2.0 What the Machine is Designed For
2.1 Applicaons
The CAMON SG30 Stump Grinder has been designed by Tracmaster for removing
tree stumps from above and below the surface of the ground.
The benet of removing a tree stump is that it allows the landscape to be redesigned
without the stump.
The teeth of the CAMON SG30 Grinder are designed to grind TREE STUMPS ONLY
- they are NOT designed to make contact with solid ground at any point during
operaon.
The machine will be damaged should the teeth connuously come into contact
with solid ground.
DO NOT use the CAMON SG30 Grinder for cung grass or digging the ground.
These operaons will result in damage to the machine.
Operang the machine on non-grass surfaces such as concrete or tarmac will cause
damage to the SG30 Grinder.
DO NOT use the Stump Grinder if there is a likelihood of high temperatures.

5.0 SafetyInstrucons–Pre-Operaon
5.1 BasicSafetyInstrucons
Before starng the machine, read and understand these operang instrucons.
5.2 MainComponentsandOperangElements
Below is a descripon of the main components of the SG30 Stump Grinder and how
they operate.
5.3 Engine and Drive
The Honda GX390 is a four stroke engine that runs on
standard unleaded fuel.
The engine is air cooled and therefore it is important
that the grille covering the recoil rope is kept clear from
debris.
The engine air lter cleans the air sucked in by the
engine. A clogged air lter will reduce performance.
The engine is ed with a fuel on/o lever and a choke lever. Read the engine
operang instrucons to understand the operaon of these levers.
5.4 OperangLever
The engine of the SG30 Stump Grinder is controlled
by the Operator Presence Control (OPC) lever (g. 3).
This lever turns the engine ON or OFF.
Squeezing the Operator Presence Control lever allows
the engine to be started.
Leng go of the Operator Presence Control lever
turns the engine o.
5.5 ThroleLever
The throle lever controls the engagement and speed of the rotor disc and teeth.
If the throle lever is in the SLOW posion the engine revoluons of the crank sha
is too low for the centrifugal clutch to engage and transfer power to the rotor sha
and cung disc.
Posioning the throle lever in the FAST posion will engage the centrifugal clutch
and the rotor sha and cung disc will rotate.
WARNING: MOVING THE THROTTLE FROM SLOW TO FAST MUST ALWAYS
BE CARRIED OUT IN A CONTROLLED MANNER WITH THE OPERATOR UNDER
COMPLETE CONTROL OF THE MACHINE.

5.6 Choke Lever
The choke lever is used to help start the engine when it is cold or being started for
the rst me.
Refer to the engine instrucons for detailed instrucons on the operaon of the
choke lever.
5.7 Rotor Disc and Teeth
The main rotor disc holds 8 teeth holders with each holder holding one carbide-
pped cung tooth.
Each tooth can be turned through three posions in the holder, allowing the teeth
to be used three mes before they need changing.
5.8 Commissioning
Prior to operaon it is necessary to check the engine oil level and add engine oil
level to the levels indicated in the table in secon 6.2.
The engine fuel tank will not contain fuel so will need lling to the recommended
level before use.
5.9 GeneralSafetyInstrucons
Be aware of all the safety requirements for the machine.
Visually check the machine for operaonal safety, complete components and xed
guarding prior to each use.

6.5 Operaon-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 rotang
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 direcon should be considered, as it inuences
the direcon in which dust and wood chips will be
directed.
Never operate the machine aer dark. Night-me operaon will not allow the
operator to see the stump and danger zone adequately enough for safe operaon.
Always allow a cold engine me to warm up before cung a stump.
Only the poron of cung wheel within the 80o area shown in g. 11 should engage
the stump.
Never undercut the stump or use the boom of the cung wheel for cung
purposes.

6.6 ProcedureforCungtheStump
PosiontheStumpGrinder(g. 12).
Place the machine into posion with the cung
wheel near the top edge of the stump.
Removenearbyrootsrst(g. 13).
Conduct the pre-starng inspecon if not already
done and start the engine as per the operang
instrucons above. Allow the engine to “warm
up” for 30 seconds with the engine revs set to
the MIN posion prior to starng to remove the
stump.
Lock the brake by pulling back the brake lever.
Make sure the throle is set to “MAX”. The cuer
wheel is thus accelerated to cung speed.
Swing the cung wheel to one side, then lower it
approximately 1” into the nearside roots that are
buried at the foot of the stump.
Swing the cung wheel across the roots, back
and forth, lowering cung wheel approximately
1” before each sweep, unl the roots are
suciently removed.
Raise the cung wheel unl the centre of the
cung wheel is just above the top of the stump.
Allow the cuer wheel to stop rotang, release the brake, and reposion the
machine. Lock the brake again.
Remove the main part of the stump (g. 14).
Make sure the throle is set to “MAX”. The cuer wheel is thus accelerated to
cung speed.
Direct the cuer wheel against the stump, beginning with the nearside top corner
of the stump, and steadily sweep it across the stump le and right, cung away 1”
of wood with each sweep.
Raise and lower the cuer 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 reposioned, and connue cung.
Shut o the engine by releasing the Operator Presence Control (OPC) lever.

HelpfulpsforoperangtheStumpGrinder
Use smooth, comfortable movements while operang.
When it is desired to cut smaller roots, it may be more eecve to do so before,
rather than aer, cung the stump.
Should the chip build-up become excessive when cung, shut o the machine,
wait for the cung wheel to stop rotang, retract the machine from the stump,
and rake away chips.
On larger stumps, when cung 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 connue removal, or by lling the hole with chips before connuing.
WARNING: NEVER USE THE STUMP GRINDER IN POOR LIGHT OR AT NIGHT.
6.7 ProcedureforUnexpectedShutDown
Release the Operator Presence Control (OPC) lever.
Push down on the handlebars to raise the teeth into the air.
Ensure the rotor sha and blades have stopped rotang prior to moving the
machine.
6.8 Residual Risks of the SG30 Stump Grinder
The rotor sha will connue to rotate for several seconds once the operang lever
has been released. Ensure that the blades have stopped rotang prior to moving or
lng the machine.
The SG30 Stump Grinder is designed to be pushed by the operator both during
transportaon and operaon. The SG30 is ed with a wheel brake on the le hand
wheel that may be used to hold the machine on sloped areas.

7.2 Basic Maintenance
Check that all guards are ed securely.
Ensure the cable connecng the operang lever to the engine is securely fastened
at both ends and shows no sign of wear.
Check the pressure of pneumac tyres and ensure that they do not show any
indentaons or signicant wear and tear.
Ensure the wheels are held securely and the bolts that hold the wheels onto the
axles are in place.
Check the wheels rotate smoothly and without hindrance.
Grease the cuer sha bearings daily.
7.3 Advanced Maintenance
We strongly recommend that an Authorised Representave is consulted prior to
any major machine maintenance projects.
7.3.1 RotangTeeth
InspeconCheck:
A tooth that has become rounded on its
leading edge (g. 15a) can be rotated to
an unworn posion facing forwards so that
the SG30 Stump Grinder can connue to
funcon properly.

To Rotate Teeth:
To rotate a tooth, rst loosen the locknut
that holds the tooth in its holder on the
tooth pocket.
Li and rotate the tooth to the next
indexed posion so a sharp edge is facing
forwards on the machine.
Re-ghten the nut to 27Nm to secure the
tooth ghtly in posion.
7.3.2 Replacing Teeth
InspeconCheck:
Blades that have been worn so that they have become rounded must be
changed for the SG30 Grinder to funcon properly (g. 15a).
To Replace Teeth:
Loosen and remove the locknut and spacer that hold the tooth in its holder
on the tooth pocket.
Slide the worn tooth out of the tooth pocket.
Insert a new tooth with sharp carbide edges and re-t the spacer. Ensure
that the spacer is installed with the chamfered
edge facing downwards so that it ts inside the
tooth holder (g. 16).
Tighten the lock nut that holds the tooth in the
tooth holder securely to 27Nm.
7.3.3 Changing the Teeth Holder
InspeconCheck:
Teeth holders that are damaged or which can
move whilst the bolts are fully ghtened must
be replaced to ensure the safe retenon of the
teeth.
To Replace Teeth Holders:
There are two types of teeth holder on the
cung disc, a straight tooth holder and an
angled tooth holder (g. 17). There a four of
each type, eight in total, and they are ed in
pairs, one of each type either side of the cung
disc.

The holders must be ed alternately, eg, the rst pair would be a straight
holder and an angled holder, then the second pair would be an angled holder
and a straight holder, and so on.
When changing the teeth holders it is essenal that a similar type of holder
is posioned in the same posion as the holder that was removed.
WARNING: INCORRECT FITTING OF TEETH HOLDERS ONTO THE
ROTATING CUTTING DISC CAN SERIOUSLY AFFECT PERFORMANCE
AND MAY DAMAGE YOUR MACHINE.
Loosen and remove the two bolts used to clamp the two teeth holders either
side of the rotang cung disc.
Replace the tooth holders with a similar tooth holder type and reposion
and ghten the bolts to hold them in place (g. 18).
The tooth holders are reversible; each holder has one threaded hole and
one counter-bored hole which allow the tooth holder bolts to feed into the
wheel from opposite sides to ensure a strong secure setup.
The tooth holder bolts must be ghtened to a torque seng of 244Nm if
using anseize (copper slip) or 325Nm dry.
7.4 Engine
7.4.1 Check Engine Oil Level
This is to be checked prior to each use and every 8 hours during operaon.
Check only when the engine is o and in a horizontal posion.
Clean the oil ller plug and its surrounding parts.
Remove the oil ller plug. Clean the dipsck with a clean cloth and put the
oil ller plug all the way back into the engine. Remove the oil ller plug and
check the oil level.
Rell the oil if indicator shows more is required. For the Honda GX160 the
recommended oil is SAE 10W/30 API SJ or equivalent.
7.4.2 Change Engine Oil
Refer to the engine manufacturer’s manual for locaon of components and
more detailed assistance.
Do not change the oil if the engine is hot.
The rst oil change is aer 50 hours of work.
Subsequent oil changes should be made aer each 100 hours of work.
At extreme temperatures or condions change the oil aer every 50 hours.
