Enable Switch - The machine is equipped with an
ENABLE switch, located on the left side of the plat-
form control box. On all machines with a serial num-
ber before 0200058990 the ENABLE switch must be
depressed before activating the DRIVE or LIFT func-
tions. A built-in timer shuts off power to these func-
tions if they are not activated within three seconds
after the ENABLE switch is depressed. In addition,
this timer will shut off power to these functions three
seconds after they are deactivated, making it neces-
sary to depress the ENABLE switch before activating
DRIVE or LIFT again.On machines built from, and
including, serial number 0200058990 the ENABLE
switch must be depressed and held for the duration
of lift. The ENABLE switch works in conjunction with
the lift switch only.
3.
Emergency Stop Switch - A two-position, red, mush-
room-shaped EMERGENCY STOP switch functions
to provide power to the platform control station and
also to turn off power to the platform function con-
trols in the event of an emergency. With the POWER
SELECTOR switch positioned to PLATFORM, power
is turned on by pulling the switch out (ON), and is
turned off by pushing the switch in (OFF).
4.
PQ Controller - The PQ Controller controls three
functions: DRIVE, STEER and DRIVE SPEED. On all
machines, built before serial number 0200058990,
tilting the controller in the desired direction of travel
(forward or reverse) activates drive in that direction.
DRIVE SPEED is controlled by the distance the con-
troller is moved from the center-off position. The
thumb-operated STEER switch on top of the control-
ler handle activates the steer wheels in the direction
it is moved (right or left). On all machines built after,
and including, serial number 0200058990 there is a
red trigger switch on the front of the PQ Controller.
This switch must be depressed and held in order to
drive the machine
5.
Engine Speed Switch - The two position ENGINE
SPEED switch permits the operator to select either
HIGH or LOW engine rpm as required.
DO NOT USE HIGH ENGINE SPEED WHEN DRIVING IN CLOSE
QUARTERS OR WHEN DRIVING IN REVERSE.
