Regular maintenance
8. REGULAR 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 fi re, sparks or sources of high temperature
Before storing in any enclosed area, allow the engine to cool down.
To reduce the risk of a fi re, ensure that the lawnmower and in particular the engine, exhaust muffl er, 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 defl ector 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.
Before using the four-stroke engine, please carefully read the user's manual of the engine. Regularly check the
oil level and if necessary add oil or change it.
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 signifi cant 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.
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.
