English NOTE: Please set depth adjustment dial to Maximum depth when using steel caps (washers). (Refer to ADJUSTING THE NAILING DEPTH on page 18). If this is not done, the finish may be poor after nailing. This Hitachi nailer is equipped with a nailer operation switching device. Use SINGLE ACTUATION MECHANISM or CONTACT ACTUATION MECHANISM in accordance with the work to be performed. completely as shown in the diagram. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.) 2 Position the nail outlet on the workpiece with finger off the trigger. 3 Depress the push lever firmly until it is completely depressed. 4 Pull the trigger to drive a nail. 5 Remove finger from the trigger. To continue nailing in a separate location, move the nailer along the wood, repeating steps 2 - 5 as required. Explanation of the various nailing operations ⅜ SINGLE ACTUATION MECHANISM (SINGLE SEQUENTIAL ACTUATION MECHANISM) : First, press the push lever against the workpiece; next, pull the trigger to drive the nail. First, pull the trigger; next, press the push lever against the workpiece to drive the nail. After nailing once, nailing will not be possible again until the trigger is released and pressed again. ⅜ CONTACT ACTUATION MECHANISM : First, press the push lever against the workpiece; next, pull the trigger to drive the nail. First, pull the trigger; next, press the push lever against the workpiece to drive the nail. If the trigger is held back, a nail will be driven each time the push lever is pressed against the workpiece. METHODS OF OPERATION This Nailer is equipped with the push lever and does not operate unless the push lever is depressed (upward position). There are two methods of operation to drive nails with this Nailer. 1 Upward position Switching device Trigger 2 3 They are : 1. Intermittent operation (Trigger fire) : 2. Continuous operation (Push lever fire) : (1) Intermittent operation (Trigger fire) Use the SINGLE ACTUATION MECHANISM setting. Push lever (2) Continuous operation (Push lever fire) Using CONTACT ACTUATION MECHANISM WARNING ⅷ Unlike the FULL SEQUENTIAL ACTUATION MECHANISM, please note that the SINGLE ACTUATION MECHANISM of this Hitachi nailer will drive a nail each time the push lever is pressed against the wood as long as the trigger is pressed. ⅷ For intermittent operation, set the switching device to the upward position completely. (i.e. Set to SINGLE ACTUATION MECHANISM.) ⅷ To avoid double firing or accidental firing due to recoil. 1) Set the switching device to SINGLE ACTUATION MECHANISM. 2) Pull the trigger rapidly and firmly. 1 Set the switching device to the upward position (to set to SINGLE ACTUATION MECHANISM). (Set the switching device to the upward position WARNING ⅷ To avoid double firing or accidental firing due to recoil. 1) Do not press the nailer against the wood with excessive force. 2) Separate the nailer from the wood as it recoils after nailing. 1 Set the switching device to the downward position (to set to CONTACT ACTUATION MECHANISM). (Set the switching device to the downward position completely as shown in the diagram. Otherwise, it will not operate properly.) 2 Pull the trigger with the Nailer off the workpiece. 3 Depress the push lever against the workpiece to drive a nail. 4 Move the Nailer along the workpiece with a bouncing motion. Each depression of the push lever will drive a nail. - 16 -
