Cordless grinder safety warnings

Safety warnings common for grinding, sanding, 

wire brushing, or cutting-off operations:

1. 

This power tool is intended to function as a 

grinder, sander, wire brush, or cut-off tool. 

Read all safety warnings, instructions, illus-

trations and specifications provided with this 

power tool.

 Failure to follow all instructions listed 

below may result in electric shock, fire and/or 

serious injury.

2. 

Operations such as polishing or hole cutting 
are not to be performed with this power tool.

Operations for which the power tool was not 

designed may create a hazard and cause per

-

sonal injury.

3. 

Do not convert this power tool to operate in 

a way which is not specifically designed and 

specified by the tool manufacturer.

 Such a con-

version may result in a loss of control and cause 

serious personal injury.

4. 

Do not use accessories which are not spe-

cifically designed and specified by the tool 

manufacturer.

 Just because the accessory can 

be attached to your power tool, it does not assure 

safe operation.

5. 

The rated speed of the accessory must be at 
least equal to the maximum speed marked on 
the power tool.

 Accessories running faster than 

their rated speed can break and fly apart.

6. 

The outside diameter and the thickness of your 
accessory must be within the capacity rating 
of your power tool.

 Incorrectly sized accessories 

cannot be adequately guarded or controlled.

7. 

The dimensions of the accessory mounting 

must fit the dimensions of the mounting hard

-

ware of the power tool.

 Accessories that do not 

match the mounting hardware of the power tool 

will run out of balance, vibrate excessively and 

may cause loss of control.

8. 

Do not use a damaged accessory. Before each 
use inspect the accessory such as abrasive 
wheels for chips and cracks, backing pad for 
cracks, tear or excess wear, wire brush for 
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install 
an undamaged accessory. After inspecting and 
installing an accessory, position yourself and 
bystanders away from the plane of the rotating 
accessory and run the power tool at maximum 
no-load speed for one minute. 

Damaged acces-

sories will normally break apart during this test 

time.

9. 

Wear personal protective equipment. 
Depending on application, use face shield, 
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors, 
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.

The eye protection must be capable of stopping 

flying debris generated by various applications. 

The dust mask or respirator must be capable 

of filtrating particles generated by the particular 

application. Prolonged exposure to high intensity 

noise may cause hearing loss.

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 accessory 

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 tool may contact hidden 
wiring.

 Contact with a "live" wire will also make 

exposed metal parts of the power tool "live" and 
could give the operator an electric shock.

12. 

Never lay the power tool down until the acces-
sory has come to a complete stop.

 The spinning 

accessory may grab the surface and pull the 

power tool out of your control.

13. 

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.

14. 

Regularly clean the power tool’s air vents.

 The 

motor’s fan will draw the dust inside the housing 
and excessive accumulation of powdered metal 

may cause electrical hazards.

15. 

Do not operate the power tool near flammable 

materials.

 Sparks could ignite these materials.

16. 

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, backing pad, brush or any other acces

-

sory. Pinching or snagging causes rapid stalling of the 

rotating accessory which in turn causes the uncon

-

trolled power tool to be forced in the direction opposite 

of the accessory’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 with both hands on the 

power tool and position your body and arms 
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 kickback 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 the area where 
power tool will move if kickback occurs.

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.
