Check the terrain where you are going to use the machine, and remove any objects that
could be caught, tangled, or discarded (stones, shards of glass, nails, wires, toys, sticks, etc.).
Only operate the machine on a safe surface and only in good light!
Never use the machine during rain and storms, especially if there is a risk of lightning strikes.
Never use the machine on a slippery surface. Keep children and bystanders away while
operating the machine. Distractions can cause you to lose control.
Be careful when using the lawnmower near verges, ditches, or banks. Machine can suddenly
turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.
WORKING ON SLOPES
Do not mow excessively steep slopes. Danger of injury by overturning machine. Maximum
allowed slope is 15°.
For wheeled rotary machines, mow across the face of slopes, never up and down.
Exercise extreme caution when changing direction on slopes.

USING PETROL MACHINES

When working with a petrol machine never use brute force. The machine, which was
designed for the job, performs it better and safer, therefore always use the correct machine
for a given task.
The performance of a petrol engine mounted on a particular device, may not achieve gross
output. It is caused by many factors, e.g. the used components (exhaust, charging, cooling,
carburettor, air filter, etc.), usage restrictions, operational conditions of use (temperature,
humidity, etc.) and the differences between individual engines produced.

ENGINE OPERATION

B
WARNING!
Engine produces carbon monoxide during operation. It is a colourless, odourless
poisonous gas. Breathing carbon monoxide can cause nausea, faintness, reproductive
disorders or even death.
Do not start the engine in a closed space which can cause an accumulation of carbon
monoxide.
A
CAUTION!
A running engines generates heat. Parts of the engine and silencer become extremely
hot during operation. After touching they may cause serious burns. If it is close to
any flammable materials, e.g. leaves, grass, shrubbery etc., it may catch fire.
