vice brakes on for three or more seconds, and press the
top of the PWP rocker switch. The system is activated
when the lamp in the PWP rocker switch is on conti-
nously.
NOTE:
If the light is flashing, apply the service
brakes until the light stops flashing.
When the PWP System is active:
l
transmission is de-clutched into Neutral
l
parking brake is applied
l
rear axle stabilizer cylinder is locked
l
auxiliary hydraulic and carriage tilt and swing
functions are disabled
l
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 within the factory preset limits
before the boom control joystick will function
l
For 42-foot and 44-foot models, the remote shut-
down switch is activated, with the result that the
switch must be connected and in the “on” position
for the boom control joystick to function.
Depressing the switch will disengage the boom
control joystick, and stop all platform movement.
The remote shutdown switch box is supplied with
a coiled electrical cable that must be connected to
the outlet on the front of the innermost boom sec-
tion near the carriage. The switch must be acces-
sible by the platform personnel any time the plat-
form is to be moved.
l
For 55-foot model, remote shutdown switch is
activated, 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
accessible to the platform personnel at all times
when the platform is to be moved.
To de-activate the system, apply and hold the service
brakes on for three or more seconds, and press the bot-
tom of the PWP System rocker 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 angle, the
stabilizer cylinder on the rear axle will lock up. When
this happens, the parking brake is activated. The
machine will not be able to move until the boom is
lowered below the pre-determined angle.
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!
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 Manitou Americas 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.
WARNING
ALWAYS check the PWP System for proper
operation prior to use. (See page 61 for PWP
System checking procedure.)
