OPERA
TION
To relieve the pressure, move the Tool Selector to the
“OFF” position. Connect the hydraulic tool hoses to
the tool ports (quick-disconnect outlets). Activate
operating pressure to the hydraulic tools by moving
the Tool Selector to the “ON” position.
WARNING
: FAILURE TO RELIEVE
PRESSURE TO THE TOOL PORTS BEFORE
CONNECTING OR DISCONNECTING THE
HYDRAULIC TOOL HOSES MAY RESULT IN A
HIGH PRESSURE HYDRAULIC OIL SPRAY. THIS
SPRAY OR MIST CAN PUNCTURE AND BECOME
EMBEDDED BENEATH THE SKIN OR
CONTAMINATE THE EYES. THESE CONDITIONS
REQUIRE IMMEDIATE MEDICAL ATTENTION.
HYDRAULIC PLATFORM ROTATOR (Standard with
Single Stick Control)
- The platform mount allows
the platform to rotate 180 o from one side of the outer/
inner boom assembly, across the end hung position,
to the other side of the outer/inner boom assembly.
To rotate, place the handle in the clockwise or counter-
clockwise (“CW” or “CCW”) position.
TWO-SPEED MANUAL THROTTLE CONTROL
(Standard)
- The two-speed manual throttle control
is operated by an air cylinder plunger knob at the
upper controls. The two-speed control is designed to
operate only if the engine is running and the master
control is activated.
To speed up the engine from the upper controls
push the plunger knob down once and release it.
To slow the engine to an idle from the upper
controls
push the plunger knob down and release it.
It is recommended that the engine be left at idle until
faster lift movements are required. This practice will
provide efficient operation and minimize fuel
consumption. During hydraulic tool operation the oil
flow will be adequate to operate the tools at idle speed.
BACKUP PUMP CONTROL (Option) - The backup
pump system is operated by an air cylinder plunger
knob. The backup pump system should not be
operated longer than 30 seconds continuously.
Continuous use will drain the battery and damage (over
heat) the backup pump motor.
To activate this system from the upper controls,
push the air cylinder plunger knob down and hold it
while operating the lift controls.
To turn off the backup pump from the upper
controls,
release the air cylinder knob and allow it
to return to the neutral position.
STORING THE AERIAL LIFT
When storing the aerial lift for road travel retract the
inner boom completely. Rotate the outer/inner boom
assembly until it is centered over the boom rest.
Rotate the platform so the bottom of the platform is
centered over the platform support. Always stow the
lower boom before descending the outer/inner boom
assembly onto the boom rest. Release the outer/
inner boom control lever as soon as there is firm
contact with the boom rest pad. The platform will
