3. PLATFORM UP PAD SWITCH (Up Arrow)
When pressed in conjunction with the lift enable pad
this switch raises the platform to a higher level, when
released the upward movement is stopped.
4. PLATFORM DOWN PAD SWITCH (Down Arrow)
When pressed in conjunction with the lift enable pad
this switch lowers the platform from a raised posi-
tion, when released, the downward movement is
stopped.
5. EMERGENCY STOP/SHUT-OFF BUTTON
An EMERGENCY STOP (RED) button is provided in
order to immediately stop machine functions from
the platform in the event of an emergency. When
button is depressed, all machine functions will stop.
To re-activate power to the machine, turn button
clockwise to RESET the emergency stop.
6. JOYSTICK DRIVE/STEER CONTROL and DRIVE
ENABLE BUTTON
This is a “Point & Go™” control which moves the
machine in the direction which the stick is moved. It
is a fully proportional control, the further from the
center position the joystick is moved, the faster the
machine travels. To activate the control depress and
HOLD the DRIVE ENABLE BUTTON on the top of
the joystick, then move the joystick in the direction
of travel desired.
7. VARIABLE SPEED CONTROL
The variable speed control knob can be used to
increase or decrease the maximum drive speed of
the machine. Clockwise rotation of the knob
increases speed, counterclockwise decreases
speed.
When the platform is elevated drive speed is auto-
matically cut to one fourth of when the platform was
in the lowered position.
8. WARNING HORN SWITCH
If machine is equipped with (optional) mounted
horn, this switch when pressed sounds the horn.
Brake Release Control
(See Figure 3-3.)
Standard equipment on all VPSP model lifts is a braking
system integrated into the electric motor drive system.
The braking system is spring engaged and released elec-
trically while the machine is being driven with the joystick
controller. When the lift is at rest or the power is turned off,
the brakes are automatically engaged.
If the lift must be moved around manually such as
described in the following examples; the batteries
become depleted and the machine needs to be moved
from an aisleway, or machine is being winched onto a roll-
back truck bed, etc, the brakes can be manually disen-
gaged. To release the brakes, a brake release control has
been provided to engage/disengage the brake system.
AFTER THE MACHINE HAS BEEN MANUALLY MOVED AND
BEFORE DRIVING MACHINE, ALWAYS RE-ENGAGE THE BRAKE
SYSTEM.
IMPORTANT
WHEN PUSHED OR PULLED MANUA LLY, TH E MACHINE ‘S
BRAKES MUST BE DISENGAGED AND THE EMERGENCY STOP
BUTTON SET TO THE OFF POSITION, (DEPRESSED) AND THE
KEY SWITCH SET TO THE OFF POSITION. DO NOT ATTEMPT TO
TOW OR WINCH THE MACHINE AT A SPEED GREATER THAN (2)
MPH, OR DAMAGE COULD OCCUR TO THE MACHINE‘S ELEC-
TRONIC CONTROLLER BOX - (DUE TO HIGH VOLTAGE BEING
GENERATED BY THE DRIVE MOTORS FEEDING BACK INTO THE
CONTROLLER BOX).
The brake release control lever is located on the right side
of the mast. To disengage or engage the brakes, check
the brake decal located just above the handle assembly to
see which direction the handle needs to be pointed. The
brakes are ENGAGED (normal driving position) when the
handle is in the up (vertical) position. The brakes are DIS-
ENGAGED when the handle is pulled down in a horizontal
position, (machine can be moved manually when the han-
dle is pulled down in a horizontal position).
