10. MAINTENANCE
10.1 BLADE REPLACEMENT/ADJUSTMENT –
FIGS. 11 – 14
Note: only use sharp blades.
Switch off the power supply and disconnect the mains
lead before carrying out any maintenance operations.
Warning!
The blades are extremely sharp, so care must
be taken at all times.
Using the supplied blade spanner
, loosen the bolts
which will release the tension on the blade. When
the blade is loose slide it out.
Loosen the two grub screws
(Fig.12) anticlockwise
until they are flush with the surface of the clamp block
. Insert the new blade making sure of the correct
orientation (inset fig.13)
ie. the groove down the back
of the blade is NOT against the clamp block.
Adjust the bolts to grip the blade loosely so that it stays
in place, but still allowing ease of movement for setting
up the blade height/level.
Adjust the front sole plate so that it is lower than the
rear plate to avoid interference.
Place a straight edge across the rear sole plate
and
cutter block.
By screwing the grub screws clockwise equally, raise the
blade up gradually. Keep checking the blade height by
moving the cutter block round by hand to see if the
blade scrapes on the straight edge. Set the blade so that
it just touches the straight edge (Fig.14). Make this
check at three points across the blade to ensure a
correct and equal level is achieved. When adjustment is
complete, one end of the blade must be in line with the
rebating side of the rear sole plate.
Warning!
After having completed this operation,
ensure that the blade and blade support are securely
fastened in the cutter block, if not, serious accidents
may occur.
Warning!
Due to the forces and vibration which are
experienced by the cutter block, it is recommended that
a suitable thread locking compound be applied to the
blade adjustment grub screws. For this reason it is also
important before each use to inspect the blade set up.
