Fig. 3

PRACTICAL GRINDER AND SANDER APPLICATIONS

1. Always hold the handle and side handle of the POWER TOOL firmly.
   Otherwise the counterforce produced may result in inaccurate and even dangerous operation.
2. Grinding pressure
   Since grinding by utilizing only the Disc Grinder's own weight is feasible, hold the Disc Grinder so that it only slightly contacts the plane to be ground.

CAUTION:

- Do not press the Disc Grinder forcibly against the plane to be ground. Heavy pressure will reduce the revolving speed and such deteriorate the finished surface, and phenomena as overload will lead to burning loss of the motor.

1. Grinding angle

Use only its peripheral surface by tilting the grinding wheel at an angle of 15^ 30^ , as shown in Fig.4-a.

CAUTION:

- Do not utilize the entire surface of grinding wheel when grinding.

1. When using a new grinding wheel in direction A (Fig.4-a), the wheel edge may cut into the workpiece. In this case, grind in direction B (Fig.4-a). Once the wheel edge is worn, the workpiece can be ground in both directions.

Fig. 4-a

The provided grinding wheel (resinoid wheel) is rated as Class A grain and #24 grain size. Therefore, it is most appropriate for heavy grinding of general steel materials.
It is also suitable for grinding other types of materials.
For a fine finish, lift the disc grinder slightly and grind slowly at the appropriate speed.
5. Precaution after use.
Do not lay the grinder down immediately after use in a place where there are many shavings and much dirt and dust until it has completely stopped revolving.

1. Do not push the sanding disc to the surface to be ground.

CAUTION:

- Do not press the Disc Grinder forcibly against the plane to be ground. Heavy pressure will reduce the revolving speed and such deteriorate the finished surface, and phenomena as overload will lead to burning loss of the motor.

1. Sanding angle

Use only its peripheral surface by tilting the sanding disc at an angle of 15^ 30^ , as shown in Fig.4-b.

Fig. 4-b

CAUTION:

- Do not utilize the entire surface of sanding disc when sanding.

MAINTENANCE AND INSPECTION

⚠ WARNING: Be sure to switch power OFF and disconnect the plug during maintenance and inspection.

1. Replacing the grinding wheel

Replace the grinding wheel when it has been worn out to about 2-3/8"(60mm) in external diameter. Confirm that there is no crack or any damage to the grinding wheel. If there is a crack or a transformation in the wheel, replace it immediately.

1. 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.

⚠ WARNING: Using this grinder with loosen screws is extremely dangerous.

1. Confirm that there is no damage in the wheel guard, the cord and the housing, etc.

Furthermore, confirm that there is no abnormality in the activation of the switch.

1. Inspecting the carbon brushes (Fig. 5)

The motor employs carbon brushes which are consumable parts. Replace the carbon brush with a new one when it becomes worn to its wear limit. Always keep carbon brushes clean and ensure that they slide freely within the brush holders.

CAUTION: Using this grinder with a carbon brush which is worn in excess of the wear limit will damage the motor.

Fig. 5
