The CRB7 is fitted with 5/16” (8mm) diameter
guide rods (5 & 6).
If the router base rod drillings are smaller, fit
the 9/32” (7mm) guide rods.
2. Loosen the Lock Nuts
Using 1 x 1/2” (13mm) spanner, slightly loosen
fixed rod nut (6E) and micro adjuster nut (4B).
Position the router in front of the CRB7.
Align the router base rod drilling (A) with
Adjuster Rod (5).
IMPORTANT
IT IS NOT ESSENTIAL TO CENTER THE
ROUTER CUTTER PRECISELY WITHIN
THE CRB7’S LETTERBOX FOR ANY
OPERATION.

Check that the router cutter will safely align
within the letterbox cross hatch area.
IF IT WILL, GO TO STEP 7.
IF IT WILL NOT, GO TO STEP 5.
Loosen the M5 nut (5B) using a 5/16” spanner.
Move the adjuster rod (5) to the other crank
plate drilling (5E2).
Replace washers and nuts and tighten.
For further adjustment fit the rods in the other
crank plate drillings (5E2 & 6E2).

Align fixed rod (6) with the router base rod
drilling (B), so that both rods are aligned.
Slide the router onto both rods until it stops at
the Bridge end of the CRB7 assembly.
Using 2 x 1/2” (13mm) open ended spanners,
tighten both fixed rod nuts.
Tip: Using two spanners when tightening the
fixed rod nuts will prevent the rod setting being
disturbed.
Both guide rod positions are now set.
Important - Before attempting any
machining pass:
Ensure that the router is securely fitted to the
CRB7 by checking ALL CRB7 fixings, including
router base wing bolts and micro adjuster lock
nut.
IMPORTANT
Follow the below steps in order:
1. Tighten router base wing bolt (A).
2. Finger-tighten fixed rod nut (6E).
3. Tighten router base wing bolt (B).

Tip: Positioning the router base Wing Bolts
towards the bridge end of the CRB7 will increase
micro adjuster accuracy.
Using the index markings
The micro adjuster and bridge have
corresponding red index lines. (1A & 4A)
1 x Micro adjuster rotation = 5/100” (1.25mm).
4 x Rotations = 3/16” (5mm).
Removing the slack from the adjuster
thread.
• Loosen both router base wing bolts and turn
the adjuster (4) in the desired direction to
engage the thread.
• Rotate until index markings (1A & 4A) align.
• Re-tighten the wing bolt on the adjuster guide
rod.
• Should the router cutter need to be adjusted
in the opposite direction repeat the above
step.
Once happy with the rule location:
• Ensure that the baseplate (2) is clean.
• Peel off the self adhesive backing paper.
• Stick in position.
THE LOCK BARS
Use the lock bars (18) to help tighten and
loosed the guide rods.

• Plunge the router cutter to a level just above
the workpiece and lock in position.
• Loosen the router base wing bolt (I6) on the
fixed guide rod (6).
• Lock the router base wing bolt (I5) on the
adjuster guide rod (5).
• Rotate the micro adjuster (4) to move the
router and cutter into position.
• Lock the adjustment in position by tightening
the adjuster nut (4B) against the bridge (1).

Many routers are manufactured with a cast
index line (11A).
• If the router has no index line, draw one
on the base using a fine tip marker pen.

• Fit the cutter to the router and re-fit the
router onto the CRB7.
• Position the CRB7 with a mortise pillar (10)
either side of the work piece.
• Rotate the CRB7 clockwise until both mortise
pillars contact the sides of the workpiece.
• Adjust the cutter position to the mortise
markings, use the micro adjuster if required.
• Lock the router position on both guides rods
using the router wing bolts.
For a deep rebate, several light cutting
passes may be preferred.
Before use, check that the router is firmly
secured to the CRB.

set the anti-tilt Leg depth.
• Lock the anti-tilt Leg in position.
Before routing, check that the bench
surrounding the work piece is smooth, even
and clear of obstacles.
Anti-Tilt Support
The Anti tilt leg is a two part assembly.
Max. Support height = 3 1/8” (80mm)
Min. support height = 5/16” (8mm)
If the mortise is positioned at the end of

When cutting the mortise, ensure an even
pressure is maintained between the
mortise pillars and workpiece.

To avoid splitting the batten, pilot drill and
screw into position by hand.
• Fit the CRB7 to the router.
• Check that the batten (N) slides into the
first groove and moves smoothly along its
length.
• Set the required distance between the router
cutter and batten.
• Use the micro adjuster (4) to finely adjust cutter
position if required.
• Lock the router in position using the router base
wing bolts (I)
The second groove can now be routed.
• Slot the batten into the second groove to rout
the 3rd groove.

Note: The batten profile should copy the size and
shape of the router cutter.
• Test the batten in a sample groove to ensure a
good but not over-tight fit.
• Rout the first groove into the workpiece. Use a
clamp guide or side fence.
• Using 3 x No.6 woodscrews (12) fix the batten to
the underside of the baseplate via hole E & C.

• Slide the router onto the CRB7 guide rods.
• Position the router at the opposite end from
the Bridge (1).
• Lock the router in position using the wing
bolts (I)
The router cutter should just sit safely
within the baseplate ‘letterbox’.
• Fit the offset handle (7) into the bridge and
lock in position using the bridge pinchbolt (3).
Ensure that the CRB7 handle end remains
over the work piece.

• Position the router and cutter as required.
• Lock in position using the router wing bolts.
Tip: To avoid a central drilling in the workpiece,
use a 1/4” (6.35mm) thick overlay secured by
double sided tape. Rout through the overlay and
into the workpiece beneath.

Min. Radius 7” (180mm)
Before routing the circle ensure that:
The hub and rods are securely fastened.
The center and outer section of the
workpiece are supported.
Tip: To ensure a consistent cutting path always
apply a slight pressure away from the Compass
Hub when routing. If it helps, imagine the rods
are a piece of string and you need to keep the
string tensioned to maintain the distance
between pivot point and router.

SAFETY POINTS
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. Read and understand instructions
supplied with power tool, attachment
and cutter.
3. Current Personal Protective Equipment
(PPE) for eye, ear and respiratory
protection must be worn. Keep hands,
hair and clothes clear of the cutter.
4. Before each use check cutter is sharp
and free from damage. Do not use if
cutter is dull, broken or cracked or if
any damage is noticeable or suspected.
5. The maximum speed (nmax) marked on
tool or in instructions or on packaging
shall not be exceeded. Where stated,
the speed range should be adhered to.
6. Insert the shank into the router collet
at least all the way to the marked line
indicated on the shank. This ensures at
least 3/4 of shank length is held in
collet. Ensure clamping surfaces are
clean.
7. Check all fixing and fastening nuts,
bolts and screws on power tool,
attachment and cutting tools are
correctly assembled, tight and to
correct torque setting before use.
8. Ensure all visors, guards and dust
extraction is fitted.
9. The direction of routing must always be
opposite to the cutter’s direction of
rotation.
10. Do not switch power tool on with the
cutter touching the workpiece.
11. Trial cuts should be made in waste
material before starting any project.
12. Repair of tools is only allowed
according to tool manufacturers
instructions.
13. Do not take deep cuts in one pass; take
several shallow passes to reduce the
side load applied to the cutter.
