7.2.5 Checking and adjusting fastener driving
depth 6 7
NOTE
Fastener driving depth can be adjusted by turning the
power regulation wheel on the tool (setting 1 = minimum;
setting 4 = maximum).
1. Use the test gauge to check nail stand-off.
2. If a fastener is not driven deeply enough, driving
power must be increased. Adjust the power regula-
tion wheel to the next higher setting. If a fastener is
driven too deeply, driving power must be reduced.
Adjust the power regulation wheel to the next lower
setting.
3. Drive a fastener.
4. Use the test gauge to check nail stand-off.
5. If the fastener is still not driven deeply enough or,
respectively, is driven too deeply, steps 2 to 4 must
be repeated until the correct depth is achieved. If
necessary, use a cartridge with a higher or lower
power rating.
