SAFETY INSTRUCTIONS
The engine should be switched off when moving over 
ground that is not to be mowed. For example, gravel 
paths, stone, shingle, asphalt, etc.
The brake handle must never be permanently anchored in 
handle when the machine is running.
Follow the instructions above, but do not use a lawn mower in 
a situation where you cannot call for help in case of an 
accident.
Basic mowing technique
General
Mowing slopes can be dangerous. Do not use the lawn 
mower on very steep slopes.
The lawn mower should not be used on inclines greater 
than 30 degrees. 
On sloping ground you should work along the slope. It is 
much easier to work along a slope than it is to work up and 
down it.
Branches, twigs, stones, etc. should be removed from the 
lawn before you start to mow.
Never lift up the lawn mower or carry it around when the 
engine is running. If you must lift the lawn mower, first 
switch off the engine and disconnect the ignition lead from 
the spark plug.
Make sure the cutter does not hit foreign objects such as 
stones, roots or the like. This can make the cutter dull and 
bend the engine shaft. A bent axle gives imbalance and 
heavy vibration, which results in a great risk of the cutter 
becoming loose.
If any foreign object is hit or if vibrations occur stop the 
machine immediately. Disconnect the HT lead from the 
spark plug. Check that the machine is not damaged. 
Repair any damage.
Never mow more than 1/3 of the length of the grass. This 
especially applies during dry periods. Mow first with the 
cutting height set high. Then check the result and lower to 
an appropriate height. If the grass is really long, drive 
slowly and mow twice if necessary.
Never run with the machine when it is running. You should 
always walk with the lawn mower.
Use extreme caution when reversing or pulling the 
lawnmower towards you.
Cutting height
Shut down the engine before changing the cutting height.
The cutting height can be adjusted in five different steps, mm.
Do not set the cutting height too low as there is a risk that the 
cutters might hit slopes with unevenness.
Adjusting the cutting height
Shut down the engine before changing the cutting height.
Set the cutting height using the cutting height control on the 
right-hand side of the lawn mower.
To lower the cutting height move the lever to the right and 
then forward.
To raise the cutting height move the lever to the right and 
then backward.
Do not set the cutting height too low as there is a risk that the 
cutters might hit slopes with unevenness.
!
WARNING! Make sure that your hands and 
feet do not come near the cutting attachment 
when the engine is running.
