GENERAL SAFETY RULES • D o not abuse the cord. Never use the cord to carry the tool or to pull the plug. Keep cord away from heat, oil, sharp edges or moving parts. Contact Customer Service if cord is damaged and do not use the saw. Damaged cords increase the risk of electric shock. • Do not use tool if switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is dangerous and must be repaired. • Depending upon use, the switch may not last the life of the saw.
GENERAL SAFETY RULES PERSONAL SAFETY • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. • Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
GENERAL SAFETY RULES • Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the tool’s operation. If damaged, contact Customer Service before using. Many accidents are caused by poorly maintained tools. Develop a periodic maintenance schedule for your tool. Contact Customer Service to have defective switches replaced. Keep handles dry, clean, and free from oil and grease. • Use only accessories that are recommended by the manufacturer for your model.
SPECIFIC SAFETY RULES If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris. Disconnect the plug from power source. Periodically remove the blade, clean the upper and lower guards and the hub area with a degreaser and wipe it dry, or blow it clean with compressed air.
SPECIFIC SAFETY RULES Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: • Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. • Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight.

OPERATION DUALSAW BLADES • Keep the blades clean, sharp and properly set. Using a dull blade will place a heavy load on your saw and increases the danger of kickback. Keep extra blades on hand, so sharp blades are always available. • Gum and wood pitch hardened on your blade will slow your saw down. Use gum and pitch remover, hot water or degreaser to remove these accumulations. DO NOT use gasoline. CAUTION! Don’t use the saw when the blade guard is not operating properly.
OPERATION CAUTION! Maintain control of the saw to make sawing safer and easier. Loss of control of the saw could cause an accident resulting in possible serious injury. STARTING A CUT • Slide the switch to ON to start the saw. Always let the blades reach full speed before you begin to cut into the work piece. • Apply steady and even pressure when making a cut. Forcing the saw causes rough cuts and could shorten the life of the saw or cause kickback.
OPERATION CUTTING DIFFERENT MATERIALS Fig. 14 Fig. 15 FLAT STRIP SOFT METALS Move blades in a 90 degree angle across the piece. (Fig. 14) Apply lubrication sticks through the lubrication system and then cut. (Fig. 15) Fig. 16 Fig. 17 SQUARE TUBE U-SHAPE MATERIAL Move blades to the tube in a diagonal direction. (Fig. 16 Move blades to the U-profile material from the diagonal direction. (Fig. 17) Fig. 18 Fig.

MAINTENANCE • When the blade is not in use, it should be stored in its original sheath, well cleaned and coated with an antirust agent. LUBRICATION • All of the bearings in this tool are lubricated with a sufficient amount of highgrade lubricant for the life of the tool under normal operating conditions. Therefore, no further lubrication is required. DOUBLE INSULATION • Double insulation is a concept in safety in electric power tools, which eliminates the need for the standard 3-wire ground power cord.
