personal safety

a. 

Stay alert. Watch what you are do-

ing and use common sense when 

operating the tool.  Do not use the 

tool while tired or under the influ-

ence of drugs, alcohol, or medica-

tion. 

A moment of inattention while 

operating the tool increases the risk 

of injury to persons.

b. 

dress properly. do not wear loose 

clothing or jewelry. contain long 

hair. keep hair, clothing, and 

gloves away from moving parts. 

Loose clothes, jewelry, or long hair 

increases the risk of injury to persons 

as a result of being caught in moving 

parts.

c. 

avoid unintentional starting. be 

sure the switch is off before con-

necting to the air supply. 

Do not 

carry the tool with your finger on the 

switch or connect the tool to the air 

supply with the switch on.

d. 

remove adjusting keys and 

wrenches before turning the tool 

on.

  A wrench or a key that is left 

attached to a rotating part of the tool 

increases the risk of personal injury.

e. 

do not overreach. keep proper 

footing and balance at all times. 

Proper footing and balance enables 

better control of the tool in unexpect-

ed situations.

f. 

use safety equipment.

 A 

dust mask, non-skid safety 

shoes and a hard hat must 

be used for the applicable 

conditions.  Wear heavy-duty work 

gloves during use.

g. 

always wear eye protec-

tion.

  Wear ANSI-ap-

proved safety goggles.

h. 

always wear hearing 

protection when using 

the tool.

 Prolonged expo-

sure to high intensity noise 

is able to cause hearing loss.

tool use and care

a. 

Use clamps or another practical 

way to secure and support the 

workpiece to a stable platform.

 

Holding the work by hand or against 

the body is unstable and is able to 

lead to loss of control.

b. 

do not force the tool.

 Use the 

correct tool for the application. The 

correct tool will do the job better and 

safer at the rate for which the tool is 

designed.

c. 

do not use the tool if the switch 

does not turn the tool on or off.

 

Any tool that cannot be controlled 

with the switch is dangerous and 

must be repaired.

d. 

disconnect the tool from the air 

source before making any adjust-

ments, changing accessories, or 

storing the tool.

 Such preventive 

safety measures reduce the risk of 

starting the tool unintentionally.  Turn 

off and detach the air supply, safely 

discharge any residual air pressure, 

and release the throttle and/or turn 

the switch to its off position before 

leaving the work area.
