which cannot be completely excluded by
safety mechanisms. Power tools must
therefore always be operated with
caution!

General

1. Disconnect power tool and attachment

from power supply when not in use,
before servicing, when making
adjustments and when changing
accessories such as cutters. Ensure
switch is in “off” position. Always
ensure cutter has stopped rotating.

2. Always mount the power tool,

accessory or attachment in conformity
with the instructions. Only use
attachment and accessories specified
in the power tool manual. The tool or
attachment should not be modified or
used for any application other than
that for which it was designed. Do not
force tool.

3. Keep children and visitors away. Do

not let children or visitors touch the

recommended when working
outdoors. Wear protective hair
covering to contain long hair.

5. Consider working environment. Do

not use the product in the rain or in a
damp environment. Keep work area
well lit. Do not use power tools near
gasoline or flammable liquids. Keep
workshop at a comfortable
temperature so your hands are not
cold. Connect machines that are used
in the open via a residual current
device (RCD) with an actuation
current of 30 mA maximum. Use only
extension cables that are approved for
outdoor use.

6. The accessory or attachment must be

kept level and stable at all times.

7. Keep work area clean. Cluttered

workshops and benches can cause
injuries. Ensure there is sufficient
room to work safely.

8. Secure idle tools. When not in use,

tools should be stored in a dry and
high or locked up place, out of reach
of children.

9. For best control and safety use both

hands on the power tool and
attachment. Keep both hands away
from cutting area. Always wait for the
spindle and cutter to stop rotating
before making any adjustments.

10. Always keep guards in place and in

good working order.

11. Remove any nails, staples and other

metal parts from the workpiece.

12. Maintain tools and cutters with care.

Keep cutters sharp and clean for
better and safer performance. Do not
use damaged cutters. Follow
instructions for lubricating and
changing accessories. Keep handles
dry, clean and free from oil and
grease.

13. Maintain accessories. Do not use

damaged accessories. Only use
accessories recommended by the
manufacturer.

14. Check damaged parts. Before

operation inspect the attachment, the
power tool, the cable, extension cable
and the plug carefully for signs of
damage. Check for alignment of
moving parts, binding, breakage,
mounting and any other conditions
that may effect its operation. Have any
damage repaired by an Authorised
Service Agent before using the tool or
accessory. Protect tools from impact
and shock.

15. Do not use tool if switch does not turn

it on or off. Have defective switches
replaced by an Authorised Service
Agent

16. Don't over reach. Keep proper footing

and balance at all times. Do not use
awkward or uncomfortable hand
positions.

17. Don’t abuse the cable. Never carry

power tool or accessory by cord or
pull it to disconnect from the socket.
Keep cord from heat, oil and sharp
edges. Always trail the power cord
away from the work area.

18. Connect dust extraction equipment.

If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used.

19. Check all fixing and fastening nuts,

bolts and screws on power tool,
attachment and cutting tools before
use to ensure they are tight and
secure. Periodically check when
machining over long periods.

20. Stay alert. Watch what you are doing.

Use common sense. Do not operate
tools when you are tired, under the
influence of drugs or alcohol.

21. Personal Protective Equipment (PPE)

for eye, ear and respiratory protection
must be worn. All PPE must meet
current UK and EU legislation.

22. Do not leave tools running

unattended. Do not leave tool until it
comes to a complete stop.

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.

MANU/COM651 v2.0 25/10/06 3:00 pm Page 2

-3-

COMBI 651

6. Respiratory protection. 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

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 sacrificial 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
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

⁄4of 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.

15. 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. 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
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.

3. 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.

4. 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.

5. Tolerances which ensure correct

clamping shall be maintained.

6. 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.

Sub-base Sets

To obtain a perfect accurate close fitting joint, a
30mm guide bush must be used. The guide bush
must always be fitted concentric with the cutter.
This can be achieved using Trend sub-bases and
30mm outside diameter guide bush ref. GB30.

Trend sub-bases have a central recess to allow
fitting of the Trend guide bush to most makes of
routers and are available ready to fit the most
popular makes.

Two types are offered GB/5 and UNIBASE.

All sub-bases contain screws, a line up bush and
pin. The line up pin and bush ensure exact
alignment of sub-base with router spindle, when
fitted with the relevant collet.

Panel butt connectors are essential for
connecting worktops. They fit into the recess on
the underside of the worktop and are tightened
with a 10mm spanner. The jig has integral bolt
recess slots to allow the bolt recess to be cut in
the underside of the worktop, using the standard
router cutter. The recess is elongated to allow
easy access for the spanner.

Biscuit Jointer for the Router

Ref. 342X1/2TC

ASSEMBLY

Location Bush Identification

Three location bushes are used in different holes
in the jig to align the correct template aperture
for the application.

The holes are colour coded for easy
identification with dots as follows:

Green dot – Female Joint
Red dot – Male Joint
Yellow dot – Connector Recess
White dot – Curved Peninsular

The jig has a colour coded key on its label for
quick reference.

Setting out the Joints

When cutting a joint ensure location bushes
contact the postformed edge of the worktop. For
certain joints the worktop will need to be inverted
so that all cuts are made into the postformed
edge, never out through it. When routing worktop
the balancing paper on the underside may feather
edge – this feather edge should be removed with
abrasive paper.

Location bushes are held in position by ‘O’ rings.
Insert the smallest end of the bush into the hole
by lightly pushing and turning at the same time.
If the bushes are tight use a lubricant on the ‘O’
ring. Ensure bushes are fully home before use.
When using jig ensure location bushes do not
foul workbench.

23mm

In order to prevent breakout of the
laminate, rotation of the cutter and
feed direction must always be into the
postform edge of the worktop.

Margin Distance

Allow 8.5mm when cutting joints. Measure or
use a batten of this
thickness to aid
setting out.

Length Stop Arrangement

OPERATION

Setting the Length Stop for the
Female Joint

Carry out the setting operation first:

■ Fit bushes into Red dot location holes and

offer the jig to the worktop as shown. The
Green dot location holes will be
uppermost.

■ Position the jig across the width of the
worktop. Loosely fit the length stop.

■ Fasten length stop to template so that it
traps the template across the worktop
between the Red dot location bushes and
the stop. Tighten up the knob.

■ Remove the bushes from Red dot location
hole. The template is now set to cut the
correct length of joint.

COMBI JIG

COMBI JIG

Female Joint

■ Fit two location bushes in Green dot holes.
(The Green dots must be uppermost.)
Leave the length stop bush in position.

■ Place the template onto the worktop to be
cut, ensuring the location bushes are
touching the worktop. Now cramp securely
in position using two quick action clamps
ensuring they will not foul the router path.

■ Set cutter depth.

■ Plunge router and cut joint in a series of

passes, feeding left to right. At the end of
each cut release plunge.

When cutting a joint, hold the router
guide bush hard against the template
and cut from left to right. It is
recommended that the depth stops of
the router are used to set the depths of
cut. Several shallow passes of the
router should be made and it is not
necessary to lean heavily on the router
or the jig. Allow the weight of the router
to rest on the part of the template which
is resting on the worktop. Ensure router
remains parallel and upright at all times.

Male Joint

Depending on accessibility lay female worktop
into position on units. Lay male worktop on top
and support other end. Using a pencil draw
round the female cut onto the male. If
inaccessible lay female onto male. Depending on
a right or left hand joint, the pencil line may need
to be transferred on to the other side. Due to the
difference between the cutter and the guide bush
diameters, the cutter path will be 8.5mm over
from the edge of the template, therefore either
measure 8.5mm or use a packing piece of this
size to offset the template by this amount to
ensure the cutter cuts along the pencil line.

The postformed edge of the worktop must always
be in contact with the location bushes, this means
that to cut a male right hand joint, the worktop
must be inverted. Remembering to cut into the
postformed edge.

■ Insert two location bushes into holes marked

Red dot. Face marked Red dot must be
uppermost.

■ Remove the length stop from the female and fit
to the male side of template. Place template
across the width of the worktop and tighten the
knob. Now clamp securely to worktop.

■ Cut the male joint before finally cutting the
worktop to length. All cuts must be fed left

It may not be possible to position all joints at 90°,
in this case it is the male part of the joint that has
to be adjusted.

The length stop has a mitred end which is used to
set up for an out-of-square joint up to 3°.

To mark out an out-of square joint, first lay the
female worktop on the cupboard carcass in its
correct position. Next lay the male section of the
worktop on the carcass and on top of the female
section of the worktop. Support the other end of
the male worktop. Using a pencil and from
underneath the worktop mark around the female
joint onto the male section of the worktop, if
access is difficult lay the female worktop onto the
male worktop, support other end and mark with
pencil from above. This drawn line is the male
cut line.

■ Insert both location bushes into Red dot
holes. Red dot face uppermost.

■ Lay jig across the worktop, ensure the
location bushes touch the postform edge.
Clamp jig in position with quick action clamps.
Draw a line 8.5mm away from the jig slot
edge.

■ With the mitred end of the length stop facing
towards the back of the worktop, as shown.
Fit the length stop onto underside of jig by
using the countersunk bolt, washer and knob
into one of the holes in the jig. The bolt
should be put into the jig from above, do not
tighten. Carefully position the point of the
length stop so that it lines up with the 8.5mm
margin pencil line. When the correct position
has been obtained tighten bolt and knob
sufficiently to prevent length stop from
moving.

■ Remove location bushes.

■ Lay jig with length stop set onto male work

top that is to be cut. Allowing for the 8.5mm
margin and using the length stop as a pivot
point (pivot point on cut line), position the jig
so the jig slot edge is parallel to the drawn
pencil line. Re-check positioning.

■ Clamp jig to worktop securely using quick
action clamps.

■ Remove length stop and bolt assembly as
these are for setting up only and are not
required when routing

■ Set cutter depth.

■ Plunge router and cut the male joint, feeding

left to right in a series of shallow passes,
feeding left to right.

Cutting the Bolt Recesses

When the joint has been tested, proceed as
follows to cut the recess for panel butt
connectors on the underside of the worktop.
The same cutter and guide bush are retained
and used with the integral bolt recess slots in the
jig to produce the recesses for the panel butt
connectors. The bolt recess position can be
gauged approximately 150mm from the edge of
the postform edge, or where access is possible
with kitchen units. Mark with pencil both
positions on the underside of the worktop.

Insert the location bushes into the Yellow dot
holes as shown.

■ The template may need to be inverted
when cutting some bolt recesses.

■ Securely clamp jig to worktop.

■ The bolt recesses should be

approximately 20mm deep although
this will depend upon the thickness
of worktop.

■ Once one bolt recess is cut move jig
over to the remaining pencil lines and repeat.

■ Repeat the procedure for the male joint.

Best results are achieved when the
centre line of the bolt corresponds to
the centre line of the worktop. Clamp
jig securely to worktop.

Strengthening the Joint

If the joint between the worktops is not supported
underneath, after some time the joint may ‘sag’
and become misaligned; to reduce this the joint
should be reinforced with a loose tongue or
biscuit dowels. The biscuit jointing cutter set
Trend Ref. 342 can be used with a portable
router. The size of biscuit used should be No.

20.

Ref. BSC/20/100 (100 biscuits)
Ref. BSC/20/1000 (1000 biscuits)

A 650mm worktop should have at least 5
biscuits.

Sealing the Joint

The cut edges of the joint should be coated with
a water-resistant adhesive, or Trend Fill & Seal
before assembly, to prevent moisture seeping
into the core of the worktops, which would swell,
and disfigure the worktop.

Use a fine grit abrasive paper to clean up the
torn wood chips of both mating surfaces. Lightly
run the abrasive paper along the edges to de-nib
the cut chipboard edge. This will ensure a tidy
joint is achieved.

When cutting the curved peninsular, hold the
router guide bush against the edge of the
template. Cut from left to right.

It is recommended that depth stops are used
and at least three or four cuts taken. White
dots must be uppermost when routing.
