Operation
Before Starting the Lawnmower
Adding Oil
The lawnmower is supplied without motor oil. Before first start
up, add motor oil SAE30 or 15W-40 (approx. 600 ml)
according to the following instructions.
1. When pouring in the oil, place the lawnmower on a level
surface.
2. Pull the cap with the oil dipstick out of the oil refill hole.
3. After adding oil, put the dipstick back into the hole and
tighten it.
4. The oil level must be between the upper (MAX) and lower
(MIN) limit.
CAUTION! DO NOT OVERFILL the oil tank, otherwise a large amount of smoke will come out of the exhaust
when the lawnmower is started up.
IMPORTANT INFORMATION:
•
Check the oil level before every use of the lawnmower. Add oil if necessary. Add oil up to the MAX level
mark on the oil dipstick.
•
Replace the oil after the first 5 hours of operation and subsequently after every 25 hours of operation.
Adding Fuel
•
The suitable type of fuel for this engine is NATURAL 95.
•
After unscrewing the fuel tank cap, add the fuel, pouring it in all the way up to the collar of the fuel tank but
do not overfill it.
•
Always add fresh, clean and approved lead-free petrol with an octane rating of at least 95.
CAUTION!
•
In the event that you spill any oil or fuel on the lawnmower when refilling, wipe it away immediately. Do not
store or add fuel or handle it in any way in the vicinity of an open fi re.
•
Fuels mixed with alcohol or fuels with ethanol or methane additives may bind moisture to themselves, which
may result in separation during storage and the formation of acids. Subsequently during storage the acid
vapours may damage the fuel system of the lawnmower engine. These fuels must not be used in the
lawnmower.
IMPORTANT INFORMATION:
•
When not using the lawnmower for longer than 30 days, drain the fuel tank, start the engine and let it run
until the fuel lines and the carburettor are empty (the engine will stop on its own). This will prevent future
engine problems.
•
Before using it again, add fresh fuel into the fuel tank. For more information, see chapter Storage
instructions.

Controlling and Operating the Lawnmower
Starting the Lawnmower
1. Move throttle to COLD/START position.
2. Pull the STARTER CABLE. The cable must be given a short tug to engage the starter (approx. 3 – 5cm of
cable). Once engaged pull the remaining cable in 1 continuous and firm motion. Repeat 3 – 4 times in
succession or until engines starts.
3. When engine starts, move throttle to the RUN position. Keeping the throttle in the COLD/START position
may cause engine to stop or run poorly.
CAUTION! A small amount of smoke may be emitted when the engine is started up for the first time as the
protective layers in the engine are burnt off. This is completely normal and does not constitute a problem.

Controlling Travel
The travel is controlled using the travel lever. When the lever is pulled to the handle, the lawnmower will start
moving. To stop, release the lever. This lawnmower has one constant speed.
Application Range for the Petrol Lawnmower
•
Mowing with collection of grass clippings in a grass catcher.
•
Mowing with rear discharge of grass clippings.
•
Mowing with side discharge.
•
Mulching - mowing with loose placement of grass clippings on the lawn.
Mowing With the Grass Catcher
When the grass catcher is installed, grass clippings are discharged into the grass catcher.
Mowing with Rear Discharge
Without the grass catcher installed, the grass catcher cover serves as a deflector that directs the movement of
the grass clippings towards the ground. A row of grass clippings is thereby formed behind the lawnmower.
Mowing with Side Discharge
CAUTION! Attach and remove the side discharge deflector only with the engine turned off.
Use your hand to lift the side discharge cover and attach the side discharge deflector. In order to mow with side
discharge, it is necessary to install a mulching plug into the discharge chute.

Setting the Mowing Height
The mowing height is set centrally using the central mowing height adjustment lever. You can select from 5
positions in the range of 25 to 70 mm. The middle mowing height is the most suitable for the majority of lawns.
Lawn damage may result when the lowest height is set.
Replacing the Mowing Blades
CAUTION! For this task, we recommend that you contact an authorised service centre. Prior to removing the
blade, drain the oil from the oil tank.
If you wish to replace the mowing blade, remove the bolt. Perform the installation according to the provided
picture below. Tighten the screw. The tightening torque is 40 Nm. When replacing the blade, replace the
fastening bolt also.
Changing the Motor Oil
CAUTION! For this task, we recommend that you contact an authorised service centre.
1. The drain plug is located under the engine. Place a suitable
container for catching the used oil under the engine and
remove the plug. Tilt the lawnmower so that all the oil can
drain from the oil tank.
2. After draining the oil, put the plug back into the hole, making
sure that the plug is securely in its place and wipe away any
drops of spilled oil.
3. Add type SAE30 or 15W-40 oil into the oil tank.
4. When the oil dipstick is inserted into the hole and screwed
in, the oil level should be between the Min and Max marks.
Do not overfill the oil tank.
5. Start the engine and allow it to run for a short time.
6. Stop the engine, wait 1 minute and re-measure the oil level
in the oil tank. Add oil to the required level if necessary.

Maintenance
Lawn Care
•
Various forms of care are required depending on the type of grass area.
•
Therefore, always read the instructions included on seed packages with respect to the mowing height for the
growing conditions in the given locality.
•
It is necessary to always keep in mind that the larger part of grass consists of a stem and one or more
leaves.
•
When the leaves are cut off completely, the lawn is damaged and the renewal of growth will be much more
difficult.
•
The following instructions generally apply:
−
Excessively low mowing causes disruption to the roots and subsequently “spotty” appearance;
−
In summer, mowing must be higher to prevent the soil from drying out;
−
Mowing wet grass may result in a lower efficiency of the blade due to grass catching on the blade and
grass being ripped out of the ground;
−
In the event of exceptionally tall grass it is appropriate to perform the first mow at the maximum permitted
mowing height of the machine and then mow again only after two or three days.
•
The lawn will have a better appearance when it is mowed regularly over its entire area at the same height
with alternating mowing directions.
Lawnmower Maintenance
•
All nuts, pins and bolts must be properly tightened so that the machine is in a safe and operational condition.
Regular maintenance is the basic prerequisite for ensuring safety of the user, maintain the lawnmower’s
operating condition and high performance.
•
Never store a machine with petrol in the fuel tank inside a building where the fumes could come within range
of an open fire, sparks or sources of high temperature.
•
Before storing in any enclosed area, allow the engine to cool down.
•
To reduce the risk of a fire, ensure that the lawnmower and in particular the engine, exhaust muffler, battery
and also the location of spare fuel storage are free of grass, leaves or excessive amounts of lubricant.
•
Regularly inspect the condition of the deflector and the grass catcher; replace if damaged.
•
Drain the fuel in a well ventilated area when the engine has cooled down.
•
When removing or installing the mowing blade, use thick work gloves.
•
It is necessary to check the balance of the mowing blade every time that it is sharpened.
•
ATTENTION: Before carrying out maintenance or repairs, stop the engine and disconnect the spark plug.
•
Regularly inspect the lawnmower and ensure that all grass deposits are removed from the underside of the
chassis.
•
Regularly lubricate the axle of the chassis and the bearings using a suitable lubricant.
•
Regularly inspect the condition of the blades because they have a significant effect on the performance of
the lawnmower. Blades should always be sharp and balanced.
•
In regular intervals, check that all nuts and bolts are tightened. Nuts and bolts that are worn out or incorrectly
tightened may cause serious damage to the engine or the frame.

Self-Propelled Lawnmower

•
If the blade strongly impacts an obstacle, stop the lawnmower and take it to an authorised service centre.
•
BLADE: the blade is made from pressed steel. To achieve the best possible mowing results, regularly
sharpen the blades, approximately after every 25 hours of operation. Check that the blade is always
correctly balanced. To do this, insert a steel axle (with a diameter of 2-3 mm) into the middle hole. If it is
correctly levelled, the axis will remain in the horizontal position.
•
If the blade does not remain in the horizontal position, replace it.
•
When removing the blade, screw out the bolt, check the load bearing part of the blade. If the parts are worn
out or damaged, replace them.
•
ATTENTION: Always use only original spare parts. Poor quality spare parts may cause serious damage to
the lawnmower and create a safety hazard.
