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 operation is dusty.
Additional Safety Instructions for Nailers 1. Hand injuries: Do not place your hands near the nail point of entry. A nail can deflect and tear through the surface of the workpiece, puncturing your hand or fingers. 2. 3. combustible gases: Never connect the nailer to pressurized oxygen or other combustible gases as a power source. Only use filtered, lubricated, and regulated compressed air.
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. Operating this nailer 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.

Set up Unpacking Inventory Your Model T20568 left our warehouse in a carefully packed box.

Compressed Air System The Model T20568 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 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 T20568, follow these guidelines: Gauge: 18 Length: 3/8" – 11⁄4" Capacity: 100 4. Slide the nails all the way down to the nose of the nailer. 5. Slide the pusher back until the catch lever locks. Operating To load your nailer: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2. Grip the nailer firmly, release the catch lever and slide the magazine pusher open, as shown in Figure 3.
3. Depress the safety nose mechanism against 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 in case of deflection. 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 4. Open the nailer nose by removing the rubber nose tip, depressing the nose release mechanism, and opening the nose cover as shown in Figure 7. A jammed nail must be cleared before using the nailer again. Nose Release Clip To clear a jammed nail from the discharge area: 1. Nose Tip DISCONNECT NAILER FROM THE AIR SUPPLY! Nose Cover 2. Release the catch lever and slide the magazine pusher back. 3. Remove the nail stick from the magazine. Figure 7. Nose opened to clear a jam. 5.
Replacing Pistons & O-Rings 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. A replacement piston and O-ring kit, part PT20568082, may be purchased for the Model T20568. 4. Open the nose cover as if to clear a jammed nail. 5. 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. 6.
CLEANING & LUBRICATION Cleaning Lubricating Use a good solvent to clean the nose assembly of the nailer. Always be sure that the nailer is dry before using it again. Pneumatic tool oil has been included with your new Grizzly nailer to help maintain its useful life. Place two to six drops of oil in the nailer air inlet (as shown in Figure 8) before every use, or after 2 hours of continuous use. Do not allow dust, chips, sand, etc.
