SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
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 PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear a protective hair covering to contain long hair. 12. ALWAYS USE SAFETY GLASSES. Also use a face or dust mask if cutting operation is dusty.
Additional Safety Instructions for Nailers and Staplers 1. HAND INJURIES: Do not place your hands near the nail/staple point of entry. A nail/staple can deflect and tear through the surface of the workpiece, puncturing your hand or fingers. 2. COMBUSTIBLE GASES: Never connect the nailer/stapler to pressurized oxygen or other combustible gases as a power source. Only use filtered, lubricated, and regulated compressed air. 3. 4.
Never point this nailer/stapler at yourself or another person! Always pay attention to the direction this nailer/ 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 nailer/stapler can propel objects into the air, causing immediate eye damage.
SECTION 2: INTRODUCTION Foreword Contact Info We are proud to offer the Grizzly Model H7664 2-in-1 Combination Nailer/Stapler. This model is part of a growing Grizzly family of fine pneumatic tools. When used according to the guidelines set forth in this manual, you can expect years of troublefree, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction.
SECTION 3: SET UP Unpacking Inventory Your Model H7664 left our warehouse in a carefully packed box. If you discover the nailer/stapler is damaged after you have signed for delivery, please immediately call Customer Service at (570) 546-9663 for advice. After you open the nailer/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.
Compressed Air System The Model H7664 is designed to be operated at 60-100 PSI using clean, dry, regulated, compressed air. DO NOT exceed the 120 PSI maximum operating pressure for your model. Before using your new nailer/stapler, regulate the air pressure on your air compressor to the minimum PSI for your model. An in-line filter/lubricator/regulator unit, depicted in Figure 2, can be installed and should be located as close to the nailer/ stapler as possible.
Safety Yoke A safety yoke mechanism on the nose of the nailer/stapler acts as a safety device. When the trigger is pressed, the nailer/ stapler will not fire until the safety yoke mechanism is depressed. Before you use your nailer/stapler for the first time, check the safety yoke mechanism to ensure proper function. To do this: 1. DISCONNECT NAILER/STAPLER FROM THE AIR SUPPLY! 2. Make sure the magazine is empty and contains no nails/staples. 3.
SECTION 4: OPERATIONS Loading When replacing brads or staples in your Model H7664, follow these guidelines: Gauge: 18 Brad Length: 5⁄8"-2" Staple Length: 5⁄8"-15⁄8" (crown 1⁄4") Capacity: 100 Pusher Magazine Sight Window Figure 4. Loading nails into magazine. To load your nailer/stapler: 1. DISCONNECT NAILER/STAPLER FROM THE AIR SUPPLY! 2. Grip the nailer/stapler firmly, unlatch the catch lever (Figure 3), and pull the magazine pusher back completely. 4.
2. To test for proper nail/staple penetration, hold the nailer/stapler perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of nails/staples you have loaded. 3. Depress the safety yoke mechanism on your workpiece. 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 nail/staple in case of deflection.
Single/Bump Fire Operation Clearing Jammed Nails/Staples The nailer/stapler is designed to fire one nail/staple at a time, or one after another, using the safety yoke mechanism. This is known as "bump fire". A jammed nail or staple must be cleared before using the nailer/stapler again. To operate your nailer/stapler in single fire mode: To clear a jammed nail or staple from the magazine: 1. DISCONNECT THE NAILER/ STAPLER FROM THE AIR SUPPLY! 2.
To clear a jammed nail from the discharge area: 1. DISCONNECT NAILER/STAPLER FROM THE AIR SUPPLY! 2. Unlock the catch lever and pull the magazine pusher back completely. 3. Remove the nail/staple stick from the magazine. 4. Loosen the cap screws shown in Figure 7 and remove the cover with a 3mm hex wrench. Dislodge the jammed nail/staple with a pair of needle nose pliers. 5. Secure the cover with the cap screws removed in Step 4.
6. Open the nose cover as if to clear a jammed nail/staple. 7. Watch the discharge area and push the top of the piston with your finger. You will see the piston shaft slide down the discharge area. 8. With a long flathead screwdriver or similarly shaped tool, push the piston shaft back inside the nailer/stapler until you can grip the piston head and remove it from the cylinder. (Be careful not to scratch the discharge area when pushing the piston shaft with the screwdriver.) 9.
SECTION 5: MAINTENANCE Cleaning Lubricating Disconnect the nailer/stapler from the air supply before cleaning. Use a good solvent to clean the nose assembly of the nailer/stapler. Always be sure that the nailer/stapler is dry before using it again. Pneumatic tool oil has been included with your new Grizzly nailer/stapler to help maintain its useful life. Place two to three drops of oil in the nailer/stapler air inlet (as shown in Figure 8) before every use, or after 2 hours of continuous use.
