Safety precautions 4.8.10 Guide the cut-off saw in such a way that no part of your body is within the extended swing range of the blade (18). 4.8.11 Use cutting blades only for the materials for which they are designed! 4.8.12 Do not use the cut-off saw to lift up and shovel away pieces of material and other objects.
Page 27
Safety precautions CAUTION! The rapid rotation of the cutting blade heats metal and melts it at the point of contact. Swing the guard as far down as possible behind the cut (19) in order to direct the stream of sparks forward, away from the operator (fire hazard).
Page 28
Safety precautions 4.9.8 Cut I-beams and L-bars in steps; see Figure 21. 4.9.9 Cut bands and plates like pipes: along the wide side with a long cut. 4.9.10 When cutting material under stress (supported material or material in structures), always make a notch in the thrust (pressure) side, and then cut from the tension side, so that the blade does not lock in (22).
Safety precautions 4.10 Cutting masonry concrete, asbestos or asphalt ATTENTION! Always wear approved respiratory protection! Asbestos and other materials that can release toxic substances may be cut only after notifying the proper authorities and under their supervision or that of a person appointed by them. When cutting prestressed and reinforced concrete piles, follow the instructions and standards of the responsible authorities or the builder of the structural member.

Putting into operation Putting into operation ATTENTION: Always turn off the engine and pull off the spark plug cap before doing any work on the cut-off saw! Always wear protective gloves! ATTENTIONE: Start the cut-off saw only after complete assembly and inspection.
Putting into operation Fitting cutting blades Model Inspect disc damage, SAFETY INSTRUCTIONS. Unscrew screw (9) and remove the spring washer (8). Place the cutting disc (5) on the arbour (7). NOTE: The arbor hole of the cutting disk must fit the shaft precisely. Use an adapter ring to compensate for a larger arbor hole.
Putting into operation Tightening the V-belt/Checking V-belt tension ATTENTION: Exact V-belt tension is essential for maximum cutting performance with minimum fuel consumption. Improper V-belt tension will result in premature wear to the V-belt and V-belt pulley or damage to the clutch bearing. Retighten new V-belt after first running hour! NOTE: The two fastening nuts (11) must be loosened before tightening the V-belt or checking the tension.
Putting into operation Fuels ATTENTION: The cut-off saw uses mineral-oil products (gasoline and oil). Be especially careful when handling gasoline. Do not smoke. Do not allow gasoline to come near flames, sparks or fire (explosion hazard). Gasoline 50:1 1000 cm (1 liter) 20 cm 5000 cm...
Putting into operation The 2-cycle engine oil must comply with API TC, JASO FC or ISO L- EGD specifications. NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Shake the finished mixture thoroughly before pouring it into the saw‘s tank.
Putting into operation Refuelling Fuel mixture ATTENCION: FOLLOW THE SAFETY PRECAUTIONS BY ALL MEANS! Be careful and cautious when handling fuels. The engine must be turned off and cooled down! Carefully clean the area around the fuel-tank filler neck to keep dirt from getting in the tank.
Putting into operation Starting the engine necessary 3 meters (10 feet) ATTENCION: Observe the SAFETY INSTRUCTIONS under all circumstances! Start the cut-off saw only after complete assembly and inspection! Move at least 3 m (10feet) away from the place where you fuelled the cut-off saw.

Carry out carburetor adjustment with the scope of delivery. Readjusting the idle speed Proceed as follows if the cutting blade is turning while the engine is idling: turn the throttle valve‘s stop screws (2) outwards until the cutting...
Maintenance Maintenance ATTENCION Before doing any work on the cut-off saw turn off the engine, remove the cutting blade, pull the plug cap off the spark plug and wear protective gloves! ATTENCION Start the cut-off saw only after complete assembly and inspection.
Maintenance Changing the V-belt Loosen nuts (3). Loosen the tightening screw (1) (counter-clockwise) until the end of the screw (2) is visible in the gap. Unscrew the nuts (3) and remove the cover (4). Remove the screws (5) and (7) and remove the side cover (6). NOTE: Screw (5) is longer than screws (7).
Maintenance Cleaning the protective hood NOTE: See “Fitting cutting blades“ for assembly of blades. Over time, the inside of the protective hood can become caked with material residue (especially from wet cutting), which if allowed to accumulate can hinder the free rotation of the cutting blade. For this reason the hood must be cleaned out from tim to time.
Page 51
Maintenance Loosen the screws (13) and remove the covering cap (14). Clean the sealing rings (15) with a small brush and check them for damage. Remove prefilter (17) from the filter cover. Pull air filter insert (18) from the hood. Remove the inner filter (16) from the intake opening.
Maintenance Prefilter and air cleaner insert Service-notes: Clean prefilter (1/7) daily ore more often if in the pesence of a lot of dust. Replace latest after 20 hours running time! Clean air cleaner insert (2/8) once every week, replace every 100 hours running time! This means that with proper maintenance the air cleaner insert needs be replaced after the prefilter has been replaced five times.
Maintenance Replacing the spark plug ATTENCION: Do not touch the spark plug or plug cap if the engine is running (high voltage). Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves! The spark plug must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily.
Maintenance Checking the ignition spark Insert the combination wrench (9) between the hood and cylinder only as shown. ATTENCION! Do not insert the combination tool into the spark plug hole, but make contact only with the cylinder (otherwise you may damage the engine). Using insulated pliers, hold the spark plug (10) (unscrewed but with the plug cap on) against the combination tool (away from the spark plug hole!).
Maintenance Replacing the suction head The felt filter (13) of the suction head can become clogged. It is recommended to replace the suction head once every three months in order to ensure unimpeded fuel flow to the carburetor. Unscrew the fuel tank cap (12) and pull the loss-prevention stopper out.

Maintenance Thread a new 1000 mm (40“) long and 4,0 mm (0,16“) diameter starter rope as shown in the drawing (do not forget washer (19) and then tie knots at both ends. Pull knot (20) into rope drum (21). ATTENCION: The knot or, as the case may be, the end of the rope should not jut out over the surface of the rope drum.
Maintenance NOTE: With the rope pulled all the way out, it must still be possible to turn the pulley another 1/4 turn against the return spring. ATTENCION! Injury hazard! When you pull out the starter rope hold the starter handle firmly. It will whip back if the rope drum is released by accident.
Maintenance Replacement retum springs are delivered inside a housing and pretensed. CAUTION, the spring can jump out. A spring that has jumped out can be placed back in the housing by following the drawing (pay attention to the direction of rotation!). The new return spring (4) must be lightly greased with multipurpose grease before proceeding with mounting inside the fan housing.
