is above 85°F (30°C) or below 50°F (10°C).
This Nailer is equipped with the push lever and does not
operate unless the push lever is depressed (upward

4 Remove finger from the trigger.
To continue nailing in a separate location, move the
nailer along the wood, repeating steps 1 - 4 as
required.
ADJUSTING THE NAILING DEPTH

sure that the Nailer is always held firmly against the
workpiece.
If nails are driven too deep or shallow into the workpiece,
adjust the nailing in the following order.
1 Remove the fuel cell and the battery from the Nailer.
2 Loosen the bolt with wrench.
3 If nails are driven too deep, move the push lever to
