The remote control system offers an excellent solution to
safety, speed and ease of use, less downtime, and overall
maneuverability. Like and device, there are precautions and
common sense that work hand in hand to assure safe and
reliable operations.
Never allow any operation until the operator has read all
instructions and has become completely familiar with the
total system. Should
anything happen unexplained,
unpredicted, or incorrect operation, immediately shut down
the complete system and investigate! This includes shutting
down all electronics, hydraulics, power take-offs, and
engines.
Never resume operation until the problem has been
corrected!
Danger Remote Start Hazard
The remote start relay has been intentionally supplied
separately from the rest of the remote engine compartment
wiring. Before installing the remote start relay on any
chassis, the installer must verify that the chassis can not be
started while the transmission is in gear. The remote start
relay is only to be installed on a chassis that is equipped with
a switch (neutral safety switch) that prevents the engine from
starting while the transmission is in gear. A chassis not
equipped with or that can not be equipped with a neutral
safety switch will not have the start relay installed and
therefore can not be started with the radio transmitter only.
Before attempting to start truck with remote control make
sure the drive train is in neutral.
When not using the remote control, disconnect power to the
remote control system with the selector switch installed in the
truck cab. This will prevent inadvertent operation of the crane
if the hand control is operated. Protect and monitor the hand
control unit to prevent damage and unplanned operation.

transmission to neutral.

position and start truck with the ignition switch in the
truck cab.
9. Set engine throttle control if not equipped with automatic
throttle advance.
10. Actuate desired crane function switch.
11. Slowly squeeze speed trigger to increase crane
operating speed.

RADIO REMOTE CONTROLS
Safety
The radio remote control system offers an excellent solution
to safety, speed and ease of use, less downtime, and overall
maneuverability. Like any device, there are precautions and
common sense that work hand in hand to assure safe and
reliable operations.
DANGER
Starting truck engine with drive train engaged will cause
unexpected movement of the truck resulting in death or
serious injury.
Do not install remote start relay on any chassis that can
be started while transmission is in gear.
Before a remote start relay can be installed, the chassis
must be equipped with a switch that prevents the engine
from starting while the transmission is in gear.
DANGER
Starting truck engine with drive train engaged will cause
death or serious injury.
Do not start truck engine unless drive train is in neutral.
