INTRODUCTION
The Airshield Pro is a lightweight Powered
Respirator intended for protection against all
solid dusts. This is combined with full eye and
face protection from impact and chemical liquid
splash.
The Airshield Pro is powered by a rechargeable
battery pack held inside the respirator. Air
is filtered through the respirator to provide a
constant flow of clean air over the face. A face
seal ensures that positive pressure is maintained
within the respirator.
The Airshield Pro has an adjustable headband
and concussion cradle, ensuring a comfortable
fit for most head sizes.
Read this manual before using the Airshield Pro.
It must be fitted and used in accordance with this
manual to obtain the design performance. Use
as part of your maintenance programme.
Denotes risk of electric shock.

Not to be used if the contaminate
is potentially explosive or highly
flammable.
Please read the operating instructions
carefully and keep them together with
the respirator.
Before use fully charge the battery for
24 hours.
In the power-off state there will be a rapid build
up of carbon dioxide and depletion of oxygen
may occur.
Without the face seal fitted no respiratory
protection is to be expected. At very high work
rates and peak inhalation the pressure flow in
the device may become negative.
Ophthalmic spectacles may transmit impacts
from high-speed particles, thus creating a hazard
to the wearer.
Leave the contaminated area immediately if any
of the following conditions apply:
QThe buzzer sounds.
QAny part of the respirator becomes damaged.
QAirflow into the respirator decreases or stops.
QBreathing becomes difficult.
QDizziness or other physical distress or irritation
occurs.

23. Always clamp workpiece being
machined securely.
24. Only use cutting tools for
woodworking that meet EN847-
1/2 safety standards, and any
subsequent amendments.
25. Vibration levels. Hand held power
tools produce different vibration
levels. You should always refer to
the specifications and relevant Health
& Safety Guide.
Routing Safety
1.Read and understand instructions
supplied with power tool, attachment
and cutter.
2.Keep hands, hair and clothing clear of
the cutter.
3.Remove adjusting keys and
spanners. Check to see that keys
and adjusting spanners are removed
from the router tool, cutter and
attachment before turning router on.
Make sure cutter can rotate freely.
4.Noise. Take appropriate measures
for the protection of hearing if
the sound pressure of 85dB(A) is
exceeded. Routing sound pressure
may exceed 85dB(A), so ear
protection must be worn.
5.Eye protection. Always wear eye
protection in the form of safety
goggles, spectacles or visors to
protect the eyes.
6.Respiratory protection. Always wear
a face or dust mask, or powered
respirator. Dust masks/filters should
be changed regularly.
7.Do not switch router on with the cutter
touching the workpiece. At the end of
the cut, release the router plunge and
allow spindle to stop rotating. Never
use the spindle lock as a brake

AIR/PRO
-5-
8.The direction of routing must always
EHRSSRVLWHWRWKHFXWWHU·VGLUHFWLRQRI
rotation. Do not back-cut or climb-cut.
9.Check before cutting that there are
no obstructions in the path of the
router. Ensure there are no obstacles
beneath workpiece when cutting full
thickness, and that a sacrificial work
surface is used.
10.Hold power tool by insulated gripping
surfaces, because the cutter may
contact its own cord. Cutting the “live”
wire may make exposed metal parts
of the powertool “live” and shock the
operator.
11.Use clamps or another practical way
to secure and support the workpiece
to a stable platform. Holding the work
by your hand or against the body
leaves it unstable and may lead to
loss of control.
Router Cutter Safety
1.Cutting tools are sharp. Care should
be taken when handling them. Do not
drop cutters or knock them against
hard objects. Handle very small
diameter cutters with extra care.
Always return cutter to its packaging
after use.
2.Always use cutters with a shank
diameter corresponding to the size of
the collet installed in your tool.
3.The maximum speed (n.max) marked
on the tool, or in instructions or on
packaging shall not be exceeded.
Where stated the speed range shall
be adhered to. Recommended speeds
are shown in the Trend Routing
Catalogue and/or website.
4. Always use router cutters in a router.
Drill and boring bits must not be
used in a router. Router cutters
must only be used for the material
cutting application for which they are
designed. Do not use on metal or
masonry.
5.Never use cutters with a diameter
exceeding the maximum diameter
indicated in the technical data of the
powertool or attachment used.
6. Before each use check that the
cutting tool is sharp and free from
damage. Do not use the cutting tool
if it is dull, broken or cracked or if in
any other damage is noticeable or
suspected.
7. Cutters should be kept clean. Resin
build up should be removed at regular
intervals with Resin Cleaner. The use
of a PTFE dry lubricant will reduce
resin build up. Do not use PTFE spray
on plastic parts.
8.When using stacked tooling (multi-
blade, block and groover etc.) on a
spindle arbor, ensure that the cutting
edges are staggered to each other to
reduce the cutting impact.
9.Cutter shanks should be inserted
into the collet all the way to the line
indicated on the shank. This ensures
that at least
3
¼ 4 of the shank length
is held in the collet. Ensure clamping
surfaces are cleaned to remove dirt,
grease, oil and water.
10. Observe the correct assembly and
fitting instructions in the router
instruction manual for fitting the collet,
nut and cutter.
11. Tool and tool bodies shall be clamped
in such a way that they will not
become loose during operation. Care
shall be taken when mounting cutting
tools to ensure that the clamping is by
the shank of the cutting tool and that
the cutting edges are not in contact
with each other or with the clamping
elements.
12. It is advisable to periodically check
the collet and collet nut. A damaged,
worn or distorted collet and nut can
cause vibration and shank damage.
Do not over-tighten the collet nut
13. Do not take deep cuts in one pass;
take several shallow or light passes
to reduce the side load applied to the
cutter and router. Too deep a cut in
one pass can stall the router.
14. In case of excessive vibrations whilst
using the router stop immediately and
have the eccentricity of the router,
router cutter and clamping system
checked by competent personnel
15. All fastening screws and nuts should
be tightened using the appropriate
spanner or key and to the torque
value provided by the manufacturer.
16. Extension of the spanner or tightening
using hammer blows shall not be
permitted.
17. Clamping screws shall be tightened
according to instructions provided by
the manufacture. Where instructions
are not provided, clamping screws
shall be tightened in sequence from
the centre outwards.
18. Do not touch the cutter immediately
after operation; it may be extremely
hot and could burn your skin.
Using Routers In A Fixed Position
1.Attention should be made to the
+6(·V6DIH8VHRI9HUWLFDO6SLQGOH
Moulding Machines Information Sheet
No.18 and any revisions.
2. After work, release the router plunge
to protect the cutter.
3.Always use a push-stick or push-
block when making any cut less than
300mm in length or when feeding the
last 300mm of the cut.
4.The opening around the cutter should
be reduced to a minimum using
suitably sized insert rings in the table
and closing the back fence cheeks or
fitting a false fence on the back fence.
5.Whenever possible use a work
holding device or jig to secure
component being machined. Ensure
any attachment is securely fitted to
the workbench, with table surface at
approximately hip height.
6.Use a No-Volt Release Switch. Ensure
it is fixed securely, easily accessible
and used correctly.
7.In router table (inverted) mode, stand
to the front right of the table. The
cutter will rotate anti-clockwise when
viewed from top so the feed direction
is from the right (against the rotation of
the cutter). In overhead mode, stand to
the front left of the machine table and
the feed direction is from the left.
8.Do not reach underneath table or put
your hands or fingers at any time in
the cutting path while tool is connected
to a power supply.
9.Never thickness timber between the
back of the cutter and the backfence.
Useful Advice When Routing
1.Judge your feed rate by the sound
of the motor. Feed the router at a
constant feed rate. Too slow a feed
rate will result in burning.
2. Trial cuts should be made on waste
material before starting any project.
3.When using some attachments e.g.
a router table or dovetail jig, a fine
height adjuster is recommended.
4.When using a template guide bush,
ensure there is sufficient clearance
between cutter tip and inside edge
of bush and that it cannot come into
contact with collet and nut. Ensure
cutter and guide bush are concentric.
Router Cutter Repair/Maintenance
1.Repair of tools is only allowed in
accordance with the manufacturers
instructions.
2.The design of composite (tipped)
tools shall not be changed in process
of repair. Composite tools shall be
repaired by a competent person i.e.
a person of training and experience,
who has knowledge of the design
requirements and understands the
levels of safety to be achieved.
3.Repair shall therefore include, e.g.
the use of spare parts which are in
accordance with the specification
of the original parts provided by the
manufacturer.
4.Tolerances which ensure correct
clamping shall be maintained.
5.Care shall be taken that regrinding
of the cutting edge will not cause
weakening of the body and the
connection of the cutting edge to the
body.

To correctly use the airflow indicator, the
respirator should be turned upside down.
Press the red on/off button to switch on.
Tilt or shake the respirator slightly to encourage
the ball to rise to the top of the indicator. If, when
the unit is then returned to an upright position, the
ball remains elevated, the airflow is acceptable.
If the red ball is raised to less than half the height
of the tube then either the battery charge is low
or the filters are blocked and need replacing.
Low Battery Warning
If an audible regular intermittent tone sounds,
recharge or replace the battery pack.
Visual Inspection
QCheck the face seal material for damage.
QCheck the face seal attachment to the
respirator chassis and visor.
QCheck the visor seal for damage.

MAINTENANCE AND CARE
Respirator Cleaning
After using the respirator follow the procedure
below:
Respirator should not be cleaned with
compressed air, solvents, sterilising
by heat or autoclaving, as this will
cause damage.
Precautions are to be taken to
prevent inhalation of harmful dust
or contaminant on the surface or
retained on the filters.
Carefully remove bulk contamination from the
respirator and wipe down with a damp cloth
containing a mild detergent solution.
Gamma sterilisation is effective
but causes embrittlement of plastic
components and is not recommended.
Replace if deficient after the following checks.
1. Excessive abrasion and scratches on the visor.
2. The face seal for its seal to the visor and for
holes.
3. Fit and fastenings to the headband.
Scratched or damaged visor may not
offer full protection and therefore
should be replaced.
Specific Instructions for Cleaning
and Disinfection of Visor
Clean with a damp cloth – do not use
hydrocarbons, chemicals, cleaning fluids or
solvents on the visor. If necessary, a mild
solution of washing-up liquid and warm water
may be used.
Clean and sterilise all parts by wiping down
the visor, face seal and headband with visor
wipes (ref. AIR/WIPE)
(Sodium Hypochlorite or Ethylene Oxide Gas
have also been proved effective).
Do not immerse the respirator in water or any
other fluids.
Do not use organic solvents or abusive
cleaning agents on any part of the
equipment.
After cleaning carry out the functional test.
Charger Cleaning
Dirt and grease may be removed from the
exterior of the charger using a cloth or soft
non-metallic brush. Do not use water or any
cleaning solutions.
