8. Use eye and ear protection. AlwayswearANSI approved impactsafety goggles
and appropriate hearing protection. Wear a full face shield if you are producing
metal filings or wood chips. Wear an ANSI approved dust mask or respirator
whenworkingaround metal, wood, and chemical dusts and mists. Other people
in the work area must also wear ANSI approved impact safety goggles.
9. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and,if damaged,havethem repairedbyanauthorizedtechnician.Thehandle
must be kept clean, dry, and free from oil and grease at all times. Do not operate a tool
if any portion of the tool’s operating controls are inoperable, disconnected, altered or not
working properly.
10. Disconnect Air Hose and release any built-up air pressure. Neverservicethe Nailer,
clear jams, or disassemble with the air hose attached. Always release any built-up air
even after disconnecting hose. Disconnect the Nailer when not in use.
11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are
removed from the tool or machine work surface before attaching to an air source.
12. Avoid unintentional starting. Be sure the trigger is in the Off position when not in use
and before plugging in.Do not carry any tool with your finger on the trigger, whether it is

heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the tool.Check your air compressor’s manual for the appropriate size cord. It
isalso possiblethat the use of an extension cord may cause yourcircuitbreakerto trip or
your panel fuse to break. If this happens, either use the compressor without an exten-
sion cord or find a larger amperage circuit to use.
19. Maintenance. Themaintenanceoutlinedinthemaintenancesectionshould be performed
regularly. For your safety, this product should be serviced or repaired regularly only by a
qualified technician.
20. Compressed air only. Never use combustible gas as a power source.
21. Do not load nails with the trigger or safety depressed. Unintentional firing
may occur. Do not load nails when the air hose is connected to the tool. Always
assume that the tool contains fasteners.
22. Disconnect air supply before loading Nailer. Before reloading (or making any
adjustments to) the Nailer make sure that the compressed air is disconnected.
23. Fire fasteners into an appropriate work surface only. Donot attempt to fire fasteners
into surfaces too hard to penetrate. Do not drive fasteners on top of other fasteners, or
at too steep of an angle. Fasteners can ricochet causing personal injury. Never fire the
Nailer into the air, or point it toward yourself or another person. Always wear ANSI
approved safety goggles during use, maintenance, and reloading.
24. Do not fire fasteners too close to the edge of a workpiece. They may split the
workpiece and fly free, causing personal injury.
25. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When stapling or nailing these materials extra
care should be taken to avoid inhalation and minimize skin contact.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities, contain chemicals known [to the State of California] to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other masonry products
• Arsenic and chromium from chemically treated lumber
(California Health & Safety Code 25249.5, et seq. )
26. Stay within air pressure capacity.Never operate the Nailer above 95 PSI.
27. Hold tool away from head and body. Duringoperationthe Nailer maykickbackcausing
injury.
28. Transport Nailer safely. Always disconnect air supply when moving the tool in the
workplace. Carry the tool by the handle and avoid contact with the trigger.
29. Avoid working alone. If an accident happens, an assistant can bring help.
Note: Performance of the compressor (if powered by line voltage) may vary depending on
variations in local line voltage.Extension cord usage may also affect tool performance.

3. The Nailer should not fire if the nose is not depressed against the workpiece.
4. Check that the Trigger (37) and the Safety (42) or “nose” move freely, without sticking -
see the illustration at the bottom of this page.
5. Connect the air supply to the tool at the 1/4” NPT Air Plug (72) set at the recommended
55-95 PSI, and set not to go over the maximum 95 PSI.
6. Test the tool by depressing the Safety (42) against the workpiece without pulling the
Trigger (37). The tool must not cycle (fire). If it cycles (fires), stop immediately and
have it repaired by a qualified service technician.
7. Hold the tool away or off of the workpiece. The Safety (42) of the tool should return to its
original position. Squeeze theTrigger (37). The tool should not cycle (fire). If it cycles
(fires), stop immediately and have it repaired by a qualified service technician.
8. Depress the Safety (42) against the workpiece and squeeze the Trigger (37). The tool
must cycle (fire) once only. Release the trigger and squeeze it again. The tool must
cycle (fire) once only. With theTrigger held, carefully lift the nailer and press it against
the workpiece again. The tool must not cycle (fire). If it fails to act in the manner
explained in bold, have it repaired by a qualified service technician.

Operation (continued)
Operating the Nailer
1. Attach the Nailer to the air supply at the 1/4” NPT Air Plug (72). Start your compressor
and check the pressure making sure it is set at the recommended 55-95 PSI and not to
go over the maximum 95 PSI.
2. To fire, place the nose of the Nailer on the workpiece. The Nailer should not fire if the
nose is not depressed. Once depressed, gently and briefly squeeze the Trigger (37)
once. Do not fire repeatedly. Nails could bounce off of one another, damaging the
work piece or causing PERSONAL INJURY.
Anytime any maintenance or repairs are done (including clearing jams),
FIRST:
1. Disconnect the Nailer from the air hose.
2. Empty the Outer Magazine (51) completely.
3. Attempt to fire the Nailer into a piece of scrap wood to ensure that it is disconnected
and is incapable of firing any brads.
1. Disconnect tool from air hose, empty the Outer
Magazine (51) of nails, release any built-up air
pressure, and leave the magazine open, as
explained above.
2. While doing this step and the next, hold the Nailer
pointed away from you and any other people or
fragile objects. Pull the Quick Release Lever (42)
forward to the position shown in Figure 1. Remove
the Driver Guide Cover (45).

Maintenance
1. Inspect the Air Nailer frequently and lubricate periodically with Pneumatic tool oil, then
wipe dry.
Do not use detergent oil or additives as these lubricants will cause accelerated wear to
the internal seals.
2. Inspecttheair supplyfilter,if present,beforeeach useand cleanor replaceas necessary.
Dirt and waterin the air supply are major causesof pneumatic tool wear.Use afilter/oiler
for better performance and longer tool life.The filter must have adequate flow capacity
for the specific application.
3. Store the unit in a clean and dry location.
4. Allmaintenance,service,or repairsnot listed in this manual are onlytobeattempted
by a qualified technician.
Anytime any maintenance or repairs are done, FIRST:
1. Disconnect the Nailer from the air hose.
2. Empty the Outer Magazine (51) completely.
3. Attempt to fire the Nailer into a piece of scrap wood to ensure that it is disconnected
and is incapable of firing any brads.
4. Always leave the Inner Magazine (58) open during maintenance. The Magazine
is spring-loaded and may cause parts or a nail to fly out of the Nailer.
5. Lightlyoil theDriver(18). ReplacetheDriverGuide
Cover (45) and latch the Quick Release Spring
(48) under both hooks, making sure it is securely
in place and the Quick Release Lever (42) is
pressed down - see Figure 3 .
