This will ensure exhaust fumes are directed away from the operator and will not be obstructed by the operators clothing. If you have not used a trimmer before, spend some time in becoming famillar with the controls and method of usage before operation. Check the machine carefully before using it. Make sure that there are no loosened screws, damaged parts or fuel leakages. Replace damaged or excessively worn accessories (blades, string heads, quards) Ensure all maintenance or repair work is carried out by an authorised service center. NB. In order to maintain performance and safety, be sure to use original spare parts and accessories. Avoid using the trimmer over excessively long periods of time. Excessive amounts of vibration can be harmful.

1) Remove from the working area grit, debris,

ropes, metal parts or any other object which might get entangled around the rotating parts or be dangerously projected. Use only the correct accessory recommended! for the type of vegetation to be cut. Do not let the rotating blade contact any foreign object such as stones, rocks, cans etc. Secure hair to keep it above shoulder height. Before starting to work fit the hamness. Adjust harness with the buckle so that the trimmer is well balanced on your right side and the blade or string head is parallel to the ground. Alays maintain à firm foothold and à good balance while using the machine. Do not move backwards while you work as obstacles may not be visible. The fiting of the safety pole barrier is obligatory on units equipped with à delta shaped handle when used with a metal blade The purpose of this safety pole barrier is to maintain a safe distance between the metal blade and the user under all normal or exceptional circumstances.

2) Hamess ring (B) must never be moved from its

original position to avoid unbalancing the unit. Front handies can be separately adjusted to make usage easier on units fitted with “U” shaped handies.

3) The following accessories can be assembled to

your timmer: a) blade, b) nylon string head Do not attach any blade to a unit without proper installation of all required parts. Failure to se the proper parts can cause the blade to fiy off and seriously injure the operator and/or bystanders.

&) WHEN USING A BLADE ENSURE THE

CORRECT GUARD IS FITTED. b) WHEN USING À NYLON STRING HEAD ENSURE THE CORRECT GUARD IS FITTED. When using the unit always hold the front part of the machine (blade or nylon string head) below your waist. NYLON STRING HEAD: Always make sure it has been correctiy assembled and fittedl The nylon head is suitable to cut grass and weeds wherever there might be obstacles like trees, fences or walls. The nylon string head also reduces the likelihood of damaging small plants and trees bark. Only use flexible, nonflament nylon line in the nylon line head as specified by the manufacturer. Never use metalic line which could break off and become a dangerous projectil. BLADE: Always make sure it has been correctly fitted. When fiting or changing a cutting device, ensure you follow the instructions in the section “Blade or nylon sting head assembly" with extreme precision. Fit these cutting devices using all and only the parts as described, and in the correct order.

4) BLADES: you can cut any type of grass,

brushwood or shrub. Operate the machine Ike a sickle always cutting at full throttle.

5) WARNING: always use a well sharpened blade.

A blade with wo teeth besides providing poor performance might also generate a sudden thrust, This can result in a violent sideways kick caused when the blade touches against wood or solid bodies, such thrust might then cause the operator to loose control of the machine itself. Never attempt to work with a damaged blade but replace it with a new one. THRUST: can occur when using any type of circular blade within the risk area: therefore it is advisable to cut using the remaining area of the blade. CIRCULAR SAW BLADE: it can be used to cut sappling, small trees with a diameter up to 7 cm. to clean shrubs.

WARNING: IF A METAL 24-80 TOOTH BLADE

AND SPARE PARTS INCREASES THE RISK OF ACCIDENTS AND IN SUCH A CASE THE COMPANY IS NOT LIABLE FOR DAMAGE TO PEOPLE AND/OR THINGS. D. FUEL 1 Use only fuel recommended by this manual. This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oil mix Use unleaded petrol with a minimum octane rating of 90. Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol The use of sub-standard petrol or oil may reduce performance or reduce the life of certain components. UNLEADED PETROL If using unleaded petrol, you must use a totally synthetic 2-stroke engine oil or branded 2-stroke engine oil, see table. IMPORTANT Always shake the fuel mix container thoroughiy before pouring any fuel mix. Fuel mix properties may deteriorate with time and should be used up within 2 months. We recommend that you prepare fuel mix according 10 your immediate requirements only. Never use fuel mix more than 2 months old so as to avoid possible engine damage. WARNING Do not smoke when re-fuelling Always open the fuel cap slowly, to release any pressure build up in the tank Re-fuel in open spaces only, keeping away from naked flames or Sparks.

SAFE STORAGE OF FUEL

Petrol fuel mix is highly inflammable. Put out all cigarettes, pipes and cigars before working with fuel. Avoid spiling fuel. Store fuel in a cool, well ventilated place, in an approved container specifically designed for the purpose. Never store engine with fuel in the tank in enclosed, poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light such as in a furnace, water heater, clothes dryer etc. Petrol fumes can cause an explosion or a fire. Never store large amounts of fuel. To prevent possible restarting problems avoid running the fuel tank dry, This also helps to extend engine life. E. SAFETY GUARD ASSEMBLY:

1) In the interest of safety, it is imperative that the

unit is used with the correct guard (P/N 247208) when using any blade or a nylon string head, except the 24-80 tooth blade. Line cutter blade (D: assemble as illustrated.

2) When using a saw tooth blade (optional

accessory), the correct guard must be fitted (P/N 240559). A double shoulder harness must also be worn. Only use blades or nylon string heads clearly marked with a maximum speed of at least 10,500 min*. Follow the fitting instructions carefully. N.B: Saw tooth blades (24 - 80 tooth) have a central base diametre of 20mm and therefore require the use of the appropriate size top flange to ensure a correct fit. The part number is detailed in the cutting attachment summary chart.

The carburetor is adjusted for normal operation during production. The carburetor has three adjustment possibilties: L: The needie screw (L) governs the fuel flow at low speed and also the acceleration from low to full speed. To set low speed screw (L): close screw (L) tuming it clockwise without forcing CY Then open screw 1 full turn (counterclockwise If acceleration is not smooth, open another 1/8 turn to increase fuel flow . H: The needle screw (H) governs fuel flow at high speed (throttle valve fuly open) To set high speed screw (H) : close screw (H) tuning it clockwise without forcing CY . Then open screw 1 full turn (counterclockwise D). If the engine speed is too high open the screwr about 1/8 turn (counterclockwise I: The (1 IDLE) screw controls the throttie opening to govem idie speed (2.800 min) adjust as necessary. CAUTION: increased idle speed may cause blade or nylon string head movement. For precise adjusting contact an authorised service station which offers the latest in toll, parts and technical assistance. REGULAR MAINTENANCE, From time to time ensure all screws are tight. Replace damaged, worn, cracked or warped blades. Always make sure nylon string head or blade have been assembled correctiy (see sections NYLON STRING HEAD and BLADE ASSEMBLY) and blade fastener is tightened.

1) AIR FILTER CLEANING

(at least every 25 working hours). A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum speed and cause high fuel consumption and/or difficult starting Remove filter cover as shown in figure 1. Carefuly clean the inside of filter box. The filter can also be cleaned with compressed air.

2) Every 50 working hours inject the gearcase
