OpERATION & MAINTENANCE
OpERATION
Raising and Lowering the Head
The head (A) Fig.11 is raised and lowered by means of the lever (B). For maximum
leverage during the mortising operation the lever can be repositioned by pulling out the
hub (C) of the lever assembly and repositioning the hub on the pinion shaft (D).
Depth Stop
A depth stop (E) Fig.11 is provided to limit the depth of the chisel (F). Put a mark on an
easily accessible end of the workpiece to be mortised, at the depth you require. Loosen
the depth stop lock knob (G) and lower it down. Pull the head down, and put the end of
the wood against the chisel. Position the head so that the chisel points or the bit point
are at the depth required. Raise the depth stop (E) and position it up against the un-
derside of the head and retighten the depth stop lock knob (G).
Fence and Hold Down
The fence (A) Fig.12 can be moved in or out by loosening the lock handle (B) and turn-
ing the adjustment knob (C) until you reach the desired position, retighten lock handle
(B) once the adjustment is done.
The hold down (D) Fig.12 can be raised and lowered by loosening the lock handle (E).
OpERATIONAL HINTS
Make sure that the chisels and bits being used are sharp.
Make sure the workpiece is held firmly against the fence and under the hold down. The
rate of penetration of the chisel must be fast enough to prevent burning at the tip if the
bit, but not too fast as to stall the motor. You may encounter smoke from the bit or ma-
terial once the chisel has engaged the material. The smoke created is a natural oper-
ating occurrence in hollow chisel mortising and is caused by material chip friction and
the resins in the stock being burned off. Bluing of the chisel after the initial use is not
indicative of a dull chisel, it is indicative of too much heat which will lead to premature
dulling and resin buildup on the cutting faces of the chisel. A dull chisel can be detected
by the amount of excess force required to complete a cut.
When performing a through-mortise, a thin piece of wood (1/4”-1/2” thick) should be
placed between the workpiece and the wooden table and a depth stop adjustment
should be made to prevent “chipout” at the bottom of the mortise and also to prevent
damaging the wooden table.
MAINTENANCE
There is very little maintenance required on your mortiser. Keep it clean, make sure
the rack and pinion gears do not become clogged with chips/sawdust. Lightly spray oil
on all exposed metal surfaces and moving parts if the machine is going to stand idle
for any length of time. Keep the chisels and bits sharp.
