3.2 Preparation
a) Never allow people unfamiliar with these instructions or children to use the machine. Local
regulations can restrict the age of the operator;
b) never operate the machine while people, especially children, or pets are nearby;
c) operators should take care to prevent accidents to themselves or other people and damage to
property;
d) wear ear protection and safety glasses at all times while operating the machine;
e) while operating the machine, always wear substantial footwear and long trousers. Do not operate the
machine when barefoot or wearing open sandals;

Tips for proper working
It is recommended that you overlap scarifying paths a little. Try to scarify in straight lines for
a nice, clean look. Insodoing, the aeration swaths should always overlap each other by a
few centimeters in order to avoid bare strips.
As soon as grass clippings start to trail the scarifiers, it is time to empty the grass basket.
Important!
Before taking off the grass basket, switch off the motor and wait until the roller has come to
a stop.
To remove the grass basket, lift up the ejector flap with one hand, while unhooking the
basket with the other.
How frequently you should scarify your lawn is determined primarily by the speed at which
the grass grows and the hardness of the soil.
Keep the underside of the equipment clean and remove soil and grass build-up. Deposits
make it more difficult to start the aerator and decrease the quality of the scarifying.
Always scarify along inclines (not up and down). Switch off the motor before doing any
checks on the roller.
Important!
The roller rotates for a few seconds after the motor is switched off. Never attempt to stop
the roller. In the event that the rotating roller strikes an object, immediately switch off the
equipment and wait for the roller to come to a complete stop. Then inspect the condition of
the roller. Replace any parts that are damaged.
9.Cleaning,maintenance,storage,transportandorderingofspareparts
Important!
Never work on or touch conducting parts on the ignition unit with the engine running.
Always pull the spark plug boot from the spark plug before starting any work of care or
maintenance. Never perform any work on the machine while it is run- ning. Any work not
described in these Operating Instructions must be performed by an authorized service
workshop only.
9.1Cleaning
The scarifier should be cleaned thoroughly every time after it has been used. This
particularly applies to its underside and the blades. To do so tip the scarifier slightly on to its
side and remove the dirt.
Important. Before you tip the equipment, the fuel tank must be emptied to prevent petrol
leaking out. Ideally you should use a conventional petrol extraction pump for this purpose.
9.2Servicing
Checkingtheoillevel
Set the equipment down on a flat, level surface.
Unscrew the oil dipstick by turning it anti-clockwise. The oil level must be as shown in
Figure 10.

Checking the oil level
Set the equipment down on a flat, level surface. Unscrew the oil dipstick by turning it anti-clockwise.
The oil level must be as shown in page 8 - Figure 10.
Oil
Oil Recommendations
• We recommend the use of our Warranty Certied oils for best performance. Other high-quality
detergent oils are acceptable if classied for service SF, SG, SH. SJ or higher.
• Do not use special additives.
• Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select
the best viscosity for the outdoor temperature range expected.
Note : Below 40°F (4 °C ) the use of SAE 30 will result in hard starting.
Above 80°F (27 ° C) t he use of 10W-30 may cause increased oil consumption.
Check oil level more frequently.
Before adding or checking the oil
• Place engine level.
• Clean the oil ll area of any debris.
/ŵƉŽƌƚĂŶƚ
Never run the engine with no or too little oil. This can cause serious damage to the engine.
Changingtheoil
a) Change the engine oil every year before the start of the season (in addition to the
informa- tion in the petrol service manual) when the engine is warm.
b) Use only recommended engine oil.
c) Place a suitable oil drip tray beneath the oil drain screw.
d) Remove the oil filler screw (Fig. 9 / Item A).
e) Undo the oil drain screw (Fig. 9 / Item B) and drain the oil into a suitable container.
f) Close the drain screw again when all the used oil has been drained.
g) Pour engine oil into the equipment as shown in page 8 - Figure 10.
h) Dispose of the used oil in accordance with applicable regulations.
Careandadjustmentofthecables
Oil the cables at regular intervals and check that they move easily.
Servicingtheairfilter
Soiled air filters reduce the engine output by supply too little air to the carburetor. Regular checks
are therefore essential. The air filter should be checked every 8 hours of use and cleaned if
necessary and replaced after 50 hours. If the air contains a lot of dust, the air filter should be
checked more frequently.
a) Remove the air filter as shown in Fig. 11-13.
b) Clean the air filter only by tapping it.
c) Assemble in reverse order
Important!
Never clean the air filter with petrol or inflammable solvents.
Servicing/Replacingthesparkplug
Check the spark plug for dirt and grime after 10 hours of operation and if necessary clean it with a
copper wire brush. Thereafter service the spark plug after every 50 hours of operation.
a) Pull off the spark plug boot (Fig. 14) with a twist.
b) Remove the spark plug using a spark plug wrench (Fig. 15).
c) Assemble in reverse order.
9.3Preparingtheequipmentforstorage
Caution
Do not empty the petrol tank in enclosed areas, near fire or when smoking. Petrol fumes can
cause explosions and fire.
a) Empty the petrol tank with a petrol suction pump.
b) Start the engine and let it run until any remai- ning petrol has been used up.
c) Change the oil at the end of every season. To do so, remove the used engine oil from a
warm engine and refill with fresh oil.
d) Remove the spark plug from the cylinder head. Fill the cylinder with approx. 20 ml of oil
from an oil can. Slowly pull back the starter handle, which will bathe the cylinder wall
with oil. Screw the spark plug back in.
e) Clean the cooling fins of the cylinder and the housing.
f) Be sure to clean the entire machine to protect the paint.
g) Store the machine in a well-ventilated place.
14
9.4Preparingthedevicefortransport
a) Drain the petrol tank using a petrol extraction pump.
b) Always let the engine run until it has used up the remainder of petrol in the tank.
c) Empty the engine oil from the warm engine.
d) Remove the spark plug boot from the spark plug.
e) Clean the cooling fins of the cylinder and the housing.
f) Remove the push bars if necessary. Ensure that the cables are not kinked.
9.5Orderingreplacementparts
Please quote the following data when ordering replacement parts:
a) Type of machine
b) Article number of the machine
c) Identification number of the machine
d) Replacement part number of the part required ( For our latest prices and
information please go to www.mticanada.ca )
