Safety Instructions For Pneumatic Tools 10. USE PROPER AIR HOSE for the tool. Make sure your air hose is in good condition and is long enough to reach your work without stretching. 11.

Wear a protective hair covering to contain long hair. 12. ALWAYS USE ANSI APPROVED SAFETY GLASSES.
Additional Safety Instructions for Staplers 1. 2. 3. 4. -2- HAND INJURIES: Do not place your hands near the staple point of entry. A staple can deflect and tear through the surface of the workpiece, puncturing your hand or fingers. COMBUSTIBLE GASES: Never connect the stapler to pressurized oxygen or other combustible gases as a power source. Only use filtered, lubricated, and regulated compressed air.
Never point this stapler at yourself or another person! Always pay attention to the direction this stapler is pointed. Use this tool with respect and caution to lessen the possibility of operator or bystander injury. Ignoring this warning may result in serious personal injury. Operating this stapler can propel objects into the air, causing immediate eye damage. To protect yourself, always wear American National Standards Institute (ANSI) approved safety glasses or goggles when operating this equipment.
INTRODUCTION Foreword We are proud to offer the Grizzly Model H7947/H7948 16 Gauge Stapler. This stapler is part of a growing Grizzly family of fine pneumatic tools. When used according to the guidelines in this manual, you can expect years of trouble-free, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction. The specifications and photographs in this manual represent Model H7947/H7948 as supplied when this manual was prepared.
SETUP Unpacking Inventory Your Model H7947/H7948 left our warehouse in a carefully packed box. If you discover the stapler is damaged after you have signed for delivery, please immediately call Customer Service at (570) 5469663 for advice. After you open the stapler box, you should find the following. Save the containers and all packing materials for possible inspection by the carrier or its agent. Otherwise, filing a freight claim can be difficult. Model H7947/H7948 (Figure 1) A. Stapler .............
Compressed Air System The Model H7947/H7948 is designed to be operated at 70–110 PSI using clean, dry, regulated, compressed air. DO NOT exceed 120 PSI. An in-line filter/lubricator/regulator unit, depicted in Figure 2, can be installed and should be located as close to the stapler as possible.
Testing Safety Nose Mechanism A safety mechanism (bump fire) on the nose of the stapler protects against accidental firing. This mechanism is activated when staples are loaded into the magazine. The stapler will not fire when the trigger is pulled until the safety nose is fully depressed. Before you use your stapler for the first time, check the safety nose mechanism to ensure proper function. 5.
OPERATIONS Loading Staples 3. With the pusher locked at the rear of the magazine, insert a strip of staples into the magazine as shown in Figure 4. Use staples meeting the specifications listed for your stapler on Page 4 of this manual. To load staples in your stapler: 1. DISCONNECT STAPLER FROM THE AIR SUPPLY! Point the stapler away from you and others when connecting the air supply. The stapler can cycle and discharge a staple when the air supply is connected.
Rotating Exhaust Cover Using the Stapler The exhaust cover rotates as needed to direct the exhaust away from you. To rotate the exhaust cover: 1. Use the 4mm hex wrench to loosen the exhaust cover cap screw as shown in Figure 5. Read the manual before operation. Become familiar with these staplers, their safety instructions, and operation before beginning any work. Serious personal injury may result if safety or operational information is not understood or followed. Figure 5.
4. Before pulling the trigger, make sure your free hand and other body parts are positioned out of the way of a potential path of a staple in case of deflection (illustrated below in Figure 6). Adjusting Depth Changing the depth of staple penetration is done by changing the position of the adjusting block on the contact arm. To adjust the depth: 1. DISCONNECT STAPLER FROM THE AIR SUPPLY. 2. Use a 4mm hex wrench to loosen the depth adjustment cap screw on the contact arm as shown in Figure 7. Figure 6.
— If you want to increase the staple depth, then move the adjusting block up, toward the nose as shown in Figure 9. 2. Unlatch the nose cover as shown in Figure 10. Adjusting Block Up Nose Cover Latch Figure 10. Unlatching the nose cover. Figure 9. Moving the adjustment block up. 4. Tighten the depth adjustment cap screw. 3. Open the nose cover as shown in Figure 11. 5.
Replacing Pistons/O-Rings 4. Push the top of the piston down with your finger as far as it will go; this will push the piston driver into the nose of the stapler. If you need to replace piston parts in your stapler, you can purchase a piston repair kit from Grizzly: call 1-800-523-4777. 5. Open the nose cover of the stapler to reveal the piston driver. The Piston Repair Kit part number for Model H7947 is PH7947081; the Piston Repair Kit part number for Model H7948 is PH7948081.
CLEANING & LUBRICATING Cleaning Lubricating Use an automotive grade solvent such as Sprayway C-60 ® (G2544 in the Grizzly catalog) to clean the nose assembly of the stapler. Always be sure that the stapler is dry before using it again. Special pneumatic tool oil has been included with your new Grizzly stapler to help maintain its useful life. Place two to six drops of oil in the stapler air inlet (as shown in Figure 13) every two hours of continuous use.
