MAINTENANCE

To ensure a long service life and to avoid any damage to the brushcutter, perform the 

following maintenance at regular intervals.

Air Filter:

Check and clean the Air Filter regularly to ensure optimum performance.

Remove the air filter cover, take out the element and wash in lukewarm water.  Allow to 

dry completely and then replace. Clean off any excessive dirt and dust.

Fuel Filter:

Take the filter out of the fuelling port using a small wire hook. Disconnect the filter 

as

sembly from the fuel pipe and unhook the retainer to disass

e

mble it. Clean the 

compo

nents with petrol.

Spark Plug:

Check the spark plug periodically and ensure that the gap between the electrodes is 

between 0.6 and 0.7mm.  Adjust where necessary using the universal wrench supplied. 

If the spark plug is clogged with carbon, clean thoroughly or replace with an

NGK BM6A

or Champion CJ8

 after every

 25 hours

 of use

.

Idle Adjustment Screw:

If the blade continues to run on when you release the throttle lever or the engine stops, 

it may be necessary to adjust the Idle Adjustment Screw.

 it

 anti

Storage:

When storing the brushcutter for any length of time it is important to drain down the fuel, 

both in the tank and the carburettor. Either drain the fuel manually or run the engine 

until it uses up all the fuel.

Remove the spark plug and add a few drops of oil into the spark plug hole. 

Pull the starter cord gently to confirm that a film of oil covers the engine inside.

Tighten the spark plug.

Clean dirt or dust from the cutter blade and the outside of the 

machine and wipe with an oily cloth. Store in a dry place.
