EXTENSION CORD USAGE
Extension cords are not recommended for use with this bench grinder. Extension
cords, if used, must be properly grounded with a 3-prong plug on one and a 3-hole
receptacle on the other. DO NOT use grounding adapters with an extension cord.
Extension cords must be UL listed and use a minimum of 18 A.W.G. wiring.
Extension cords should never exceed 25 feet in length. Extension cords, that are too
long, cause a voltage drop over the extra distance causing the grinder motor to run
slower with the possibility of causing damage to the motor. Using extension cords
with smaller than the recommended wire gauge run the risk of getting too hot, melt-
ing, and/or causing fires. See table, “Extension Cord Specifications”, on page 18.
IMPORTANT SAFETY RULES FOR BENCH GRINDERS
ALWAYS wear protective eyewear and/or appropriate dust filters and respirator
when using this tool.
DO NOT OPERATE THIS BENCH GRINDER until it is completely assembled
according to the instructions in this manual. Failure to adhere to these instruc-
tions could result in serious and/or permanent injury.
OBTAIN ADVICE FROM A QUALIFIED INDIVIDUAL if you are not completely
sure how to use the bench grinder.
USE RECOMMENDED ACCESSORIES. Consult the owners manual for recom-
mended accessories. The use of improper accessories may cause cause risk of
injury.
NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if
the cutting tool is unintentionally contacted.
CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part
that is damaged should be carefully checked to determine that it will operate
properly and perform its intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts, mounting and any other con-
ditions that may affect its operation. A guard or other part that is damaged
should be properly repaired or replaced.
DIRECTION OF FEED. Only feed work into a blade or cutter against the direc-
tion of rotation of the blade or cutter.
GROUNDING INSTRUCTIONS
The electrical power source for this bench grinder MUST be grounded in order pre-
vent possible electric shock or even death should the tool malfunction or break-
down. Grounding provides a path of least resistance for electric current thus reduc-
ing the risk of electrical shock. The power source must also use a minimum 20A
service and not used if other power tools on the same circuit are in use.
This bench grinder is equipped with a grounded 3-wire power cord with a 3-prong
plug. If the power cord will not fit into the wall plug, an approved adapter can be
used as long as it is connected to the center screw in the wall plate. Never modify
the electrical plug by cutting off the grounding prong so it will fit into unapproved,
un-grounded electrical receptacles. See Figure 1.
If you have questions about hooking up the bench grinder, contact a certified elec-
trical contractor to install the proper circuitry acceptable for this and other power
tools you use. Repair or replace any damaged electrical wiring IMMEDIATELY.
