10. 

Keep bystanders a safe distance away from 

work area. Anyone entering the work area 

must wear personal protective equipment.

 

Fragments of workpiece or of a broken wheel may 

fly away and cause injury beyond immediate area 

of operation.

11. 

Hold the power tool by insulated gripping 

surfaces only, when performing an operation 

where the cutting accessory may contact hid-

den wiring or its own cord.

 Cutting accessory 

contacting a “live” wire may make exposed metal 

parts of the power tool “live” and could give the 

operator an electric shock.

12. 

Position the cord clear of the spinning acces-

sory.

 If you lose control, the cord may be cut or 

snagged and your hand or arm may be pulled into 

the spinning wheel.

13. 

Never lay the power tool down until the acces-

sory has come to a complete stop.

 The spinning 

wheel may grab the surface and pull the power 

tool out of your control.

14. 

Do not run the power tool while carrying it at 

your side.

 Accidental contact with the spinning 

accessory could snag your clothing, pulling the 

accessory into your body.

15. 

Regularly clean the power tool’s air vents.

 The 

motorʼs fan will draw the dust inside the housing 

and excessive accumulation of powdered metal 

may cause electrical hazards.

16. 

Do not operate the power tool near flammable 

materials.

 Sparks could ignite these materials.

17. 

Do not use accessories that require liquid 

coolants.

 Using water or other liquid coolants 

may result in electrocution or shock.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged 

rotating wheel. Pinching or snagging causes rapid 

stalling of the rotating wheel which in turn causes the 

uncontrolled power tool to be forced in the direction 

opposite of the wheel’s rotation at the point of the 

binding.

For example, if an abrasive wheel is snagged or 

pinched by the workpiece, the edge of the wheel that is 

entering into the pinch point can dig into the surface of 

the material causing the wheel to climb out or kick out. 

The wheel may either jump toward or away from the 

operator, depending on direction of the wheel’s move-

ment at the point of pinching. Abrasive wheels may also 

break under these conditions.

Kickback is the result of power tool misuse and/or 

incorrect operating procedures or conditions and can be 

avoided by taking proper precautions as given below.
1. 

Maintain a firm grip on the power tool and 

position your body and arm to allow you to 

resist kickback forces. Always use auxiliary 

handle, if provided, for maximum control over 

kickback or torque reaction during start-up.

 

The operator can control torque reactions or kick-

back forces, if proper precautions are taken.

2. 

Never place your hand near the rotating acces-

sory.

 Accessory may kickback over your hand.

3. 

Do not position your body in line with the 

rotating wheel.

 Kickback will propel the tool in 

direction opposite to the wheel’s movement at the 

point of snagging.

4. 

Use special care when working corners, sharp 

edges etc. Avoid bouncing and snagging the 

accessory.

 Corners, sharp edges or bouncing 

have a tendency to snag the rotating accessory 

and cause loss of control or kickback.

5. 

Do not attach a saw chain, woodcarving blade, 

segmented diamond wheel with a peripheral 

gap greater than 10 mm or toothed saw blade.

 

Such blades create frequent kickback and loss of 

control.

6. 

Do not “jam” the 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 kick-

back or wheel breakage.

7. 

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 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.

8. 

Do not restart the cutting operation in the 

workpiece. Let the wheel reach full speed and 

carefully re-enter the cut.

 The wheel may bind, 

walk up or kickback if the power tool is restarted in 

the workpiece.

9. 

Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kick-

back.

 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.

10. 

Use extra caution when making a “pocket cut” 

into existing walls or other blind areas.

 The 

protruding wheel may cut gas or water pipes, elec-

trical wiring or objects that can cause kickback.

11. 

Before using a segmented diamond wheel, 

make sure that the diamond wheel has the 

peripheral gap between segments of 10 mm or 

less, only with a negative rake angle. 

Additional Safety Warnings:

1. 

Never attempt to cut with the tool held upside 

down in a vise.

 This can lead to serious acci-

dents, because it is extremely dangerous.

2. 

Some material contains chemicals which may 

be toxic. Take caution to prevent dust inhala-

tion and skin contact. Follow material supplier 

safety data.

3. 

Store wheels as per manufacturer recom-

mendations.

 Improper storage may damage the 

wheels.
