SPECIAL NOTICE:

Exposure to vibra- tions through prolonged use of gasoline pow- ered hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal swellings. Prolonged use in cold weather has beenlinked to blood vesseldam- age in otherwise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of this tool and seekmed- ical attention. An anti-vibration system does not guarantee the avoidance of these prob- lems. Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condi- tion of this tool.

ASSEMBLY

WARNING: Make sure unit is proper-ly assembled and all fasteners are secure. Examine parts for damage. Do not use dam- aged parts. It is normal for the fuel filter to rattle in the empty fuel tank.
Finding fuel or oil residue onmuffler is normal due to carburetor adjustments and testing done by the manufacturer. SHAFT ASSEMBLY
CAUTION: When assembling shaft, place the unit on a flat surface for stability.

1. Align grooves on upper and lower shafts.

2. Push the two shafts together until the lowershaft is fully seated in the upper shaft (the shafts lock into place).

3. Slide lower locking sleeve assembly over upper locking sleeve assembly and tight-en by turning clockwise.
   
   NOTE: If locking sleeve assembly will nottighten, the shafts are not fully seated. ADJUSTING THE HANDLE

WARNING: When adjusting the assist handle, be sure it remains above the locking sleeve assembly and below the mark or arrow on the shaft.

1. Loosen wing nut on handle.
2. Rotate the handle on the shaft to an up- right position; retighten wing nut.

ATTACHING THE SHIELD

WARNING: The shieldmust be prop- erly installed. The shield provides partial protection from the risk of thrown objects to
the operator and others and is equipped with a line limiter which cuts excess line. The line limiter (on underside of shield) is sharp and can cut you.

1. Remove nut from shield.
2. Insert bracket into slot on shield.
3. Pivot shield until bolt passes through hole in bracket.
4. Reinstall nut and tighten securely with wrench (provided).

OPERATION

WARNING: Be sure to read the fuel information in the safety rules before you be- gin. If you do not understand the safety rules, do not attempt to fuel your unit. Contact an authorized service dealer.
FUELING ENGINE

WARNING: Remove fuel cap slowly when refueling.
This engine is certified to operate on un- leaded petrol. Before operation, petrol must be mixed with a good quality 2–cycle air– cooled engine oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained bymixing 5 liters of unleaded petrolwith 0,125liter of oil.
DO NOT USE automotive oil or marine oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on oil container. Once oil is added to petrol, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit.

CAUTION: Never use straight petrol in your unit. This will cause permanent engine dam- age.

FUEL REQUIREMENTS

Use good quality unleaded petrol. The lowest recommended octane grade is 90 (RON).

IMPORTANT

Use of alcohol blended fuels (morethan 10%al- cohol) can cause major engine performance and durability problems.

WARNING: Incorrect use of fuel and/ or lubricants will cause problems such as: improper clutch engagements, overheat- ing, vapor lock, power loss, lubrication defi- ciency, deterioration of fuel lines, gaskets
and internal carburetor components, etc. Alcohol blended fuels will cause a high ab- sorption of moisture in the fuel/oil mixture, causing the separation of oil and fuel.

HOW TO STOP YOUR UNIT

S To stop the engine, move the ON/OFF switch to the OFF position.

HOW TO START YOUR UNIT

WARNING: The trimmer head wil turn while starting the engine. Avoid any con- tact with the muffler. A hot muffler can cause serious burns.

STARTING A COLD ENGINE (or a warm engine after running out of fuel)

1.  Set unit on a flat surface.

2. Move ON/OFF switch to the ON position.

3. Slowly press the primer bulb 6 times.

4. Move choke lever to FULL CHOKE posi- tion.

5. Squeeze and hold trigger through all re- maining steps.

6. Pull starter rope handle sharply until en- gine sounds as if it is trying to start, but do not pull rope more than 6 times.

7. As soon as engine sounds as if it is trying to start, move choke lever to HALF CHOKE.

8. Pull starter rope sharply until engine runs, but no more than 6 pulls. If the engine doesn t start after 6 pulls (at the HALF CHOKE position), move the choke lever to. the FULL CHOKE position and press the
   primer bulb 6 times. Squeeze and hold the throttle trigger and pull the starter rope 2 more times. Move the choke lever to the HALF CHOKE position and pull the starter rope until the engine runs, but nomore than 6 pulls. NOTE: If engine still doesn t start, it is probably flooded. Proceed to START- ING A FLOODED ENGINE.

9. Once the engine starts, allow it to run 10 seconds, then move the choke lever to RUN. Allow the unit to run for 60 more seconds at RUN before releasing the throttletrigger. NOTE: If engine dieswith
   the chokelever in the RUN position,move the choke lever to the HALF CHOKE position and pull the rope until engine runs, but no more than 6 pulls.

STARTING A WARM ENGINE

1. Move ON/OFF switch to the ON position.
2. Move the choke lever to the HALF CHOKE position.
3. Squeeze and hold the throttle trigger. Keep throttle trigger fully squeezed until the engine runs smoothly.
4. Pull starter rope sharply until engine runs, but no more than 5 pulls.
5. Allow engine to run 15 seconds, thenmove the choke lever to the RUN position.

NOTE: If engine has not started, pull starter rope 5more pulls. If engine still does not run, it is probably flooded.

STARTING A FLOODED ENGINE

Flooded engines can be started by placing the choke lever in theRUN position; then, pull the rope to clear the engine of excess fuel.
This could require pulling the starter handle many times depending on how badly the unit is flooded. If the unit still doesn t start, refer to TROUBLESHOOTING TABLE.

OPERATING INSTRUCTIONS OPERATING POSITION

WARNING: Always wear eye protec- tion and hearing protection. Never lean over the trimmer head. Rocks or debris can rico- chet or be thrown into eyes and face and cause blindness or other serious injury.
Do not run the engine at a higher speed than necessary. The cutting line will cut efficiently when the engine is run at less than full throttle. At lower speeds, there is less engine noise and vibration. The cutting line will last longer andwill be less likely to “weld# onto the spool. Always release the throttle trigger and allow the engine to return to idle speed when not cutting.
To stop engine: S Release the throttle trigger.S Move the ON/OFF switch to the OFF posi-tion.

TRIMMER LINE ADVANCE

Advance line by tapping the bottomof the cut-ting head lightly on the groundwhile 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 mm diameter line.Other sizes and shapes of linewill not ad- vance properly andwill result in improper cut- ting 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: Useminimumspeed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), whichcan damage thetrimmer 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 mini- mumline wear by not crowding the line into the cutting area. The right and wrong ways are shown below.
• The line will easily remove grass and weeds fromaroundwalls, 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.
• Formowing or sweeping, use full throttlefor 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 tomake con-
  tact. Do not force trimmer line into work area.
  
  SCALPING — The scalping technique removes unwanted vegetation. Hold the bottom of the trimmer head about 8 cmabove 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.

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 rotat- ing line can be used for a quick and easy clean up. Keep the line parallel to and above the surfaces being swept and move the tool from side to side.

MAINTENANCE

WARNING: Disconnect the spark plug before performing maintenance except for carburetor adjustments.
CHECK FOR LOOSE FASTENERS AND PARTS

• Spark Plug Boot
• Air Filter
