Maintenance
Before any intervention on the
machine, disconnect it from the electrical
supply by pulling out the plug or switching off
the main switch! Failure to comply may cause
serious injury.
General
A coat of paste wax applied to the table and
column will help to keep the surfaces clean.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
The Mortiser requires only minor maintenance,
such as cleaning and lubrication and routine
adjustment and sharpening of the chisel and
auger.
Dust the machine down after each use and, as
necessary, use light applications of oil or grease to
lubricate linkages, moving parts, etc.
Sharpening Chisel and Auger
The chisel and auger should be kept sharp for best
performance. Blunt edges will give inaccurate
mortises and can lead to overheating and
breakage to chisel or auger. If chisel and auger are
badly worn and become difficult to sharpen, they
should be replaced.
Auger
Sharpen the auger by using a small, smooth file,
following the original shape of the auger. File the
inside edge of the spur, the sides of the brad point,
and the cutting edge inwards toward the flute of
the auger (Figure 16).
Do not file the outside edge of the spur, as this will
affect the diameter of the auger.
Chisel
Referring to Figure 17:
Sharpen the chisel (A) with the chisel sharpening
cone (B) located on the top of the column next to
the tool holder. Set the chisel (A) on the
sharpening cone (B) and rotate back and forth until
sharpened (C).
Note: Make sure the set-screw is tight to prevent
the cone from spinning.
Using a fine stone or micro-abrasive on a flat
surface, lap the outside faces of the mortise bit to
remove any burrs.

Lubrication
All of the ball bearings are packed with grease at
the factory. They require no further lubrication.
Periodically grease the gears, racks, and table
pivot points with a #2 tube grease.
Periodically clean and oil any exposed machine
surfaces, such as: dove-tail ways and slides, and
table surface.
Storage
If the mortiser will be stored for an extended
period, use the depth stop to help secure the head
in position; this will relieve stress upon the
hydraulic cylinder.
