7. Pull starter rope again while trigger is in the full throttle position until engine starts. (Fig. 9F)
8. Once engine is started, leave the choke lever in the
HALF CHOKE “ ” position for 20 seconds, then move choke lever to RUN “ ”. (Fig. 9H)
If engine does not start, go back to step 2.
NOTE: If engine fails to start after repeated attempts, refer to Troubleshooting section.
NOTE: Always pull starter rope straight out. Pulling starter at an angle will cause rope to rub against the eyelet. This friction will cause the rope to fray and wear more quickly.
Always hold starter handle when rope retracts. Never allow rope to snap back from extended position. This could cause rope to snag or fray and also damage the starter assembly.

TRIMMER INSTRUCTIONS
• OPERATING INSTRUCTIONS FOR USE
WITH TRIMMER HEAD
WARNING:
Always wear eye protection. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury.
Before trimming, bring engine to a speed sufficient to cut material to be trimmed.
When cutting grass, engine RPM should be maintained at a level where the trimmer line cuts grass cleanly without overloading or slowing the engine.
Always release the throttle trigger and allow the engine to return to idle speed when not cutting.
To stop engine:
-
Release the throttle trigger.
-
Push and hold the ON/STOP switch in the STOP
position until the engine stops.
• TRIMMER LINE ADVANCE
Advance line by tapping the bottom of the cutting head lightly on the ground while engine is running at full speed. The metal line limiter blade attached to the guard will cut the line to the proper length.
WARNING:
Use only 2,4 mm diameter line. Other sizes of line will not advance properly and will result in improper cutting head function or can cause serious injury. Do not use other materials such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury.
• CUTTING METHODS
WARNING:
Do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard.
-
The tip of the line does the cutting. You will achieve the best performance and minimum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below.
Tip of line does the cutting.
Line crowded into work area.
GB
- The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences.
- For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially:
- During light duty cutting.
- Near objects around which the line can
wrap such as small posts, trees or fence
wire.
- For mowing or sweeping, use full throttle for a good clean job.
TRIMMING - Hold the bottom of the trimmer head about
8 cm above the ground and at an angle. Allow only the tip of the line to make contact. Do not force trimmer line into work area.
Trimming
8 cm above ground
SCALPING - The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 8 cm above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line wear.
Scalping
MOWING - Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool.

SWEEPING - The fanning action of the rotating line can be used to blow away loose debris from an area. Keep the line parallel to and above the area surface and swing the tool from side to side.
Sweeping
GB unit. The uncontrolled unit can cause serious injury if the blade contacts the operator or others.
•
WHEN BLADE THRUST OCCURS - Blade Thrust can 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. By using the unit properly, the occurrence of blade thrust will be reduced and the operator will be less likely to lose control.
• TRIMMING PROCEDURES
When properly equipped with a cutting attachment guard and cutting head, your unit will trim unsightly weeds and tall grass in those hard-to-reach areas - along fences, walls, foundations and around trees. It can also be used for scalping to remove vegetation down to the ground for easier preparation of a garden or to clean out a particular area.
NOTE: Even with care, trimming around foundations, brick or stone walls, curves, etc., will result in above normal string wear.
TRIMMING / MOWING
Swing trimmer with a sickle-like motion from side to side.
Do not tilt the cutting head during the procedure.Test area to be trimmed for proper cutting height. Keep cutting head at same level for even depth of cut (Fig. 12A).

OPERATING INSTRUCTIONS FOR USE WITH
WEED BLADE
•
Blade Thrust is a reaction that only occurs when using a bladed unit. This reaction can cause serious injury. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce the chance of its occurring, and how you can remain in control of unit if blade thrust occurs.
•
WHAT CAUSES BLADE THRUST - Blade Thrust can occur when the spinning blade contacts an object that it does not cut. This contact causes the blade to stop for an instant and then suddenly move or “thrust” away from the object that was hit. The “thrusting” reaction can be violent enough to cause the operator to be propelled in any direction and lose control of the
11
•
Cut only grass, weeds, and woody brush up to 1 cm in diameter with the weed blade. Do not let the blade contact material it cannot cut such as stumps, rocks, fences,metal, etc., or clusters of hard, woody brush having a diameter greater than 1 cm.
•
Keep the blade sharp. A dull blade is more likely to snag and thrust.
•
Cut only at full throttle. The blade will have maximum cutting power and is less likely to bind or stall.
•
“Feed” the blade deliberately and not too rapidly. The blade can thrust away if it is fed too rapidly.
•
The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the cutting stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade do the cutting.
•
Use the shoulder strap and keep a firm grip on the unit with both hands. A properly adjusted shoulder strap will support the weight of the unit, freeing your arms and hands to control and guide the cutting motion.
•
Keep feet comfortably spread apart and braced for a possible sudden, rapid thrust of unit. Do not overreach. Keep firm footing and balance.
•
Keep blade below waist level; it will be easier to maintain control of unit.
•
Do not raise the engine above your waist as the blade can come dangerously close to your body.
•
Do not swing unit with such force that you are in danger of losing your balance.
Bring the engine to cutting speed before entering the material to be cut. If the blade does not turn when you squeeze the throttle trigger, make sure shaft is fully inserted into the engine.
Always release the throttle trigger and allow engine to return to idle speed when not cutting. The blade should not turn while the engine is running at idle. If the blade turns at idle, do not use your unit. Refer to the
CARBURETOR ADJUSTMENT section or contact your authorized service dealer.
•
Maintain good firm footing while using the unit. Do this by planting feet firmly in a comfortable apart position.
•
Cut while swinging the upper part of your body from right to left.
•
As you move forward to the next area to cut, be sure to maintain your balance and footing.
WARNING: The operator or others must not try to clear away cut material with the engine running or the blade turning to avoid serious injury. Stop engine and blade before removing materials wrapped around blade or shaft.

• BLADE REPLACEMENT
Refer to the ASSEMBLY section for blade replacement instructions and illustrations.
• CARBURETOR ADJUSTMENT
WARNING:
Keep others away when making idle speed adjustments. The trimmer head will be spinning during most of this procedure. Wear your protective equipment and observe all safety precautions. After making adjustments, the trimmer head must not move/spin at idle speed. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions:
-
Engine will not idle when the throttle is released.
-
The trimmer head moves/spins at idle speed.
Make adjustments with the unit supported so the cutting attachment is off the ground and will not make contact with any object. Hold the unit by hand while running and making adjustments. Keep all parts of your body away from the cutting attachment and muffler.
Idle Speed Adjustment
Allow engine to idle. Adjust speed until engine runs without trimmer head moving or spinning (idle speed too fast) or engine stalling (idle speed too slow).
- Turn idle speed screw clockwise to increase engine speed if engine stalls or dies.
-
Turn idle speed screw counterclockwise to decrease engine speed if trimmer head moves or spins at idle speed.
WARNING:
Recheck the idle speed after each adjustment. The trimmer head must not move or spin at idle speed to avoid serious injury to the operator or others.
