English PREVENTIVE MECHANISM FOR UNLOADED OPERATION The machine employs a preventive mechanism for unloaded operation. The machine enters a state where the push lever stopper runs into the upper part of the push lever and the push lever cannot be pushed up. This takes place when the magazine is not loaded with nails or when the remaining number of nails becomes less than 5 (This differs by the type of nail). Load the nails immediately if you come across with such a condition during operation. Push Lever Stopper 5 1 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.) 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. Push Lever 1 Upward position Switching Device CAUTION ⅷ Use caution not to throw the push lever tip onto wood and the like while the push lever stopper is in the upper part of the push lever. Trigger METHODS OF OPERATION This Nailer is equipped with the push lever and does not operate unless the push lever is depressed (upward 4 position). There are two methods of operation to drive nails with this Nailer. 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. 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. Push Lever (2) Continuous operation (Push lever fire) Using CONTACT ACTUATION MECHANISM 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. - 14 -
