CARBURETTOR
ADJUSTMENT
Your machine may be fitted with a highly sensitive low emission carburettor. We now therefore recommend that carburettor adjustments are only made by an authorised servicing dealer, equipped with instruments that will ensure best performance with lowest emission levels.
To adjust the idle speed, however, proceed as follows:
With engine running and warm, slowly turn screw ‘I’ or ‘T’ clockwise until the engine runs smoothly with a consistent noise level but without making the chain or cutting head rotate.
If the cutting attachment does move or the engine runs too fast, slowly turn screw ‘I’ or ‘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.
NOTE:
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.

REGULAR
MAINTENANCE
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)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 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.
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.

REPLACING
NYLON
LINE
1)Unscrew the blocking screws at the bottom of the string head by turning them counter- clockwise.
2)Remove the base cover assembly.
Remove the empty spool from the housing and discard any remaining line.
REWINDING NEW LINE
3)Prepare 2 lengths (8ft each) of 2.4 mm nylon line. Thread 1 end of each line into the two holes on opposite sides of the spool. Pinch the exposed ends flat with a pair of pliers to prevent them slipping through the hole.
4)Wind the two lines in the same direction around the spool.
REASSEMBLY
5)Slide the end of the two lines into the grooves to hold the line temporarily.
6)Position the spool back into the housing and pull the line through the eyelets.
7)Pull about 12cm (5ins) of line out on either side.
8)Reassemble the string head as shown, tighten the screws clockwise.
9)N.B: In order to extend the nylon line as it wears down, pull the mower gauge downwards and turn it in a clockwise direction to feed out the desired length of line.
