STANDARD ACCESSORIES

(1) Cut-off wheel: 1
(2) Hex. bar wrench: 1

APPLICATION

Cutting of various metallic materials such as pipes, round bars, shaped steel and siding board.

PRIOR TO OPERATION

1. Power source
   Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2. Power switch
   Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. Extension cord
   When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Install the machine on a level flat place, and keep it in a stable condition. Prior to shipping, the equipment is subjected to a rigid factory inspection to prevent electric shocks during operation.

5. Since movable portions are secured by tension of a chain while in transit, remove the chain from the chain hook by slightly depressing the switch handle.

6. Ascertain that all cut-off wheels are in perfect condition, and do not display scars and cracks.

7. Although they have been fully clamped at the factory prior to delivery, reclamp the clamping nuts securely for safety.

8. Possible accidents such as a cracked cut-off wheel is prevented by this protective cover (wheel cover).
   Although it has been fully clamped at the factory prior to delivery, securely reclamp the mounting screws for safety.

9. When replacing the cut-off wheel, ensure that the replacement cutting wheel has a designed circumferential speed in excess of 4800 m/min.

10. Ensure that the bar spanner used for tightening or removing the cut-off wheel is not attached to the machine.

11. Check that the work piece is properly supported. Ensure that the material is securely fastened with the vise. If it is not, a serious accident could be caused if the material comes loose or the cut-off wheel breaks during operation.

12. Ensure that the abrasive wheel is correctly fitted and tightened before use and run the machine at no-load for 30 seconds in safe position, stop immediately if there is a considerable vibration or if other defects are detected. If this condition occurs, check the machine to determine the cause.

13. Rotate the cut-off wheel to inspect any facial deflection. A heavy deflection will cause the cutoff wheel to shift.

14. Ensure that ventilation openings are kept clear when working in dusty conditions. If it should become necessary to clear dust, first disconnect the machine from the mains supply.

CUTTING PROCEDURES

CAUTION
It is dangerous to remove or install the workpiece while the cut-off wheel turning.

1. Operating the switch
   The switch is switched on by manually pulling the trigger and cut off by releasing the trigger to the original location. The switch will not operate unless the stopper has been pushed in.

2. Cutting

3. Rotate the cut-off wheel, gently press down the handle, and bring the cut-off wheel close to the cutting material.

4. When the cut-off wheel contacts the cutting material, gently press down the handle further and start cutting.

5. When cutting (or designated slotting) is completed, raise the handle and restore it to its original position.

6. At the termination of each cutting process, turn OFF the switch to stop rotation and proceed with the subsequent cutting job.

CAUTION

It does not necessarily cut rapidly when putting more force on the handle.
Too much force on the handle will put excessive pressure on the motor and reduce its capacity. Do not fail to switch OFF the switch after operation is completed and pull the plug out.

MOUNTING AND DISMOUNTING THE CUTOFF WHEEL

1. Dismounting the cut-off wheel (Fig. 2)

2. Press the stopper and loosen the bolt with a hex. bar wrench.
   CAUTION
   When the mounting shaft for cut-off wheel cannot be fixed with pressing the stopper, turn the bolt with a hex. bar wrench while pressing the stopper. The mounting shaft for cut-off wheel is fixed when the stopper has been lowered.

3. Remove the bolt, washer (A), and the wheel washer and detach the cut-off wheel.

4. Mounting the cut-off wheel
   Throughly remove dust from the wheel washers and bolt then mount the wheel by following the dismounting procedures in reverse order. Be sure to attach the sub-cover at the end.
   CAUTION
   Confirm that the stopper which was used for installation and removal of the cut-off wheel has returned to the retract position.

HOW TO OPERATE

1. Procedure for fixing the cutting material (Fig. 8 and 9)
   Place the workpiece material between vise (A) and vise (B), raise the clutch and push the screw handle to bring vise (A) lightly into contact with the workpiece material, as shown in Fig. 8.
   Then, turn the clutch down, and securely fix the workpiece material in position by turning the screw handle. When the cutting job is completed, turn the screw handle 2 or 3 times to loosen the vise, and remove the workpiece material, as shown in Fig. 9.
   CAUTION
   The wheel continues to rotate after the machine is switched off.
   Never remove or install a workpiece material while the cut-off wheel is rotating, to avoid personal injury. Long workpieces must be supported by blocks nonflammable material on either side so that it be level with the base top.

2. Cutting at angles (Fig. 3 and 4 )
   (1) The machine permits cutting at angles of 45° or 60°.
   (2) Loosen the two M10 hexagon socket head bolts on the vice (B), then set the working surface on the vice-jaw at any angles of 0°, 30°, or 45° as shown in Fig. 4. Upon completion of setting, securely tighten the two 10 mm bolts.
   (3) When wide material is cut with angle, it will be firmly camped by fixing a steel board like Fig. 5 to the vise (B).

3. Moving the stationary vise-jaw (Fig. 6)
   The vise opening is set at the maximum of 170 mm when shipped from the factory. In case an opening of more than 170 mm is required, move the vise to the position shown by the chain line after unscrewing the two bolts. The maximum opening can be set in two steps 205 mm and 240 mm. When the cutting material is excessively wide, the vise can be effectively used by repositioning the stationary side of the vise-jaws.

4. How to use metallic block (Fig. 7)
   When the cut-off wheel has a reduced outer diameter, insert between the vise (A) and (B) a metallic block slightly smaller than the dimension of workpiece being cut to use the cut-off wheel economically.

MAINTENANCE AND INSPECTION

CAUTION
Be sure to switch off and pull off the plug from the power outlet before inspection and maintenance.

1. Replacing a cut-off wheel
   When the cut-off wheel has already become dull while continually using, the unnecessary load is got from the motor. Consequently, redress or replace a dull cut-off wheel to ensure grinding efficiency.

2. Inspecting the carbon brushes (Fig. 10)
   The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Number shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

3. Inspecting the mounting screws
   Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

4. Lubrication
   Supply oil in the following oil supply points once a month so as to keep the machine workable for a long time (See Fig. 1 ).
   Oil supply points

   • Rotary part of shaft
   • Rotary part of vise
   • Slide way of vise (A)

5. Cleaning
   Wipe off chip and waste adhered to the machine with a cloth or the like time to time. Be careful not to make the motor portion wet with oil or water.
