WORK LIGHT
The bench grinder is provided with a flexible work light to
assist in visibility of the workpiece.
The bench grinder is provided with a light bulb for the flex-
ible work light. Screw bulb into housing.
WARNING:
To reduce the risk of fire, use a 120 volt, 25
watt or less track light bulb, Type S11, intermediate base or
equivalent.
DO NOT
use a light bulb that extends past the
end of the light housing.
CAUTION:
The flexible work light housing will remain hot
for a few minutes after turning grinder “OFF”. Avoid contact
with housing until it is cool.
INSTALLATION
MOUNT GRINDER
Grinder must be mounted to a solid horizontal surface
(hardware not provided). To mount grinder to metal pedestal
stand:
• Align mounting holes with corresponding holes in
pedestal
• Insert a ¼-20 x 1¼” hex head bolt with flat washer
through base of grinder.
• Place a ¼” flat washer and ¼”-20 hex nut from the bot-
tom of pedestal onto the bolt.
• Tighten until base is flush with the pedestal.
• Using second nut on each bolt, jam tighten against the
first to prevent loosening by vibration.
To mount grinder to wooden bench:
• Use ¼ x 1¼” wood screws with flat washers beneath
heads.
• Tighten screws until base is flush with bench top.
GROUNDING INSTRUCTIONS
WARNING:
Improper connection of equipment grounding
conductor can result in the risk of electrical shock.
Equipment should be grounded while in use to protect oper-
ator from electrical shock.
• Check with a qualified electrician if grounding instruc-
tions are not understood or if in doubt as to whether
the tool is properly grounded.
• This grinder is equipped with an approved 3-conductor
cord rated at 150V and a 3-prong, grounding type plug
(See Figure 4) for your protection against shock hazards.
• Grounding plug should be plugged directly into a proper-
ly installed and grounded 3-
prong grounding-type recepta-
cle (See Figure 4).
• Do not remove or alter grounding prong in any manner.
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electrical shock.
WARNING:
Do not permit fingers to touch the terminals
of plug when installing or removing from outlet.
• Plug must be plugged into matching outlet that is prop-
erly installed and grounded in accordance with all local
codes and ordinances. Do not modify plug provided. If it
will not fit in outlet, have proper outlet installed by a
qualified electrician.
• Inspect tool cords periodically, and, if damaged, have
repaired by an
authorized service facility.
• Green (or green and yellow) conductor in cord is the
grounding wire. If repair or replacement of the electric
cord or plug is necessary, do not connect the green
(or green and yellow) wire to a live terminal.
• Where a 2-prong wall receptacle is encountered, it must
be replaced with a properly grounded 3-prong receptacle
installed in accordance with National Electric Code and
local codes and ordinances.
WARNING:
This work should be performed by a qualified
electrician.
• A temporary 3-prong to 2-prong grounding adapter (See
Figure 5) is available for connecting plugs to a two pole
outlet if it is properly grounded.
• Do not use a 3-prong to 2-prong grounding adapter
unless permitted by local and national codes and ordi-
nances.
(A 3-prong to 2-prong grounding adapter is not permitted
in Canada.) Where permitted, the rigid green tab or ter-
minal on the side of the adapter must be securely con-
nected to a permanent electrical ground such as a prop-
erly grounded water pipe, a properly grounded outlet box
or a properly grounded wire system.
• Many cover plate screws, water pipes and outlet boxes
are not properly grounded. To ensure proper ground,
grounding means must be tested by a qualified electri-
cian.
