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,

“live” electrical wires may be encountered, try to
ascertain whether there is a danger of shock.
Hearing protection. Wear ear protection when
using the tool for extended periods. Prolonged
exposure to high intensity noise can cause
hearing loss.
Safety glasses To prevent eye injuries, the tool
operator and all persons in the work area must
wear approved safety glasses conforming to ANSI
Z87.1 specications with permanently attached,
rigid side shields.
Use clean, dry, regulated, compressed air at 70
to 120 psi.
Do not connect tool to pressure which
potentially exceeds 200 psi.
Air hose. Only use hose that is rated for a
minimum working pressure of 150 psi or 150%
of the maximum system pressure, whichever is
greater.
Never use oxygen, carbon dioxide, combustible
gases or any other bottled gas as a power
source for this tool. Explosion and serious
personal injury could result.
Couplings. Connect tool to the air supply hose
with 1/4” NPT couplings that remove all pressure
from the tool when the coupling is disconnnected.
Be aware of air hoses and their connections.
Don’t trip over hoses. Make sure all connections
are tight.
Disconnect tool from air supply hose before
return springs may be improperly mounted.
When servicing tool, use only identical

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 019-4274 is a light duty, coil fed, pneumatic nailer, using
compressed air as a power source. It is designed to install 2”– 3-9/16”, 11-1/2 ga.
to 10-1/4 ga. spiral, ring or smooth wire-collated nails with a collation angle of 15
degrees. 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.

USING THE TOOL
Complete all steps as indicated in LOADING FASTENERS before use.
This tool can be red in two different ways:
1. Sequential Fire:
= Turn the trigger mode selector (D, g.1) so the tail of selector is up.(g.6)
= Put the contact tip (A, g.1) of the tool on the working surface
= Lightly push the tool toward the working surface until the safety bracket is
depressed
= Press the trigger (E, g.1) to drive the fasteners. This “trigger re” method
provides the most accurate fastener placement.
2. Bump Fire:
= Turn the trigger mode selector (D, g.1) so the tail
of selector is down.(g.6)
= Hold the contact tip (A, g.1) off the surface
= Press the trigger
= Keeping the trigger pressed, push the contact tip
(A, g.1) of the safety bracket against the work-
ing surface. Once the bracket is pushed back
enough, the nail will re.
= Original factory setting is single sequential re mode.
= READ and UNDERSTAND this operating manual before changing trigger
mode. Improper use may result in serious injury.
= Manufacturer assumes no responsibility for any injuries and loss caused by
improper use of the tool.
8. Draw the nails out and position the second nail on to the feed hook (M, g.4).
9. Close cover-plate and latch (L, g.3).
10. Rotate the directional exhaust deector (C, g.1), so that the exhaust air blast
will be directed away from the operator.
11. 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.
12. The tool is ready to operate.
IMPORTANT
!

10
CLEARING A JAMMED FASTENER
CAUTION
!
Disconnect the tool from the air supply.
1. Open latch
2. Rotate lower magazine
3. Remove the nails from the magzine.
4. Use a slender; soft steel rod to drive the drive blade to its uppermost position.
5. Use a pair of needle nose pliers to remove the jammed fastener.
FASTENER DEPTH
Driving depth can be adjusted by rotating the depth adjustment knob (B, g.1).
=Test re a fastener into a scrap work piece and check
depth.
=If the nail is driven too deep, rotate the knob (B, g.7)
clockwise (when tool is upside-down) to move the
safety bracket downward.
=If a greater depth is desired, rotate the knob counter
clockwise to adjust the safety bracket upward.
=Test re another fastener in a scrap work piece and
check the depth.
=REPEAT AS NECESSARY UNTIL DESIRED DEPTH
IS ACHIEVED. The amount of air pressure required will
vary depending on the setting.
=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.
CAUTION
!
= Disconnect tool from air supply before loading fasteners, performing
maintenance, clearing a jammed fastener, leaving working area, moving tool to
another location or handing the tool to another person.
= Clean and inspect tool daily. Carefully check for proper operation of trigger and
safety mechanism.

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 2 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
parts. The exposed portion of the small piston rod and feed hook must be kept
clean.
= Inspect trigger and safety mechanism daily to assure system is complete and
functional.
= Keep all screws tight. Loose screws can cause personal injury or damage to
the tool. Check if there are worn and damaged parts. If any, please replace
immediately.
CAUTION
!
=Keep the tool pointed away from yourself and others at all times.
