Jam Clearing
Follow the Jam clearing procedure when the
error state shows the following indicator (RED)
(ORANGE), or the tool no longer fires correctly.
1. After the tool indicates that there is a jam,
remove the battery from the nailer.
2. Remove the magazine, all fasteners, as well
as the Nosepiece.
Note: Jams can be cleared from the Nose-
piece without the need to handle the driver
blade.
3. Check the magazine; inspect and clear the
magazine of jams, this can include:
a. Residual collation material build-up.
b. Foreign matter preventing normal opera-
tion.
4. Check the Nosepiece.
Using a thin rod (approx 1/4” or 6mm) push
out any nails, nail fragments, collation ma-
terial, or foreign material inhibiting normal
operation.
5. Reassemble the tool with the nosepiece and
corresponding magazine without fasteners,
then insert the battery pack and turn ON the
nailer.
6. On HMI press the Reset Button for 3 sec to
enter the reset mode.
To retract the driver blade back to its correct
position and allow the motor to operate:
If using the Collated Magazine, pull the fol-
lower back before pressing the Nosepiece
against a wood block or similar and pull the
trigger.
If using Single Shot Magazine, press the
Nosepiece against a wood block or similar
and pull the trigger.
7. If other abnormal conditions are encoun-
tered during the mechanical reset of the
driver blade, then the status indicator will
display the appropriate status light color.

mal status, follow the “Daily Inspection and
Testing” to ensure normal operation of the
nailer.
