TO LOAD:
➀
Insert strip(s) of nails into rear of maga-
zine. For optimum performance use SENCO
fasteners. Do not load with workpiece contact
(safety element) or trigger depressed.
➁
Pull feeder shoe back.
UNLOADING THE TOOL:
Push Tab on feeder shoe to release feeder from strip. Pull fastener strip out past sheet metal nail detainer.
Do not load with workpiece contact (safety element) or trigger depressed.
Use only genuine SENCO fasteners (see Fastener Specifications).

ACTUATION SYSTEM:
With a Sequential Actuation (Restrictive) trigger, fasteners can only be driven one way:
➀
Press the workpiece contact (safety element) against the work surface.
➁
Pull the trigger.
③
A single fastener will be driven.
④
Additional fastener drive requires both the workpiece contact and trigger be released.
TO AVOID SERIOUS INJURY FROM FASTENERS AND FLYING DEBRIS WHEN INSTALLING METAL CONNECTORS
USING THE JN SERIES NAILER:
Use only genuine Senco metal connector nails.
Metal connector nails are not designed to penetrate metal. When installing metal connectors, always place the exposed
point of the metal connector nail into the metal connector’s pre-formed hole, and orient so the nail is perpendicular to the
hole before attempting to drive a fastener.
Senco strongly recommends the use of hardened nails in the JN Series tools.
WORK CONTACT ELEMENT (JN91H1 / JN91H2):
The moveable nose, which acts as the contact trip, is in the “depressed”
position at rest to allow visibility of the nail points. When the tip of the nail is placed in the pre-punched metal connector
hole and the trigger is pulled, the moveable nose moves out from the tool to detect the work surface. If the moveable nose
does not detect the work surface close to the nose of the tool, the tool will not actuate.
WORK CONTACT ELEMENT (JN91P1 / JN91P2):
First depress the workpiece contact element against work surface, insert-
ing the probe tip into the pre-punched metal plate hole. Then pull trigger.
TO ADJUST THE DEPTH THE FASTENER IS DRIVEN: (JN91P1 AND JN91P2 ONLY)
First disconnect the air supply.
Using your thumb or index finger, rotate wheel to adjust the Depth Control safety element to
achieve desired depth.
