Always use clean, dry, regulated compressed air at 4.8 to 7.5 bar (70 to 110 PSI).
Do not exceed the maximum and minimum pressures. Operating the tool at the
wrong pressure will cause excessive noise, fast wear, or misfiring.
It is recommended that a filter-regulator-lubricator be used and be located as
close to the tool as possible.
If a filter-regulator-lubricator is not installed, place up to 6 drops of compressor
oil into the air inlet plug before each use.
If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will
reduce the air pressure to the tool, which will cause a reduction in power,
eciency, and general performance.
For optimal performance, install a quick connector to the tool and a quick coupler
on the hose, if applicable
Verify that all the connections in the air supply system are sealed in order to
prevent air from leaking.

The Framing Nailer has two firing modes: Single-Sequential actuation for single
firing, or Contact / bump actuation for repetitive, fast firing of nails. You may switch
between these two modes simply by adjusting the Mode Selection Switch on the tool.
For single sequential actuation mode, the selector switch must be positioned toward
the back of the tool (toward the single nail icon on the tool. For repetitive firing, also
know as contact or bump mode, the mode selector switch must be positioned toward
the front of the tool (toward the multiple nail icon on the tool).
Note: Refer to the graphic imprinted
below the trigger and adjust the firing
depth accordingly.
FIRING MODES
For varying materials, the nail depth
can be tool- free adjusted with the
depth adjustment dial (Fig G)
•
Adjusting nail depth
fig G
Turn the depth adjustment dial (1) clockwise (with the discharge area of the tool
facing away from the operator) (fig H).
Increasing nail depth
fig H fig I
Turn the depth adjustment dial (1) counter- clockwise (with the discharge area of
the tool facing away from the operator) (fig I).
Note: If after adjustment the nail is not going deep enough, adjust the pressure of
the regulator on the compressor accordingly.
Ensure the switch is positioned either fully in single sequential or contact/bump
mode, otherwise, if switch is in-between the tool will not function properly.

The single sequential actuation mechanism is for use where precise fastener
placement is desired. The single sequential actuation mechanism may reduce the
possibility of bodily injury to you or others in the work area compared to the
contact/bump actuation mechanism. This is because it is less likely to drive an
unwanted nail if you keep the trigger pulled and accidentally bump the push lever
against yourself or others.
The single sequential actuation mechanism may also reduce the speed of operation
compared to the contact/bump actuation mechanism. The single sequential
actuation mechanism is recommended to inexperienced users.
SINGLE SEQUENTIAL ACTUATION MODE
1. Set switch on tool to single sequential actuation mode (fig. J).
2. Position the nose of the tool on the workpiece with your finger o the trigger.
3. Depress the push lever on the firing head of the tool firmly against the workpiece
until it is completely depressed.
4. Pull the trigger to drive a nail.
5. Remove finger from the trigger.
6. To continue nailing in a separate location, move the nailer along the wood,
repeating steps 2-5 as required
1. Set switch on tool to contact or bump mode (fig. J).
2. Press and hold the trigger while operating in this mode. Each time the firing head
contacts a workpiece, a nail is actuated (fired). Lift the nailer and locate it at the
site for the next nail. Move the nailer along the workpiece with a bouncing
motion. Each depression of the push lever on the firing head of the tool will drive
a nail. As soon as the desired number of nails have been driven, remove finger
from the trigger.
3. This process can be repeated until the trigger is released. Extreme care should
be taken because a nail will be driven when the firing head contacts any surface.
4. Since nails can be actuated without removing the finger from the trigger, this is a
less controlled mode, suitable for more experienced users.
* This mode is suitable when less precise nail placement is required. It allows the
user to work more quickly.
