before operating the machine to
prevent injury
CAUTION –keep hands and feet
away from openings on the machine
to prevent injury
AFTER A PERIOD OF INACTIVITY
Ensure the following checks have been done on the CM90/95 before operation after a
long period of inactivity:
Check that the machine is undamaged and all guards are attached
Check all the mechanical parts of the machine are not rusty and are in working
condition
Ensure the flywheel and the blades rotate freely, are sharp and are connected
to the machine
Ensure that the engine has sufficient oil and fuel
Check all nuts and bolts are tight

OPERATING INSTRUCTIONS
BEFORE USE
Before operating the machine it is important to ensure the following to use the
machine to its full capability and to keep the operator and the surrounding area safe.
Make sure that the operator has read and understood how to use the engine as
per the manufacturer’s instructions
Ensure that the oil and fuel in the engine are as per the engine manufacturers
instructions
Check that all guards and parts are in place
Make sure the throttle control is at its lowest setting. At idle the centrifugal
clutch should be disengaged
Ensure that the CM90/95 is located on flat, even ground and that there are no
people or animals in the vicinity of its working function, including the area
surrounding the discharge chute
Ensure that the operator has read and understood this manual, including how to
control the machine
Wear the prescribed safety equipment
Check that the material to go through the CM90/95 does not contain nails,
ropes or any metal object that can damage the machine whilst it is being
mulched
DURING OPERATION
Once satisfied that the above criteria have been met, turn on the engine as per the
manufactures instructions. Once running:
Gently increase the throttle until the clutch engages and the blades rotate.
Operate the CM90/95 at near full throttle for optimal performance
For the CM90/95 all branches go through the chipper chute. It is best if the
thickest end of the branch gets fed into the chipper chute first; generally this is
the end that you cut the branch at. Sometimes it may be required to prune the
side branches to fit the main branch into the chipper chute. Ensure this is done
before you start chipping. The CM90/95 generally will draw the branches in and
on no occasion do you need to put your hand inside the chipper chute. Once
the branch has been put through, put the leaves and other organic waste
through the mulching chute at the top of the machine. Once again, do not put
your hands in the mulching chute.
To adjust the cutting of the CM90/95, the discharge bars can be taken out or
put in. Ensure that when adjusting the amount of discharge bars in the machine
that the machine is off and the flywheel has stopped rotating. The discharge
bars are important for the efficient use of the machine. They are there for the
purpose of allowing the CM90/95 to handle multiple types of material without

10
clogging. For an example let the top bar be no.1 and the bottom bar be no. 5.
For dry materials such as gum trees etc. leave all the bars in. For wetter
materials, plants, manure, flowers etc with higher water content, take out no. 3
and no. 5. For newspapers and cardboard, take out no. 5, 4 and 3. Generally, if
what is being inserted into the machine is not coming out, there are too many
bars in place.
MACHINE BLOCKAGE
During operation it is possible that a branch or pruning with a diameter higher than
the working capacity of them machine is entered, and blocks the rotation of the
flywheel.
To remove the blockage, ensure that the machine has been turned off, the spark plug
has been disconnected and that the flywheel has no power supply that will make it
rotate while the material is being removed. Once the blockage has been taken out,
the machine can be re-started.
AFTER USE
When you have finished operation of the machine and have turned the engine off:
Allow machine to cool down
Check the machine over to see if there are any irregularities that could impede
your next use
Check fuel and oil levels for next use

11
GENERAL MAINTENANCE
For the servicing of the machine it is strongly recommended, for safety and quality of
the maintenance, for this to be conducted by authorised professionals from Truyard
authorised dealers who know the machine.
ADJUSTMENT OR REPLACEMENT OF THE CHIPPER BLADES
Disconnect the spark plug to
ensure that the machine will not
receive power whilst you are
working on the flywheel
Take off the hopper plate of the
machine using a 13mm spanner.
Place a bar through the flywheel.
Ensure that the flywheel doesn’t
rotate when this bar is in place
by pulling the engine cord.
Remove the chipper chute using
a 13mm spanner to give access
to the bolt holding the chipper
blade.

12
Using a 19mm spanner, loosen
the nut that connects the chipper
blade to the flywheel.
CAUTION –THE CHIPPER
BLADE IS SHARP AND CAN
CAUSE INJURY
In order to fully remove the nut
and bolt, use an 8mm Allen key
to counter the force from the
spanner. Remove the nuts and
bolts from the chipper blade.
Once all three have been
removed, take out the chipper
blade. The chipper blade will
come out of the chipper chute
entrance. When putting the
blades back in you should
always replace the nuts and bolts
and Loctite the thread for safety.
CAUTION –THE CHIPPER
BLADE IS SHARP AND CAN
CAUSE INJURY

13
ADJUSTING BELT TENSION
Remove the protective cover that
sits over the belts with a 13mm
socket.
Using a 17mm spanner, loosen
the nuts that connect the engine
to the frame of the machine.
Once all four have been
loosened, slide the engine on the
rails to increase the belt tension.
Re-tighten the nuts and ensure
that the engine is secure.
