SAFETY PRECAUTIONS General precautions The operator MUST read this instruction manual to ensure safe operation (even if you already have experience in using cutoff saws). It is important to be familiar with the operation of this particular cutoff saw. Users insufficiently informed will endanger themselves as well as others due to improper handling.
The helmet visor (B) protects the face from dust and material grains. In order to prevent injuries to eyes and face, always wear protective goggles (C) or visor when using the Power Cut. To prevent hearing damage, always wear suitable personal hearing protection.

Before starting the engine, move to a location at least 3 meters (approx. 3 1/4 yards) from where you fuelled the Power Cut (7), but not within the extended swing range of the cutting disc (direction of sparks). Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near 3 meters future.
Putting into operation Do not work on your own. There must be someone around in case of an emergency (within shouting distance). Observe all anti-noise regulations when working in residential areas. Never use the Power Cut near inflammable materials or explosive gases! The Power Cut can create sparks leading to fire or explosion! Make sure that all persons within 30 meters (33 yards), such as other workers, are wearing protective...

Caution! Never change direction (turning radius less than 5 meters / 5 1/2 yards), exert lateral (sideways) pressure, or tip the Power Cut during cutting (11)! Use a cutting disc only for cutting the materials it is intended for. The proper type of disc must be used, for either metals or concrete.
Maintenance Switch off the engine before inspecting the V-belt Refuelling tension or tightening it, replacing the cutting Changing cutoff wheel, repositioning the cutter attachment (side or discs middle position) or eliminating faults (14). Repositioning the Turn off the engine immediately and check the disc if cutting attachment you hear or feel any change in cutting behaviour.
Working behavior / Method of working Before starting work, check the work area for any hazards (electrical wires, inflammable substances). Clearly mark the work area (for example with warning signs or by cordoning off the area). When working with the Power Cut hold it firmly by the front and rear handles.
Page 16
CAUTION! The rapid rotation of the cutting disc 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). Determine the direction of cutting, mark the cut and apply the disc to the material at moderate speed, to cut a guide groove before going to top speed and applying...

IMPORTANT! 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.
When cutting slabs to size, you need not cut through the entire material thickness (creating unnecessary dust). Instead, simply make a shallow groove, and then knock off the excess material cleanly on a flat surface (25). CAREFUL! When cutting into lengths, cutting through material, making cutouts, etc., always make sure to plan the direction and sequence of cuts in such a way that the disc does not get jammed by the cut-off piece, and that...
adjusted correctly. Clean the Power Cut regularly. Check the fuel tank cap regularly for good sealing. Ovserve the accident prevention instructions issued by trade associations and insurance companies. NEVER make any modifications to the Power Cut! You will only be putting your own safety at risk! Perform only the maintenance and repair works described in the instruction manual.
PUTTING INTO OPERATION CAUTION: Always turn off the engine and pull off the spark plug cap before doing any work on the Power Cut! Always wear protective gloves! CAUTION: Start the Power Cut only after complete assembly and inspection. For the the following work, use the assembly tools included with delivery: 1.
Tightening the V-belt / Checking V-belt tension IMPORTANT: 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 wheel 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.
Fuels CAUTION: Power 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 Fuel mixture The Power Cut is powered by a high-performance two-stroke engine.
Refuelling IMPORTANT: FOLLOW 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. Place the unit on its side on an aven surface.
Turn the hood lock (2) to position and hold it there. Pivot the hood (3) back as far as it will go. Release the hood lock and pivot the hood lightly back and forth until the lock engages. Cold-starting Move the combination switch (5) up (choke position). Grasp handle (hand pressure actuates the grip throttle lever lock (7)).
Stopping the engine Push the combination switch (1) down to position Working in winter In conditions of low temperatures and high humidity the carburetor can ice up. To prevent this, at temperatures below 0 C / 32 F hot air from the cylinder chamber can be inducted.
Adjusting the carburetor Set the idling speed with a screwdriver (width NOTE: The Power cut has been equipped of blade: 4 mm). with an electronic ignition to limit the The screwdriver shown has a molded-on lug to speed. The carburetor also has a fixed jet assist in adjustment.
MAINTENANCE CAUTION: Before doing any work on the Power Cut turn off the engine, remove the cutting disc, pull the plug cap off the spark plug and wear protective gloves! CAUTION: Start the Power Cut only after complete assembly and inspection. IMPORTANT: Because many of the parts and assemblies not mentioned in this Instruction Manual are vital to...
Cleaning the protection hood 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 disc. For this reason the hood must be cleaned out from tim to time. Take off the cutting wheel with spring washer and remove the accumulated material from inside the hood with a strip of wood or similar implement.
Foam prefilter and inner filter IMPORTANT: Do not use fuel to clean the foam prefilter and inner filter! If the foam prefilter (1) and inner filter (2) are dirty, wash them with dishwashing liquid in lukewarm water. Dry thoroughly! NOTE: Under very dusty conditions it will be necessary to clean the foam prefilter daily.
Checking the ignition spark Insert the combination wrench (9) between the hood and cylinder only as shown. CAUTION! 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!).
Guide the cable into the recess (22) on the cable drum and use the cable to turn the drum two turns in the direction shown by the arrow. Holding the cable drum in your left hand, straighten out the twist in the cable with your right hand, pull the cable tight, and hold.
Cutting attachment in central / side position NOTE: The Power Cut is delivered with the cutting attachment mounted in the middle position (1). For cutting up against obstacles, such as curbs or walls, the cutting attachment can be mounted to one side (2). Use this position only when actually necessary, and afterwards return the cutting attachment to the middle position.
