source before making any
adjustments, changing the
accessories, or storing the tool.
11) Do not load fasteners with
the air line connected, or with
trigger or Work Contact Element
(WCE) depressed.
12) Always fit tool with a fitting or
hose coupling on, or near, the

SETTING
Your air tool is fully assembled
when you receive it. Before
using it, attach the air line and
desired air system accessories.
See Figure 1 for the
recommended accessories and
connection order. Be sure the
air hose is depressurized when
installing or removing adapters
to the air line.
CONNECTING THE TOOL TO
AN AIR SUPPLY
1. Determine if the tool needs
oil and, if necessary, place two
drops of oil in the air plug as
shown in figure 2.

3
If you are using an automatic in-
line oiler, check and add oil if
necessary
2. Turn the compressor on and
set the regulator to the proper
pressure for the size and type of
fastener being used.
3. Connect the tool to the air
supply (see Figure 1 for
recommendations).
LOADING THE FASTENERS
1. Depress the lock to release
the movable magazine and pull
the magazine out fully as shown
in Figure 3.
2. Place a full clip of the
specified type and size of
fasteners on the fixed magazine,
up to 100 fasteners may be
loaded in the magazine.
3. Push the movable magazine
assembly forward until it locks.
OPERATING THE TOOL
Test the driving depth in a
sample piece of wood before
using. If the fasteners are being
driven too far or not far enough,
adjust the regulator to provide
less air pressure or more air
pressure.
1. Connect the tool to the air
supply. Make sure the air
pressure is in correct range
denoted in the specifications.
2. Load the fasteners.
3. Hold the body and press the
drive guide to the work surface.
Be sure the tool is straight and
the gently depress the trigger to
drive the fastener.
4. Lift the tool off the work
surface.
5. The tool has two driving
modes:
!Put the nose on the work
surface. Lightly push the tool
toward the working surface until
the safe bracket is depressed.
Depress the trigger to drive the
fastener.
!Depress the trigger, then
repeatedly impact the safe
bracket. The tool can repeatedly
drive the fasteners. The tool will
drive one fastener at a time.
REGULAR MAINTENANCE
1. Frequent, but not excessive,
lubrication is required for best
performance. Oil added through
the airline connection will
lubricate internal parts. An
automatic inline oiler is
recommended, but oil may be
added manually before every
operation or after about 1 hour
of continuous use. (see Figure
1) Only a few drops of oil at a
time are necessary. Too much
oil will use detergent oil or
additives, as these lubricants
will cause accelerated wear to
the seal in the tool.
2. Use a small amount of oil on
all moving surfaces and pivots.
3. Dirt and water in the air
supply are major causes of
pneumatic tool wear. Use a
filter/oiler for better performance
and longer life. The filter must
have adequate flow capacity for
the specific application. Consult
the manufacturer’s instructions
for proper maintenance of your
filter.
4. Keep tools clean for better
and safer performance. Use
nonflammable cleaning
solutions only if necessary.
(CAUTION: Such solutions may
damage O-Ring and other tool
parts) DO NOT SOAK.
