OPTIONAL REMOTE CONTROL
OPERATION – WIRED
• The control functions operate the same
on a remote control machine as they do
on a swing-out machine. Instead of
having the machine mounted control
levers as described earlier in this section,
there are toggle switches on the machine
control box and on the remote control
unit. The toggle switches on the
machine control panel can be used to
operate the machine for short-term
operation to test the operation of the
functions.
• Use the switches on the remote
transmitter to operate the machine at the
job site. For a remote control machine
with a wired remote transmitter, turn the
Machine ON/Remote ON switch to
Remote On and turn the Engine switch
on the transmitter to RUN. Start the
engine using the key switch located on
the upper right hand side of the machine
control panel. Press and hold the
Murphy By-Pass while turning the key
switch. Run the engine a few minutes to
allow the oil to circulate before starting
to operate the functions. After the
engine has been running for a few
minutes, test the remote transmitter by
testing the functions for correct
operation. After testing the functions
and everything is operating correctly,
begin grinding the stump as described in
the Machine Operation section of this
manual.
• On a remote machine, the Swing Speed
Adjustment control is installed on the
side of the machine control box.
• Adjust swing speed for smooth
operation. Turn valve counter-clockwise
to slow cutter head swing as engine
speed increases. Close valve by turning
clockwise to allow head to move side to
side at low engine RPM.
