NOTE: For better performance, install a 3/8 inch quick plug (1/4 inch NPT threads) with an inside diameter of 0.315 inch (8 mm) on the nailer and a 3/8 inch quick coupler on the air hose. 1. With ON/OFF switch in OFF position, plug compressor into electrical outlet. 2. Close pressure regulator by turning all the way to the left. Turn compressor ON and let it pump all the way up to automatic shut-off pressure. 3. Attach air hose to regulator outlet. Adjust pressure regulator by turning to the right so that outlet pressure is between 70 psi to 120 psi. 4. Load fasteners into nailer (See Loading/Unloading the Nailer section on page 11). 5. Point the nailer in a safe direction while attaching to air hose. 6. Nailer is ready for use. You may need to adjust outlet pressure to achieve proper fastener depth.

Choose which type of fastener you want to use for you project. Additional fasteners can be found at major home centers. Loading the Tool 1. Load strips of fasteners into the slot in the rear of the magazine. Make sure that the nails are placed into tool at the proper orientation. 2. Press pusher bypass button and drag pusher over nail clip. Release pusher. 3. Reconnect tool to air supply. Unloading the Tool 1. Always unload all fasteners before removing tool from service. 2. Pull pusher back away from nail clip. Press pusher bypass button and allow pusher to ride over remaining nails. 3. Hold tool upright so nails will slide backwards toward magazine slot. 4. Remove nails. Adjustin g Th e Nail Penetration The CHN70899 is equipped with an adjustable depth of drive feature. This allows the user to determine how deep a fastener will be driven into the work surface. 1. Adjust the operating pressure to a pressure which will consistently drive the fasteners. Do not exceed the maximum operating pressure of 120 psi. 2. Pull red pin out. Twist Work Contact Element (WCE) 1/4 turn as shown. Release red pin. See Figure 10. 3. Move WCE back and forth to the extent desired. Move the WCE toward the tool to increase nail depth. Move WCE away from tool to reduce nail depth. See Figure 11. 4. Twist WCE 1/4 turn back to its original position as shown. See Figure 12. 5. Make sure that the trigger and WCE move freely up and down without binding or sticking after each adjustment.

Failure to know the operational mode could result in death or serious injury. This nailer may be operated in the “Sequential” mode (as supplied by the manufacturer) or “Bump” mode. The tool may be converted from one mode to the other by firmly pressing the conversion switch from one position to the other. Press the conversion switch on the “ ” side to activate Sequential Mode. Press the conversion switch on the “ ” side to activate Bump Mode. Press either side to the middle position to activate the Safety Lockout Mode. Sequential Mode This method is recommended when precise nail placement is required. Operation in this mode requires trigger to be pulled each time a nail is driven. Nailer can be actuated by depressing the Work Contact Element (WCE) against work surface followed by pulling the trigger. The trigger must be released after each fastener is driven to allow tool to reset. Since the tool can only be actuated by first removing the finger from the trigger, this is considered to be a more restrictive mode of operation, suitable for less experienced users.

This is intended to allow the user to change the direction of the exhaust. Simply twist the deflector to any direction desired. Installin g No-Mar Tip 1. Disconnect air supply from nailer. 2. Remove no-mar tip from storage post. 3. Remove retaining ring from no-mar tip. 4. Carefully place no-mar tip over the end of work contact element. Posi...
