AIR SOURCE

TERMINOLOGY

28.DANGER: Do not use oxygen, com- bustible gases or bottled gases as a power source for this tool. The tool will explode and cause death or serious injury.

29.Never connect to an air source that is capable of exceeding 200 psi. Over pressurizing the tool may result in burst- ing, 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. Prior to using the tool, always verify that the air source has been adjusted to the rated air pressure or within the rated air-pressure range. Air compressors should comply with ANSI B19.3.

Actuate

To cause movement of the tool component(s) intended to drive a fastener.

Actuation System

The use of a trigger, workpiece contact and/or other operating control, separately or in some combination or sequence, to actuate the tool.

• Single sequential actuation

Fastener

A staple, pin, brad, nail, or other fastening device which is designed and manufactured for use in the tools.

Jam

An obstruction in the feed or drive areas of the tool.

Workpiece Contact

SPECIFIC SAFETY INSTRUCTIONS

An actuation system that requires the

workpiece contact and then the trigger

to be activated in a specific sequence

An operating control element on the tool intended to be activated by the workpiece to be fastened.

1.Use air supply hoses with a minimum working pressure rating of 200 psi.

2.Use pressure regulators to limit the air pressure supplied to the tool. Set the regulators to no more than 120 psi.

3.Install only hose couplings that will allow all pressure to be removed from tool when disconnected from the source. If the wrong fitting is installed, pressure may remain in the tool after disconnection, allowing it to drive a fastener, possibly causing injury.

4.Prior to each use, check workpiece contact and trigger for correct op- eration. Do not disassemble or clamp parts of the workpiece contact, trigger, or driving mechanism. This will cause unexpected actuation, resulting in seri- ous injury.

5.Never point the discharge area of the tool at any body parts or at other peo- ple. Always assume the tool is loaded and capable of driving a fastener.

6.Do not actuate the tool into free space. Do not engage in horseplay. The discharged fasteners are projectiles capable of causing serious injury.

7.When using the tool, ensure the workpiece contact is securely placed on the workpiece. Hold the tool firmly and be prepared for the recoil.

8.Do not remove, tamper with, or otherwise cause the tool operating controls to become inoperable. This will cause unexpected actuation, result- ing in serious injury.

9.Do not operate a tool if any portion of the tool operating controls is inoper- able, disconnected, altered, or not work- ing properly. This will cause unexpected actuation, resulting in serious injury.

10.Always keep hands and body away from discharge area of the tool. Never attempt to clear a jammed workpiece contact by grasping the discharge area of the tool. Fasteners discharged from tool can cause serious injury if they contact hands or body.

11.Do not drive fasteners close to the edge of the workpiece. Fasteners can slip off corners and edges or penetrate through thin material, making them projectiles capable of causing serious injury.

12.Use the tool only for the intended purpose. Do not abuse the tool. Do not use as a hammer, stamp or engrave information onto parts, drop or impact the tool or otherwise apply excess force to the tool in use. Do not mount the tool to stands or modify it for stationary use.

13.Do not carry tool by the air hose. Only carry the tool by the handle with your finger off of the trigger.

14.Do not use this tool without the safety warning label in place. If the label is damaged or missing, contact MILWAUKEE for a free replacement.

 

to drive a fastener. Additional actuation

 

can occur when the trigger is released

 

and reactivated.

Contact actuation

 

An actuation system that requires the

 

workpiece contact and the trigger to be

 

activated in any sequence to drive a

 

fastener. Additional actuation can occur

 

when either the workpiece contact or the

 

trigger is released and reactivated.

Selective actuation

 

An actuation system that allows selec-

 

tion of actuation systems: single se-

 

quential actuation or contact actuation.
