safety yoke;
for the maintenance of fastener driving tools, only spare parts specified by the manufacturer or his authorized representative
shall be used;
repairs shall be carried out only by agents authorized by the manufacturer or by other specialists, having due regard to the
information given in the operating instructions;
NOTE: Specialists are those who, as a result by professional training or experience, have sufficient expertise in the field of
fastener driving tools and sufficient familiarity with relevant government al industrial protection provisions, accident
prevention regulations, directives and generally recognized technical regulations(e.g. CEN-and CENELEC-standards),to be
able to assess the safe working condition of fastener driving tools.
2.2 Noise emission
The characteristic noise values for the fastener driving tool have been determined in accordance with EN12549:1999 and EN
ISO4871”Acoustics-Noise test code for fastener driving tools-Engineering method”(see Technical Data).
2.3 Information on mechanical impact (vibration)

instructions.
-
Fig 2
Avoid weakening or damaging the too, for example by:
punching or engraving;
modification not authorized by the manufacturer
guiding against templates made of hard material such as steel;
use the equipment as a hammer;applying excessive force of any kind.
2.5 Safety at work
Never point any operational fastener driving tool at yourself or at any other person or animals.
Hold the fastener driving tool during the work operation in such a way that no injuries can be caused
Fig 3
to the head or to the body in the event of possible recoil consequent upon a disruption in the energy
supply or hard areas within the workplace.（see fig 2）
Never actuate the fastener driving tool into free space. This will avoid any hazard caused by free
flying fasteners and excessive strain of the tool.
The tool shall be disconnected from the compressed air system for the purpose of transportation,
especially where ladders are used or where an unusual physical posture is adopted whilst moving
(see Fig 3).
Carry the fastener driving tool at the workplace using only the handle, and never with the trigger actuated.
Take conditions at the workplace into account. Fasteners can penetrate thin work pieces or slip off corners and edges of
workplaces, and thus put people at risk.
For personal safety, use protective equipment such ad hearing and eye protection (see fig 2)
IMPORTANT: DO NOT direct the adjustable vent hole to the operator or other person or animals during the use.
2.6 Triggering devices
Fastener driving tools are operated by actuating the trigger using finger pressure.
In addition, fastener driving tool is fitted with a safety yoke which enables the driving operation to be carried out only after the
3 Air Nailer MCN90
www.aeroprotools.com
muzzle of the tool is pressed against a work piece, These tool are marked with an inverted triangle(
) behind the serial
number and are not permitted for use without an effective safety yoke.
2.7 Actuating systems
Depending on their purpose, fastener driving tool is fitted with actuating system of single sequential actuation and contact
actuation.
You could switch to one nail figure to choose single sequential actuation, and switch to two nail figure to choose contact
actuation.
- Single sequential actuation: An actuating system in which the trigger and the safety yoke have to be activated so the only one
single driving operation is actuated via the trigger after the muzzle of the tool has been applied to the driving location,
Thereafter further driving operations can only be performed after the trigger has been returned to the non driving position whilst
the safety yoke remains depressed.
-Contact actuation (restricted version):An actuating system in which the trigger and the safety yoke have to be actuated for each
driving operation, with the order of actuation not being specified .For repeated driving operations, it is sufficient if either the
trigger remains activated and the safety yoke is activated thereafter, or vice versa.
Fastener driving tools equipped with contact actuation must be marked with the symbol” Do not use on scaffoldings, ladders’
(see Fig.4) and shall not be used for specific 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.

2 Compressed air system
WARNING
Never free-fire the tool at high pressure.
Proper functioning of the fastener driving tool requires filtered, dry and lubricated compressed air in adequate quantities.
If the air pressure in the line system exceeds the maximum allowable of the fastener driving tool, a pressure reducing valve
followed by a downstream safety valve shall additionally be fitted in the supply line to the tool.
NOTE: When compressed air is generated by compressors, the natural moisture in the air condenses and collects as
condensed water in pressure vessels and pipelines. This condensate must be removed by water separators. These water
separators must be checked on a daily basis and if necessary drained, since corrosion can otherwise develop in the
compressed air system and in the fastener driving tool. Which serves to accelerate wear.
The compressor plant shall be adequately dimensioned in terms of pressure output and performance (volumetric flow) for the
consumption which is to be expected. Line sections which are too small in relation to the length of the line (pipes and hoses), as
well as overloading the compressor, will result in pressure drops.
Permanently laid compressed air pipelines should have an internal diameter of at least 19 mm and a corresponding large
diameter where relatively long pipelines or multiple users are involved.
Compressed air pipelines should be laid so as to form a gradient (highest point in the direction to the compressor).Easily
accessible water separators should be installed at the lowest points.
Junctions for users should be joined to the pipelines from above,
Connecting points for fastener driving tools should be fitted with a compressed air servicing unit(filter/water
separator/oiler)directly at the junction point.

Oilers must be checked on a daily basis and if necessary topped up with the recommended grade of oil (see TECHNICAL
DATA). Where hose lengths of over 10 m are used., the oil supply for the fastener driving tool cannot be guaranteed, We
therefore recommend that 2to 5drops (depending on the loading of the fastener driving tool)of the recommended oil (see
TECHNICAL DATA) should be added via the air inlet of the tool, or an oiler attached directly to the fastener driving tool. (see fig
5)

4 Preparing the tool for use
4.1 Preparing a tool for first time operation
Please Read and observe these Operating Instruction before using the tool. Basic safety measures should always be strictly
followed to protect against damage to the equipment and personal injury to the user or other people working in the vicinity of
operation.
4.2 Connection to the compressed air system
Ensure that the pressure supplied by the compressed air system does not exceed the maximum allowable pressure of the
fastener driving tool. Set the air pressure initially to the lower value of the recommended allowable pressure (see TECHNICAL
DATA).
Empty the magazine to prevent a fastener from being ejected at the next stage of work in the event that internal parts of the
fastener driving tool are not in the starting position following maintenance and repair work or transportation.
Connect the fastener driving tool to the compressed air supply using suitable pressure hose equipped with quick-action
connectors.
Check for proper functioning by applying the muzzle of the fastener driving tool to a piece of wood or wooden material and
actuating the trigger once or twice.
4.3Filling the magazine
Only those fasteners specified under TECHNICAL DATA (see 1.1) may be used
When filling the magazine, hold the tool so that the muzzle is not pointing towards the operator or any other person or animals.
4.4 Handling the tool
Pay attention to 2-Special Reference-of these operating instructions.
Having checked that the fastener driving tool is functioning correctly, apply the tool to a work piece and actuate the trigger.
Check whether the fastener has been driven into the work piece in accordance with the requirements.
- if the fastener is protruding, increase the air pressure in increments of 0.5 bar, checking the result after each new adjustment;
- if the fastener is driven into an excessive depth reduce the air pressure I increments of 0.5 bar until the result is satisfactory.
You should endeavor in any event to work with the lowest possible air pressure. This will give you three significant advantages;
1. Energy will be saved, 2. Less noise will be produced, 3. A reduction in fastener driving tool wear will be achieved.
Avoid triggering the fastener driving tool if the magazine is empty.
Any defective or improperly functioning fastener driving tool must immediately be disconnected from the compressed air supply
and passed to a specialist for inspection.
In the event of longer breaks in work or at the end of the working shift, disconnect the tool from the compressed air supply and it
is recommended to empty the magazine.
The compressed air connectors of the fastener driving tool and the hoses should be protected against contamination, the
ingress of coarse dust chips, sand etc, will result in leaks and damage to the fastener driving tool and the couplings.

5. Maintenance
Disconnect the tool from the compressor before adjusting, clearing jams, servicing &maintenance, relocating and during non
operation.
Regular lubrication, if your tool without using the in-liner automatic oilier, place 2 or 6 drops of pneumatic tool oil into the air
inlet before each work day or after 2 hours of continuous use depending in the characteristic of work piece or type of fasteners.
Air-operated tools must be inspected periodically, and worn or broken parts must be replaced to keep the tool operating
safely and efficiently. Check and change all worn or damaged O-ring, Seals, etc. Tighten all the screws and caps to avoid
personal injury. This should be done by an expert.
Make regular inspection for free movement of trigger, spring and safety mechanism to assure safe system is complete and
functional: no loose and missing parts, no building or stocking parts.
Keep magazine and nose of tool clean and free of any dirt lint or abrasive particles.
When temperatures are below freezing, tools should be kept warm by any convenient, safe method.
