Actuating Tool

WARNING: To reduce the risk of injury, Always wear
proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and hearing
protection [ANSI S12.6 (S3.19)] when operating
thistool.
The tool can be actuated using one of two modes:
single sequential action trigger mode and bump action
triggermode. The trigger installed on the tool as described
in the Trigger section of this manual determines the mode
ofoperation.
Sequential Action Trigger - Gray
Trigger (Fig.A)
The sequential action trigger’s intended use is for
intermittent fastening where very careful and accurate
placement isdesired.
To Operate the Nailer in Sequential Action Mode
1. Depress the contact trip firmly against the worksurface.
2. Pull thetrigger.

WARNING: A fastener will be driven each time the
trigger is pulled as long as the contact trip remains
depressed which could result in accidentaldriving.
Bump Action Trigger - Black Trigger
(Fig.A)
The bump action trigger’s intended use is for rapid fastening
on flat, stationarysurfaces.
Using the bump action trigger, two methods are available:
place actuation and bumpactuation.
To Operate the Tool Using the Place ActuationMethod
1. Push the contact trip against the worksurface.
2. Pull thetrigger.
3. Release the trigger and allow the tool to recoil off
theworkpiece.
To Operate the Tool Using the Bump ActuationMethod
1. Pull thetrigger.
2. Push the contact trip against the work surface. As long
as the trigger is pulled, the tool will drive a fastener every
time the contact trip is depressed. This allows the user to
drive multiple fasteners insequence.
