English NAILER OPERATION Read section titled "SAFETY"(pages 4 - 6). & DANGER • Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications. &WARNING • NEVER point tool at yourself or others in work area. • Keep fingers AWAY from trigger when not driving nails to avoid accidental firing. • Choice of triggering method is important. Please read and understand "Methods of Operation" below. • Before starting work, check the nailing operation switching device. This Hitachi nailer includes a nailing operation switching device. Before starting work, make sure that the switching device is properly set. If the switching device is not set properly, the nailer will not operate correctly. • Never place your hands or feet closer than 8 inches (200 mm) from firing head when using. • Do not drive nails on the top of other nails or with Nailer at too steep of an angle; nails can ricochet and hurt someone. • Do not drive nails into thin boards or near corners and edges of workpiece. Nails can be driven through or away from workpiece and hit someone. • Never drive nails from both sides of a wall at the same time. Nails can be driven into and through the wall and hit a person on the opposite side. • Never use Nailer which is defective or operating abnormally. • Do not use Nailer as hammer. • Disconnect air hose from Nailer when: 1) it is not in use; 2) leaving work area; 3) moving it to another location; and 4) handing it to another person. 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. Explanation of the various nailing operations 0 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. 0 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. They are: 1. Intermittent operation (Trigger fire): 2. Continuous operation (Push lever fire): (1) Intermittent operation (Trigger fire) Use the SINGLE ACTUATION MECHANISM setting. &WARNING • For intermittent operation, set the switching device to the upward position completely. (i.e. Set to SINGLE ACTUATION MECHANISM.) • 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. 0 Set the switching device to the upward position (to set to SINGLE ACTUATION MECHANISM). (Set the switching device to the upward position completely as shown in the diagram. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.) C) Position the nail outlet on the workpiece with finger off the trigger. 0 Depress the push lever firmly until it is completely depressed. C) Pull the trigger to drive a nail. C) Remove finger from the trigger. To continue nailing in a separate location, move the nailer along the wood, repeating steps 0 - C) as required. - 13 -
