Adjusting Depth (Fig. E)

WARNING: To reduce risk of serious injury from accidental
actuation when attempting to adjust depth, ALWAYS:
- Disconnect air supply and engage trigger lock.
- Avoid contact with trigger during adjustments.
The depth that the fastener is driven can be adjusted using
the depth adjustment next to the trigger of the tool. The
depth of drive is factory adjusted to a nominal setting. Test
fire a fastener and check depth. If a change is desired:
1. To drive the nail shallower, rotate the depth adjustment
6
wheel to the right.
2. To drive a nail deeper, rotate the depth adjustment
wheel to the left.
The adjustment knob has detents as it is rotated. Test drive
another fastener and check depth. Repeat as necessary to
achieve desired results. The amount of air pressure
required will vary depending on the size of the fastener
and the material being fastened. Experiment with the air
pressure setting to determine the lowest setting that will
consistently perform the job at hand. Air pressure in excess
of that required can cause premature wear and/or damage
to the tool.
