Grounding Instructions

This
grounded while in use to protect the user from
shock
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.
If you are not sure whether your outlet is properly
grounded, consult a qualified electrician.
Referring to Figure 9: As received from the factory,
your mortiser is ready to run at 115-volt operation.
This mortiser is intended for use on a circuit that
has an outlet and a plug that looks like the one
illustrated in (A). A temporary adaptor, which looks
like the adaptor shown in (B), may be used to
connect this plug to a two-pole receptacle if a
properly grounded outlet is not available. The
temporary adaptor should only be used until a
properly grounded outlet can be installed by a
qualified electrician. This adaptor is not applicable
in Canada. The green colored rigid ear, lug, or tab,
extending from the adaptor, must be connected to
a permanent ground such as a properly grounded
outlet box.

Operating Controls

Start/Stop Switch

Referring to Figure 10:
The Start/Stop switch is located to the left of the
motor. Flip the switch out to start; flip in to stop.
The yellow insert is a switch lock which prevents
the mortiser from being started when removed.

Adjustments

Depth Stop Adjustment

A depth stop is provided to limit the depth, or
downward travel, of the chisel. This enables the
operator to make repeated boring operations
without the need to measure each bore. To adjust:
1. Loosen the lock handle (A) and bring the depth
stop (B) to rest at the bottom of the column.
2. With the operating handle (C) lower the
head (D) until the chisel (E) is at the desired
depth.
3. Bring the depth stop (B) up until it comes to
rest against the bottom of the head (D).
4. Tighten the lock handle (A).
