ASTARTING A WARM ENGINE

Position the on/off switch to the I (ON) position. Squeeze the primer bulb (C) several times until you see fuel begin to return back through tube (D) to the fuel tank. Push the decompression valve (B) down if your model is fitted with one. Pull the starter handle until the engine runs.

5)STOPPING THE ENGINE

Push the on/off switch to the STOP position.

WARNING: After the engine has been switched off, the rotating cutting attachment, blade or string head, will continue to rotate for a few seconds due to their inertia. Continue to hold the machine firmly off the ground until it stops completely. Keep your hands away whilst

it is moving.

N.B. In an emergency, the cutting attachment can be stopped quickly by touching it parallel to the ground after moving the switch to the «STOP» position.

L.CARBURETTORADJUSTMENT

To adjust the idle speed, however, proceed as follows:

With engine running and warm, slowly turn screw ‘T’ clockwise until the engine runs smoothly with a consistent noise level but without making the cutting head rotate.

If the cutting attachment does move or the engine runs too fast, slowly turn screw ‘T’ in an anticlockwise direction until the correct speed is obtained.

Precise numerical engine speed settings are mentioned in the technical detail chart in the front of the owner’s manual.

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.

N.B. Slide the air filter back into its location (C) ensuring the tabs (A) are pointing downwards as illustrated, ensure it clicks firmly into its airtight position.

2)Every 50 working hours inject the gearcase with gear grease under high pressure through hole (C).

3)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 wrong fuel mixture (too much oil in the petrol) or a poor quality of oil in the fuel mix. Check and correct.

4)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.
