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 Staplers 1. 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. 2. 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. 3. 4. -4- SAFE HANDLING.
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.

SECTION 3: SET UP Unpacking Inventory Your Model H7677 stapler kit 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 H7677 Inventory (Figure 1) A.
Compressed Air System The Model H7677 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 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 stapler as possible.
Safety Yoke A safety yoke mechanism (bump fire) on the nose of the stapler acts as a safety device. When the trigger is pulled, the stapler will not fire until the safety yoke mechanism is depressed. Before you use your stapler for the first time, check the safety yoke mechanism to ensure proper function. To do this: 1. DISCONNECT STAPLER FROM THE AIR SUPPLY! 2. Make sure the magazine is empty and contains no staples. 3. Make sure the trigger and the safety yoke mechanism move up and down without sticking.
SECTION 4: OPERATIONS Loading When replacing staples in your Model H7677, follow these guidelines: Gauge: 18 Length: 1⁄2"–1" Capacity: 100 Crown: 1⁄4" Figure 4. Loading staples into magazine. To load your stapler: 1. DISCONNECT STAPLER FROM THE AIR SUPPLY! 2. Grip the stapler firmly, and pull the magazine pusher back until it latches in the groove as shown in Figure 3. Groove 4. Slide the staples all the way down to the nose of the stapler. 5. Release the magazine pusher by pulling back and up.
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 staple in case of deflection. Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the staple to change its path, resulting in the staple puncturing the surface of the workpiece, as shown in Figure 5.
To operate your stapler in bump fire mode: 4. 1. Push the trigger switch IN (Figure 7). Loosen the cap screws shown in Figure 8 and remove the nose cover. Nose Cover Cap Screw Figure 8. Loosening cap screws on cover. Figure 7. Trigger switch, bump fire mode. 2. Pull the trigger. 3. Press the safety yoke mechanism against your workpiece and raise it after the staple is driven. 4. Hold the trigger and repeat Step 3 to drive more staples. Clearing Jammed Staples 5.
Replacing Pistons/ORings If you use your stapler day in and day out, repair pistons are cheap insurance against wasted down time and lost profits, in the event that a piston or piston shaft becomes worn out. A replacement piston and O-ring kit, part PH7677069, may be purchased for the Model H7677. Always disconnect air from stapler whenever servicing! During maintenance, a stapler connected to air may fire accidentally, causing serious personal injury! To replace a piston: 1.
SECTION 5: MAINTENANCE Cleaning Lubricating Use a good solvent to clean the nose assembly of the stapler. Always be sure that the stapler is dry before using it again. Special oil has been included with your new Grizzly stapler to help maintain its useful life. Place two to three drops of oil in the stapler air inlet (as shown in Figure 9) before every use, or after 2 hours of continuous use. Do not allow dust, chips, sand, etc.
