Required Daily Testing

Contact Actuation Operation

1.Grip the handle ﬁrmly.

2.Pull and hold the trigger.

3.Push the tool against the work surface, compressing the workpiece contact to drive the fastener. The tool will recoil away from the workpiece as the fastener is driven.

NOTE: Contact Actuation will also work by ﬁrst compressing the workpiece contact, then pulling the trigger.

Setting the Air Pressure and Depth of Drive

The amount of air pressure required will depend on the size of the fastener and the workpiece material.

WARNING

Know what is behind your workpiece. A fastener could travel through the workpiece and out the other side,

7.To ﬁne-tune the depth of drive, discon- nect the air supply and lay the tool on its side and point the nose of the tool away from yourself and others. Remove fastener strip. Turn the depth selector left or right to increase or decrease the driving depth.

8.Reload fastener strip according to "In- stalling Fastener Strips".

9.Drive a test fastener and repeat step 7 and 8 until desired depth is reached.

Reload Indicator

striking a bystander and causing se- rious injury. Lower the air pressure

To indicate that the magazine is almost empty of fasteners (about 4-5 left), the work- piece contact will not compress, preventing operation under usual pressure. Install more fasteners to continue working.

WARNING

NEVER wedge or hold back the work- piece contact mechanism during operation of the tool. Never attempt to clear a jammed workpiece contact by grasping the discharge area of the tool. Doing so could result in serious injury.

To avoid serious injury, do not attempt to prevent the recoil by holding the tool too ﬁrmly against the work. Keep face and body away from the tool. During normal use, the tool will recoil immediately after driving a fastener. This is a normal function of the tool. Restriction to the recoil can result in a second fastener being driven when the tool is in Contact Actuation mode. Grip the handle ﬁrmly, let the tool do the work, and do not place a second hand on top of the tool or near exhaust.

and/or depth of drive to prevent the fastener from being pushed all the way through the workpiece.

1.Lay the tool on its side and point the nose of the tool away from yourself and others.

2.Disconnect the air supply from the tool and remove fastener strip.

3.Set the depth of drive adjustment to the middle of its range.

4.Reload fastener strip according to "In- stalling Fastener Strips".

Fig. 6

Set to middle of range

5.Begin testing the depth of drive by driv- ing a test fastener into the same type of workpiece material used for the actual job using an air pressure of 90-95 psi.

6.Raise or lower the air pressure to ﬁnd the lowest setting that will drive the fastener consistently. Do not exceed 120 psi.

NOTE: It may be possible to achieve the desired depth with air pressure adjust- ments alone. If ﬁner adjustments are needed, use the depth of drive adjust- ment.

WARNING

To reduce the risk of injury to your- self and others, test the tool before beginning work each day or if the tool is dropped, received a sharp blow, been run over, etc. Complete the following checklist IN ORDER. If the tool does not work as it should, contact a MILWAUKEE service facil- ity immediately.

Always point tool away from yourself and others.

1.Disconnect the air supply from the tool and remove fastener strip.

2.Check all screws, bolts, nuts, and pins on the tool. Any loose fasteners must be tightened.

3.Pull back the fastener pusher on the magazine (to override the Reload Indi- cator) and press the workpiece contact against a workpiece. It must move smoothly.

4.With the workpiece contact pressed against the workpiece, pull the trigger. It must move smoothly.

5.Connect the air supply (at 70 psi) to the tool. DO NOT load a fastener strip.

6.Select the Single Sequential Actuation Operation. Air must not leak from the tool.

Without pulling the trigger, pull back the fastener pusher on the magazine (to override the Reload Indicator) and press the workpiece contact against a workpiece. The tool must not operate.

Holding the workpiece contact away from the workpiece, pull back the fastener pusher on the magazine (to override the Reload Indicator). Pull and hold the trigger for 5 seconds. The tool must not operate.

Continue to pull and hold the trigger and push the workpiece contact against a workpiece. The tool must not operate.

Without pulling the trigger, pull back the fastener pusher on the magazine (to override the Reload Indicator) and press the workpiece contact against a workpiece. Pull the trigger. The tool must operate.

Release the trigger. The driver must move up.

7.Select the Contact Actuation Opera- tion.

Holding the workpiece contact away from the workpiece, pull back the fastener pusher on the magazine (to override the Reload Indicator) and pull the trigger. The tool must not operate.

Continue to pull and hold the trigger and push the workpiece contact against a workpiece. The tool must operate.

8.If all previous tests work properly, set the tool for your work. Select the operation and load fastener strips.

9.Set the depth of drive according to the "Setting the Air Pressure and Depth of Drive" section.

10.If all tests operate properly, the tool is ready for use. Repeat these tests before use each day or if the tool is dropped, received a sharp blow, been run over, jammed, etc.
