toys and other foreign objects, which could be tripped over or picked up and thrown by the scarifier.
Thrown objects can cause serious personal injury.
7. Plan your scarifying pattern to avoid discharge of material toward roads, pathways, bystanders and the
like. Also, avoid discharging material against a wall or obstruction, which may cause discharged material to
ricochet back toward the operator.
8. To help avoid tine contact or a thrown object injury, stay in operator zone behind handles and keep
children, bystanders, helpers and pets at least 20 metres from scarifier while it is in operation. Stop
machine if anyone enters area.
9. Always wear safety glasses or safety goggles during operation and while performing an adjustment or
repair to protect your eyes. Thrown objects which ricochet can cause serious injury to the eyes.
10. Wear sturdy, rough-soled work shoes and close-fitting trousers and shirts. Shirts and trousers that cover
the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet,
sandals, slippery or light- weight (e.g. canvas) shoes.
11. Do not put hands or feet near or under rotating parts. Always keep clear of discharge area, as the rotating
tines can cause injury.
12. Never operate the scarifier without proper shields, guards, control lever or other safety protective devices
in place and working.
13. Never operate the scarifier with damaged safety devices. Failure to do so, can result in personal injury.
14. Many injuries occur as a result of the tines being pulled over the foot during a fall caused by slipping or
tripping. Do not hold on to the scarifier/aerator if you are falling; release the handle immediately.
15. Never pull the scarifier back towards you while you are walking. If you must back the scarifier away from a
wall or obstruction, first look down and behind to avoid tripping and then follow these steps:
A. Step back from the scarifier/aerator to fully extend your arms.
B. Be sure you are well balanced with sure footing.
C. Pull the scarifier/aerator back slowly, no more than halfway towards you.
D. Repeat these steps as needed.
INSTRUCTION MANUAL

16. Do not operate the scarifier while under the influence of alcohol or drugs.
17. The OPC/Brake lever is a safety device. Never attempt to bypass its operation. Doing so makes the safety
device inoperative and may result in personal injury through contact with the rotating tines. The control
lever must operate easily in both directions and automatically return to the disengaged position when
released.
18. Never operate the scarifier in wet grass. Always be sure of your footing. A slip and fall can cause serious
personal injury. If you feel you are losing your footing, release the OPC/Brake lever immediately and the
spindle will stop rotating within three seconds.
19. Operate only in daylight or good artificial light. Walk, never run.
20. Stop the tines when crossing gravel drives, paths or roads.
21. If the machine starts to vibrate abnormally, stop the engine and check immediately for the cause.
Vibration is generally a warning of trouble.
22. Shut the engine off and wait until the spindle comes to a complete stop before cleaning the discharge
area. The tines continue to rotate for a few seconds after the OPC/Brake lever is released. Never place any
part of the body in the scarifier area until you are sure the tines have stopped rotating and the spark plug
cap removed from the spark plug and contact cannot be made between the two.
23. Never operate the scarifier without proper shields, discharge cover, OPC/Brake lever or other safety
protective devices in place and working. Never operate with damaged safety devices. Failure to do so can
result in personal injury.
24. Muffler and engine can become hot and cause burns. Do not touch!
25. Only use parts and accessories made for this machine by the manufacturer. Failure to do so can result in
personal injury.
26. When starting the engine, pull cord slowly until resistance is felt, then pull rapidly. Rapid retraction of
starter cord (kickback) will pull hand and arm towards engine faster than you can let go. Broken bones,
fractures, bruises or sprains could result.
27. If situations occur which are not covered in this manual, use care and good judgement. Contact your
nearest Approved Service Dealer for assistance
SLOPE OPERATION
Slopes are a major factor related to slip and fall accidents, which can result in severe injury. Operation on
slopes requires extra caution. If you feel uneasy on a slope, or it is greater than 15 degrees, do not scarify on it.
Do:
1. Scarify across the face of slopes; never up and down. Exercise extreme caution when changing direction
on slopes.
2. Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can
hide obstacles.
3. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing
your balance, release the OPC/Brake lever immediately and the tines will stop rotating within three (3)
seconds.
Do Not:
1. Do not scarify near drop-offs, ditches or embankments, you could lose your footing or balance.
2. Do not scarify on slopes greater than 15 degrees.
3. Do not scarify on wet grass. Unstable footing could cause slipping.
CHILDREN
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted
to the scarifier and the activity. They do not understand the dangers. Never assume that children will remain
where you last saw them.
1. Keep children out of the scarifying area and under care of a responsible adult other than the operator.
2. Be alert and turn the scarifier off if a child enters the area.
3. Before and while moving backwards, look behind and down for small children.
4. Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may
obscure your vision of a child who may run into the scarifier.
5. Keep children away from hot or running engines. They can suffer burns from a hot muffler.
6. Never allow children under 16 years of age to operate this machine. Children 16 and over should read and
understand the instructions and safe operation practices in this manual and on the machine and be
trained and supervised by an adult.

SERVICE
Safe Handling of Petrol:
1. To avoid personal injury or property damage use extreme care in handling petrol. Petrol is extremely
flammable, and the vapors are explosive. Serious personal injury can occur when petrol is spilled on
yourself or your clothes, which can ignite. Wash your skin and change clothes immediately.
2. Use only an approved petrol container.
3. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle before filling.
4. Remove petrol-powered equipment from the truck or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment on a trailer with a portable container, rather than from a petrol
dispenser nozzle.
5. Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
6. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
7. Never fuel machines indoors because flammable vapors will accumulate in the area.
8. Never remove petrol cap or add fuel while engine is hot or running. Allow engine to cool at least two
minutes before refueling.
9. Never over fill fuel tank. Fill tank up to 80% capacity to allow for expansion.
10. Replace petrol cap and tighten securely.
11. If petrol is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5 minutes
before starting engine.
12. Never store the machine or fuel container near an open flame, spark or pilot light on petrol appliances.
13. To reduce fire hazard, keep machine free of grass, leaves, or other debris build-up. Clean up oil or fuel
spillage and remove any fuel-soaked debris.
14. Allow machine to cool at least 5 minutes after use, before storing.
General Service:
1. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an
odorless and deadly gas.
2. Before cleaning, repairing, or inspecting, make certain the tines and all moving parts have stopped.
Disconnect the spark plug wire and ground against the engine to prevent unintended starting.
3. Check the tines and engine mounting bolts at frequent intervals for proper tightness. Also, visually inspect
tines for damage. Replace with the original equipment manufacture’s (O.E.M.) parts only, listed in this
manual. “Use of parts which do not meet the original equipment specifications may lead to improper
performance and compromise safety!”
4. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
5. Never tamper with safety devices. Check the correct operation regularly.
6. After striking a foreign object, stop the engine, disconnect the spark plug wire and ground against the
engine. Thoroughly inspect the scarifier for any damage. Repair the damage before starting and operating
the scarifier.
7. Scarifier components, guards and shields are subject to wear and damage which could expose moving
parts or allow objects to be thrown. For safety protection, frequently check components and replace
immediately with original equipment manufacturers (O.E.M.) parts only, listed in this manual. “Use of
parts which do not meet the original equipment specifications may lead to improper performance and
compromise safety!”
8. Do not change the engine’s governor setting or over-speed the engine. The governor controls the
maximum safe operating speed of the engine.
9. Check fuel line, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
10. Do not crank engine with spark plug removed.
11. Maintain or replace safety and instruction labels, as necessary.
12. Observe proper disposal laws and regulations. Improper disposal of fluids and materials can harm the
environment.
DO NOT MODIFY THE ENGINE
To avoid serious injury or death, do not modify the engine in any way. Tampering with the governor setting
can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory setting of
engine governor. Please refer to the Briggs & Stratton engine manual, before undertaken any inspection,
repair or maintenance.

KNOW YOUR MACHINE
* Image may vary from actual machine
The lawn scarifier is pushed by hand over the area of grass to be cut. The cutters are driven by a petrol engine.
The depth of cut is set by varying the central height-adjustment mechanism individually.
AERATOR: The cylinder rotates and removes the felt layer formed by moss, lichen and weeds and conveys the
scarified material to the outside or into the grass catcher. During cutting the cutters penetrate the ground and
therefore ensure that the lawn is loosened and absorbs nutrients better. We recommend dethatching the lawn
in spring (April/May) and autumn (October).
SCARIFIER: The cylinder rotates and combs the lawn or aerates the slightly mossy areas. The removed moss is
conveyed outwards or into the grass catcher. During aeration, the surface of the ground is scratched; this
improves water drainage and facilitates the absorption of oxygen. We recommend scarifying the lawn during
the entire growing period as and when required.

PRE-OPERATION
FUEL & OIL
WARNING
YOUR MACHINE IS SUPPLIED WITHOUT ENGINE OIL OR UNLEADED PETROL
Operating the engine with insufficient oil can have catastrophic consequences. Any failure caused by
insufficient oil, will not be covered by the manufacturer’s warranty.
Read instructions carefully.
Fuel & its vapors are very flammable. Do not use or fuel the machine near a flame, sparks or while smoking.
Allow the engine to cool for more than 3 minutes, before re-fueling. Never fuel the machine with the engine
running. Fuel the engine at least 15 metres away from your work area. Always fuel your machine outdoors.
IMPORTANT:
Fuel which is older than 30 days old can become stale and cause acid & gum deposits in the fuel system or
essential carburettor components. This could result in starting issues which would not be covered by the
manufacturer’s warranty.
Ensure that any stored petrol is clearly marked in a separate appropriate canister for a maximum of 30 days
if not mixed with a fuel additive. If the machine is not going to be used for a long period, drain the petrol
from the fuel tank, start the engine and drain the carburetor of any remaining fuel.
To keep fuel fresh, refer to instructions from the engine manual supplied with this machine. A fuel additive
which you add to your fuel, can help make your machine easier to start, extend the shelf life of your fuel for up
to two years, keeping the carburettor & engine clean, plus reducing emissions and increasing fuel economy.
