Forest Master Models: FM9DD/FM14DD/FM18DD
14
Operation
• Move the choke control lever (if used for cold engine) slowly back to the “RUN” position when the engine is
running well.
• If the Wood Chipper has not been running (cold engine), warm up the engine by running the engine at half
throttle for 1 to 2 minutes, then advance the engine throttle control to the maximum speed.
• If the electric start does not turn the engine over then the battery may have insufficient charge. Start the
engine using the pull start. The engine will trickle charge the battery, 30 minutes of running should pro-
vide sufficient charge to start the next time.
FM9DD OULL START
Make sure the fuel shut-off valve is in the “ON” position.
• Move the choke control lever to the “CHOKE” position (As this is a lean burn engine, it may require some
choke when starting warm).
• Move the throttle control lever to the “FAST” position.
• Turn the ignition switch to the “ON” position.
• Grasp the recoil starter handle and slowly pull until you feel resistance. If the pull start is tight and does
not pull, the chipper has a blockage and should be cleared before starting. Let the cord retract a little bit
then pull the cord rapidly to start the engine. One or two pulls usually starts the engine.
• Move the choke lever (if used for cold engine) slowly back to the “RUN” position when the engine is
running well.
• Warm up the engine by running the engine at half throttle for 1 to 2 minutes, then advance the engine
throttle control to mulching speed.
Stopping the Engine
Ensure no fragments remain inside the mulcher when turning it off. Allow to run for 1 minute without feeding
in any material before stopping the chipper. This will help to avoid the risk of blockage for the next time you
start the machine.
• Move the throttle lever to “IDLE”
• Turn the ignition switch to the “OFF” position.
Engine Does Not Start
The LCT engine is a reliable engine that starts very easily. There are two safety cutouts that inhibit the
ignition, one is the hopper microswitch, the other is the engine oil level alert, if the engine does not fire then
it is almost certainly one of these cutouts is in operation.
• Check that the hopper bolt(51) is tightened, if this is loose the ignition is inhibited.
• Check that the chipper is level. If it is at an angle then the oil level sensor could misread and cut the
ignition.
• Check the oil level, (the FM9DD requires a minimum of 600ml of oil, the FM14DD & FM18DD require 1.1
litres of oil) any less than this and the engine will not fire. Add the required minimum amount of oil and
if the engine does not fire or runs erratically gradually add a little more. Do not add anymore than an
additional 50ml.
• Check that the air filter element is clean and not obstructed. If there is oil in the air filter then the engine
has been overfilled with oil. With the machine standing level, remove the crankcase oil filler plug and
allow any excess oil to run out until it is just dripping over the lip.
See the Troubleshooting guide in the maintenance section for other problems.
