ALWAYS hold the tool firmly with one hand on rear handle and the other on the side handle. Turn the tool on and then apply the wheel or disc to the workpiece.

In general, keep the edge of the wheel or disc at an angle of about 15 degrees to the workpiece surface.

During the break-in period with a new wheel, do not work the grinder in the B direction or it will cut into the workpiece. Once the edge of the wheel has been rounded off by use, the wheel may be worked in both A and B direction.

Mount the rubber pad onto the spindle. Fit the disc on the rubber pad and screw the lock nut onto the spindle. To tighten the lock nut, press the shaft lock firmly so that the spindle cannot revolve, then use the lock nut wrench and securely tighten clockwise.

To remove the disc, follow the installation procedure in reverse.

OPERATION

WARNING:

•It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.

•ALWAYS replace wheel if tool is dropped while grinding.

•NEVER bang or hit grinding disc or wheel onto work.

•Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kickback.

•NEVER use tool with wood cutting blades and other sawblades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury.

CAUTION:

•Never switch on the tool when it is in contact with the workpiece, it may cause an injury to operator.

•Always wear safety goggles or a face shield during operation.

•After operation, always switch off the tool and wait until the wheel has come to a complete stop before putting the tool down.

Unplug tool and place it upside down allowing easy access to spindle. Remove any accessories on spindle. Mount urethane washer then thread wire cup brush onto spindle and tighten with supplied wrench. When using brush, avoid applying too much pressure which causes over bending of wires, leading to premature breakage.

NOTE:

•When using wire cup brush, mount urethane washer to the spindle. It will make it easier to remove wire cup brush.

Operation with wire wheel brush (optional accessory)

CAUTION:

•Check operation of wire wheel brush by running tool with no load, insuring that no one is in front of or in line with the wire wheel brush.

•Do not use wire wheel brush that is damaged, or which is out of balance. Use of damaged wire wheel brush could increase potential for injury from contact with broken wires.
