44 • Section 6 — Operation
DANGER
Death or serious injury will result from unprotected
contact with energized conductors. Maintain safe
clearance from electrical power lines and apparatus.
Allow for platform or line sway, rock, or sag.
Consult the load capacity chart to determine if reposition-
ing the vehicle or boom will allow the load to be lifted.
If the LMAP is inoperative or malfunctioning, the des-
ignated persons responsible for supervising the lifting
operations shall establish procedures to conduct the
lifting operation.
Use caution when lowering the boom. The unit’s capac-
ity and stability decrease as the boom is lowered. While
lowering the boom, refer to the load capacity chart and
use the personnel handling chart on the LMAP to make
sure that the load capacity of the unit is not exceeded.
Be aware of the stability limits of the particular unit. Read
and understand Section 4 under Capacity and Stability.
DANGER
Death or serious injury will result from unprotected
contact with energized conductors. Read and under-
stand the contents of Section 4 before operating the
unit near energized conductors.
Death or serious injury will result from contact with
or proximity to equipment that has become electri-
cally energized. Maintain safe clearances from all
energized conductors and any grounded device,
material, or equipment.
CAUTION
Injury and property damage can result from abrupt
reversals in direction, starts, or stops. Operate the
controls smoothly.
Avoid sudden starts, stops, or direction reversals of the
boom controls.
WARNING
Death or serious injury can result from two-blocking
the unit. The winch can break the load line if two-
blocked. Two-blocking may cause the load line to
fail and load/hook block to fall. Do not allow hook
block to contact boom tip by hoisting up, extending
or lowering boom.
Do not operate the winch function with the anti-two-block
switch disabled or the weight chain shortened. The weight
must be 30″ (76.20 cm) from the boom tip sheave.
Tilt Switch
The transmitter is equipped with a tilt switch that will
cause the transmitter to stop sending signals when it
is tilted more than 45 degrees in any direction for 4 to
5 seconds. The vehicle engine will continue to run, but
the unit’s functions will not respond to movement of the
transmitter controls.
To make the transmitter operational, return it to a level
position and reset it by performing the start-up procedure.
Sleep Mode
The transmitter is equipped with a sleep circuit that will
shut down the transmitter and vehicle engine automati-
cally. Shut down occurs when the engine rpm switch is
in the idle position and the transmitter is not used for
approximately 10 minutes.
To reset the transmitter after it has entered the sleep
mode, turn it off and perform the start-up procedure.
Battery Charger
The battery charger will restore the electrical charge
to the rechargeable transmitter batteries. The battery
charger automatically stops when the charging process
is complete. This allows the charged battery to be stored
safely in the charger until it is needed. A continuously on
charger LED indicate that the battery is charging. When
the charging is complete, the LED will ash.
Booms
The boom may be operated using the control panel or
the radio remote transmitter. When operating the boom
function, it may be necessary to use the foot throttle or
engine speed switch to increase engine speed.
When operating more than one boom function, it may be
necessary to use the foot throttle or engine speed switch
to operate the functions at full speed. Use only sufcient
foot throttle for maximum function speeds.
When starting and stopping any boom movement, me-
ter the hand control to avoid shock loads. This is very
important when handling heavy loads.
The lift cylinder is held in position at all angles by a pilot
operated counterbalance holding valve located in the
base end of the lift cylinder. This valve prevents loss of
oil from the cylinder if hydraulic line failure occurs, thus
preventing free fall of the booms. Due to the counterbal-
ance valve’s load holding capability, it is necessary to
power the booms down, rather than allowing them to
lower by gravity.
