058922 there is a red trigger
switch on the front of the controller. This switch must
be depressed and held in order to drive the
machine.

connected to a sensor on the engine that detects
when oil pressure falls below a preset level, illumi-
nating the warning light.
