SAFETY PRECAUTIONS
Always switch off the power and unplug the router when changing cutters or when making
adjustments.
Always wear protective goggles when routing.
Wear sound protective ear muffs when routing
for long periods of time.
Always wear a dust mask. Use dust extraction equipment whenever possible.
Do not wear loose clothing. Make sure baggy sleeves are rolled up and ties are removed.
Always remove spanners and hex keys from the workpiece before switching router on.
Keep hands well clear of the router cutter when routing.
Avoid accidental starting of the router. Make sure the power switch is in the ‘Off’ position
before plugging in and connecting to the electrical supply.
Never leave the router unattended when running. Always wait until the router comes to
a complete stop before making adjustments.
Do not switch the router on with the cutter touching the workpiece.
Mount the router table securely to a work bench.
Periodically check all nuts and bolts to make sure they are tight and secure.
Cutter Care
Do not drop cutters or knock them against hard objects.
Cutters should be kept clean. Resin build-up should be removed at regular intervals with
Resin Cleaner
®
. The use of a dry lubricant will
act as a preventative such as Trendicote
®
PTFE spray. Do not use PTFE spray on plastic components.
Cutter shanks should be inserted into the collet at least 3/4 of shank length to prevent
distortion. A distorted collet should be discarded, as it can cause vibration and
damage the shank.
Do not over-tighten collet as this will score the shank and create a weakness there.
It is also advisable to periodically check the router collet nut for wear.
Useful Advice
Judge your feed rate by the sound of the motor. In time, the operator will acquire a ‘feel’
for the router, and a feed speed relative to the work will come naturally. Too slow a feed will result in burning.
Apply the normal precautions as with any electric power tool.
The main abuse of routing machines is the inclination for operators to overload them. The
motto is ‘Keep the revs up’. The drop in revolutions should not exceed, if possible, more than 20% of full running speed.
The motor of a router is susceptible to the accumulation of sawdust and wood chips, and
should be blown out, or ‘vacuumed’, frequently to prevent interference with normal motor ventilation.
Refer to the Instruction Manual supplied with your router for full details of it’s features and
safety information.
Trial cuts should be made on waste material before starting any project.
Do not store the router on the floor, as chippings, pins or dirt can drop into the air
intake of the router.
IMPORTANT: To move table with leg stand fitted, please lift. Do not drag.

Special note for Bosch POF routers
For the Bosch POF range of DIY routers a packing piece must be made in 3mm to 6mm thick plywood or MDF. This is then placed between the underside of the plate in the table and the underside of the router base. The fixing screws can then be used. Enlarging the aperture in the base of the router is also advised if large diameter tooling is to be used.

Identification of Router Mounting Holes and Screws (see pages 8 & 9).
Identify the mounting holes and fixing screws (including washers & nuts if router base
requires re-drilling) which will be required to suit your router.
Identify whether your router or the fixing plate requires re-drilling.
Bolt the router onto the fixing plate first with the operating controls to the front, before
fitting to the table.
The fixing plate is symmetrical therefore once the router is mounted to it, it can be fitted to
the router table in four different positions. The orientation of the plate depends on which router is fitted. It is advisable to position the plate so that controls for speed or height are easily accessible.
IMPORTANT! Some routers may require the removal of the plastic base slider to allow fitting to plate.
IMPORTANT! Carry out the following re­drilling only if required.
Re-drilling Router Base Only
Invert and stand your router onto a suitable surface.
Place the fixing plate facing upwards onto the base of your router.
Identify holes 1 and 2, or holes 3 on fixing plate (Ref. CRT/FP/A see page 8).
Fit a large diameter cutter (max. 53mm Ø) into your router and tighten collet.
Retract plunge mechanism and lock off allowing cutter to protrude through the base.
Adjust position of the fixing plate to centralise the cutter within the centre hole.
Take care not to damage cutter or to touch sharp edges.
Ensure that the holes you are about to drill in the base do not interfere with any of the
features on the router or any webbings in the casting of the router base. A slight turning of the plate may be required to miss such obstructions.
Mark the centre of the holes onto the base.
Remove plate and mark the centre of the
holes with a centre punch.
Drill a hole at these points with a 6mm diameter drill bit.
Clean up edges of holes if required.
Re-drilling Fixing Plate Only
Remove the plastic base of the router. Alternatively a photocopy or an outline of the
base can be made of the plastic base instead.
Draw cross lines onto the plastic base of the router.
Draw cross lines on the fixing plate with a pencil. These cross lines should bisect the
plate on both sides.
Packing piece
Page 8
-7-
CRT MK2
Align the lines on the fixing plate with those on the plastic base and secure the fixing
plate to the plastic base.
Using a centre punch, mark the centres of holes.
Drill the required hole size with a suitable metal cutting drill bit. Best results will be
obtained if your power drill is mounted in a drill stand.
Countersink the hole with a countersink bit to a depth so the heads of the screws are
slightly below the top surface. Clean off any burrs created.
IMPORTANT! If you do not have the necessary equipment to carry out these operations, then a local engineering shop will be able to carry them out accurately for you.
Re-drilling both Fixing Plate and Router Base
Invert the router and lay the fixing plate onto the upturned base.
Clamp the fixing plate and router base together with two cramps.
Ensuring that the drill bit will not foul any webbing or fixtures on the router base, drill
with a 6mm diameter metal cutting drill bit
into the fixing plate and through the router base two holes approximately 75mm apart.
Unclamp the router base and fixing plate.
Countersink the fixing plate holes with a
countersink bit to a depth so the screw heads are slightly below the top surface. Clean off any burrs created on both the fixing plate and router base.

Mounting the No-Volt Release Switch
The no-volt release switch serves as start-up protection. When the router is plugged in and
its on/off switch depressed, the router starts only after the green switch is pressed.
Switch off the router using the red button.
Attach the no-volt release switch to the table
leg with the screws provided.
Plug the router into the socket.
IMPORTANT: Always remove the plug of the No-Volt Release Switch from the power source before making any adjustments.

Guard Operation
When routing with the top guard, never reach under the guard or swing the guard away. The guard should not be removed from the back fence and should always be used in the lowered position.
Cutter Rotation
Feed Direction
Feed Direction
Always work with constant, medium rate. Feeding too slow will results in burn marks
and excessive heat build up of the cutter.
Good results will be obtained by removing small amounts of material in several passes.
Always feed work in the opposite direction to the direction of rotation of the router cutter.

ADJUSTMENT
Fence Adjustments
To make adjustment to the lateral movement of the back fence:
Release the back fence knob.
Loosen the two screws that secure
the adjustable wedge.
Adjust position and re-tighten screws.
Re-tighten the back fence knob.
The back fence can be adjusted forwards and backwards, using the graduated scales to gauge the depth of mould.
For edge moulding, position the back fence with the fastening bolts towards the front of the slot.
For panel grooving (i.e. routing of grooves away from the edge of the workpiece) the fastening bolts should be to the rear of the holes and slots.
Workpiece Support
The workpiece support provides safe guiding of the workpiece when routing the complete edge of the surface.
Adjustment range from: 0 to 12.7mm (1/2”)
Cutting Depth/Cutting Height
Before starting to work:
Adjust the cutting depth (A) by adjusting the
position of the back fence.
Adjust the cutting height (B) by raising or
lowering the cutter using a fine height
adjuster (if fitted). Alternatively rapid height
adjustment can be made if a PlungeBar is
fitted.

OPTIONAL ACCESSORIES
Hose and Connector - CRT/3 & CRT/4
The back fence is provided with an extraction point for connection to suitable vacuum extractors. The internal hole diameter is 58mm (2 1/4"). Suitable fittings with 58mm outside diameter are available for most extractor units.
Only a vacuum extractor unit recommended for use in the workshop should be used.
A suitable adaptor and extraction hose can be purchased as optional accessories.
The hose (Ref. CRT/4) has an outside diameter of 39mm and inside diameter of 32mm. The hose adaptor (Ref. CRT/3) is a three piece design that allows the hose to swivel freely.
Assemble the hose adaptor onto the end of the hose as shown and insert into back
fence.
Fit the other end of the extraction hose to your dust extractor.

Profiling Top Guard - CRT/2
Remove the back fence and assemble the profiling top guard as shown.
The use of the optional profiling top guard is recommended when profiling of workpieces workpieces with a pin or ball bearing guided cutter. It will prevent the operator's fingers inadvertently contacting the cutter while providing good visibility.
Pages 26 and 27 describe a typical application involving using ball bearing guided cutters with to make a shield.
Spring Pressure Clamps - CRT/10
The optional spring pressure clamps can be mounted to the back fence. When adjusted to suit the width and thickness of the workpiece, they ensure the workpiece is held down onto the surface to obtain accurate machining of the workpiece.
Remove back fence from table surface and assemble as shown.
Adjustment
The spring pressure clamps will require adjusting to suit the height and width of
workpiece being routed.
The pressure strips should provide enough pressure to prevent the workpiece lifting
from the table surface, but not too much as to create friction which would prevent the workpiece from sliding freely.
The horizontal bar with pressure strip fitted can be removed from the vertical pillars
when not required. The vertical pillars can be left in position and will not impede the tenon push bock system.

Vertical Routing Support - CRT/5
For safe routing of narrow panels a vertical routing support is available.
Assemble the support as shown.
Adjust the depth of cut and router cutter
height making sure the router is unplugged when making these adjustments.
The vertical routing support should be positioned to guide the workpiece but allow it
to slide freely.
It is important to check that the entire length of the workpiece will travel between the fence
and the support without binding. This is done simply by holding the workpiece up to clear the router cutter and passing it through the cutting area to ensure no binding occurs.
Once the vertical routing support is positioned correctly lock it into place securely
by tightening both knobs so that the vertical routing support will not move.
IMPORTANT: Do not overtighten the knobs as this may result in damage.

OPERATION
Edge moulding with the back fence
Mark the width and depth of cut required onto the end of the timber and place it up
against back fence.
Release back fence fixing bolts and
adjust position until required width of cut is achieved.
If pin or ball bearing guided cutters are used, ensure that the back fence is in line with the guide or slightly behind it. The back fence will give more support and provides the retractable safety guard and spring pressure clamp facility.
Lock back fence fixing bolts.
Release plunge mechanism on router
and adjust the depth of cut using the fine height adjuster or PlungeBar (if fitted).
Lock-off plunge mechanism of router.
Lower guard and check it will retract freely
over the workpiece.
Adjust the spring pressure clamps (if fitted) to suit the thickness and width of the
timber.
Ensure that you have the pushstick within easy reach when routing.
Switch on router and pass timber over cutter with a consistent feed speed.
Ensure even pressure is kept on the workpiece down onto the table and against
the back fence.
IMPORTANT:
Before making adjustments isolate the router and no-volt release switch from the power supply.
Always ensure that hands are never near the cutter.
Use the push stick to safely maintain pressure on narrow timbers.
Useful Advice
Make a test cut on a piece of waste material prior to carrying out any routing operation.

Grooving with the Back Fence
The router table can be used for operations away from the edge of the workpiece such as grooving, fluting, veining, etc.
When routing, always feed against the rotation of the cutter. This direction is marked on the back fence.
For maximum accuracy, one edge of your workpiece (the edge sliding against the fence) must be true and straight.
Set up the back fence as follows:
Raise safety guard and rest it against the extraction point.
Position the fence behind the router bit for the desired cutting depth (the distance of cut
from the edge of the workpiece).
Securely tighten back fence fixing bolts and lower the guard over the cutter.
Make the cut by sliding the straight edge of workpiece against the fence. Use the pushstick as shown.
Full edge moulding using the Workpiece Support
The workpiece support can be used to plane an edge.
The cutter should be set approximately 2mm proud of the back fence.
The workpiece should be routed until the planed edge passes onto the out-feed fence.
Retract workpiece away from cutters and switch off router.
Replace workpiece and bring workpiece support out until it touches.
Tighten knob and continue routing.
IMPORTANT!
Never push small or narrow workpieces by hand past the router cutter, unless a jig or pushstick/pushblock is used.
Always work with the guard lowered.
Adjust the cutting height and depth only when the power has been isolated and the router cutter stops rotating.
Page 23
Across grain routing with the mitre fence
The mitre fence will be required to give extra support for routing small workpieces or ends of large workpieces.
It is advisable to fit a waste piece of material to the mitre fence or behind the component to prevent break-out of the wood grain.
If using mitre fence to trim the end off a piece of material, the workpiece support can be brought forward with the cutter to support the workpiece after the cut.
IMPORTANT! Align back fence with the mitre bar slot before using mitre fence.
Stopped Moulding
Right hand (A) and left hand (B) stops, constructed from scrap timber, must be attached to the back fence using clamps. These stops limit the movement of the workpiece, and should be set to suit the required stopped mould length.
1. Swing in the workpiece around the corner
(C) keeping the workpiec edge (D) up against the right hand stop (A), until the router cutter plunges into the workpiece.
2. Rout the complete length of the workpiece,
until the workpiecetouches the left hand stop (B).
3. Swing out the workpiece (D) around the
corner point (C).
IMPORTANT! There is a danger of kick-back, unless the stops are used.

Tenon Cutting using the Push Tenon Block
The tenon push block facility is ideal for producing tenons and sliding dovetails.
IMPORTANT! The retractable guard cannot be used when carrying our push block operations. Therefore extra care must be taken to ensure that hands are kept well clear of the cutter.
Ensure that the workpiece is true and the end is square and smooth.
Mount push block assembly on the back fence.
Adjust the height and depth of the cutter to suit the cut required.
Position workpiece between clamp plate and push block so that it's side is flush against the
face of the back fence, and the end to be cut is resting on the table. Clamp workpiece in this position by tightening the wing nut on the clamp rod while making sure that clamp plate stays orientated on the workpiece.
Slide push block and workpiece back to the start position. When routing, always feed
against the rotation of the cutter.
Switch router on and guide the push block against the back fence with both hands,
keeping fingers at a safe distance from cutter.
Switch router off, unclamp workpiece and slide push block back to its original position.
Position and re-clamp each side of workpiece and repeat cutting operations.
Useful advice.
When setting up, a piece of paper placed between the compact and table top will give sufficient gap to slide properly.
A scrap piece of timber should be placed behind the workpiece to prevent break-out.
Page 25

Routing without a Back Fence
IMPORTANT! There is an increased danger of injury since the router cutter is freely accessible from all sides.
Fit the profiling top guard for protection and the lead-on pin to prevent kick-back.
Only use router cutters with a ball bearing or pin guide.
Always work against the direction of rotation of the router cutter.
Mounting a Lead-on Pin
The lead-on pin should be screwed into the table top as shown and tightened with a flat
screwdriver.
The pin is used as a guide for the workpiece when the cut is first made. Correct working procedure for this is critical especially when using large diameter cutters.
Profiling Working Procedure
Switch router on and allow it to reach full running speed.
Position the workpiece against the lead-on pin as shown. The workpiece should not
contact the cutter.
Gradually swing workpiece towards cutter until workpiece or template engages the ball
bearing or pin guide.
Feed workpiece against the rotation of the cutter whilst swinging the workpiece away
from the lead-on pin. At this point the ball
Page 26
-25-
CRT MK2
bearing is acting as the guide.
Progressively feed the workpiece anti­clockwise around the shape of the
template ensuring that the ball bearing always stays in contact with the workpiece.
When the complete edge of the workpiece has been machined, slide it
away from the cutter.
If you are unfamiliar with the above procedure then the technique should be
practised before switching on the router.
Helpful Advice
Always keep the workpiece moving in a precise steady movement to prevent the
workpiece from burning.
Never let go of the workpiece. Always keep an even pressure of the workpiece
against the bearing. Do not use too much pressure.
If you wish to stop routing halfway through the operation. Simply slide the
workpiece away from the cutter before switching off the router.
If the workpiece inadvertently comes away from the ball-bearing and so does
not complete the cut correctly, do not stop. Complete the operation and repeat the procedure for the edge concerned.
It is usually advisable to repeat the operation in order to improve the finish
of the workpiece.
Keeps hands away from the cutter, even if the guard is fitted, in order to give a
good safety margin.
If natural woods are used, consideration should be given to break-out of short
grain which will effect your decision as to where to start the routing operation in order to prevent it.

EXAMPLE APPLICATION
Producing a Shield
Construct an actual size template of the design from 6mm MDF or plywood ensuring
that it is accurate and free from imperfections.
Fix the template to the back of the workpiece to be used using screws or double sided
tape.
Rough cut the workpiece to the shape of the template using a band saw or jigsaw leaving
2-3mm oversize.
Fit a ball bearing guided trimmer cutter.
Lay the workpiece (with template fitted) face
down on the table surface. Adjust the height of the cutter. Ensure that the ball bearing will contact the template and the cutting edge of the cutter will machine the full edge of the workpiece.
Fit the profiling top guard and adjust height to give a 6mm gap between the top of cutter
and underside of template.
Switch router on and position the workpiece against the lead-on pin as shown. The
workpiece should not contact the cutter.
Rout the shield using the procedure described on the previous pages.
Useful advice
If natural woods are used, consideration should be given to break-out of short grain which will effect your decision as to where to start the routing operation in order to prevent it.
Moulding the Shield
A suitable ball bearing guided cutter should be chosen to mould the shield.
Fit chosen moulding cutter and adjust height of cutter to achieve shape required.
If the full edge of the workpiece is to be machined, leave the template attached to the
workpiece so as to provide a guide for the ball bearing. Otherwise the template can be removed, providing there is sufficient edge for the ball bearing to follow.
Repeat the same routing procedure as
before.
If the profile required involves excessive removal of material, it is advisable to take two passes with the cutter. First reduce the height of the cutter protruding from the table, this in effect, reduces the amount of material which will be removed, or fit a larger ball bearing, if one is available for that particular cutter.
The second pass can then be made to give the required finish.
Carrying out this two stage routing operation has many advantages.
Improved finish on workpiece
Less load on cutter and router
Far less risk of workpiece snatching
Definition of Snatching
This can be described as the cutter catching the workpiece and projecting it away from the direction of rotation. The workpiece is often taken from the operator's hands and projected across the work area. It can have potentially dangerous consequences if the cutter is unguarded and/or the operator's hands are too close to the cutter. Damage to the cutter can also be caused.
The following precautions should be made to

avoid a potentially dangerous situation:
Fit the profiling top guard, this will prevent fingers contacting the cutter.
Always rout in the direction which opposes the direction of rotation of the cutter.
Routing with the direction of the cutter is called back-cutting and will cause snatching and therefore should not be carried out.
Use the lead-on pin to provide support for the workpiece during the initial start of the
routing operation, it will also ensure that you approach the cutter from the correct side.
When a deep cut is required or the workpiece is particularly dense, then take
two or three passes.
Ensure the cutter always has sharp cutting edges.
Useful advice
Do not reduce pressure of the workpiece or let go of it. Always keep both hands on the
workpiece and keep an even pressure against the ball bearing.
Do not use too great a feed speed. If the revolutions of the router drop, it is a good
indication that either too deep a pass is being made and/or the cutter is blunt. Therefore reduce the depth of cut and/or re­sharpen your cutter.
If the above points are followed, profile routing using bearing guided cutters is both safe and rewarding. It is however advisable for those new to routing to avoid using larger diameter cutters until proficient with the technique described. Under no circumstances should this type of operation be attempted with cutters not having a ball bearing or guide pin.
