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/ 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 an air source. Only use filtered, lubricated, and regulated compressed air. 3.
Never point this nailer at yourself or another person! Always pay attention to the direction this nailer 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. Read the manual before operation. Become familiar with this nailer, its safety instructions, and its operation before beginning any work.

SETUP Unpacking Inventory Your new item was carefully packaged for safe shipping. If you discover any damage after you have signed for delivery, immediately call Customer Service at (570) 5469663 for advice. After you open the nailer 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 H5527 Inventory (Figure 1) A. Carrying Case ....................................
Compressed Air System The Model H5527 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, 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 as possible.
safety nose mechanism Safety Nose Mechanism 5. Without pressing the trigger, depress the safety nose mechanism against a scrap piece of wood that is clean and free of any knots, nails, or other foreign objects. A safety mechanism on the nose of the nailer protects against accidental firing. When the trigger is pressed, the nailer will not fire until the safety nose mechanism is depressed. — If the nailer does not fire, then the safety nose mechanism is working correctly.
OPERATIONS Loading When replacing nails in your Model H5527, follow these guidelines: Gauge: 18 Length: 5⁄8" – 2" Capacity: 100 3. Pull the magazine cover back until it stops. 4. Point the nailer down and insert a stick of brad nails into the magazine, as shown in Figure 4. Make sure that the pointed ends of the nails rest in the slot at the bottom of the magazine. To load your nailer: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2.
Operating If you have not read the safety instructions in this manual, do not operate the nailer. Before you operate your nailer, place five to six drops of the included oil into the quick connect fitting where the nailer connects to the air supply. Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the nail to change its path, resulting in the nail puncturing the surface of the workpiece, as shown in Figure 5.
Clearing Jammed Nails To clear a jammed nail from the discharge area: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2. Remove the two cap screws that secure the driver guide cover to the driver guide on the nose assembly, as shown in Figure 6. Cap Screws Always disconnect air from nailer whenever clearing a jammed nail! A nailer connected to air may fire accidentally, causing serious personal injury! A jammed nail must be cleared before using the nailer again.
Replacing Pistons/ORings If you use your nailer 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. 6. Open the nose cover as if to clear a jammed nail. 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.
