Installing the Riser Block
The 34-250 Mortising Machine will accomodate workpieces up to 4-1/4” as preassembled by
the factory. A riser block 1-3/4” tall is provided separately so pieces up to 6” can be mortised.
Below are the steps necessary to add the riser block. NOTE: The fence adjustment knob will
become inoperable with the riser block installed.
1. Locate the riser block, four hex bolts M8-
1.25 x 80, and the long hold down support
rod. (Fig.04)
2. With the aid of another person, separate the
column from the base by removing the four
hex bolts M8-1.25 x 25. (A-Fig.05)

holes of the riser block with the four threaded
holes in the base (C-Fig.06).

Installing the Mortising Chisel and Drill Bit
The 34-250 Mortising Machine uses 5/8” diameter shank chisels with a 3” cutting depth.
Please contact RIKON Technical Support at 877-884-5167 before using chisel sizes other
than provided.
!
• UNPLUG MACHINE BEFORE INSTALLING CHISEL AND BIT SET.
• WEAR PROTECTIVE GLOVES WHILE HANDELING THE CHISEL.
• MAKE SURE DRILL BIT PROTRUDES 1/16” TO 3/16” PAST CHISEL POINT.
WARNING
!
1. Open the chuck access cover (A-Fig.09).
2. Loosen the bushing set screw (B-Fig.09).
3. Open the chuck jaws to allow the drill bit to
pass and chisel to seat properly against the
bushing.
4. Tighten the bushing set screw (A-Fig.10).
5. Using the chuck key, tighten the drill bit
making sure that 1/16” to 3/16” of the drill bit
point is lower the the chisel point. This
distance will depend on wood hardness and
mortising depth requirements. (B-Fig.10)

6. To square the chisel to the fence rst tighten
the fence lock levers (A-Fig.11). Next place a
square against the fence and chisel. If an
adjustment is needed, loosen the bushing set
screw (B-Fig.11) and rotate the chisel until
square. Tighten the bushing set screw.

Adjustments
Fence Adjustments
The fence should travel square in the adjustment slots in the base casting. It will also adjust
back and forth on a rack gear with the use of the fence adjustment knob. See steps below.
NOTE: The fence adjustment knob will be inoperable with the riser block installed.
1. Take a measurement from each fence side to
the milled edge of the base casting (A-Fig.12).
if the measurements do not match, loosen
the four bolts holding the column to the base
casting (B-Fig.12). Rotate the fence and
column assembly until both measurements
match.

2. To adjust the fence, rst loosen the two lock
levers shown in gure 12. Next, turn the fence
adjustment knob (A-Fig.13) and position the
fence as necessary. Tighten the two lock
levers to hold the fence into position.
NOTE: The fence adjustment knob will be
inoperable with the riser block installed.
3. The hold down is a clamp that pressures the
workpiece against the table surface. It will
stop the workpiece from lifting as the
mortising chisel is removed from the cut.
The hold down can accomodate taller
worpieces but turning upside down. (A-Fig.14)

Operation
This manual is not a training aid. There should be some basic understanding regarding
operation prior to using a mortising machine. Tips on usage can be found in books,
researching the internet and other resources.
1. Mark your mortise depth on the side of your
workpiece. The depth of the mortise should
be set to the chisel point, not to the tip of the
drill bit. The extra depth cut by the drill bit will
allow room for excess glue.
Fig.15
2. Set the depth stop while holding the chisel at
the desired depth. Loosen the lock handle
(A-Fig.16). Next, lower the depth stop rod
until it makes contact with the top of the
column casting (B-Fig.16).
3. Place the workpiece against the fence. Move
the fence forward and center the chisel with
the mortise to be cut. Lock down the fence
(A-Fig.17) then position the hold down on top
of the workpiece. Lock the hold down
(B-Fig.17). Start the mortiser and feed the
chisel into the workpiece. Feed the chisel to a
depth of 1/2” then retract to allow the chips to
clear. Allow the chisel to do the work. Do not
force the cut or the motor will slow down.

Wiring Diagram
WARNING:This machine must be grounded.
Replacement of the power supply cable should only be done by a qualied electrician.

Electrical Requirements
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not t the outlet, have the proper outlet installed by a
qualied electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface that is green with or without yellow stripes, is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do
not connect the equipment-grounding conductor to a live terminal.
Check with a qualied electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Use only three wire extension cords that have three-prong grounding plugs and three-pole
receptacles that accept the tool’s plug.*
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet that looks the one illustrated in Figure
A below. The tool has a grounding plug that looks like the grounding plug as illustrated in Figure A
below. A temporary adapter, which locks like the adapter as illustrated in Figure B below, may be
used to connect this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet
is not available.** The temporary adapter should only be used until a properly grounded outlet can
be installed by a qualied electrician. The green colored rigid ear or tab, extending from the adapter,
must be connected to a permanent ground such as a properly grounded outlet box.
* Canadian electrical codes require extension cords to be certied SJT type or better.
** Use of an adapter in Canada is not acceptable.
