2. Remove the carburetor fuel sediment cup with
its rubber seal ring.

FUEL FILTER
The fuel tank may be fitted with a filter, depend­
ing on tiller model, situated at the fuel tank cap.
The fuel filter can be picked out and should be
checked periodically. If the filter is dirty, clean it
and replace it with a new one when required. In
case the inside of the fuel tank is dirty, it can be
cleaned by rinsing the fuel tank with clean petrol.
CLEANING
Use a small soft brush to clean the outside of the
unit. Do not use strong detergents. Household
cleaners that contain aromatic oils such as pine
and lemon and solvents such as kerosene can
damage plastic housing or handle. Wipe off any
moisture with a soft cloth.
STORAGE
WARNING
Never store the unit with fuel in the tank and always
allow the unit to cool before storing. Store the unit
only in dry and well ventilated areas.
In case the unit will be stored for an extended
time, use the following storage procedure:
1. Drain all fuel from the fuel tank.
2. Start the engine and allow it to run until it
stalls. This ensures that all the fuel has been
drained from the carburetor.
3. Replace the engine oil with new.
4. Replace the gearbox oil with new.
5. Replace the air filter oil with new, if the air filter
is oil bath type.
6. Remove the spark plug and put 30 ml of high
quality motor oil into the cylinder. Pull the
starter rope slowly to distribute the oil. Rein ­
stall the spark plug.
7. Thoroughly clean the unit and inspect for any
loose or damaged parts. Repair or replace dam ­
aged parts and tighten loose screws, nuts or
bolts.
8. Lubricate all parts required with an oil damp
cloth to avoid rust built­up.
ENVIRONMENTAL PROTECTION
Recycle raw materials instead of disposing as
waste. Machine, accessories and packaging should
be sorted for environment friendly recycling. The
plastic components are labeled for categorized
recycling.
Dispose used motor oil and the containers in a

We suggest you take it in a sealed container to
