SENCO's Trigger Systems 
Sequential Actuation Trigger (also known as restrictive trigger or trigger fire) operates 
by following a sequence - depress the safety element on the nose of tool against the work 
surface then pull the trigger.  After each fastener is driven, release the trigger and lift the 
tool off the work surface before starting the sequence again.  This trigger is recommended 
for most applications.  
Contact Actuation Trigger (also known as dual action, bounce or bottom fire) 
operates by keeping the trigger pulled while moving the tool along the work surface with 
a bouncing motion, depressing the safety element on the nose of the tool against the 
work surface where the fastener is to be driven.  The trigger can be pulled either before or 
after depressing the safety element.  This trigger is recommended for use by trained 
professionals only in high production or volume applications.  
Both trigger systems are available, FREE OF CHARGE, for most SENCO tools.  Choose 
the right trigger system for your specific needs!
Always read the Operators Manual and Safety Instructions with all tools to ensure proper 
use and safety precautions.  Also, log on to www.senco.com or call 1-800-543-4596 for
