This actuation design requires the release of both the trigger and safety mechanism after each fastener is driven. The selectable trigger can be set for the “CONTACT ACTUATION” firing mode as described in number 2 below. This actuation design requires the release of the safety mechanism ONLY after each fastener is driven. 1. To use the tool in the SINGLE SEQUENTIAL ACTUATION MODE depress trigger lever pivot pin (A) Fig. 24 and rotate it to position (B) and release. Note: Trigger lever pivot pin is spring loaded and held in position by locking tab (D) Fig. 24 to prevent movement during operation. To fire, grip tool firmly to maintain control, position nose of tool onto work surface, push the tool firmly against work surface to depress safety mechanism, as shown at (S) Fig. 24A, and then squeeze trigger to fire a fastener. Allow tool to recoil away from work surface as fastener is driven. This “single sequential actuation” method provides the most accurate fastener placement. -OR 2. To use the tool in the CONTACT ACTUATION MODE depress trigger lever pivot pin (A) Fig. 24 and rotate it to position (C) and release. Note: Trigger lever pivot pin is spring loaded and held in position by locking tab (D) Fig.24 to prevent movement during operation. To fire, grip tool firmly to maintain control, squeeze and hold trigger, push the tool firmly against work surface to depress safety mechanism, as shown at (S) Fig. 24A, and fire a fastener. Allow tool to recoil away from work surface as fastener is driven. If safety mechanism is allowed to recontact work surface before trigger is released an unwanted fastener will be fired. The tool will fire a fastener each time the safety mechanism is depressed. This method is known as “contact actuation” and allows very fast repetitive fastener placement. Fig. 24A S Fig. 24 AB C D 9 IMPORTANT: A trigger, which will limit the tool to “single sequential actuation” only, is available free-of-charge by calling 1-800-321-9443 in the United States and Canada or 001-731-660-9374 outside the United States and Canada, and providing tool model number, type, serial number, etc. For identification purposes: the single sequential actuation trigger is red. Disconnect tool from air supply before performing maintenance, clearing a jammed fastener, leaving work area, moving tool to another location, or handing the tool to another person. Clean and inspect tool daily. Carefully check for proper operation of trigger and safety mechanism. Do Not use the tool unless both the trigger and the safety mechanism are functional, or if the tool is leaking air or needs any other repair. The depth to which a fastener is driven is controlled by the depth adjustment knob (A) Fig. 25. The depth of drive is factory adjusted to a nominal setting. Test fire a fastener and check depth. If a change is desired, rotate the adjustment knob (A) Fig. 25. The adjustment knob has detents every 1/4 turn. Rotate the knob (A) Fig. 25 counterclockwise to increase the depth of drive, rotate the knob clockwise to decrease the depth of drive. Test fire another fastener and check depth. Repeat as necessary to achieve desired results. The amount of air pressure required will vary depending on the size of the fastener and the material being fastened. Experiment with the air pressure setting to determine the lowest setting that will consistently perform the job at hand (Fig. 25B). Air pressure in excess of that required can cause premature wear and/or damage to the tool. A rubber nose cushion (A) Fig. 26 is provided to reduce marring of the work surface. The rubber cushion can be removed, and stored inside knob (B) Fig. 27, to provide increased depth-of-drive for toe-nailing applications.

Fig. 27 A B Fig. 26 10 CLEARING A JAMMED FASTENER Disconnect tool from air supply. 1. Remove any remaining fasteners from the nailer. A. Place finger in recess (A) Fig. 28, and depress lever to release follower mechanism. B. With follower release lever depressed (A) Fig. 28, slide follower all the way to the front of the magazine. C. Depress spring (B) Fig. 29, slide fasteners to the rear, and remove all fasteners from magazine (see Fig. 19). 2. Use a pair of needle nose pliers and/or a flat screwdriver to free bent fastener from back of nosepiece. If fastener cannot be removed as described, it may be necessary to remove the magazine as follows: A. Loosen knob (A) Fig. 30 and move magazine in slotted bracket (B). B. Slide magazine back, off of nosepiece. See (B) Fig. 31. C. After clearing bent fastener (A) Fig. 31, reverse above steps to reassemble.
