Always DISCONNECT THE AIR SUPPLY before making any adjustments, repairing, clearing jams or
when the stapler is not in use. Do not use on scaffolding or ladders and disconnect stapler from air
supply when transporting between installation areas.
Never attach the female end of a quick disconnect to the stapler. This will trap air inside the stapler and
permit it to be discharged. Only the unrestricted male connection should be attached to the stapler.
Stapler requires an air source that can continuously deliver 70 to 120 psi at 3-1/2 cubic feet of air per
minute for operation. Normal air pressure should not exceed 120 psi or damage to the stapler and
seals may occur. Excess air pressure can cause the stapler to explode. Do not continue to use a tool
that leaks air or does not function properly. Notify your nearest Powernail representative if your tool
continues to experience functional problems.
To prevent fi re or explosion, use only regulated compressed air—do not use bottled gases of any kind
(no oxygen or combustible gasses) to power this stapler. Stapler is intended for use installing wood
fl ooring and is not to be used for purposes not specifi ed in the operations manual.
Do not use any staples other than Powernail® PowerStaples which are 18 gauge staples specifi cally
designed for use in any 18 gauge PowerStapler. PowerStaples are available in lengths of 7/8”, 1”,
1-1/8”, 1-1/4”, 1-1/2”. Contact your Powernail Dealer for the correct PowerStaples for the Model 1845F.
Use only Powernail replacement parts in the repair or maintenance of this stapler. Parts or repair
services are available from the manufacturer or from agents authorized by the manufacturer. Repairs
should be carried out only by trained service personel in the fi eld of fastener driving tools who will
observe proper safety controls while performing maintenance. Service personel should be qualifi ed to
assess the safe working condition of fastener driving tools.
Always make sure stapler is empty of staples before connecting air hose, so as to prevent any
accidental discharge from occurring. ONLY CONNECT AIR TO AN UNLOADED STAPLER.
Do not depress the trigger when loading. If the fasteners are jammed, disconnect the tool from the air
supply before you remove the jammed staples.
Never place any part of the body in the discharge path of the Stapler when air is connected to the
stapler. Never point the tool at yourself or others, even if the tool is not loaded. For safety,
keep out of reach of children. Never leave the stapler unattended while it is connected to an
air supply. Never disable, clamp or tape the safety trigger in an activated position.
Do not fi re into hard materials or attempt to use on hard or brittle material such as concrete,
steel or tile. Before using this tool, carefully check that all parts are working correctly. Do not use the
tool if it is not operating correctly, check for causes and adjust as necessary for proper operation. When
not in use, the tool should be cleaned, fully assembled and then stored in a dry location. This will extend
the life of the tool and reduce any oxidation.
When operating this stapler, the operator and others in the work area should ALWAYS
wear approved SAFETY GLASSES, with front and side eye protection. Eye protection
will help guard against fl ying nails and debris, which could cause severe eye injury.
EAR PROTECTION should be used to prevent hearing damage when there are high
noise levels in the work area. ALWAYS use ear plugs with a noise reduction rated at 29
db or higher at a construction site.
Do not operate this tool if it does not contain a legible WARNING LABEL.

The Model 1845F fastens down fl ooring from
3/8” to 5/8” using the Powernail FLEX adjustable
foot assembly that can be adjusted to fi t different
fl ooring profi les.
To use the Model 1845F, properly position the tool
on the fl ooring plank (See picture below). Pull up
and hold the black safety trigger to activate the
orange fi ring trigger. The stapler will drive and set
the nail at the correct angle.
Note: Modifying or altering the stapler in anyway
can potentially cause injury and may void the
warranty.
The unique body design allows for different grip
angles and has an adjustable exhaust port to
redirect stapler exhaust.

Use the photos on the right for reference:
1.) First loosen the tool’s FLEX foot by turning the lever
from right to left/counter clockwise. (See image 1.a)
a.) The FLEX foot should now freely slide up-and-down
the magazine.
2.) Using a sample of your fl ooring, slide the FLEX foot
back on the channel and set the nose of the stapler
securely into the nail pocket (see image 1.b). Important:
Orient the board as it is intended to be installed, with the
fl oor board’s surface facing up.
3.) While keeping the nose of the stapler/nailer in the
nail pocket (resting on top of the tongue and against the
shoulder) slide the FLEX foot forward until it lies fl at on
the fl ooring surface. (see image 1.c)
4.) Now turn the FLEX foot’s adjustment lever from left
to right (clockwise) to tighten the foot. (see image 1.d)
5.) Always test fi re into a test piece of fl ooring to ensure
the nail is setting correctly.
If your FLEX foot is not tight enough:
1.) If your tool’s foot is not tight enough or if the FLEX
foot is not maintaining its “set” position, you may adjust
its tightness by pulling OUT on the lever (see image 1.e)
and turning it from right to left (see image 1.f) . Release
the lever (make sure that it reseats) and turn from left
to right (see image 1.g). This is a form of ratcheting
mechanism and does not require any tools to loosen or
tighten.
a.) ***If your Flex Foot needs to be loosened, reverse
the process listed above.

LOADING STAPLES
1.) Pull the Staple Pusher to the
back of the Channel until it locks
into place over the Pusher-Lock
button.
2.) Lay the stick of staples
into the fi xed channel
Release the
Staple Pusher
Your air tool is fully assembled when you
receive it. Before using it, attach the air
line and desired air system accessories.
Be sure the air hose is depressurized
when installing or removing adapters to
the air line. To prevent misfi re, do not
connect air to a loaded stapler.
1.) An automatic airline oiler is
recommended but oil may be added
manually before every operation or after
about 8 hours of continuous use.
2.) Place two (2) drops of air-tool oil in the
air plug as shown (Figure 2). If you are
using an automatic in-line oiler, check and
add oil if necessary.
3.) Turn your compressor on and set
the compressors pressure regulator to
the proper pressure. Normal operating
pressure should be adjusted between 70-
120 psi based on fastener and wood being
used.
4.) Connect the tool to the air supply
(Figure 3).

REGULAR MAINTENANCE
1. Frequent, but not excessive, lubrication is required for best performance. Oil added through the airline
connection will lubricate internal parts. An automatic airline oilier is recommended but oil may be added
manually before every operation or after about 8 hours of continuous use.
Only a few drops of oil at a time are necessary. Too much oil will collect inside the tool and be blown out
during the exhaust cycle. ONLY USE PNEUMATIC TOOL OIL. Do not use detergent oil or additives, as
these lubricants will cause accelerated wear to the seals in the tool.
2. Use a small amount of oil on all moving surfaces and pivots.
7
3. Dirt and water in the air supply are major causes of pneumatic tool wear. Use a fi lter/oiler for better
performance and longer life. The fi lter must have adequate fl ow capacity for the specifi c application.
4. Keep tools clean for better and safer performance. Use nonfl ammable cleaning solutions only if
necessary. CAUTION: Soaking the tool may damage O-rings and other
tool parts.
