SAFETY RULES Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
ADDITIONAL SAFETY RULES FOR ABRASIVE CUT-OFF SAWS 1. WARNING: Do not operate your abrasive cut-off saw until it is completely assembled and installed according to the instructions. starting cut. 20. AFTER TURNING MACHINE ON, lower wheel lightly until it comes into contact with the workpiece and then draw wheel firmly through the cut. DO NOT allow the wheel to chatter and jump as this may cause the wheel to wear out of round, resulting in poor cutting and possible broken wheels. 2.
UNPACKING Your new 14 Abrasive Cut-Off Saw is shipped complete in one carton. Carefully unpack the saw from the shipping container. Fig. 2 illustrates the saw after it has been removed from the container. Fig. 2 MOVING CUTTINGHEAD TO THE UP POSITION 1. For shipping purposes the cuttinghead (A) Fig. 3, has been clamped in the down position by means of the holddown chain (B). To move the cuttinghead (A) to the up position, simply unhook the chain (B) from the handle housing. 2. Fig.
CONNECTING SAW TO POWER SOURCE POWER CONNECTIONS A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be protected with a 20 Amp fuse. Have a certified electrician replace or repair a worn cord immediately. Before connecting the motor to a power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as stamped on the motor nameplate. Running on low voltage will damage the motor.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and a 3-hole receptacle which will accept the tool’s plug When using an extension cord, be sure to use one heavy enough to carry the current of the saw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Fig. 6A shows the correct gage to use de-pending on cord length.
VISE Clamping the workpiece can be accomplished quickly and easily as follows: E 1. Lift half-nut (A) Fig.10, off screw (B). B 2. Pull out screw handle (C) Fig.10, far enough to allow workpiece (D) to be placed in vise opening against rear vise clamp (E) as shown. NOTE: It is not necessary to thread screw handle (C) when the half-nut (A) is in the raised position. The screw handle (C) can be rapidly pulled out or pushed in. A C D Fig. 10 3. Push in on screw handle (C) Fig.
ADJUSTING DOWNWARD TRAVEL OF ABRASIVE WHEEL A stop screw (A) Fig. 14, is provided to limit the downward travel of the abrasive wheel. This adjustment is made by loosening lock nut (B) and turning stop screw (A) in or out as desired. Then tighten lock nut (B). A B Fig. 14 Fig. 15 illustrates edge of the arm casting (C) contacting stop screw (A), limiting the downward travel of the abrasive wheel.
CARRYING HANDLE B When transporting the machine, the cuttinghead should always be locked in the down position by means of the holddown chain (A) Fig. 18. A carrying handle (B) is provided for ease of transportation. A Fig. 18 OPERATION After clamping the workpiece securely in the vise, turn the machine on and allow the motor to come up to full speed. Lower the wheel (A) lightly until it comes into contact with the workpiece (B), as shown in Fig. 19.
Fig. 22 illustrates the cut-off piece after the cut is completed. NOTE: The number of cuts per wheel, as well as the quality of cut, may vary considerably with the cutting time. Fast cuts cause the wheel to wear more rapidly, but also help to reduce discoloration and burr. Fig. 22 MAINTENANCE CHANGING THE WHEEL 1. DISCONNECT THE MACHINE FROM THE POWER SOURCE. 2. Rotate the front wheel guard (A) Fig. 23, to the up position, as shown. A Fig. 23 3. Press in on arbor lock (B) Fig.
BRUSH INSPECTION AND REPLACEMENT CAUTION: BEFORE INSPECTING BRUSHES, DISCONNECT THE MACHINE FROM THE POWER SOURCE. A Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after a new set of brushes has been installed. Fig. 26 After the first check, examine them after about 10 hours of use until such time that replacement is necessary. The brush holders (A) Fig. 26, are located on the motor housing opposite each other. Fig.
