CONTACT ACTUATION MODE
The common operating procedure on "Contact Actuation Mode" or "Bump Mode" tools is for the operator to
actuate the safety yoke while keeping the trigger pulled, thus driving a fastener each time the work is contacted.
This will allow rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly. All
pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the safety yoke and
if unintentionally allowed to re-contact the work surface with the trigger still actuated (finger still holding the
trigger pulled) an unwanted second fastener will be driven.
Warning: Tools must NOT be used in Contact Actuation Mode where changing from one working
position to another involves the use of ladders, stairs or similar structures such as roofs
SELECTING THE ACTUATION MODE (Fig 14-15):
To ensure safety, the user should lock the trigger (see Trigger Lockout Control above) before changing the trigger
system. To change the actuation mode, rotate the switch in the counterclockwise direction. The switch will lock
automatically when the indicating arrow is pointing down to the 3 nail icon stamped into the tool frame (Contact
Actuation Mode) or to a single nail icon stamped in the tool frame (Sequential Actuation Mode). Unlock the trigger
to resume tool operation.
UTILITY HOOK INSTALLATION (Fig 16-18):
These tools include an additional utility hook suitable for storage and temporary hanging of the tool.
Warning: Always disconnect tool from air supply before making adjustments or before attempting any part
assembly or disassembly.
1. Make sure sequential actuation mode is selected (See Actuation Mode above)
2. Depress the utility hook release button on the hook body (Fig 16)
3. Slide the utility hook into the hook attachment slot. (Fig 17)
4. Release the utility hook release button and check to ensure that the hook is locked in position. (Fig 18)
m WARNING! Never use the utility hook with the contact actuation mode.
HEX WRENCH STORAGE - (Fig 19)
A hex wrench for servicing the nailer is stored within the belt hook.
