OPERATION

 

■ It has been reported that vibrations from hand-held 

tools may contribute to a condition called Raynaud’s 

Syndrome in certain individuals. Symptoms may 

include tingling, numbness and blanching of the 

Fingers, usually apparent upon exposure to cold. 

Hereditary factors, exposure to cold and dampness, 

diet, smoking and work practices are all thought to 

contribute to the development of these symptoms. 

There are measures that can be taken by the operator 

to possibly reduce the effects of vibration:

 

■ Keep your body warm in cold weather. When operating 

the unit wear gloves to keep the hands and wrists 

warm. It is reported that cold weather is a major factor 

contributing to Raynaud’s Syndrome.

 

■ After each period of operation, exercise to increase 

blood circulation.

 

■ Take frequent work breaks. Limit the amount of 

exposure per day.

 

■ Injuries may be caused, or aggravated by prolonged 

use of a tool. When using any tool for prolonged 

periods, ensure you take regular breaks.

 

■ If you experience any of the symptoms of this 

condition, immediately discontinue use and see your 

doctor about these symptoms.

OPERATING AS A LINE TRIMMER (FIG.6)

Follow these steps to operate the straight shaft trimmer.

 

■ Start the trimmer.

 

■ Hold the trimmer at waist level with your right hand 

on the trigger handle and your left hand on the front 

handle.

■ Place the product on the right side of your body with 

the engine behind and away from your body.

 

■ Trim grass and weeds in a left-to-right motion with the 

line parallel to the ground.

TO ADVANCE THE CUTTING LINE (FIG.7)

Follow these steps to advance the cutting line.

 

■ Start the trimmer.

 

■ Tap the bump knob lightly on the ground while the 

motor is running. The line will only advance with the 

engine at full throttle. Do not hold the bump knob on 

the ground.

 

■ Do not bump the knob on hard surfaces such as 

concrete. This may cause damage to the bump knob.

Note:

 The line cutting blade on the safety guard will 

cut the line to the proper length.

Note: 

To help prevent line tangle, tap only once to 

lengthen the line. If additional line is required, wait a 

few seconds before retapping the bump knob. Do not 

allow the line to wear too short. Keep the cutting line 

at full length.

 

OPERATING AS A BRUSHCUTTER (FIG. 8-9)

 WARNING

Extreme care must be taken when using blades to 

ensure safe operation. Read the safety information for 

safe operation using the blade, refer to “Specific Safety 

Rules for Brushcutter and Blade Use” earlier in this 

manual.

TRI-ARC BLADE
The TRI-ARC blade is suited only for pulpy weeds and 

vines. When the blade becomes dull, it can be turned over 

to extend the life of the blade. Do not sharpen the TRI-

ARC blade.
Hold the brushcutter with the right hand on the trigger 

handle and the left hand on the front handle. Keep a firm 

grip with both hands while in operation. Brushcutter should 

be held at a comfortable position with the trigger handle 

about hip height. Maintain your grip and balance on both 

feet. Position yourself so that you will not be drawn off 

balance by the kick-back reaction of the cutting blade. If 

using a shoulder strap adjust to position the brushcutter 

at a comfortable operating position. Shoulder straps 

are available as an accessory and may help to reduce 

operator fatigue. 
Exercise extreme caution when using the blade with this 

unit. Blade thrust is the reaction which may occur when 

the spinning blade contacts anything it cannot cut. This 

contact may cause the blade to stop for an instant, and 

suddenly “thrust” the unit away from the object that was 

hit. This reaction can be violent enough to cause the 

operator to lose control of the unit. Blade thrust may occur 

without warning if the blade snags, stalls or binds. This is 

more likely to occur in areas where it is difficult to see the 

material being cut. For cutting ease and safety, approach 

the weeds being cut from the right to the left. In the event 

that an unexpected object or woody stock is encountered, 

this could cause the blade thrust reaction.

MAINTENANCE

 WARNING

When servicing, use only original manufacturer's 

 

replacement parts. Use of any other parts may create a 

hazard or cause product damage.

 WARNING

Always wear safety goggles or safety glasses with side 

shields during tool operation. If operation is dusty, also 

wear a dust mask.

 WARNING

Before inspecting, cleaning, or servicing the machine, 

shut off engine, wait for all moving parts to stop, and 

disconnect spark plug lead and move it away from 

spark plug. Failure to follow these instructions can 

result in serious personal injury or property damage.

 WARNING

Neglected or poorly conducted maintenance may 

create additional hazards. Do not attempt to repair or 

maintain this product if you are not qualified to do so. 

If in doubt, return to a service centre for professional 

assistance.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most 

plastics are susceptible to damage from various types of 

commercial solvents and may be damaged by their use. 

Use clean cloths to remove dirt, dust, lubricant, grease.

 WARNING

Do not at any time let brake fluids, petrol, petroleum-

based products, penetrating lubricants, etc., come 

in contact with plastic parts. Chemicals can damage, 

weaken or destroy plastic which may result in serious 

personal injury.

You can often make adjustments and repairs described in

this manual. For other repairs, have the trimmer serviced 

by an authorised service dealer.

CLEANING THE AIR FILTER (FIG. 11)

A  dirty  air  filter  will  cause  starting  difficulty,  loss  of 

performance, and shorten the life span of the engine. 

Check the air filter monthly. For best performance, replace 

the air filter at least once a year.

 

■ Loosen the air filter cover by turning the cover securing 

knob (item 22) counterclockwise.

 

■ Remove the air filter (item 20).

 

■ Clean the foam filter element with warm soapy water. 

Rinse and let dry.

 If the foam filter element is damaged, it should be 

replaced.

 

■ Apply a light coat of engine oil to the foam filter 

element, then squeeze it out.

 

■ Reinstall the air filter. 

NOTE:

 Make sure the filter is seated properly inside the 

cover. Installing the filter incorrectly will allow dirt to enter 

the engine, causing rapid engine wear. 

 

■ Reinstall the cover and tighten knob to secure.

CHECKING THE FUEL CAP

 WARNING

A leaking fuel cap is a fire hazard and must be replaced 

immediately.

The  fuel  cap  contains  a  non-serviceable  filter  and 

check  valve.  A  clogged  fuel  filter  causes  poor  engine 

performance. If performance improves when the fuel cap 

is loosened, the check valve may be faulty or the filter may 

be clogged. Replace the fuel cap if necessary.

REPLACING THE SPARK PLUG (FIG. 12)
