5. Replace bearings.
1. Support or clamp workpiece.
2. Reduce pressure and clamp workpiece.
8. TROUBLESHOOTING
The chisel may also become blue in colour, this is also a normal attribute associated with friction
and resin build up on the cutting face of the tool bit. A dull (blunt) chisel may be detected when the
amount of pressure required to complete a cut becomes excessive.
6.6.
When performing a through mortise, a thin piece of wood must be placed between
the workpiece and the table to prevent the underside of the cut from splintering,
and to protect the work table. In such a case re-set depth stop accordingly.
6.7.
Using the mortiser as a standard pillar drill.
Loosen bushing screw and remove the chisel and drill bit from the chuck.
Wedge the chuck clamp spindle (fig 14.2) into the neck of spare drill chuck (1).
Pass the spindle up through the bushing and lock into chuck (3). Ensure locking screw (4) remains
to hold the bushing in place, BUT, DO NOT tighten the screw on the drill spindle which must remain
free to turn in the bush. A standard drill bit may be used with chuck (1) for drilling. All locks and
guides are used in the same way as mortise drilling.
7. MAINTENANCE
p
p
WARNING!
Ensure the mortiser is switched off and is unplugged from the mains power supply before carrying out any maintenance.
7.1.
Clean and dust the mortiser removing all waste materials.
7.2.
Periodically apply a light coat of past wax to base work surface which will help keep it clean and rust free.
7.3.
Open shaft cover and apply a thin coat of light machine oil to drill bit shaft where it passes through the chisel, but not on the cutting
edge. Also lightly oil rack and pinion gear teeth upon which the main column moves up and down.
