When the PWP System is active:
z transmission is de-clutched into Neutral,
z parking brake is applied,
z rear axle stabilizer cylinder is locked,
z frame leveling speed is reduced,
z auxiliary hydraulic and carriage tilt and swing
functions are disabled,
z machine inclination sensor is activated, with
the result that the Telescopic Handler must be
level laterally (side-to-side) and longitudinally
(front-to-back) to the factory pre-set limits before
the boom control joystick will function, and
z For 40’ and 44’ models, remote shutdown switch
is activated, meaning that the switch must be con-
nected and in the “on” position for the boom con-
trol joystick to function. Pressing the red button
will disengage the boom control joystick, and
stop all platform movement. The remote shut-
down switch box is supplied with a coiled electri-
cal cable, which must be connected to the outlet
on the front of the innermost boom section near
the carriage. The switch must be accessible to the
platform personnel at all times when the platform
is to be moved.
z For 55’ model, remote shutdown switch is acti-
vated, meaning that the switch must be “on” for
the boom control joystick to function. Pressing
the red button will disengage the boom control
joystick and stop all platform movement. The
remote shutdown switch box is a wireless remote
control, so there is no direct connection to the
Telescopic Handler. The switch must be accessi-
ble to the platform personnel at all times when the
platform is to be moved.
To de-activate the PWP system, apply the service
brakes and press the bottom of the PWP System rock-
er switch. The system is de-activated when the lamp in
the PWP System rocker switch is off.
NOTE: If the lamp in the PWP System rocker
switch is flashing, apply the service brakes until
the lamp goes off.
Stabilizer System
This is an additional safety function while elevating
loads for placement. At a pre-determined boom angle,
the stabilizer cylinder on the rear axle will lock up.
When this happens, the parking brake activates and the
frame leveling function slows down. Other than mov-
ing the boom and slowly leveling the frame, the
machine will not be able to move until the boom is
lowered below the pre-determined angle.
WARNING
The machine becomes less stable as the load
is raised higher.
NEVER use frame leveling to position an ele-
vated load. Always lower the load to the
ground and reposition the machine.
If a hydraulic boom circuit hose should break
with the boom up, shut down the machine. DO
NOT attempt to bring down the boom or make
repairs. Call your Gehl dealer immediately.
As lift height increases, depth perception
decreases. High elevation placement may
require a signal person to guide the operator.
DO NOT ram the lift cylinders to the end of the
stroke. The resulting jolt could spill the load.
The truss boom attachment tool should ONLY
be used to lift and place loads when the
machine is in a stationary position. DO NOT
use to transport loads around the jobsite. This
can cause the load to swing, resulting in either
the load dropping or machine tipping over.
WARNING
In an emergency, if the platform worker has
activated the remote shut-off switch and then
is not able to re-activate the switch, such as if
the worker fainted, then the Telescopic
Handler operator is permitted to turn off the
PWP System to regain control of the boom
functions, in order to lower the work platform
and come to the aid of the worker. But, under-
stand this is only
permitted in case of an
emergency. Otherwise, the PWP System must
be used at all times when there are workers on
the platform. This is the only exception!
