SP4012 MACHINE CONTROLS
16
OPTIONAL REMOTE CONTROL
OPERATION – WIRED
• The control functions operate the same
on a remote control machine as they do
on a standard 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 position the machine or to
test the operation of the functions.
• Use the switches on the remote
transmitter to operate the machine when
moving the machine to the job site and
when grinding the stumps. 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. Now start the
engine using 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, proceed to the job
site.
• Some functions require using the
machine mounted controls, such as the
Swing Speed Adjustment Valve, the
Ground Speed Adjustment Valve, the
Freewheel Valve on machines equipped
with freewheel motion, and the
Engagement Lever to engage the cutter
wheel. The Swing Speed Adjustment,
Freewheel, and Ground Speed
Adjustment Valves are on opposite sides
of the machine from the standard
machine but still operate the same.
