TROUBLESHOOTING
Fault Cause Remedy
Joint does not fit correctly at the
radius.
Cutter or guide bush is the incorrect
diameter or location pins are not
against the worktop edge.
Check concentricity of cutter with
guide bush. Cutter 12.7mm diameter
with 30mm diameter guide bush.
Ensure location pins touch worktop.
The back edge of the joint does not
line up.
Either the end stop pin or template
was in the incorrect position, or the
worktop has not pushed up against
the end stop pin when the joint was
cut.
Check position of end stop pin and
re-cut joints.
When clamped together, the joint has
irregular gaps.
The guide bush has drifted away
from the edge of the template whilst
cutting either part of the joint, or
wood chips in particle board have
torn slightly.
Check with a straight edge which
part of the joint is uneven and re-cut
(this can only be done on the male
cut), ensuring that the guide bush
is kept against the template by
machining from left to right. Use
abrasive paper to remove torn wood
chips.
Chipped laminate. Can be caused by a blunt cutter or
removing too much material at one
pass or exiting out of postform edge.
Always use sharp cutters and when
cutting through the laminate cut
3-4mm of material. Maintain correct
feed direction to ensure cutter enters
postform edge.
Jig slipping on material. Clamps not secure or too deep a cut
being made or cutter is blunt.
Check clamps for wear. Clamp
securely, take shallow passes, use a
sharp cutter.
Cut joints not square. Router has tilted or operator has
leaned heavily on router causing jig
flex.
Ensure jig is supported and do not
push hard on router taking shallow
passes. Ensure weight of router is
on supported part of jig and that the
router is upright.
Assembled joint not flush or bowed. Worktop different thickness or
worktop not flat (cupped).
Ensure worktop is same thickness
and flat.
