OPERATING INSTRUCTIONS FORUSE WITH TRIMMER HEAD

WARNING: Always wear eye protec-tion. Never lean over the trimmer head. Rocksor debris can ricochet or be thrown into eyesand face and cause blindness or other seriousinjury.Before trimming, bringengine toa speedsuffi-cient to cut material to be trimmed.Do not run the engine at a higher speed thannecessary. The cutting line will cut efficientlywhen the engine is run at less than full throttle.At lower speeds, there is less engine noise andvibration. The cutting line will last longer andwillbe less likely to “weld” onto the spool.Always release the throttle trigger and allow theengine to return to idle speed when not cutting.To stop engine:S Release the throttle trigger.S Push and hold the ON/STOP switch in theSTOP position until the engine stops.

TRIMMER LINE ADVANCEAdvance line by tapping the bottomof the cut-ting head lightly on the groundwhile engine isrunning at full speed. The metal line limiterblade attached to the guard will cut the line tothe proper length.

WARNING: Use only 2,4 mm diame-ter line. Other sizes of line will not advanceproperly and will result in improper cuttinghead function or can cause serious injury. Donot use other materials such as wire, string,rope, etc. Wire can break off during cuttingand become a dangerous missile that cancause serious injury.CUTTING METHODS

WARNING: Useminimum speed anddo not crowd the line when cutting aroundhard objects (rock, gravel, fence posts, etc.),whichcandamage the trimmer head, becomeentangled in the line, or be thrown causing aserious hazard.S The tip of the line does the cutting. You willachieve the best performance and minimumline wear by not crowding the line into thecutting area. The right and wrong ways areshown below.

Right Wrong

Tip of line doesthe cutting.

Line crowded intowork area.

S The line will easily remove grass and weedsfrom around walls, fences, trees and flowerbeds, but it also can cut the tender bark oftrees or shrubs and scar fences.

S For trimming or scalping, use less than fullthrottle to increase line lifeand decreaseheadwear, especially:S During light duty cutting.S Near objects around which the line canwrap such as small posts, trees or fencewire.

S For mowing or sweeping, use full throttle for agood clean job.

TRIMMING -- Hold the bottom of the trimmerhead about 8 cm above the ground and at anangle. Allow only the tip of the line to makecontact. Do not force trimmer line into workarea.Trimming

8 cm aboveground

SCALPING -- The scalping technique re-moves unwanted vegetation down to theground. Hold the bottom of the trimmer headabout 8 cmabove the ground and at an angle.Allow the tip of the line to strike the groundaround trees, posts, monuments, etc. Thistechnique increases line wear.Scalping

MOWING -- Your trimmer is ideal for mowingin places conventional lawn mowers cannotreach. In the mowing position, keep the lineparallel to the ground. Avoid pressing thehead into the ground as this can scalp theground and damage the tool.

OPERATING INSTRUCTIONS FORUSE WITH WEED BLADES Blade Thrust is a reaction that only occurswhen using a bladed unit. This reaction cancause serious injury such as amputation.Carefully study this section. It is important thatyou understand what causes blade thrust,how you can reduce the chance of itsoccurring, and how you can remain in controlof unit if blade thrust occurs.

S WHAT CAUSES BLADE THRUST -- BladeThrust can occur when the spinning bladecontacts an object that it does not cut. Thiscontact causes the blade to stop for an instantand then suddenly move or “thrust” awayfrom the object that was hit. The “thrusting”reaction can be violent enough to cause theoperator to be propelled in any direction andlose control of the unit. The uncontrolled unitcan cause serious injury if the blade contactsthe operator or others.

S WHEN BLADE THRUST OCCURS --Blade Thrust can occur without warning ifthe blade snags, stalls, or binds. This ismore likely to occur in areas where it isdifficult to see the material being cut. Byusing the unit properly, the occurrence ofblade thrust will be reduced and theoperator will be less likely to lose control.

S Cut only grass, weeds, and woody brush upto 1 cm in diameter with the weed blade. Donot let the blade contact material it cannot cutsuch as stumps, rocks, fences,metal, etc., orclusters of hard, woody brush having adiameter greater than 1 cm.

S Keep the blade sharp. A dull blade is morelikely to snag and thrust.

S Cut only at full throttle. The blade will havemaximumcutting power and is less likely tobind or stall.

S “Feed” the blade deliberately and not toorapidly. The blade can thrust away if it is fedtoo rapidly.

S Cut only fromyour left to your right. Cuttingonright side of the shield will throw debris awayfrom the operator.

S Use the shoulder strap and keep a firm gripon the unit with both hands. A properlyadjusted shoulder strap will support theweight of the unit, freeing your arms andhands to control and guide the cuttingmotion.

S Keep feet comfortably spread apart andbraced for a possible sudden, rapid thrust ofunit. Do not overreach. Keep firm footing andbalance.

S Keep blade below waist level; it will beeasier to maintain control of unit.

S Donot raise theengine aboveyour waist asthe blade can come dangerously close toyour body.

S Do not swing unit with such force that youare in danger of losing your balance.

Bring the engine to cutting speed before enter-ing the material to be cut. If the blade does notturnwhenyousqueeze the throttle trigger,makesure shaft is fully inserted into the engine.Always release the throttle trigger and allowengine to return to idle speed when not cut-ting. The blade should not turn while the en-gine is running at idle. If the blade turns at idle,do not use your unit. Refer to theCARBURE-TOR ADJUSTMENT section or contact yourauthorized service dealer.S Maintain good firm footing while using theunit. Do this by planting feet firmly in acomfortable apart position.

S Cut while swinging the upper part of yourbody from left to right.

S As you move forward to the next area to cut,be sure to maintain your balance and footing.
