Operating Procedures 5
Sander Control Box
The spreader cab control consists of a power/
kill switch, a start switch, a throttle speed con-
trol switch, and a clutch on/off switch.
DWG. NO. 3184
Before starting the engine, check that the clutch
switch is in the OFF position.
To start the engine, first turn the power switch
to RUN, then hold the throttle control switch at
INCREASE for 3 seconds to choke the engine.
Hold the start switch at START until the engine
is running.
IMPORTANT: Do not hold the start switch
for longer than 15 seconds at a time when
attempting to start the engine. Allow the
starter motor to cool for 2 minutes between
attempts.
Once the engine has started, move the throttle
control switch to DECREASE until the engine
runs at the desired speed.
IMPORTANT: Prolonged operation of the en-
gine at full or partial choke may cause pre-
mature engine wear or failure due to gaso-
line diluted oil or fouled spark plug.
The engine can also be started by using the re-
coil starter with the power switch in the RUN
position.
CAUTION: If the battery has been re-
moved and machine is to be hand
started, be sure the positive cable
(red) at the battery end has the terminal
taped to prevent sparking to ground when
the engine is running.
The electric clutch can be engaged or disen-
gaged at any engine speed. However, since
engagement time and torque is almost instanta-
neous, to prevent premature spinner chain fail-
ure and chain tension loss, it is recommended
that the electric clutch be engaged at the lowest
possible engine speed without killing the en-
gine.
Burnishing the clutch is necessary to achieve
rated torque capacity. Never perform burnishing
while drive is loaded. New clutches and clutches
that have not been used for a long time, should
be burnished before full load operation by the
following procedure:
1. Rotate the clutch and check for rubbing or
interference. Reinstall chain, do not over
tighten.
2. Run at 50% throttle.
3. Engage and disengage the clutch 25 times.
(10 seconds on/10 seconds off).
4. Increase to 75% throttle.
5. Engage and disengage the clutch 25 times.
(10 seconds on/10 seconds off).
Disengage the clutch and move the power
switch to the STOP position when done using
the spreader.
