Use and Care Manual

Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than
150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
8-1. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown in
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. Note: In Canada, the
use of a temporary adaptor is not permitted by the
Canadian Electrical Code, C22.1.
3. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating between
150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in D, Figure
8-1. The tool has a grounding plug that looks like the
plug illustrated in D. Make sure the tool is connected
to an outlet having the same configuration as the
plug. No adapter is available or should be used with
this tool. If the tool must be reconnected for use on
a different type of electric circuit, the reconnection
should be made by qualified service personnel; and
after reconnection, the tool should comply with all
local codes and ordinances.

8.2 Extension cords
The use of extension cords is discouraged; try to
position machines near the power source. If an
extension cord is necessary, make sure it is in good
condition. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. Table 1 shows correct size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

9.0 Setup for operation
9.1 Spoil board preparation
The sacrificial, or “spoil,” board prevents damage to
the cutter as it cuts through the work material. A
spoil board must be flat and smooth.
The CNC router table is provided with 1-inch thick
MDF spoil board strips. An initial fly cut is strongly
recommended to remove any marks and create a
perpendicular surface to the cutting path. Cut only
the minimal amount to create a flat surface (0.020
inch recommended).
(NOTE: A pre-set program is available for flycutting
your spoil board with a 1-1/2 inch flycutting bit.
Contact Powermatic customer support to
download.)
Workpieces may be secured to spoil board using
hold-downs (provided) in the table T-slots, if the
outer edges of workpiece are not being machined
(Figure 9-1). Additional hold-downs (p/n 1797000,
set of 2) are available from Powermatic.
Figure 9-1: optional clamping method
Alternatives include drilling the work directly to the
spoil board, or securing it using double-sided tape.
Make sure spoil board is clean and no chips or
sawdust are beneath the tape. The finished
workpiece can be removed from the board using a
wide putty knife or similar tool.
