off position.
6.1 GROUNDING INSTRUCTIONS
This tool must be grounded. 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 fit the
outlet, have the proper outlet installed by a qualified
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 qualified
electrician or service pe r sonnel if the grounding
instructions are not completely understood, or if
in doubt as to whether the tool is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in Figure 9-
1. The MBS-1018-1 has a grounding plug that looks
like the plug illustrated in Figure 9-1. 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.
If hardwired:
Permanently connected tools: This tool should be
connected to a grounded metal permanent wiring
system; or to a system having an equipment-
grounding conductor. Make sure a disconnect is
available for the operator. During hard-wiring of the
machine, make sure the fuses have been removed
or the breakers have been tripped in the circuit to
which the drill press will be connected. ALWAYS
FOLLOW PROPER LOCK-OUT/TAG-OUT PRO-
CEDURES.

6.2 Voltage conversion (MBS-1018-3
only)
1. Reconnect leads in motor junction box
according to diagram inside junction box cover.
Diagrams are also found at back of this manual.
(If discrepancies should occur, diagrams on
machine take precedence.)
2. Reconnect leads on transformer in electrical
box.
3. Reconnect leads to coolant pump according to
diagram inside pump junction box cover.
4. If using a plug, connect a proper UL-listed plug
for the incoming voltage.
Make sure incoming current matches power
requirements of saw. If saw blade does not move in
proper direction, disconnect machine from power
supply and reverse any two of the three power leads
(except green ground wire).
6.3 Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary, be
sure it is 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 2 shows recommended 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.
