6. Respiratory protection. Wear a face 
or dust mask, or powered respirator. 
Dust masks/lters 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.
8. The direction of routing must always 
be opposite to the cutter’s direction of 
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 sacricial work 
surface is used.
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 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 
power tool 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 3⁄4 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 
tting instructions in the router 
instruction manual for tting 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.
Using Routers In A Fixed Position
1. 1. Attention should be 
made to the HSE’s Safe Use of 
Vertical Spindle 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 
tting 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 tted to 
the workbench, with table surface at 
approximately hip height.
6. Use a No-Volt Release Switch. Ensure 
it is xed 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 ngers 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 ne 
height adjuster is recommended.
4. When using a template guide bush, 
ensure there is sufcient 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 specication 
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.
