7.4.2 Extension cords
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
7.4.1 Grounding instructions
This machine 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.
The Pneumatic Shear is equipped with a 15 amp
cord and plug set, with a grounding prong. The
plug must be plugged into a matching outlet that is
properly installed and grounded in accorda nce with
all local codes and ordinances. Do not modify the
plug provided – if it will not f it 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
cond uctor 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 equipmentgrounding 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 tool is properly grounded. Repair or replace a
damaged or worn cord immediately.
The use of an extension cord is not recomm ended.
Try to place shop equipment within reach of the
power source. If an extension cord becomes
necessary, make sure the cord rating is suitable for
the amperage listed on the machine’s motor plate.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Use the chart in Figure 17 as a general guide in
choosing the correct size cord. If in doubt, use the
next heavier gauge. The smaller the gauge
number, the heavier the cord.
