WARNING: Alcohol-enriched fuels (gasohol) or fuels with
ethyl alcohol or methanol mixtures may attract humidity and
subsequent acid formation. The clean petrol may as a result
of long storage damage the engine fuel system. If you want
to prevent engine problems you should empty the fuel
system before storing for more than 30 days. Empty the fuel
tank, start the engine and let it run until the fuel system and
carburettor are empty. Add fresh fuel each season. See the
storing instructions, too. Never pour cleaners to the fuel tank
to clean the engine or carburettor. By doing so, you could
cause irreparable engine damage.

Important tips and advice for grass cutting!!!
• Under certain conditions, e.g. when the grass is very high, it
may be necessary to adjust bigger cutting height so that effort
at pushing the mower was reduced, engine overloading
removed and blocking of grass in the mower prevented. It is
possible you will also have to reduce the mower travel speed
and/or cut the area again.
• If cutting is very difficult it may be suitable to reduce the travel
speed and mower gear.
Picture for engine starting
• Vent ports in the grass catcher may get blocked if the catcher
is not cleaned regularly. Clean the grass catcher regularly with
water and let it dry before use.
• Keep the upper part of the engine in the
starter place clean. Air flow will be improved
and engine life increased by doing so.
Cut in dry weather only.
•
Always keep the knives sharp.

MAINTENANCE
IMPORTANT – Regular maintenance is unavoidable for
constant operational reliability and keeping the original
device output.
1) Keep all screws and nuts tightened so that you were sure
the device is in an operation-reliable condition. Regular
maintenance is necessary for safety and trouble-free
operation.
2) Never store the device with fuel in closed rooms as the
evaporating fuel may ignite.
3) It is necessary to let the device cool down and empty fuel
from it before storing in closed rooms.
4) In order to minimise the risk of fire keep the engine
and muffler and the fuel tank clean and with no grass,
leaves and fats. Do not store the grass cut with the
mower.
5) For safety reasons, avoid using a device with a worn
or damaged parts. Replace any faulty parts with new
ones, do not repair them. Use original spare parts and
original spare knives only.

may damage the device and threaten your safety.
6) If it is necessary to empty the fuel tank do it outside and
with cold engine.
7) Wear solid protective gloves at assembly and adjustment
of knives.
8) Check correct direction of rotating and balance of knives
after sharpening.
9) Regularly check wear and pollution of the self-closing
cover and grass catcher.
10) When you must transport the device, carry it in hands or
incline it always wear safety gloves.
Always hold the device at places guaranteeing safe holding.

ČLEANING
Clean the device with water, remove the grass and mud from
inside before each use – it will prevent from impurities getting dry
and problems at next starting.
The painting inside the housing may wear down in the course
of time. In order to prevent later corrosion of the device use
anti-corrosive paint for the worn-down spots.
Remove the gearbox cover and clean the space around belt
pulleys and drive belts with a brush or compressed air once or
twice a year.
You should clean the inside of the drive wheels once per
season. Disassemble both wheels. Clean the cog wheels and
their edges off the grass and other impurities with compressed
air or a brush.
