Foreword:
This pneumatic nailer isdesigned for using on soft material or driving tacks/decorative nails
into wood. Itswell balanced,ergonomic and comfort non-slip cushioned grip ensure you a
satisfactory tackle and improve work efficiency. One offeaturesis to drive differentsizesof
loose nails. No more painfulhammering.
Suitable applications:
Leather upholstery, shoes, antique, trimming mattresses
Caution:
Staplers are only applying on wood. Not suitable for stapling or nailing into concrete,
masonry bricks or steel. Do not fire if staples are jammed, as this will cause damage to the
relevant parts.
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
WARNING
Indicatesan potentially hazardous situation which, if not avoided, will result in death or
serious injury.
NOTE
Alerts the operator to useful information.
SAFETY INSTRUCTIONS
DANGER
1.Read this manual and understand all safetyinstructionsbefore operation the tool. If you
have any questions, please contact our authorized representatives.
2. Onlythose fastenerslisted in the operating instructions may be used in the fastener driv-
ing tools.
3. Onlythe main energy and the lubricantslisted in the operating instructions may be used.
4. Fastener driving tools marked with an inverted equilateral triangle standing on one point
may onlybe used with an effective safetyyoke.
5. Fastener driving tools equipped with contact actuation or continuous contact actuation,
marked with the symbol" Do not use on scaffoldings,ladders", shall notbe used for spe-
cific application for example:
─when changing one driving location to another involves the use of scaffoldings, stairs,
ladders, or ladder alike constructions, e.g. roof laths,
─closing boxes or crates,
─fitting transportation safety systems e.g. on vehicles and wagons.
6. For the maintenance of fastener driving tools, only spare parts specified by the manufac-
turer or his authorized representative shall be used.
7. Repairs shall carried out by agents authorized by the manufacturer or by other specialis-
ts,having due regard to the information given in the operating instruction.
8. Standsfor mounting the fastener driving toolsto a support for example a work table shall
be designed and constructed by the stand manufacturer in such a waythat the fastener
driving toolcan be safelyfixed for the intended use,thus forexample avoiding damage,
distortion or displacement.
9. Fastener driving tools operated bycompressed air shall only be connected to compress-
ed air lines where the maximum allowable pressure cannotbe exceed by a factorof
more than 10%, which can for example be achieved bya pressure reduction valve
which includesa downstream safetyvalve.
10. When using fastener driving tools operated bycompressed air,particular attention must
be paid to avoid exceeding the maximum allowable pressure.
11. When using fastener driving toolsoperated by compressed air should onlybe operated
at the lowest pressure required for the workprocessat hand, in order to prevent unnece-
ssarilyhigh noise levels, increased wear and resulting failures.
12. Hazards caused by fire and explosion when using oxygen or combustible gasesfor ope-
rating compressed airoperated fastener driving tools.
13. Carry the fastenerdriving tool atworkpiece using onlythe handgrip,and never with the
trigger actuated. Never carrythe tool by the hose orpull the hose to move the tool.
14. Disconnectthe tool from air supply before cleaning jams,
servicing, adjusting, and during non-operation.
15. Wear eye protection.
16. Do not use a check valve or anyother fitting which allows
air to remain in the tool.
17. Do not place your hand or any part of your body in the
fastener discharge area of the tool when connecting or
disconnecting air supply.
18. Never point tool at yourself or at any other person.
AIR SUPPLY AND CONNECTION
NOTE
•Many airtool usersfind it convenient to use oilerto help provide oil
circulation through tool and increase the efficiencyand useful life
of the tool. Check oil level in the oiler daily.
•Many airtool user find itconvenient to use a filterto remove liquid
and impurities which can rust or wear internal parts of the tool. A
filter also increase the efficiency and usefulof the tool.The filter
must be checked on a dailybasis and if necessary drained.
•For better performance, install a 3/8" quick connector (1/4" NPT
threads) with an inside diameterof .315" on yourtool and a 3/8"
quick coupler on the air hose.
The following illustration shows the correct mode of connection to the air
supply system which will increase the efficiency and useful life of the tool.
LUBRICATION AND MAINTENANCE
NOTE
•Disconnect the air supplyfrom the toolbefore lubricating.
•Your tool requires lubrication before you use it for the first time.
•Wipe off excessive oil at the exhaust. Excessive oil will damage
O-ringsof tool. If in-line oiler is used, manual lubrication through
the air inlet is not required on a daily basis.
•Turn the tool so the inletis facing up and put one drop ofhigh
speed spindle oil, UNOCAL RX22, or 3-IN-1 oil into air inlet. Never
use detergent oil or additives. Operate the tool briefly after adding
oil.

LOADING THE TOOL
WARNING
•Do not place your hand orany part of your bodyin the
fastenerdischarge area of the tool when connecting or
disconnecting air supply.
WARNING
•Never point any operational fastener driving tool at
yourself or at any other person.
1. Disconnect air hose.
2. unscrew the screw and adjust the mouthpiece to
demended working position then screw tight the screw.
3. Place decorative upholstery nails into the template for
perfect alignment of the nail into the ZN-12M.
4. When you press the tool over the template the magnet
inside the nose will pick the nail and seat it properly for
straight and effortless driving of nails.
OPERATING THE TOOL
WARNING
Protect youreyes and ears. Wear z87.1 safety glasses with side
shields. Wearhearing protection.Employers and usersare
responsible for ensuring the user or anyone near the tool wear this
safety protection.
NOTE
Check and replace anydamaged or worn components on the tool.
The safety warning labelson the tool mustalso be replaced if they
are not legible.
1. Add a few dropsof UNOCAL RX22 or 3-in-1 oil into the air inlet.
(See Fig. 1)
2. Attach a high flow quick connect fitting to the tool. (See Fig. 2)
3. Empty the magazine.
4. Connectthe tool to an aircompressor using a 3/8" I.D hose.Make
sure the hose has a rated working pressure exceeding 200 PSI
(13.8bar) and a female quickcoupler. (See Fig. 3)
5. Regulate the air pressure to obtain 70 PSI (4.8 bar)at the tool.
(See Fig. 4)
6. Disconnect the air supply from the tool.
7. Load fastenersinto your tool following the instructions in this
manual. (See Fig. 5)
8. Reconnect the air supplyto the tool.
9. Test for proper fastener penetration by driving nails into a sample
piece ofwood. If the fasteners do not achieve the desired
penetration, adjust the air pressure to a highersetting until the
desired penetration isachieved. Do notexceed 110 PSI (7.6 bar)
at the tool. (See Fig. 6)
CLEARING A JAM FROM THE TOOL
WARNING
Disconnect the tool from aircompressor before adjusting, clearing
jams, servicing, relocating and during non-operation.
Fastener jammed in fastener discharge area:
•Disconnect tool from air hose.
•Grab jammed fastener with pliers and remove.
CLEANING THE TOOL
DANGER
Never use gasoline or otherflammable liquids to clean the tool. Va
pors in the tool will ignite by a spark and cause the tool to explode
and result in death or serious personal injury.
NOTE
Solvents used to clean the nose ofthe tool and contacr safety trip
mechanism may soften the tar on the shingles and cause the
buildup to be accelerated. Make sure to dry the tool thoroughly
aftercleaning and before operating the toolagain.
1. Disconnectthe air supply from the tool.
2. Remove tar buildup with kerosene #2 fuel oilor diesel fuel. Do
not allow solvent to getinto the cylinderor damage may occur.
Dry off the tool completelybefore use.
