Hollow chisel mortiser

6. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply chapter 1 safety instructions before use.
p
6.1
Ensure you have installed the correct chisel and that it is sharp.
View fig 13 and note that the chisel opening is to the right (A). This means that after the first
incision is made, the workpiece should be moved to the right for subsequent cuts.
This will allow waste chips to freely pass through the opening in the chisel.
6.2
Set the depth gauge.
6.3
Place your workpiece in the mortise machine adjusting the back stop (5), and clamp (10) and depth
stop as necessary.
6.4
Plug the mortiser into the mains power supply. Hold the workpiece firmly against the back
stop and switch the mortiser on, keeping hands and fingers away from the cutting tools.
6.5
Bring the handle down to commence mortise cutting. We recommend that you practice on
scrap wood before moving onto an actual workpiece. The rate of chisel penetration must be
fast enough to prevent burning the drill and chisel tip, but not too fast as to stall the motor. You
may notice smoke coming from the bit or the wood once the chisel has engaged in the
workpiece. This is a normal occurrence of hollow chisel mortising caused by chipping
friction whereby the wood resins in the stock are burned off. Should this become
excessive however, refer to troubleshooting chapter 9.
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.
Attach the chuck clamp spindle (fig 14.2) to the neck of spare drill chuck (1).
Pass the spindle up through, 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 for mortiseing.
7. MAINTENANCE
WARNING! Ensure the mortiser is switched off and is unplugged from the mains power supply before carrying out any maintenance.
p
p
7.1
Clean and dust the mortiser, removing all waste materials.
7.2
Periodically apply a light coat of 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.
