below may result in serious personal injury.
SAVE THESE INSTRUCTIONS
WARNING
!
Work Area
Keep work area clean and well lit. Cluttered
benches and dark areas invite accidents.
Keep by-standers, children, and visitors away
while using your tool. All children should be kept
away from the work area. Don’t let them handle
machines, tools or extension cords. Visitors can
be a distraction and are difcult to protect from
injury. Distractions can cause you to lose control.
Personal Safety
Stay alert. Watch what you are doing & use
common sense. Keep hands and body away from
the path of any potential red fastener. Do not
operate any tool when you are tired, under the
inuence of drugs, alcohol, or medication. A
moment of inattention while operating this tool
may result in serious injury.
Dress properly. Do not wear loose clothing
or jewelry; they can be caught in moving parts.
Protective, non-electrically conductive gloves
and non-skid footwear are recommended when
working. Wear protective hair covering to contain
long hair and keep it from harm. Keep hands dry,
clean and free from oil and grease.
Safety glasses To prevent eye injuries, the tool
operator and all persons in the work area must
wear ANSI Z87.1 approved safety glasses with
permanently attached, rigid side shields.
Hearing protection. Wear ear protection to
safeguard against possible hearing loss.
Guard against electric shock. Prevent body
contact with grounded surfaces: pipes, radiators,
ranges, and refrigerator enclosures. Before
driving fasteners into walls, oors, or wherever
“live” electrical wires may be encountered, try to
ascertain whether there is a danger of shock.
Do not overreach. Keep proper footing and
balance at all times. Do not reach over or across
machines which are running.
Employers must enforce compliance with the

SAFETY RULES FOR AIR NAILERS
doing any disassembly, maintenance, loading
fasteners, clearing a jammed fastener, leaving
the work area, moving the tool to another
location, or handing the tool to another person.
Never use a tool that is leaking air, has missing
or damaged parts, or requires repair. Before
each use, make sure all screws and caps are
securely tightened.
Check for damaged parts. Never use a tool if
safety, trigger, or spring are inoperable, missing or
damaged. Do not alter or remove safety, trigger,
or springs. Make daily inspections for the free
movement of trigger and safety mechanism.
Replacement parts. When servicing, use
only identical replacement parts and fasteners
recommended by us.
Be sure the tool is disconnected from the air
supply before loading the fasteners. Take
care on re-connection: fasteners may be red
accidentally during connection. The fastener
driving mechanism may cycle when the tool is
connected to the air supply.
Assume the tool contains fasteners at all times.
Always keep it pointed away from yourself and
others. No horseplay. Respect the tool as having
lethal potential.
Do not load fasteners with trigger or safety
depressed. The tool may unintentionally re a
fastener.
Do not depress the trigger unless the nosepiece
is directed at the worksurface or when not
driving fasteners. Never carry tool with nger on
or touching the trigger mechanism: tool may re
an unwanted fastener.

5
The warnings, cautions, and instructions detailed in this manual cannot cover all
possible conditions and situations that occur. It must be understood by the operator
that COMMON SENSE AND CAUTION ARE FACTORS that cannot be built into
this product, but MUST BE SUPPLIED BY THE OPERATOR.
Fire fasteners into work surface only and never
into materials too hard to penetrate
Grip tool rmly to maintain control while
allowing the tool to recoil away from the work
surface as the fastener is driven. If the safety is
allowed to recontact the work surface before the
trigger is released, an unwanted fastener will be
red.
Do not drive fasteners on top of other
fasteners, or with the tool at too steep an angle:
the fasteners can ricochet causing personal injury.
Do not drive fasteners too close to the edge
of the workpiece. The workpiece is likely to
split, allowing the fasteners to y free or ricochet
causing personal injury.

OPERATION AND USE INSTRUCTIONS
WARNING
!
BE SURE THAT YOU READ, UNDERSTAND
AND FOLLOW THE SAFETY RULES THAT ACCOMPANY THIS
MANUAL. THIS WILL ALLOW FOR BEST USE AND MAXIMUM
USER SATISFACTION.
The Vulcan Model 039-8438 is a light duty, coil fed, pneumatic nailer, using
compressed air as a power source. It is designed to install 7/8”– 1-3/4”, 11 ga.
(0.120”) at, full round-head roong coil nails in 120 nail, 15 degree wire-collated
rolls. The tool is made with a magnesium alloy body and cylinder cap to provide
light weight while maintaining high strength and rigidity.
POWER SOURCE
This tool is designed to operate on clean, dry, compressed air at regulated
pressures between 70 - 120 psi (max. 120 psi). The preferred system would include
a lter, a pressure regulator, and an automatic oiler located as close to the tool as
possible. (Within 15 ft. is ideal). All compressed air contains moisture and other
contaminates that are detrimental to internal components of the tool. An airline lter
will remove most of these contaminates and signicantly prolong the life of the tool.
If an in-line oiler is not available: place 5 or 6 drops of oil into the tool’s air inlet at
the beginning of each workday.

WARNING
!
l All line components (hoses, connectors, lters, regulators, etc.) must meet
150% of the maximum system pressure. Please try to use a hose of ID 3/8”
connecting nailer with compressor.
l Do not connect this tool to a system with maximum potential pressure greater
than 180 psi.
l Disconnect your air line from your nailer using the quick connect on the air
hose. Do not unscrew the air inlet from the nailer with your air hose connected.
l Disconnect the tool from the air supply before loading fasteners, performing
maintenance, clearing a jammed fastener, leaving the work area, moving the
tool to another location, or handing it to another person.

3. The adjuster plate can be moved up and down
when twisting the adjuster nut (B, g. 4).
According to the length of nail, the adjuster
plate should be adjusted correctly to the posi-
tion indicated inside the lower nail housing.
4. Place a coil of nails over the lower nail housing. Uncoil
enough nails to reach the feed hook and place the
second nail between the teeth on the feed hook
(Fig. 4A).
5. Close the magazine cover. Close and latch the feeder
cover.
6. Adjust the directional exhaust de ector so that the
exhaust air will be directed
away from the operator. Grasp the de ector and rotate it to the desired
position.
7. Adjust the shingle guide by loosening the retaining screw and sliding
the shingle guide to the desired position. Tighten the retaining screw
rmly. (The shingle guide can be used as an aid in positioning the
shingle to be nailed at a specic distance from the front edge of the
previous row of shingles.)

USING THE TOOL
This tool can be red in two different ways:
1. Position the nose of the tool onto the work surface, push forward on the tool
to depress the safety, and squeeze the trigger to re a nail. This “sequential”
method provides the most accurate fastener placement.
2. Squeeze and hold the trigger while pushing the nose of the tool against the
work surface. The tool will re a nail every time the safety is depressed. This
“bump re” method allows very fast, repetitive fastener placement.
CAUTION
!
= Remove nger from the trigger when not driving fasteners.
= Never carry tool with nger on trigger: tool will re a fastener if the safety is
bumped.
= Keep tool pointed in a safe direction at all times.
= Never attempt to drive nails into materials too hard to penetrate, or at too
steep an angle, or too near the edge of the workpiece. The fastener can
ricochet causing personal injury.
= Disconnect tool from air supply before doing any disassembly, maintenance,
clearing a jammmed fastener, leaving the work area, moving the tool to another
location, or handing the tool to another person.
= Clean and inspect the tool daily. Carefully check for proper operation of trigger
and safety mechanism. Do not use the tool unless both the trigger and
the safety mechanism are functional, or if the tool is leaking air or needs any
other repair.
The depth to which a nail is driven is controlled by the depth
adjustment knob (g.6), reachable through the window in the front
of the clear plastic guard. The depth of drive is factory adjusted to
maximum.
Test re a nail into a sample of the material you will be working
on and check depth. If a change is desired, rotate the adjustment
knob clockwise (upward)
to increase the depth, counterclockwise (downward) to decrease it.
Test re another nail and check depth again. Adjust as necessary.

8. Re-connect the tool to the air supply, being careful to aim the nosepiece
in a safe direction, and careful to avoid touching the trigger or the safety
mechanism. This is to prevent harm from fasteners accidentally discharging
should the fastener driving mechanism cycle when the tool is connected to the
air supply.
9. The tool is ready to operate.

MAINTENANCE
CAUTION
!
Disconnect the tool from the air supply before cleaning and
inspecting the tool. Correct all problems before operating.
CLEAN AND INSPECT DAILY
= Add pneumatic tool oil into the oiler regularly to assure that all moving.
Frequent, but not excessive lubrication is required for the best performance.
Oil added through the air line connection will lubricate the inside parts. An
automatic oiler is recommended, but 5 to 6 drops of oil may be added manually
into the tool’s air intake at the male quick-connect tting (F, g.1) at the
beginning of each workday and after about every hour of continuous use. Only
a few drops at a time are necessary. More than this will pool inside the tool
and be expelled from the tool’s exhaust during ring. USE ONLY PNEUMATIC
TOOL OIL. Do not use detergent oil or oil with other additives, as these can
cause accelerated wear on the seals.
= Check the lter of the compressor weekly. Open drain cock to drain all water
and contaminants out of the air tank.
= Wipe the tool clean.
= Blow the tool clean using high compressed air, and then use non-ammable
cleaning solutions to wipe exterior of tool if necessary.
= Do not soak tool in cleaning solutions. Such solutions can damage internal
CLEARING A JAMMED FASTENER
CAUTION
!
