INTRODUCTION

The Airshield 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 is powered by either one or two
rechargeable battery packs inside the respirator.
Air is filtered through the respirator to provide a
constant flow of clean air over the face. A soft
face seal ensures positive pressure is
maintained within the visor and prevents debris
or contaminated air entering the visor area. The
visor is mounted on a fully adjustable headband
providing a comfortable fit for most head sizes.

Typical use for the Airshield Respirator is the
protection of individuals in Agriculture,
Engineering, Pottery, Insulation, Woodworking,
Dental Laboratories, Aerospace and other places
where dust is present. All respirators must be
used in atmospheres containing sufficient
oxygen to support life (usually 17% to 23% by
volume).

All parts, including filters and accessories are
easily changed without the use of special tools
and come packed for immediate use.

Read this manual before using the Airshield. It
must be fitted and used in accordance with this
manual to obtain the design performance. Use
as part of your maintenance programme.

The following symbols are used throughout this
manual:

■ When using a template guide bush
ensure it cannot come into contact
with collet and nut.

■ 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.

-6-

AIRSHIELD

■ Eye protection. Wear safety
goggles, spectacles or visors to
protect the eyes from ejected
waster particles.

■ Respiratory protection. Wear a face
or dust mask, or powered
respirator. Dust masks/filters should
be changed regularly.

■ Do not switch router on with the
cutter touching the workpiece.

■ The direction of routing must
always be opposite to the cutter's
direction of rotation.

■ After work, release the router
plunge and allow spindle to stop
rotating before putting machine
down.

■ Check before cutting that there are
no obstructions in the path of the
router. When cutting through the full
thickness of the workpiece, ensure
there are no obstacles beneath
workpiece, and that a sacrificial
work surface is used.

Additional Safety Rules For
Router Cutters

■ Cutting tools are sharp. Care
should be taken when handling
them.

■ Always use cutters with a shank
diameter corresponding to the size
of the collet installed in your tool.

■ Always run router cutters at the
spindle speed recommended and
marked accordingly. Ensure cutter
has reached correct speed before
entering workpiece. Recommended
speeds can be found on the
packaging, in cutter instructions or
in the Trend Routing Catalogue.

■ Always use router cutters in a
router. Router cutters must not be
used in a drill. 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.

■ Never use cutters with a diameter
exceeding the maximum diameter
indicated in the technical data of
the powertool or attachment used.

■ Do not drop cutters or knock them
against hard objects. Do not use
cutters that are damaged.

■ Cutters should be kept clean. Resin
build up should be removed at
regular intervals with Resin

Cleaner®. The use of a dry
lubricant (Trendicote
act as a preventative. Do not use
PTFE spray on plastic parts.

■ Cutter shanks should be inserted
into the collet to the mark line on
the shank. This ensures that at

3

least

⁄4of the shank length is held
in the collet. Do not over-tighten the
collet nut as this will score the
shank and create a weakness and
fracture point.

■ Observe the correct assembly
instructions in the router instruction
manual for fitting the collet and nut.
Observe the router power tool
manual instructions on fitting
cutters correctly.

■ It is advisable to periodically check
the collet and collet nut. A worn,
distorted or damaged collet can
cause vibration and damage the
shank, and should be replaced.
Worn collet nuts should be
replaced.

■ Do not take deep cuts in one pass;
take several shallow or light passes
to reduce the side load applied to
the cutter. Too deep a cut in one
pass can stall the router.

■ Very small diameter cutters must
be handled and used with care.

■ Always return cutter to its
packaging after use.

■ Should you experience excessive
vibration during use stop
immediately. Have the eccentricity
of the router, router cutter and
clamping system checked.

■ All fastening screws and nuts
should be tightened using the
appropriate spanner or key in
accordance with the manufacturers
instructions.

Using Routers In A Fixed
Position

■ After work, release the router
plunge to protect the cutter.

■ Always use a push-stick or push­block for last 300mm of the cut.

■ Whenever possible use a work
holding device or jig to secure
component being machined.

■ Ensure attachment is securely fitted
to the workbench, with table
surface at approximately hip height.

®

PTFE) will

-7-

■ Ensure a No-Volt Release Switch is
fixed to or adjacent to the
attachment and that it is used
correctly.

■ Check the direction of the
workpiece is always opposite to the
cutter's direction of rotation.

■ Do not use awkward or
uncomfortable hand positions.

■ 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.

Useful Advice When Routing

■ 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.

■ Take many light passes rather than
one deep cut to reduce the side
load applied to both router and
router cutter.

■ Trial cuts should be made on waste
material before starting any project.

■ When using some attachments
including a router table or dovetail
jig, the use of a fine height adjuster
is highly recommended.

■ When using a template guide bush,
ensure there is sufficient clearance
between cutter tip and inside edge
of bush. Ensure cutter and guide
bush are concentric.

Router Cutter Maintenance

■ Composite cutting tools (brazed tip)
must be maintained 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.

■ The design of composite tools must
not be changed in the process of
maintenance.

■ Replacement parts must meet
Trend specification.

■ Tolerances which ensure correct
clamping by the collet shall be
maintained.

■ When re-grinding the tool, care
must be taken not to cause
weakening of the body or the
connection between the cutting
edge and the body.
