A) Direct drive trimmers: The cutting head will

always rotate when engine is running.

B)All the above mentioned adjustments must be made with the relevant cutting attachment correctly fitted.

Warranty may be invalidated from incorrect carburettor adjustment made by persons other than an authorised dealer.

M.REGULARMAINTENANCE

From time to time ensure all screws are tight. Replace damaged, worn, cracked or warped blades. Always make sure nylon string head or blade have been assembled correctly (see sections NYLON STRING HEAD and BLADE ASSEMBLY) and blade fastener is tightened.

1)AIR FILTER CLEANING

(at least every 25 working hours).

A dust clogged air filter may cause carburetor problems.

This may prevent the engine from reaching its maximum speed and cause high fuel consumption and/or difficult starting.

Remove filter cover as shown in figure 1. Carefully clean the inside of filter box. The filter can also be cleaned with compressed air.

2)SPARK PLUG

From time to time (at least every 50 hours) remove and clean the spark plug and check the electrode gap (0,5/0,6 mm.). Replace

spark plug about every 100 working hours or whenever it is extremely encrusted. Heavily encrusted electrodes can result from an incorrect carburetor setting or from wrong fuel mixture (too much oil in the petrol) or a poor quality of oil in the fuel mix. Check and correct.

3)FUEL FILTER

To change fuel filter remove the tank cap and pull out the filter with a piece of bent wire or long forceps. Contact your Service Station for general servicing and cleaning of internal parts at least once a year.This will reduce the possibility of unexpected problems and will ensure maximum product life and efficiency.

REGULARLY: it is important, in order to avoid engine overheating, to remove dust and dirt from slots, gaps and from in between cylinder fins using a wooden scraper.

LONG STORAGE: empty fuel tank and run engine until dry.

Store trimmer in a dry place.
