Safety Instructions Starting and OperatingMake sure that all shields, guards, and curtains are in
place, and are in good condition prior to operating the machine.
Only responsible, properly instructed individuals should
operate this machine. Inexperienced operators must always be carefully
supervised.
Check cutting wheel for damage or missing teeth, and replace
as necessary.
Make sure that no-one is working on, underneath, or close to
the machine before starting the engine or beginning to move the machine. Make
sure that the area is free of personnel.
Check stumps to be removed for embedded nails, wire, metal
fence posts, and other metallic objects, and for rocks or other buried
impediments which may become dangerously thrown or cause unexpected machine
movements when hit by the cutting wheel.
Ensure that everyone in the vicinity is aware of the DANGER
ZONE associated with this machine – this is an 8m radius around the machine
(see diagram below). You and they must avoid the DANGER ZONE at all times when
the machine is in operation. The SAFE ZONE for the operator, subject to the
operator wearing the appropriate safety equipment (PPE).
To Start the Engine
Lock the left hand wheel by pulling Brake lever fully back.
Squeeze the Operator Presence Control lever to turn the
engine on.
Make sure throttle is in “MIN” position.
If engine is cold, move the choke lever to the ON position.
Raise the cutter wheel off the ground, approximately 4” to
5”, by pushing downward on the control handle. Hold it in that position.
WARNING: The next step may cause the cutter wheel to
rotate. Keep everyone away!
Pull the starter rope lightly until resistance is felt, then
pull briskly.
Move the Choke lever to the “ON” position.
WARNING: The next step causes the cutter wheel to rotate.
Keep everyone away!
Move the Throttle to “MAX” position. If the engine is
cold, allow the engine to idle (Throttle set to “MIN” position) for a few
minutes before cutting.
Once the engine is running, move the Choke lever to the
“OFF” position.
To Stop the Engine
Tilt the stump grinder to raise the teeth into the air.
Move the throttle lever to the “MIN” position
Release the operator presence lever.
Ensure the blades have stopped rotating prior to moving the
machine.
Turn the fuel tap lever to the “OFF” position.
WARNING: THE EXHAUST COVER MAY BE HOT – DO NOT TOUCH.
Safety
Equipment!
The SG30 operator must be wearing:
• Ear Defenders
• Gloves
• Protective Footwear
• Safety Glasses
• Forestry Helmet – recommended
Operation – Removing Stumps
Before grinding a stump the area must be cleared of any
objects such as stones or metal that would damage the grinder or be picked up
and thrown by the rotating blades.
WARNING: REMOVE ALL HARD OBJECTS SUCH AS GRAVEL, ROCKS
AND STONES TO REDUCE THE LIKELIHOOD OF THESE OBJECTS BEING THROWN BY THE STUMP
GRINDER.
Remove all loose pieces of wood, stones, wire and other
debris from the work area before beginning stump removal.
Wind direction should be considered, as it influences the
direction in which dust and wood chips will be directed.
Never operate the machine after dark. Night-time operation
will not allow the operator to see the stump and danger zone adequately enough
for safe operation.
Always allow a cold engine time to warm up before cutting a
stump.
Only the portion of cutting wheel within the 80o area shown
above should engage the stump.
Never undercut the stump or use the bottom of the cutting
wheel for cutting purposes.

Conduct the pre-starting inspection if not already done and
start the engine as per the operating instructions above. Allow the engine to
“warm up” for 30 seconds with the engine revs set to the MIN position prior to
starting to remove the stump.
Lock the brake by pulling back the brake lever.
Make sure the throttle is set to “MAX”. The cutter wheel is
thus accelerated to cutting speed.
Swing the cutting wheel to one side, then lower it
approximately 1” into the nearside roots that are buried at the foot of the
stump.
Swing the cutting wheel across the roots, back and forth,
lowering cutting wheel approximately 1” before each sweep, until the roots are
sufficiently removed.
Raise the cutting wheel until the centre of the cutting
wheel is just above the top of the stump.
Allow the cutter wheel to stop rotating, release the brake,
and reposition the machine.
Lock the brake again.
Make sure the throttle is set to “MAX”. The cutter wheel is
thus accelerated to cutting speed.
Direct the cutter wheel against the stump, beginning with
the nearside top corner of the stump, and steadily sweep it across the stump
left and right, cutting away 1” of wood with each sweep.
Raise and lower the cutter wheel, between sweeps as needed,
by lowering and raising the control handle.
Roll the machine forward and back by pushing and pulling on
the control handle, between sweeps as needed, in order to progress into the
stump. To do this, release the brake. Relock it when the machine has been
repositioned, and continue cutting.
Shut off the engine by releasing the Operator Presence
Control lever.
Helpful tips for operating the Stump Grinder
Use smooth, comfortable movements while operating.
When it is desired to cut smaller roots, it may be more
effective to do so before, rather than after, cutting the stump.
Should the chip build-up become excessive when cutting, shut
off the machine, wait for the cutting wheel to stop rotating, retract the
machine from the stump, and rake away chips.
On larger stumps, when cutting from one side, eventually a
tyre may tend to roll into the hole. This may be prevented by moving the
machine to another side of the stump to continue removal, or by filling the
hole with chips before continuing.
WARNING: NEVER USE THE SG30 STUMP GRINDER AT NIGHT.
