Routine Maintenance
What’s in the Box?
Frequent, but not excessive, lubrication is required for best performance. Oil added through the
airline connection will lubricate internal parts. An automatic airline oiler is recommended but oil
may be added manually before every operation or after about I hour of continuous use. Only a
few drops of oil at a time are necessary. Too much oil will collect inside the tool and will be blown
out during the exhaust cycle. ONLY USE PNEUMATIC TOOL OIL. Do not use detergent oil or
additives, as these lubricants win cause accelerated wear to the seals in the tool.
Use a small amount of ordinary light machine oil on all moving surface and pivots.
Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/oiler for
better performance and longer life. The filter must have adequate flow capacity for the specific
application. Consult the manufacturer's instructions for proper maintenance of your filter.
Keep tools clean for better and safer performance. Use nonflammable cleaning solutions only if
necessary (CAUTION: Such solutions may damage O-rings and other tool parts) - DO NOT
SOAK.

General Safety Precautions for the AW50N Nailer
Good Working Practices/Safety
The following suggestions will enable you to observe good working practices, keep yourself and fellow
workers safe and maintain your tools and equipment in good working order.

!
WARNING!! KEEP TOOLS AND EQUIPMENT OUT OF THE REACH OF YOUNG CHILDREN
1. KEEP WORK AREA CLEAN... Cluttered areas invite injuries.
2. KEEP CHILDREN AWAY. All children should be kept away from the work area. Don't let them
handle the tool.
3.PRESCRIPTION MEDICATION. Read the warning labels on all medicines to determine if your judgment
or reflexes would be impaired. If there is any doubt, do not attempt to operate this tool.
4. USE EYE PROTECTION. Eye protection should conform to BSI specifications and provide protection
against flying debris from the front and the side. Eye protection should be worn when loading, unloading,
servicing or operating this tool.
5. USE EAR DEFENDERS. Repetitive high noise levels can damage hearing. If the work area in which you
are operating has excessively high noise levels, wear ear protection.
6. NEVER USE OXYGEN, COMBUSTIBLE GASES, BOTTLED GASES OR HIGH PRESSURE
COMPRESSED GAS AS A POWER SOURCE FOR THIS TOOL. The tool may explode and cause
serious injury.
7. WEAR APPROPRIATE CLOTHING. Protective gloves and non-skid footwear/safety shoes are
recommended when operating this tool. Don't wear loose clothing or jewelry. They can get caught in
moving parts. If you wear your hair in a long style, a safety helmet, hat, protective hair covering or even a
sweatband will help to minimise the chance of hair being caught up in the tool.
8. DO NOT FIRE TO HARD MATERIALS. This tool was designed to fire fasteners into wood or like
materials, DO NOT attempt to fire fasteners into hard or brittle materials, such as concrete, ceramics, tiling
or steel.
9. DO NOT OVERREACH. Keep proper footing and balance at all times, do not perform simian acrobatic
feats to get that little bit longer reach, especially when working from ladders or towers, the extra time
required to reposition the tower or ladder is a good trade off against a potentially crippling fall.

TroubleShooting
General Safety Precautions for the AW50N Nailer Continued
10. CHECK THE TOOL FOR DAMAGE. Before using the tool, check for damage, any part that
seems damaged should be carefully checked to determine that it operates properly and will
perform its intended function. If there is any doubt, have the tool repaired and tested by a
suitably qualified person.
11. REPLACEMENT PARTS AND ACCESSORIES. When servicing, only use approved
replacement parts. Only fit the approved accessories intended for use with this tool.
12. STAY ALERT. Watch what you are doing. Use common sense, do not operate any tool if you
are tired or subject to distraction, a fastener fired into any part of your anatomy is not a
recommended experience.
13. STORE IDLE EQUIPMENT. When not in use, the tool should be cleaned, unloaded, lightly
oiled, stowed away in its carrycase, and stored away in a dry location to prevent the possibility of
rusting. The storage position should be out of reach of children.
14. USING OUTDOORS. If the tool and its attendant air compressor are to be used outdoors,
carry out the general safety checks concerned with operating 230V machines, specifically check
plugs, power leads, extension cables and the power supply. Do not operate exposed 230V mains
supplied machines in wet weather conditions and do not trail extension leads across wet or
puddled sites.
I5. AIR LINES AND THEIR CONNECTIONS. Be aware of the position and ‘lay’ of your air lines.
During the setting up procedures for the job, check that the lines will not ‘snag’ during the
expected tool travel. (Curly’s are the worst, aren’t they?). Check all air line connections, ensure
there are no leaks.
16. BE AWARE OF OTHER PEOPLE. Never point the tool at people or animals, even in jest.
17. USE THE CORRECT AIR CONNECTOR. The connector on the tool must not be a non return
type. It must not hold pressure in the gun if the air line is disconnected. If the wrong fitting is
used the tool could remain charged and still have the ability to drive a fastener whilst in an
apparent ‘safe’ condition.
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 TOOL. THEY MUST BE SUPPLIED BY THE OPERATOR.
STOP USING THE TOOL IMMEDIATELY IF ANY OF THE FOLLOWING PROBLEMS OCCUR.
SERIOUS PERSONAL INJURY COULD OCCUR. ANY REPAIRS OR REPLACEMENTS MUST
BE DONE BY A QUALIFIED OR AN AUTHORISED SERVICE CENTRE ONLY.

Initial Assembly
Your air tool is fully assembly when you receive it. All that requires to be done, is for you to select
the method whereby you wish to connect the gun to the air supply system. Assemble the chosen
connector into the 1/4” BSP port in the rear of the handle. If this is the first time that the gun is
being used, introduce a liberal ‘squirt’ of the supplied oil into the connector. As Fig 6. (even if
your air supply system has an in line automatic oiler). Be sure the air line is depressurized when
installing or removing adaptors.

Operating Instructions
Turn the compressor on and set the regulator to the proper pressure for the size and type of
fastener being used.
Make sure the Air nailer is DISCONNECTED from the air supply when loading the fasteners.
Depress the LOCK to release the MAGAZINE SLIDE and pull the magazine slide out fully as
shown in Figure 3.
Place a full clip of the required type and size of fastener onto the MAGAZINE TRAY, (up to 100
fasteners may be loaded in the magazine).
Push the MAGAZINE SLIDE ASSEMBLY forward until it locks.
Connect the tool to the air supply; your air nailer is now ready for use.
Hold the tool by its handle (DO NOT put your finger in the trigger vicinity yet), place the mouth of
the gun where you wish to fire the fastener, press the gun down to the work surface to activate
the “permit” safety. Make sure the gun is straight and upright, now move your finger to the trigger
and fire the fastener home. Be prepared for a certain amount of recoil, especially if driving into
very hard timber. Make sure you control the recoil or you could initiate ‘bounce nailing’. This
happens if the recoil causes the gun to bounce clear of the work surface. If it bounces high
enough to enable the “permit” safety to reset, as the gun comes back down to the worksurface, if
the trigger is still pressed, another nail is fired. This situation can be further exacerbated, if the
second nail strikes the head of the first,….. even greater recoil…………..I leave it to your
imagination. Although this situation can be both annoying and even comical in some aspects, it
can constitute a real hazard, as the gun is effectively ‘out of control’. It can also cause damage to
the “striker”, especially if the gun jams because the nail could not be fired properly. Learn to
control recoil. When the nail has been fired, lift the tool off the work surface.
Note.
It is always a good policy to test the driven depth in a sample piece of wood before
commencing the job ‘proper’. If the fasteners are being driven too far or not far enough,
adjust the regulator (see fig 2a) to provide less or more air pressure, as required. There
is a pictogram above the regulator which shows the direction to turn the regulator in
order to drive the fasteners deeper or less deep. (See figs 2b).
12
The main body is a casting that is extruded into the handle, the cylinder
housing, and the mounting points for the magazine assembly. It has a ‘soft
grip sleeve moulded over the handle portion.
Connection port This is a 1/4” BSP threaded hole which will allow you to mount the connector
of choice, to allow connection to the air supply.
Magazine slide
latch
A sprung loaded thumb latch that locks the magazine slide closed. It is
depressed to unlock the magazine slide to allow it to be withdrawn,
(See fig 1& fig 3) to facilitate the loading and unloading of the magazine.
Magazine
assembly
The magazine assembly is mounted on the nail guide body and supported at
the rear underside of the handle. The magazine basically consists of a flat tray
into which the fasteners are laid, and the magazine slide plate which covers
the fasteners, keeping them flat in the tray. Part of the slide plate mechanism
is a sprung shoe that pushes against the nails in the magazine tray and
forces them into the receiver in the nail guide body.
“Permit” safety
This is a safety device that will only permit the nailer to be fired if the mouth of
the nailer is in contact with the worksurface. It is a metal pressing that is
around and extends below, the mouth of the nailer. It is sprung biased to the
down position. When the gun is pressed down against the worksurface the
safety is pushed up. A lever (part of the pressing) arms the trigger so that the
gun can be fired.
Trigger
Provided it has been armed by the “permit” safety, pressing the trigger will
allow the gun to fire the nail into the material.
Air pulse
divertor
A moulded plastic cover on the top of the main body. It allows the spent air to
be exhausted through the top of the cylinder housing. It can be swivelled
through 360 degrees to direct the air pulse away from the face? hand?
workpiece??? et.al.
Quick unjam
release
Should the nailer suffer a jam, this quick release toggle provides a very fast
and easy way to clear it. Flipping the lever forward releases the front plate,
allowing access to the nail channel and the receiver slot in the guide body.
