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 can 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 trigger does 

not turn the tool on or off.

 Any tool that 

cannot be controlled with the trigger is 

dangerous and must not be used until 

repaired.

d. 

Disconnect the tool from the air 

source before making adjustments, 

doing tool maintenance, clearing 

jams, touching the safety nosepiece, 

leaving work area, loading, or 

unloading the tool.

 Such precautionary 

measures reduce the risk of injury to 

persons.

e. 

Store the tool when it is idle out of 

reach of children and other untrained 

persons.

 A tool is dangerous in the 

hands of untrained users.

f. 

Maintain the tool with care.

  A properly 

maintained tool reduces the risk of 

binding and is easier to control.

g. 

Check for misalignment or binding 

of moving parts, breakage of parts, 

and any other condition that affects 

the tool’s operation.

 If damaged, 

have the tool serviced before using.  

Many accidents are caused by poorly 

maintained tools. There is a risk of 

bursting if the tool is damaged.

h. 

Use only accessories that are 

identified by the manufacturer for 

the specific tool model.

 Use of an 

accessory not intended for use with the 

specific tool model, increases the risk of 

injury to persons.

i. 

Use only those fasteners listed in the 

Specifications chart of this manual.

  

Fasteners

 

not identified for use with this 

tool by the tool manufacturer are able to 

result in a risk of injury to persons or tool 

damage when used in this tool.

Service

a. 

Tool service must be performed only 

by qualified repair personnel.

b. 

When servicing a tool, use only 

identical replacement parts. Use only 

authorized parts.

c. 

Use only the lubricants supplied 

with the tool or specified by the 

manufacturer.

Air source

a. 

Never connect to an air 

source that is capable of 

exceeding 200 PSI.

 Over 

pressurizing the tool may 

cause bursting, abnormal operation, 

breakage of the tool or serious injury to 

persons. Use only clean, dry, regulated 

compressed air at the rated pressure or 

within the rated pressure range as 

marked on the tool. Always verify prior to 

using the tool that the air source has 

been adjusted to the rated air pressure 

or within the rated air-pressure range.

b. 

Never use oxygen, carbon dioxide, 

combustible gases or any bottled gas 

as an air source for the tool.

 Such 

gases are capable of explosion and 

serious injury to persons.

  SAVE THESE 

INSTRUCTIONS.
