Foreword:
This pneumaticnailer is designed for using on soft material or driving tacks/decorative nails
into wood. Its well balanced, ergonomic and comfortnon-slip cushioned grip ensure you a
satisfactory tackle and improve work efficiency. One of features is to drive different sizes of
loose nails. No more painful hammering.
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
Alertsthe operator to useful information.
SAFETY INSTRUCTIONS
DANGER
1. Read thismanual and understand all safety instructionsbefore operation the tool.If you
have any questions, please contact our authorized representatives.
2. Onlythose fasteners listed in the operating instructions may be used in the fastenerdriv-
ing tools.
3. Onlythe main energy and the lubricants listed in the operating instructions maybe used.
4. Fastener driving tools marked with an inverted equilateral triangle standing on one point
may onlybe used with an effective safety yoke.
5. Fastener driving tools equipped with contact actuation or continuous contact actuation,
marked with the symbol " Do not use on scaffoldings, ladders", shallnot be used for spe-
cificapplication for example:
─when changing one driving location to anotherinvolves the use ofscaffoldings, 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 tools to a support for example a work table shall
be designed and constructed by the stand manufacturer in such a way that the fastener
driving tool can be safely fixed for the intended use, thus for example avoiding damage,
distortion or displacement.
9. Fastener driving tools operated by compressed air shall only be connected to compress-
ed air lines where the maximum allowable pressure cannotbe exceed by a factor of
more than 10%, which can for example be achieved by a pressure reduction valve
which includes a 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 tools operated bycompressed air should only be operated
at the lowest pressure required for the work processat hand, in order to prevent unnece-
ssarily high noise levels, increased wear and resulting failures.
12. Hazards caused byfire and explosion when using oxygen or combustible gases for ope-
rating compressed air operated fastener driving tools.
13. Carrythe fastener driving tool at workpiece using only the handgrip, and never with the
triggeractuated.Never carry the toolby the hose or pull the hose to move the tool.
14. Disconnect the tool from airsupply 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 bodyin the
fastener discharge area of the tool when connecting or
disconnecting air supply.
18. Never point tool at yourself or at anyother person.
AIR SUPPLY AND CONNECTION
NOTE
•Many airtool usersfind it convenient to use oiler to help provide oil
circulation through tool and increase the efficiency and usefullife
of the tool. Check oil level in the oiler daily.
•Many airtool user find it convenient to use a filter to remove liquid
and impurities which can rust or wear internal parts of the tool. A
filter also increase the efficiency and useful of the tool. The filter
must be checked on a daily basisand if necessary drained.
•For better performance, install a 3/8" quick connector (1/4" NPT
threads) with an inside diameter of.315" on your tooland 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 airsupply from the tool before 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 toolso the inlet is facing up and put one drop of high
speed spindle oil,UNOCAL RX22, or 3-IN-1 oil into airinlet. Never
use detergent oil or additives. Operate the tool briefly after adding
oil.

LOADING THE TOOL
WARNING
•Do not place your hand or any part of your bodyin the
fastener discharge 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. Place decorative upholsterynails into the template for
perfect alignment of the nail into the ZN-12M.
3. When you press the toolover 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 your eyesand ears. Wearz87.1 safety glasses with side
shields. Wear hearing protection. Employers and users are
responsible for ensuring the user or anyone near the tool wear this
safety protection.
NOTE
Check and replace any damaged orworn components on the tool.
The safety warning labels on the tool must also 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 air compressor using a 3/8" I.D hose. Make
sure the hose has a rated working pressure exceeding 200 PSI
(13.8bar) and a female quick coupler. (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 supplyfrom the tool.
7. Load fasteners into your toolfollowing the instructions in this
manual. (See Fig. 5)
8. Reconnect the air supply to the tool.
9. Test for proper fastener penetration by driving nails into a sample
piece ofwood. If the fastenersdo not achieve the desired
penetration, adjustthe air pressure to a higher setting until the
desired penetration is achieved. Do not exceed 110 PSI(7.6 bar)
at the tool. (See Fig. 6)
10. Measure nail head height first.Loose the screw and adjustthe
mouthpiece to the proper position that doesn’t hurt nail head
surface, screw tight the screw. (See Fig. 7 )
CLEARING A JAM FROM THE TOOL
WARNING
Disconnect the tool from air compressor 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 other flammable 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 of the tool and contacr safety trip
mechanism may soften the tar on the shingles and cause the
buildup to be accelerated. Make sure to drythe tool thoroughly
after cleaning and before operating the tool again.
1. Disconnect the air supplyfrom the tool.
2. Remove tar buildup with kerosene #2 fueloil or diesel fuel. Do
not allow solvent to get into the cylinder or damage may occur.
Dry off the tool completely before use.
