DANGER: Do not use oxygen, carbon dioxide, high-pressure compressed gas or bottled gases as the power source for this tool. The tool will explode and serious personal injury could result. • The air tool operates on compressed air at pressures from 60 to 100 PSI. • Never connect the tool to air pressure which could potentially exceed 200 PSI. Use only clean, dry, regulated air within rated range as marked on tool. Air Delivery Required: 0,85 SCFM @ 90 PSI (30 shots per minute), WARNING: Keep hands and body away from discharge area of tool when connecting air supply, Always disconnect tool from air supply when servicing or adjusting tool and when tool is not in use, • Air operated tools require clean, dry, lubricated compressed air to ensure top performance, low maintenance and long life. Figure I - Air Supply Line LOADING Refer to Figures 2, 3 & 4 (page 4). WARNING: Disconnect tool from air supply. Do not load tool until you are ready to use it. Do not pull trigger or depress contact trip while loading tool. Always load with nose of tool pointing away from you and others. Always wear safety goggles that comply with United States ANSI Z87.1. NOTE: For best results, use Sears fasteners only. NAILING OPERATION Depress latch and slide magazine cover open (see Figure 2). Refer to Figures 5, 6, 7 & 8 (pages 4 and 5). WARNING: Read and follow all safety rules and operating instructions in this manual and on warning label of tool before using this tool. Keep this manual with the tool. WARNING: Do not use this tool without safety warning label. If label is missing, damaged or unreadable, contact Sears to obtain a new label. WARNING: Never operate tool unless contact trip is in contact with workpiece. Do not operate tool without fasteners or damage to tool may result. Never fire fasteners into the air because fasteners may injure operator or others and damage to tool may result. Perform "Safety Mechanism Check" as described in the Maintenance section (see page 6) prior to first use of tool and on a daily basis thereafter. Figure 2 - Open Magazine The tool is equipped with a rotating switch that can be set to rapid-fire or single-fire mode (see Figure 5). When the switch is set to single-fire mode, the tool will not drive a second fastener until the trigger is fully released and pulled again. Insert fasteners into magazine. Position fasteners at bottom of magazine with head towards top of tool (see Figure 3). • When the switch is rotated to rapid-fire drive fasteners continuously. A fastener time the contact trip is pressed against long as the trigger is maintained in the mode, the tool can will be fired each the workpiece, as pulled position. Figure 3 - Load Magazine Slide magazine cover forward over magazine until latch snaps into place, locking magazine cover (see Figure 4). Figure 5 - Push and rotate switch to select Operation Mode SINGLE-FIRE OPERATION: • The air tool is equipped with a contact trip safety mechanism that disables tool unless contact trip is pushed against work. To drive a fastener hold body firmly and press contact trip on workpiece where fastener is to be applied. Pull trigger to drive fastener into workpiece. To fire a second fastener lift the tool from the workpiece, release the trigger and then repeat the above sequence. RAPID-FIRE OPERATION: • Figure 4 - Close Magazine 4 The tool can also be operated by holding trigger depressed and pushing contact trip against workpiece. A fastener will be driven each time the contact trip is pushed against the workpiece. This operating procedure provides rapid-fire fastener driving. Never operate tool unless contact trip is in contact with workpiece. LOAD INDICATOR WARNING: All air power fastening tools recoil when operated. This recoil is caused by rapid driving of the fastener. Tool may bounce from recoil causing a second unwanted fastener to be driven. Reduce tool bounce by holding tool firmly in hand and pressing tool gently against workpiece. Let the tool do the work. This will allow recoil of tool to bounce tool away from workpiece preventing the driving of second fastener. The tool is equipped with a load indicator.The load indicator (colored red) will be visible through the magazine cover window when there are no fasteners in the magazine. CONTACT TRIP ADJUSTMENT The contact trip may be adjusted up or down to vary the depth of the fastener in the workpiece. To adjust, rotate depth control knob (see Figure 6) to raise or lower contract trip to desired setting. Figure 8 - Load Indicator OPERATING PRESSURE • Use only enough air pressure to perform the operation. Air pressure in excess of that which is required will make the operation inefficient and may cause premature wear or damage to the tool. • Determine minimum air pressure required by driving some test fasteners into the workpiece. Set air pressure so that test fasteners are driven down flush with the work surface. Fasteners driven too deep may damage workpiece. Figure 6 - Setting Depth Control CONTACT TRIP PAD The tool is equipped with a contact trip pad (see Figure 7) that prevents marring of finished surfaces by the contact trip during normal operation. Pad can be removed and stored on the storage sleeve located on the end cover of the magazine, Hex wrench is also stored on the magazine. COLD WEATHER OPERATION CAUTION: Do not store in cold environment. Frost or ice could form inside tool affecting operation and damaging tool. Use a cold temperature lubricant, such as ethylene glycol, when operating tool in freezing temperatures. Refer to Figure 9 (page 8). LUBRICATION This is an oilless tool. No lubrication is necessary. MAGAZINE AND PISTON-RAM • Keep magazine and nose of tool clean and free of any dirt, lint or abrasive particles. The tip of the ram (Fig. 9, No. 11) can become dented or rounded over time. • Figure 7 - Storing Contact Trip Pad and Wrench 5 Square off the tip of the ram with a clean, fine hand file to extend the life of the ram and tool. Fastener firing will be more consistent if the ram tip is kept clean and square. SAFETY MECHANISM CHECK Inspect contact trip safety mechanism daily for proper operation. Do not operate tool if mechanism is not operating properly. With the red push-button switch in the rapid-fire mode, perform the following procedures to test safety mechanism: • Leave trigger untouched while pushing contact trip into workpiece. Tool must not fire. • Pull trigger while contact trip is clear of work and pointed away from operator and others. Tool must not fire. Depress and hold trigger. Push contact trip against work where fastener is needed. The tool should drive only one fastener each time the contact trip is pushed against workpiece. If contact trip mechanism does not operate properly, repair tool immediately through Sears Service Center. Replace any damaged or missing parts. Use the parts list to order parts. REBUILD KITS Rebuild kits are available as spare parts, (see page 9), Tools should be rebuilt if tool fails to operate properly after extended use. See troubleshooting to determine required replacement parts. Disconnect tool from air supply before attempting repair or adjustment, NOTE: When replacing O-rings or cylinder, lubricate with grease before assembly. 6 SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION Trigger cap leaks air 1.
