Observe work area conditions2. . Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.
Keep children away3. . Children must never be allowed in the work area. Do not let them
handle machines, tools, extension cords, or air hoses.
Store idle equipment4. . When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
Use the right tool for the job5. . Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool. There are certain applications for which this tool was
designed. It will do the job better and more safely at the rate for which it was intended. Do
not modify this tool and do not use this tool for a purpose for which it was not intended.
Dress properly6. . Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.

Do not overreach8. . Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.
Maintain tools with care9. . 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, have them repaired by a qualified technician. The handles
must be kept clean, dry, and free from oil and grease at all times.
Disconnect air supply10. . Disconnect air hose when not in use.
Remove adjusting keys and wrenches11. . Check that keys and adjusting wrenches are
removed from the tool or machine work surface before plugging it in.
Avoid unintentional starting12. . Do not carry any tool while holding the trigger, whether
it is plugged in or not.
Stay alert13. . Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
Check for damaged parts14. . Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualified technician. Do

if taking prescription medicine to determine if your judgement or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the tool.
Use proper size and type extension cord18. . If an extension cord is required for the air
compressor, it must be of the proper size and type to supply the correct current to the
tool without heating up. Otherwise, the extension cord could melt and catch fire, or cause
electrical damage to the tool. Check your compressor’s manual for the appropriate size
cord.
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.
Maintenance19. . For your safety, maintenance should be performed regularly by a qualified
technician.
Compressed air only20. . Never use combustible gases as a power source.
Warning: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It must be
understood by the operator that common sense and caution are factors which cannot
be built into this product, but must be supplied by the operator.

Loading the Tool
Warning! Disconnect the Stapler from the air compressor whenever loading or servicing. After
disconnecting the Stapler from the air compressor, there could still be enough air pressure to
fire the Stapler. After the air compressor hose is disconnected, always fire the Stapler into a
piece of scrap to make sure all of the air is expended.
1. Grip the Sleeve (78) and pull out the Magazine Cover (72).
Caution: The Magazine Cover (72) may snap closed with force, sometimes without
warning.
2.
Cleats
FIGURE 1
Install fasteners:
Cleats – Place the Cleats into the larger slot in the magazine so that the top of the cleat
rests on the rail in the center of the magazine. See Figure 1, above.
Staples – Place the staples over the center rail of the magazine.
Note: Only use the fastener types and sizes listed on the Specifications Chart on page 2.
3. While holding the Sleeve (78) securely, slide the Magazine Cover (72) closed.

Operation
1. Connect the Floor Stapler to the air hose and turn on the air compressor.
Note: Before using on a floor, test the unit on a scrap piece of wood. Adjust the driving depth
by providing more or less air pressure. Never exceed 125 PSI.
Warning! Keep your feet clear of the Stapler. Refer to Figure 2.
2. Hold the Handle (44) securely with one hand and grip the Hammer with the other
hand.

Fasteners exit the Stapler from the bottom in the
direction indicated above.
Hammer
Face (1)

(This helps prevent
unintentional firing.)
FIGURE 2
Make sure the Base Plate (52) is over the Fastener target position. Press down hard
so that the Base Plate (52) is firmly contacting the floor. Then squeeze the Trigger (33)
and strike the Hammer Face (1) with the Hammer to drive out a Fastener. Lift the tool
off of the floor. See Figure 3.
4. Repeat the process until you are finished. Then, disconnect the Floor Stapler from the
air source.
Warning! After disconnecting the Stapler from the air compressor, there could still be enough
air pressure to fire the Stapler. After the air compressor hose is disconnected, always
fire the Stapler into a piece of scrap to make sure all of the air is expended.

Anytime any maintenance or repairs are done (including clearing jams), FIRST:
1. Disconnect the Stapler from the air hose.
2. Empty Magazine (59, 69) completely.
3. Attempt to fire the Stapler into a piece of scrap wood to ensure that it is disconnected
and is incapable of firing any Fasteners.
4. Always leave Magazine Cover (72) closed during maintenance. The Magazine
Cover is spring-loaded and may cause parts or a Fastener to fly out of the Stapler
if it suddenly snaps closed.
Clearing Jams
1. Disconnect tool from air hose, empty Magazine (59, 69) of Fasteners, release any built-
up air pressure, and keep the magazine closed, as explained above.
2. While doing this step and the next, hold the Stapler pointed away from you and any other
people or fragile objects. Remove all three Screws (49) and Washers (4) on the Driver
Cover (48). See Figure 4.

Driver
Blade
Carefully lift the Driver Cover (48) off and remove the jammed Fastener. Pliers may be
necessary to remove a stuck Fastener.
4. Inspect the Driver on the end of the Piston Assembly (26) for bends or breakage. If it is
damaged, do not use the tool until it is repaired by a qualified technician. See Figure
5.
5. Lightly oil the driver and replace the Driver Cover (48). Make sure that the Driver Cover
(48) fits in place flush and that the Driver does not get pinched by it. Replace and se-
curely tighten all of the Screws (49) and Washers (4).
6. Reload the Stapler and reconnect it to the air hose.
7. Press the tip of the Stapler against an appropriate piece of scrap wood.
8. Test fire the Stapler several times, checking for proper operation.
