OPERA
TION
MOISTURE IN THE BOOM WHICH MAY
DEGRADES THE INSULATION. THIS MAY
RESULT IN DEATH OR SERIOUS INJURY IN EVENT
OF AN ELECTRIC SHOCK.
DANGER:
EQUIPMENT WHICH
BRIDGES BETWEEN THE PLATFORM AND
GROUND RENDERS THE INSULATION USELESS
AND MAY RESULT IN DEATH OR SERIOUS
INJURY IN THE EVENT OF AN ELECTRIC SHOCK.
DANGER:
GIVE WARNING AND
NEVER ALLOW ANYONE ON THE GROUND TO
TOUCH THE UNIT WHEN THE LIFT IS BEING USED
TO WORK ON OR NEAR ELECTRICAL LINES. IF
THE UNIT BECOMES ENERGIZED DEATH OR
SERIOUS INJURY WILL RESULT FROM CONTACT
WITH THE UNIT.
DANGER:
CONTACT BETWEEN AN
ELECTRICALLY CHARGED WIRE AND A METAL
PART OF THE BOOM MAY CAUSE THE WIRE TO
BURN THROUGH, LETTING THE TWO WIRE ENDS
FALL TOWARD THE GROUND. THIS WILL CAUSE
DEATH OR SERIOUS INJURY TO INDIVIDUALS ON
THE GROUND.
As stated previously, it is the responsibility of the
operator and the ground crew to know and understand
the capabilities and limitations of the aerial lift and
hazards associated with operation near electric lines
or components. In addition they must apply this
knowledge to situations that arise on the job for safe
and efficient operation.
CAB CONTROL OPERATION
The cab controls include the master control, the engine
start/stop control, and the PTO shifter.
MASTER CONTROL (Standard) - The master control
consists of a toggle switch and a light mounted on
the dashboard of the truck. The toggle switch is used
to energize or de-energize the start/stop system and
the throttle control options. When the light is on the
toggle switch is energizing these systems.
ENGINE START/STOP (Standard) - The engine start/
stop is a push button control that is usually mounted
on the dashboard of the truck. The system is activated
by pushing and holding the button momentarily to
“start” the engine. If the engine does not crank then
the start/stop button may require a second push to
get the latching relay into the “start” position so the
truck engine will turn over. Then to turn the engine off
press the start/stop button again. This feature is
especially convenient when the lift is being operated
from the lower (turret) controls.
DANGER:
THE TRUCK TRANSMISSION
MUST BE IN NEUTRAL OR PARK BEFORE USING
THE ENGINE START/STOP. STARTING THE
ENGINE WITH THE TRUCK IN GEAR WILL CAUSE
MOVEMENT WHICH MAY CAUSE DEATH OR
SERIOUS INJURY TO THE OPERATOR OR
ANYONE IN THE PATH OF THE TRUCK.
POWER-TAKE-OFF(PTO) (If So Equipped.) - The
power-take-off is a gearbox used to transmit power
from the truck transmission to the hydraulic pump,
providing hydraulic oil for the aerial lift functions. The
PTO control consists of a toggle switch and a red
light mounted in the truck dashboard. When the red
(PTO) indicator is lighted the PTO is activated. The
operator must never drive the truck with the PTO
engaged.
CAUTION:
DRIVING WITH THE PTO
ENGAGED MAY DAMAGE THE TRANSMISSION,
PUMP, AND/OR THE PTO.
To engage the PTO properly refer to the operating
instructions located in the PTO manufacturer’s owner
manual. If the PTO control is not responding properly
or if the manufacturer’s operating decals are not
posted in the cab (near the control) notify the
appropriate personnel for correction.
GROUND CONTROL OPERATION
The Versalift ground controls may include one or more
of the following controls: outrigger, outrigger/boom
interlock, and tool power. Ground controls are usually
mounted on panels in the rear bumper of the truck or
below the deck. Descriptions and operating
procedures for these controls are given in the following
text.
OUTRIGGER OPERATION - The outriggers (if so
equipped) should always be extended to provide
stability for the aerial lift. The outrigger controls consist
of a control selector and a control valve as shown in
Figure 4.2.
