WORKING WITH WEED-CUTTING BLADES 
MOWING WEEDS 

Mowing means moving the blade in a horizontal curve 
from one side to the other. This is very effective for 
grass-like weeds and small undergrowth. It is not suit-
able for cutting large, tough weeds or woody vegeta-
tion. 

Do not use weed-cutting blades for cutting 
scrub or young trees! 

JAMMING 

Very thick vegetation, such as young trees or thick 
scrub may jam the blade and bring it to a standstill. 
Prevent the blade from jamming by anticipating the 
direction in which the scrub leans and cut it from the 
opposite side. 

If the blade jams while cutting, switch off the engine 
immediately. Hold the machine level so that the blade 
does not jump or break while you push the young tree 
away from the cut to free the blade. 

TO PREVENT RECOIL 

When using metal cutting tools (grass blades, thicket 
knives) there is a risk that the machine will recoil if the 
tool strikes a solid object (tree truck, branch, tree 
stump, stone or the like). In this case the machine will 
jump backwards in the opposite direction to which the 
tool is rotating. This may lead to a loss of control of the 
tool and risk of injury to the user and onlookers. 

Do not use metal cutting tools near fences, metal 
posts, boundary stones or foundations. 

The safety blade is designed to reduce recoil if the 
blade strikes a hard, solid object.

7 MAINTENANCE 

7.1 Air 

filter 

Never work without an air filter. Make sure it is 
always clean. If it is damaged then it must be 
replaced with a new filter. Empty the petrol 
tank and pour the fuel into a suitable jerry can. 
Open the petrol tank slowly so that any poten-
tial pressure can be released 

Cleaning the air filter: 

1. 

Unscrew the screw with which the air filter cover 
is secured; remove the cover and lift the filter out 
of the air inlet. 

2.  Wash the filter in soapy water. DO NOT USE 

ANY PETROL! 

3. 

Air-dry the filter. 

4. Re-insert 

the 

filter. 

PLEASE NOTE: Replace the filter if it is worn away, 
torn or damaged, or if it can no longer be cleaned. 

7.2 Carburettor 

adjustment 

The carburettor was pre-set at the factory for optimum 
performance. If further adjustments are necessary, 
please take your unit to the nearest Authorized Service 
Centre. 

7.3 Spark 

plug 

1. 

Spark plug gap = .025" (.635mm). 

2. 

Torque to 105 to 130 inch pounds (12 to 15 Nm). 
Connect spark plug boot.

7.4 

Debris shield knife sharpening 

1. 

Remove cutter knife from debris shield. 

2. 

Place knife in a bench vise. Sharpen knife using a 
flat file, being careful to maintain the angle of cut-
ting edge. File in one direction only

STORING A UNIT 

Failure to follow these steps may cause var-
nish to form in the carburettor and difficult 
starting or permanent damage following stor-
age 

1.  Perform all the general maintenance recom-

mended in the Maintenance Section of your User 
Manual. 

2. 

Clean exterior of engine, drive shaft assembly, 
debris shield and stringhead. 

3. 

Drain fuel from the fuel tank. 

4. 

After fuel is drained, start engine. 

5. 

Run engine at idle until unit stops. This will purge 
the carburettor of fuel. 

6. 

Allow engine to cool (approx. 5 minutes). 

7.  Using a spark plug wrench, remove the spark 

plug. 

8. 

Pour 1 teaspoon of clean 2-cycle oil into the com-
bustion chamber. Pull starter rope slowly several 
times to coat internal components. Replace spark 
plug. 

9. 

Store unit in a cool, dry place away from any 
source of ignition such as an oil burner, water 
heater, etc. 

10. 

Do not transport and store the trimmer with the 
blade fitted unless the supplied transport guard is 
also fitted

REMOVING A UNIT FROM 
STORAGE 

1. Remove 

spark 

plus. 

2. 

Pull starter rope briskly to clear excess oil from 
combustion chamber. 

3. 

Clean and gap spark plug or install a new spark 
plug with proper gap. 

4. 

Prepare unit for operation. 

5.  Fill fuel tank with proper fuel / oil mixture.
