Operating Modes - Bostitch 651 SERIES Operation And Maintenance Manual

Always disconnect air supply before making adjustments as accidental actuation may
occur, possibly causing injury.
BOSTITCH OFFERS TWO MODES OF OPERATION FOR THIS SERIES TOOL.
CONTACT TRIP:
The common operation procedure on "Contact Trip" tools is for the operator to contact the work surface to
actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work surface
is contacted. This will allow rapid fastener placement on many jobs. All pneumatic tools are subject to recoil
when driving fasteners. The tool may bounce, releasing the trip, 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.
SEQUENTIAL TRIP:
The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes
accurate fastener placement easier. The Sequential Trip allows exact fastener location without the possibility if
driving a second fastener on recoil as described under "Contact Trip". The Sequential Trip Tool has a positive
advantage because it will not accidentally drive a fastener if the tool is contacted against the work surface - or
anything else - while the operator is holding the trigger pulled.
MODE IDENTIFICATION:
Refer to Tool Operation Instructions on pages 9-10 before proceeding to use this tool.

HOW TO CHANGE OPERATING MODES:
The 651 stapler is initially locked in the sequential trip operating mode. In order to enable the mode selection
feature, the mode locking pin must be removed as shown in FIG A.
Be aware that once the mode locking pin is removed, the trigger is converted to a selectable
trigger, enabling either sequential trip or contact trip operating modes.
Always disconnect air supply: 1) Before making adjustments; 2) When servicing the tool; 3)
When clearing a jam; 4) When tool is not in use; 5) When moving to a different work area, as
accidental actuation may occur, possibly causing injury.
Selecting Contact Trip Mode: Refer to Fig A.
1) Remove mode locking pin.
2) Push in pivot pin and hold.
3) Rotate the selector 180 degrees counter-clockwise to
the contact trip position, while pushing in the pivot pin.
4) Ensure the selector is fully seated in the new position.
Always verify and be aware of tool operating
mode by inspecting the trigger before connecting
to an air supply and/or using the tool.
Selecting Sequential Trip Mode:
1) Remove mode locking pin (if installed).
2) Push in pivot pin and hold.
3) Rotate the selector 180 degrees clockwise to the
sequential trip position, while pushing in the pivot pin.
4) Ensure the selector is fully seated in the new position.
