GROUNDING INSTRUCTIONS

This machine must be grounded while in use to protect the operator from electric shock.

4 - English

1. All grounded, cord-connected machines:

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 machine 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 fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in 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 qualified electrician or service personnel if the grounding instructions are not completely understood, or if in

doubt as to whether the machine is properly grounded. Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that

accept the machine’s plug, as shown in Fig. A. Repair or replace damaged or worn cord immediately.

Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine

will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter

illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. B if a

properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can

be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be

connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held

in place with a metal screw. NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

Fig. 20

Fig. 21

You can move the fence (A) Fig. 22 in or out by loosening the lock handles (B), and rotating the fence rack handle (C). Tighten the handles (B) after the move.

NOTE: The levers (B) are spring-loaded and can be repositioned. Pull out on the lever and reposition it on the serrated nut located underneath the lever.

10 - English

Fig. 22

ADJUSTING THE HOLD-DOWN

The hold-down (C) Fig. 23 prevents the workpiece (E) from lifting as the chisel rises out of the hole. To adjust the hold-down, loosen the handle (F), position the holddown so that it just touches the top of the workpiece (E), then tighten the handle. You can turn the hold-down (C) upside down to accommodate thicker workpieces.

Fig. 23

ADJUSTING THE CHISEL PARALLEL TO THE WORKPIECE

You can adjust the chisel (A) Fig. 24 parallel to the workpiece by loosening the screw (B) and rotating the chisel until the back surface of the chisel is touching the workpiece. Tighten the screw (B).

ADJUSTING THE SLIDING FIT BETWEEN THE HEAD AND THE COLUMN

A dovetail gib (A) Fig. 25 ensures a good sliding fit between the head and the column. Make the adjustment by loosening the two screws (B) and turning the adjusting screws (C). Tighten the two screws (B).

NOTE: The adjustment is correct when no side movement between the gib and the column is evident. Adjust the gib so that is is not so tight as to restrict the sliding movement or so loose that it affects accuracy.

Fig. 24

1. Keep chisels and bits sharp.

2. A typical mortis operation is illustrated in Fig. 26. Note that the opening (A) in the chisel is to the right. Move your workpiece from left to right for subsequent cuts to allow chips to escape freely.

3. Hold the workpiece firmly against the fence. Ensure that

the hold-down (B) Fig. 28 is properly adjusted. The rate of penetration of the chisel must be fast enough to prevent burning at the tip of the bit, but not too fast as to stall the motor. You may encounter smoke from the bit or the workpiece. Smoke is a natural operating occurrence, caused by friction and burning of resins. Bluing of the chisel after initial use is not indicative of a dull chisel, but rather is a combination of friction and built-up resin on the cutting face of the chisel. You can detect a dull chisel by the amount of excess force required to complete a cut.

4. When performing a through mortise, place a thin piece of wood between the workpiece and the table to prevent

“chip-out” at the bottom of the mortise.

ROTATING THE COLUMN 180 DEGREES

The column (A) Fig. 27 can be rotated 180 degrees for special cuts. To rotate the column, remove the four screws, two of which are shown at (B), rotate the column (A) 180 degrees, and replace the four screws (B).

You must secure the base to a supporting surface.

USING BITS WITH EXTRA LONG SHANKS

When using bits with extra long shanks, remove the extension (A) Fig. 28. Insert a screwdriver into the slot (B) Fig. 29 in the end of the armature shaft on top of the motor. Use a chuck key to unscrew and remove the chuck (C) Fig. 28 and extension (A). Remove the extension (A) from the chuck (C) and replace the chuck (C). You can also use the chisel spacer. Place the chisel spacer (D) Fig. 30 on the chisel shank (F) and insert the chisel into the chisel holder. Tighten the chisel holder securely.
