STARTING PROCEDURE
START THE ENGINE
a) Lock travel wheel by pulling brake lever fully back
b) Turn fuel tap to ON
c) Turn engine ON/OFF switch to ON.
d) Make sure throttle is in slow speed position.
e) If the engine is cold, move the choke lever to the closed/start position.
f) Raise the cutter wheel 4 to 5 inches off the ground by pushing downwards on the handle bar, hold
it in that position.
g) Pull the starter rope lightly until resistance is felt then pull briskly. Do not allow the pull cord to
snap back, return it by hand to prevent damage to the starter. This may cause the cutter wheel to
rotate, keep everyone away.
h) When engine starts, or res, move the choke lever to the open/run position.
i) If the engine is cold, allow the engine to tick over (throttle set to slow speed) for a few minutes
before cutting, increase engine rpm to high speed setting before use. Please note that the centrifugal
clutch may slip which will cause excessive wear if the machine is used at speeds below half throttle.
REMOVING STUMPS
START THE ENGINE
Remove all loose pieces of wood, stones, wire and other debris from the area before beginning
stump removal.
Wind direction should be considered, as it inuences the direction in which dust and wood chips
are directed.
Dig away the earth and remove any stones near the tree stump that may interfere with your work.
Check that the ground is free of foreign objects, such as electrical cables, barbed wire, etc.
17
Cut or trim the stump as low to ground as required using a power saw.
Never operate the stump grinder after dark. There will not be adequate lighting for the operator to
use the machine safely.
Always allow a cold engine time to warm up before use.
For best results, only the portion of cutting wheel within the 80-degree area shown below should be
in contact with the stump.
Never leave controls when the cutting wheel is rotating and stop the engine when machine is left
unattended.
REMOVING STUMPS – OPERATION TIPS
Use smooth, comfortable side to side movements while operating, pivoting the arc on the locked
left hand wheel.
When it is desired to cut smaller roots, it may be more effective to do so before rather than after
cutting the main stump.
Should the chip build-up become excessive when cutting, stop the engine, wait for the cutting wheel
to stop rotating, retract the machine from the stump and rake away the chips.
In order to prevent the wheels becoming stuck in the hole. Move the grinder to the other side of the
stump to continue removal or by lling the hole with chips before continuing.
PREPARE THE GRINDER AT THE STUMP
Place the stump grinder into position with the cutting wheel near the top edge of the stump.
18
REMOVING ROOTS
Make sure the throttle is set to high speed, the cutter wheel will accelerate to cutting speed
Swing the cutting wheel to one side, then lower it into the nearest roots that are buried at the foot
of the stump.
Swing the cutting wheel before each sweep, until the roots are sufciently removed.
Raise the cutting wheel until the center of the cutting wheel is just above the top of the stump.
Allow the cutter wheel to stop, release the brake and reposition the machine.
Lock the brake again.
CUTTING THE FULL STUMP
Make sure the throttle is set to high speed. The cutter wheel will accelerate to cutting speed
Direct the cutter wheel against the stump, beginning with the nearest top corner of the stump, and
steadily sweep it across the stump left and right, cutting away 1/2 inch/ 13mm of wood with each
sweep.
Raise and lower the cutter wheel between sweeps by lowering and raising the control handle.
19
Roll the machine forward and back, by pushing and pulling on the control handle. To do this, release
the park brake. Relock it when the machine has been repositioned and continue cutting.
