Resumen del manual
Always hold the tool ONLY by the insulated gripping surfaces to prevent any electric shock if you accidentally cut through a "live" wire. Water pipes in "blind" areas must be drained and capped before cutting. 8. Be careful not to hit the end of the blade against something during operation. Damage to the tool or dangerous blade breakage may occur. 9. Watch out for cut-off portions of the workpiece being cut. They may fall and injure you or someone near you. IO.When cutting metals, be cautious of hot flying chips. 1 1. Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin. 12. If you withdraw the blade from the workpiece during operation, strong reaction will be produced, causing the blade to snap or causing you to lose your grip and control of the tool. Always switch off the tool and wait until the blade has come to a complete stop before withdrawing the blade from the workpiece. SAVE THESE INSTRUCTIONS. Installing or removing saw blade CAUTION : Always be sure that the tool is switched off and unplugged before installing or removing the blade. The blade installing position varies depending upon the type of blade being used. Install the blade in the proper position as shown in the figures below. Installing position for blades No. 25 and 26. Installing position for blades No. 21, 22, 23 and 24. To install the blade, loosen the bolt with the hex wrench. Insert the blade between the blade clamp and the slider so that the pin on the slider fits in the hole in the blade shank. Tighten the bolt securely while making sure that the blade will not be extracted even though you try to pull it out. CAUTION : If you tighten the bolt without the pin on the slider fitting properly in the hole in the blade shank, the pin or the blade shank will be damaged. This may cause the blade to be extracted unexpectedly during opera- tion. - Blade clamp ~ To remove the blade, follow the installation procedures in reverse. Installing or removing vise assembly To install the vise assembly, insert the shaft of the vise assembly into the hole in the housing as far as it will go. The shaft of the vise assembly will be grasped by the stop- per automatically. Make sure that the vise assembly cannot be removed even though you try to pull it out. To remove the vise assembly, raise the stopper and then pull the vise assembly out while turning the vise assembly. CAUTION : Do not use the vise assembly when cutting pipes up to 25 mm (1") in diameter or thin wall pipes. Securing tool to workpiece Turn the vise handle counterclockwise until approx. 25 mm (1") threaded portion is visible. Place the vise assembly on the part of the workpiece which will not fall off after the cut is made. Wrap the chain around the workpiece and hook the chain onto the chain hook on the vise assembly while maintaining tension on the chain. Turn the vise handle clockwise to tighten the chain. Switch action Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. A speed control screw is provided so that maximum tool speed can be limited (variable). Turn the speed control screw clockwise for higher speed, and counter- clockwise for lower speed. CAUTION : Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Overload protector The overload protector automatically cuts out to break the circuit whenever heavy work is prolonged. If this occurs, release the trigger switch and withdraw the blade from the workpiece. Press the restart button to resume operation. Operation 1. Cutting with the vise assembly : Secure the tool to the workpiece as de- scribed in “Securing tool to workpiece” section. Bring the blade into light con- tact with the workpiece. First, make a pilot groove, using a slower speed until the blade has cut to a depth of 1-3 mm (3/64”-1/8’)).Then use a faster speed to continue cutting. CAUTION : Do not lift the tool handle too hard during operation. This may cause a bevel cut, damage to the blade or damage to the tool. When cutting the workpiece which is not secured with anything other than the vise assembly, grasp the vise handle with your left hand and the tool handle with your right hand. Then cut the workpiece by raising the tool handle while pulling the vise handle toward you. Be extremely careful in these situa- tions to avoid losing control of the tool and workpiece. CAUTION : When cutting the workpiece near an obstacle like floor or wall, use wood blocks to prevent the blade from hitting against the obstacle. 2 Cutting without the vise assembly : Press the shoe firmlv against the work- MAINTENANCE CAUTION : Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
