H8230/H8231 15° Roofing Nailer -9 -
The nailer is designed to fire one nail at a
time, or one after another, using the safety
nose mechanism—this is known as "bump
fire."
To operate your nailer in single fire
mode:
1. Depress the safety nose mechanism
against the workpiece.
2. Pull the trigger, then release the trigger
after the nail is driven.
To operate your nailer in bump fire
mode:
1. Pull the trigger and hold it back.
2. Press the safety nose mechanism
against your workpiece to fire a nail.
You can continue holding the trigger
back and firing the nailer in this manner
without releasing the trigger.
Single/Bump Fire
Operation
The Model H8230/H8231 features a depth
adjustment knob for controlling nail pen-
etration depth (
Figures 8 & 9).
Adjusting Depth
Figure 8. H8230 depth adjustment knob.
The adjustment knob controls nail penetra-
tion by changing where the nose mecha-
nism stops when depressed. Moving the
nose mechanism out or extending it away
from the nailer decreases nail penetration
depth.
Determining the correct nail penetration
depth requires trial-and-error and may
change depending on the type of material
you are nailing.

Take care to lift the nailer from the
workpiece each time you fire a nail
when bump firing, or the nailer may
bounce acriss the workpiece and rap-
idly fire nails.
