Cleaning the unit

Caution

Always keep the unit and venti-

lation slots clean and free of dirt.

Use a small brush for cleaning 

the outside of the unit.

Do not use abrasive detergents. 

Household cleaners which contain 

aromatic oils such as pine oil 

or lemon as well as solvents 

such as kerosene may damage 

the plastic housing and handle. 

Wipe housing with a damp cloth 

only.

Storage

Never store the unit with fuel 

in the tank or in a location where 

petrol vapours may be ignited 

by a spark or naked flame.

Before storing the unit, leave 

the engine to cool down.

Store the unit in a dry, closed 

room to prevent unauthorised 

use or damage. 

Keep the unit away from children.

Long-term storage

If the unit is to be stored for a pro-

longed period, proceed as follows:

Drain all the fuel out of the tank 

and pour into a container with 

the same two-stroke mixture. 

Do not use fuel which has been 

stored for longer than 3 days.

Start the engine and leave 

running until it stops. 

This ensures that there is no fuel 

left in the carburettor.

Leave the engine to cool down. 

Take out the spark plug and pour 

30 ml of a high-grade engine oil 

or two-stroke oil into the cylinder. 

Slowly pull the starter rope 

to distribute the oil. 

Reinstall the spark plug.

Note 

Take out the spark plug and pour 

all the oil out of the cylinder before 

starting the unit after storage.

Thoroughly clean the unit and 

check for loose and damaged 

parts. 

Repair or replace damaged parts 

and tighten loose screws, nuts 

and bolts. 

The unit can now be stored.

Store the unit in a dry, closed 

room to prevent unauthorised 

use or damage. 

Keep the unit away from children.

Transportation

Before transporting the unit, 

leave it to cool down.

Empty the fuel tank before trans-

porting the unit. 

Tank cap must be closed tightly.

Secure the unit to prevent it from 

shifting during transportation.

by our company or the importer 

are valid in all countries.

with the warranty, provided the fault

the warranty, please contact your
