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

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

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.
SETUP & OPERATION
UNPACKING THE TOOL
Check and make sure one of each of the following are all included.
l Combination Nailer Stapler
l S3 hex key
l S4 hex key
l Small bottle of air tool oil
l Operating instructions
AIR SYSTEM
l The combination brad nailer / stapler is designed to operate on clean, dry, compressed
air, regulated at 60-100 psi. The preferred system would include a lter (E), a pressure
regulator (F) with a gauge (G), and an automatic oiler (H) located downstream from the
main air supply (I), as close to the tool (A) as possible (within 15 feet is ideal). Do not use
bottled air or gases. Please see gure below:
l All compressed air contains moisture and other contaminants that can harm the internal
components of the tool. An air line lter (E) will remove most of these and signicantly
prolong the life of the tool. Ensure the in-line oiler (H) has sufcient oil. If an in-line oiler is
not available, place 2 drops of oil into the tool’s air inlet at the beginning of each workday.
More than this will be expelled from the tool’s exhaust during ring.
l Air Fitting: The nailer (A) should be equipped with a 1/4” NPT male plug (B) to t a ‘quick
connector’ coupling (C). To prevent accidental cycling even though disconnected, the
tool must always be connected to the air supply in such a way that all air pressure in it is
released when the coupling is disconnected.

OPERATING THE TOOL
1. The depth to which a fastener is driven is determined by both the supplied air pressure
and the drive depth setting.
1a. Test re a fastener into a sample of the material you will be working on and check
depth.
1b. If a change is desired, adjust the drive depth thumbwheel below the trigger (part of
#29, the Safety bracket assembly; located on the Schematic Drawing between parts
#28 and #29). To increase the drive depth turn the thumbwheel to the left, to
decrease depth move it to the right.
1c. Test re another fastener and check depth again.
1d. Adjust as necessary.
1e. To make adjustments beyond the range of the drive depth adjustment thumbwheel,
adjust the regulator to supply air at a higher or lower pressure.
1f. Drive depth settings will vary between staples and brads of the same length.
CAUTION
!
l Keep tool pointed in a safe direction at all times.
l Never attempt to drive fasteners into materials too hard to penetrate, at too steep an
angle, or too near the edge of the workpiece. The fastener can ricochet causing personal
injury.
l Disconnect tool from air supply before loading fasteners, doing any disassembly,
maintenance, clearing a jammed fastener, leaving the work area, moving the tool to
another location, or handing the tool to another person.
l 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

MAINTENANCE
DAILY MAINTENANCE
CAUTION
!
l Disconnect tool from air supply before cleaning and inspection.
l Correct all problems before putting the tool back in service.
1. Wipe tool clean and inspect for wear or damage. Use non-amable cleaning solutions to
wipe exterior of tool only if necessary. Do Not Soak tool with cleaning solutions. Such
solutions can damage internal parts.
2. Inspect trigger and safety mechanism to assure system is complete and functional: no
loose or missing parts, no binding or sticking parts.
3. Keep all screws tight. Loose screws can cause personal injury or damage the tool.
4.
If the tool is used without an in-line oiler, place 2 drops of air tool oil into the
air inlet of the tool at the beginning of each workday and after about 1 hour of
continuous use. Frequent but not excessive lubrication is
required for best performance. Oil added through the airline
connection will lubricate all internal parts. Use only air tool oil.
Do not use oil with detergents or other additives. These can
cause damage through accelerated wear to the seals in the
tool.
5. Use a small amount of oil on all exterior moving parts and
pivots.
6. Dirt and water in the air supply are major causes of pneumatic
tool wear. See the section on SETUP: AIR SYSTEM for more
information.
7. Keep tools clean for better and safer performance. Use non-
ammable cleaning solutions sparingly and only if necessary.
Do not soak parts in the solutions.
