Residual risks
Even if you use this product in compliance with all safety requirements, the potential risks of injury
and damage remain. The following hazards may arise in the structure and design of this product:
There are risks of injury and property damage due to attachments or broken the sudden impact of
hidden objects when using cutting.
There are risks of injuries and accidents caused by flying objects.
Prolonged use of this product exposes the operator to vibrations and can produce so-called "white
finger" disease. To reduce the risk, wear gloves and keep your hands warm.
If any of the symptoms of "white finger syndrome" occur, seek immediate medical attention.
Symptoms of "white finger" include numbness, loss of sensitivity, tingling, pain, loss of strength,
colour changes or skin condition. These symptoms usually appear on the fingers, hands or wrists.
Risk increases at low temperatures.
A long exposition to noise can affect the health of the operator. A hearing protection must be
always used when operating the tool. The operation of the tool must be limited and some rest
must be taken between two sessions (e.g. 10min of operation and 20min of rest).

ADJUST CUTTING HEIGHT
Raise wheels for low cut and lower wheels for deepcut, adjust cutting height to suit your
requirements. Medium position is best for most lawns.
BEFORE STARTING ENGINE ADD OIL
Before each subsequent use the oil level must be check and if necessary topped up with500ml
SAE30 engine oil.
OIL FILLER CAP/DIPSTICK
Your lawnmower is shipped without oil in the engine. For type and grade of oil to use,
Please use 15W-40.
CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler on
startup.
1.Be sure lawnmower is level.
2.Remove oil dipstick from oil fill spout.
3.Insert and tighten dipstick.

12
IMPORTANT:
•Check oil level before each use. Add oil if needed. Fill to full line on dipstick.
•Change the oil after every 25 hours of operation or each season. You may need to
change the oil more often under dusty, dirty conditions. See "TO CHANGE ENGINE OIL" in
the Maintenance section of this manual.
ADD GASOLINE
•Fill fuel tank to bottom of tank filler neck Do not overfill. Use fresh, clean, regular unleaded
gasoline. Do not mix oil with fuel in quantities that can be used within 30 days to assure
fuel freshne.
CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open
flame.
1) Keep all nuts, bolts and screws tight to be sure the equipment is in safe working
condition. Regular maintenance is essential for safety and performance.
CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methan can attract
moisture which leads to separation and for mation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage. To avoid engine problems, the fuel
system should be emptied before storage of 30 days or longer. Empty the gas tank, start the
engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.
See Storage Instructions for additional information. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.
START ENGINE
To start the engine, first make sure that the spark plug and that the machine is filled with
sufficient oil and petrol.
NOTE: Due to protective coatings on the engine, a small amount of smoke may be present
during the initial use of the product and should be considered normal.
Hold operator presence control bar down to the handle and pull starter handle quickly.
Do not allow starter rope to snap back.
NOTE: In cooler weather it may be necessary to repeat priming steps.

13
STOP ENGINE
•To stop engine, release operator presence control bar.
WARNING ! The blade will continue to rotate for a few seconds after the engine has
stopped. Disconnect the spark plug cap if the lawnmower is to be left unattended.
MOWING TIPS
•Under certain conditions, such as very tall grass, it may be necessary to raise the height of
cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of
grass clippings. It may also be necessary to reduce ground speed and/or run the lawn
mower over the area a second time.
•For extremely heavy cutting, reduce the width of cut by over lapping previously cut path
and mow slowly.
•Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will
collect less grass. To prevent this, regularly hose catcher off with water and let dry before
using.
•Keep top of engine around starter clear and clean of grass clippings and chaff. This will
help engine air flow and extend engine life.
6) MAINTENANCE
IMPORTANT - Regular, careful maintenance is essential for keeping the safety level and
original
performance of the machine unchanged in time.
2) Never store the equipment with fuel in the tank inside a building where vapour may reach a
flame or a spark or a source of extreme heat.
3) Allow the engine to cool before storing in an enclosed space.
4) To reduce the fire hazard, keep the engine; exhaust silencer, battery compartment and
fuel storage area free of grass, leaves, or excessive grease. Do not leave containers
with grass cuttings in rooms.
5) Replace worn or damaged parts for safety For reasons of safety, do not use the
equipment with worn or damaged parts. Parts are to be replaced and not repaired. Use
genuine spare parts (blades should always with the symbol JOYER 111003).Parts that
are not of the same quality can damage the equipment and be dangerous for your
safety.
6) If the fuel tank has to be drained, this should be done outdoors and when the engine is
cool.
7) Wear strong work gloves when removing and reassembling the blade.
8) Check the blade's balance after sharpening.
9) Check the self-closing guard and grass-catcher frequently for wear and deterioration.

14
10) Whenever the machine is to be handled, transported or tilted you must:
-wear strong working gloves;
-grasp the machine at the points that offer a safe grip, taking account of the weight and its
distribution.
CLEANING
Carefully clean the machines with water after each cut; remove the grass debris and mud
accumulated inside the chassis to avoid their drying and thus making the next start-up difficult.
The paintwork on the inside of the chassis may peel off in time due to the abrasive action of the
cut grass; in this case, intervene promptly by touching up the paintwork using a rustproof paint to
prevent the formation of rust that would lead to corrosion of the metal.
Remove the transmission casing by removing the screws and clean around the transmission
and drive belts with a brush or compressed air once or twice a year.Once every season, the
drive wheels should be cleaned internally. Remove both wheels. Clean the gear wheel and the
wheel gear rim of grass and dirt using a brush or air compressor.
CHANGING BLADES
To replace the blade, undo the screw. Empty the oil tank before removing the blade
Reinstall as illustrated. Tighten the screw properly. Tightening torque 40 Nm. When replacing the
blade, the blade screw should also be replaced
Changing the Oil
The oil drain plug is located under engine, have a container ready to catch the oil and remove
the drain plug. We should incline machine to make sure all the oil could be go out,Once the oil
has been emptied, replace the drain plug making sure that the washer is in place and wipe clean
any spillages.
Refill with SAE30 oil. When the dipstick is rested on the filler pipe (i.e. not screwed in place), the
oil lever must be between the Min and Max marks on the dipstick. Do not overfill.
Start the engine and allow it to run briefly. Stop the engine, wait one minute and check the oil
level. Top up if necessary.

15
Spark Plug
Once the engine has cooled, remove the spark plug using the box spanner supplied, clean
the plug with a wire brush. Using a feeler gauge, set the gap to 0.75 mm( 0.030"). Refit
the spark plug taking care not to overtighten.
Air Filter
Unclip the air filter cover and remove the sponge filter element. To avoid objects falling into
the air intake, replace the air filter cover.
DRAINING THE FUEL TANK AND CARBURETOR
1. Place an approved gasoline container below the carburetor, and use a funnel to avoid
spilling fuel.
2. Remove the drain bolt, then move the fuel valve lever to the ON position
3. After all the fuel has drained into the container, reinstall the drain bolt and washer. Tighten
the drain bolt securely.
