Lawn Scarifier
The CAMON LS42 Lawn Scarifier has been
designed by Tracmaster for removing the dead
thatch and moss from lawns and other grassed
areas.
The benefit of scarifying a lawn is that it allows
air, water and nutrients to reach the roots of the
grass whilst removing unwanted dead and foreign
material.
Starting the Lawn Scarifier
This machine is operated by lifting the lever located underneath the top of the handlebar.
It is a two-stage process.
1. Press the grey lever locking catch.
2. Press the black operating lever.
The black lever increases the engine speed to a level that will engage the centrifugal clutch fitted to
the engine drive shaft.
Once the clutch has been engaged it will transfer the engine power to the rotor shaft that will rotate
at high speeds within the chassis of the Scarifier.
Height Adjustment
The height of the blades of the lawn Scarifier is altered using the two large knobs at the front of the
machine.
The top knob is connected to the centre of the front axle via a threaded rod. Rotating the knob in
each direction will raise or lower the front axle in relation to the main chassis of the machine and in
turn alter the height of the blades with the chassis.
The second knob located below the top knob on the threaded rod is used to fix the position of the
threaded rod and consequently the height of the blades relative to the front axle.

Collection Bag
The collection bag will collect the thatch and moss that is removed from a grass area. Use the central
lifting handle when connecting or disconnecting the bag from the machine.
Always stop the engine and wait for the blades to stop rotating before removing or replacing the
collection bag.
To attach the collection bag onto the machine, first lift the safety back flap on the rear of the
machine chassis with one hand. Then whilst holding the bag with your other hand guide the two
small metal rods protruding from either side of the collection bag frame into the two channels that
have been formed to hold the bag.
Rotor Shaft
The main rotor shaft holds three rods with each rod holding 10 hardened steel blades. The blades
are separated using spacers and springs. Each set of 10 blades on a rod is offset from the other two
rods.

Preparation of the Grass Area
•Before scarifying can be carried out the grass must be cut short and be cleared of any
objects such as stones, sticks, wires or bones that would damage the machine or be picked
up and thrown by the rotating blades.
•Do not operate the engine in a confined space where dangerous carbon monoxide fumes
can collect.
WARNING:
•Using this machine on long grass will damage the machine. We recommend cutting the grass
before using the lawn scarifier
•Do not operate the Scarifier on wet lawns or in rainy weather.
Safety When Using the Lawn Scarifier
1. Always be sure of footing on slopes.
2. Walk never run.
3. Always work across the face of slopes, never up and down.
4. Exercise extreme caution when changing direction on slopes.
5. Use extreme caution when reversing or pulling the machine towards you.
6. Stop the tines if the machine has to be tilted for transportation. Do not operate the tines
when crossing surfaces other than grass and when transporting the machine to and from the
working area.
7. Never operate the machine with defective guards, or without safety devices, for example
deflectors and or catchers in place.
8. Do not change the engine governor settings or over speed the engine.
9. Disengage all tine starting levers before starting the engine.
10. Start the engine carefully according to the instructions and with feet well away from the
tines.
11. Do not tilt the machine when starting the engine.
12. Do not put hands or feet near or under the rotating parts. Keep clear of the discharge

WARNING:
THE BLADES MUST NOT BE ALLOWED TO TOUCH THE GROUND AT ANY POINT DURING
OPERATION.
•If using the collection bag, ensure that it is mounted correctly and is secure.
•Lift the operating lever to engage the rotor shaft and walk at a slow steady pace pushing the
machine ahead of you.
•To turn the LS42 Scarifier 180 degrees, release the operating lever, put light downwards
pressure on the handlebars and rotate the machine on its rear wheels.
•Do not work the Scarifier on slopes of more than 20 degrees and always work across the
slope, not up and down it.
•Once the collection bag has become full, release the operating lever, turn off the engine and
ensure the rotor shaft has stopped turning. Remove the collection bag and empty. Reattach
the bag securely and re-start the engine to continue scarifying.
Stop the engine and disconnect the spark plug wire before:
1. Clearing blockages
2. Checking, cleaning, or working on the machine
3. After striking a foreign object
4. If the machine starts to vibrate abnormally.
Stop the engine and disconnect the spark plug wire.
1. Whenever you leave the machine
2. Before refuelling
Reduce the throttle setting during engine shut down and turn the fuel off on the engine at the
conclusion of scarifying.
Procedure for Unexpected Shut Down
1. Release the operating lever.
2. Turn the engine operating switch located on the engine to the OFF position.
3. Ensure the rotor shaft and blades have stopped rotating prior to moving the machine.
How to Clear Unwanted Debris from the Underside of the Machine
1. Ensure that the engine has been turned off, remove the spark plug wire and the rotor shaft
has stopped turning.
2. Turn the engine fuel tap to the off position.
3. Attach a lifting hoist to the top handlebar and lift the machine so that it tilts forward onto its
front wheels. As the underneath of the chassis becomes exposed it is possible to see and
remove any unwanted debris.

WARNING:
ALWAYS TILT THE LAWN SCARIFIER FORWARDS TO AVOID OIL IN THE ENGINE FLOODING INTO
AREAS WHERE IT WILL CAUSE DAMAGE.
Residual Risks of the Lawn Scarifier
The rotor shaft will continue to rotate for a couple of seconds once the operating lever has been
released. Ensure that the blades have stopped rotating prior to moving or tilting the machine.
This machine has been designed to be pushed by the operator both during transportation and
operation. It has no brake system and therefore the operator must hold firmly onto the machine on
sloped areas.
