Note: This framing nailer is shipped
with the BLACK single cycle mode
trigger installed.
Always know the
operational
mode of the nailer before using.
Failure to know the operational
mode could result in death or seri-
ous personal injury.
Operational Modes
This stick framing nailer may be operat-
ed in the “Single Cycle” or the “Bottom
Trip” mode. The nailer is delivered in
the single cycle mode. A separate ‘red’
trigger for “Bottom Trip” mode is
included with tool as an accessory.
SINGLE CYCLE MODE
When the black trigger is installed,
nailer is in single cycle mode. This
method is recommended when precise
nail placement is required. Operation
in this mode requires trigger to be
pulled each time a nail is driven. Nailer
can be actuated by depressing the
Work Contact Element (WCE) against
work surface followed by pulling the
trigger.
The trigger must be released after each
fastener is driven to allow tool to reset.
Since the tool can only be actuated by
first removing the finger from the trig-
ger, this is considered to be a more
restrictive mode of operation, suitable
for less experienced users.
BOTTOM TRIP MODE
When the red trigger is installed, the
nailer is in bottom trip mode. This
method is recommended when less
precise nail placement is required.
Operation in this mode requires trigger
to be depressed with nailer off of the
work surface. Then, the nose of the
nailer is tapped against the work sur-
face causing a nail to be driven.
!
WARNING
Each time the Work Contact Element is
depressed, a nail is driven into the
work surface. Extreme care should be
taken because a nail will be driven
when the WCE is pressed against any
surface.
Since the tool can be actuated without
removing the finger from the trigger,
this is considered to be a less restrictive
mode, suitable for more experienced
users.
MODE CONVERSION
To convert the tool from one mode to
the other:
1. Remove o-ring on the side of trig-
ger pin.
2. Remove trigger pin, trigger, and
trigger spring.
3. Switch out only the trigger.
4. Replace trigger spring, trigger, trig-
ger pin, and o-ring.
Do not attempt to modify the trigger
components in any manner and do not
attempt to use any other trigger com-
ponents other than those intended for
this tool.
See the tool manual for further Safety
and Operation information.
