Safety Warnings Specific for Abrasive Cutting-off Operations

1. Do not “jam” the cut-off wheel or apply

excessive pressure. Do not attempt to make

an excessive depth of cut. Overstressing the

wheel increases the loading and susceptibility

to twisting or binding of the wheel in the cut and

the possibility of kickback or wheel breakage.

2. Do not position your body in line with and

behind the rotating wheel. When the wheel,

at the point of operation, is moving away from

your body, the possible kickback may propel the

spinning wheel and the power tool directly at you.

3. When wheel is binding or when interrupting a

cut for any reason, switch off the power tool

and hold the power tool motionless until the

wheel comes to a complete stop. Never attempt

to remove the cut-off wheel from the cut while

the wheel is in motion otherwise kickback

may occur. Investigate and take corrective

action to eliminate the cause of wheel binding.

4. Do not restart the cutting operation in

the workpiece. Let the wheel reach full

speed and carefully reenter the cut.

The wheel may bind, walk up or kickback if the

power tool is restarted in the workpiece.

5. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kickback.

Large workpieces tend to sag under their own weight.

Supports must be placed under the workpiece

near the line of cut and near the edge of the

workpiece on both sides of the wheel.

6. Use extra caution when making a “pocket cut”

into existing walls or other blind areas.

The protruding wheel may cut gas or water pipes,

electrical wiring or objects that can cause kickback.

Safety Warnings Specific for Sanding Operations

Do not use excessively oversized sanding disc paper. Follow manufacturer’s recommendations

when selecting sanding paper. Larger sanding paper extending beyond the sanding pad

presents a laceration hazard and may cause snagging, tearing of the disc or kickback.

Safety Warnings Specific for Wire Brushing Operations

1. Be aware that wire bristles are thrown by

the brush even during ordinary operation.

Do not overstress the wires by applying

excessive load to the brush. The wire bristles

can easily penetrate light clothing and/or skin.

2. If the use of a guard is recommended for

wire brushing, do not allow any interference

of the wire wheel or brush with the guard.

Wire wheel or brush may expand in diameter

due to work load and centrifugal forces.

Vibration Safety

This tool vibrates during use. Repeated or long-term

exposure to vibration may cause temporary or permanent

physical injury, particularly to the hands, arms and

shoulders. To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an

extended period should first be examined by a

doctor and then have regular medical check-ups

to ensure medical problems are not being caused

or worsened from use. Pregnant women or

people who have impaired blood circulation to

the hand, past hand injuries, nervous system

disorders, diabetes, or Raynaud’s Disease should

not use this tool. If you feel any medical or

physical symptoms related to vibration (such as

tingling, numbness, and white or blue fingers),

seek medical advice as soon as possible.

2. Do not smoke during use. Nicotine reduces

the blood supply to the hands and fingers,

increasing the risk of vibration-related injury.

3. Wear suitable gloves to reduce the

vibration effects on the user.

4. Use tools with the lowest vibration when there

is a choice between different processes.

5. Include vibration-free periods each day of work.

6. Grip tool as lightly as possible (while still keeping

safe control of it). Let the tool do the work.

7. To reduce vibration, maintain the tool as

explained in this manual. If any abnormal

vibration occurs, stop use immediately.

SAVE THESE INSTRUCTIONS.
