OPERA
TION
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, Figure 4.2.
CONTROL SELECTOR AND OUTRIGGER/BOOM
INTERLOCK
- The outrigger/boom interlock is a
feature designed to prevent the lift from being
operated until the outriggers are properly extended.
The interlock also prevents the outriggers from being
retracted before the lift is properly stored. This option
is particularly useful in keeping unauthorized personnel
from operating the outriggers while an operator is
working aloft.
