TOOL USE INSTRUCTIONS
LOCKOUT MECHANISM
The lockout mechanism found on the CN nailer was designed with the user in mind. This devise will protect the
work surface from blank shots caused by the user unknowingly using a tool with the magazine empty. The lockout
also serves as a notification to reload the tool.
The lockout stops the work contact element from activating when there are four to five nails, depending on
diameter, left in the magazine. The tool remains inoperable until a new strip of nails is loaded into the magazine.
NOTE: Make sure that the magazine is completely empty of all fasteners before loading a different fastener. The
four or five fasteners left in the magazine may not be specified for the intended application.
DO NOT:
• Engage in horseplay.
DO:
• Have maintenance and repair work done by a qualified service person using
DUO-FAST authorized parts.
DO NOT:
• Modify the tool without approval of DUO-FAST.
• Tamper with or cause the work contact element to become inoperative.
• Install a female quick-disconnect on the tool. This could cause air pressure to be
retained in the tool when disconnected from the air hose. The tool could still drive
a fastener.
Read safety instructions before using the tool
AIR SYSTEM REQUIREMENTS

AIR HOSE AND FITTINGS
• The air supply hose must have a minimum working pressure of 150 PSIG or
150% of the maximum pressure, whichever is higher.
• Use a 5/16" I.D. air hose for up to 25' long. Use a 1/2" hose for up to 100'
long.
