Drives full round head nails from 1-7/8" — 2-1/2" in length and from 

.092 — .099 nail shank diameter.

Sequential Actuation Trigger (also known as restrictive trigger or 

trigger fire) operates in the following a sequence - depress the safety 

element at 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 and acceptable for most applications.  

Contact Actuation Trigger (also known as dual action, bounce or 

bottom fire) operates in the following sequence- pull the trigger first and 

keep the trigger pulled while moving the tool along the work surface 

with a bouncing motion, depressing the safety element at the nose of 

the tool against the work surface where the fastener is to be driven.  This 

trigger is recommended for use by trained professionals only in high 

production or volume applications.  

Always read the Operators Manual and Safety Instructions with all tools 

to ensure proper use and safety precautions or log on to
