ASSEMBLY AND OPERATION

APPLICATIONS

￿Finishing of dies for press working, die casting and moulding.

￿Finishing of thread cutting dies, tools and other small parts.

￿Internal grinding of tools and machine parts.

WARNING:

To avoid the risk of serious injury, NEVER use this grinder with abrasive wheels, cut-off wheels and/ or saw blades.

4.Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs.

If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard.

5.Check the work site and surrounding area

Be sure that the work area has been thoroughly checked and prepared to avoid any unsafe conditions. Review the SAFETY section of this manual.

6.Installing a wheel

PRIOR TO OPERATION

1.Power source

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

2.Power switch

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.

3.Extension cord

When the work area is far away from the power source, use an extension cord of sufficient thick- ness and rated capacity.The extension cord should be kept as short as practicable.

WARNING:

Damaged cord must be replaced or repaired.

WARNING:

USING A WRONG SIZED WHEEL CAN CAUSE WHEEL BREAKAGE AND RESULTING SERIOUS INJURY.

In order to avoid this hazard, refer to the following illustration to determine the proper dimensions(s) of your wheel. Some guidelines:

(a)Dimension should always be less than 1/2" (13 mm). Longer lengths can result in excess vibration, wheel breakage, and the chance for serious injury.

(b)When dimension d is 1/4" (6.35 mm), the diameter of the wheel (dimension D) should be less than 1" (25 mm). NEVER use a larger diameter wheel.

(c)When dimension d is 1/8" (3.175 mm), the diameter of the wheel (dimension D) should be less than 3/8" (10 mm).

(d)Dimension L varies according to the dimension D. Dimension L can be longer as dimension D increase. Refer to the following table:
