ELECTRIC MOTOR SAFETY
For maintenance care and operation of the electric motor, refer to your electric motor instruction booklet
furnished with the electric motor. Protect the electric motor from dust as much as possible and keep
ventilating openings clean.
CAUTION
• DO NOT spray water on the electric motor. Do not touch the plug with wet hands. To
reduce the risk of electrocution, keep all connections dry and off the ground.
• DO NOT operate electric motor in an explosive environment.
WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identified
by a marking, "Acceptable for use with outdoor appliances; store indoors while not in use." Use only
extension cords having an electrical rating not less than the rating of the product. Do not use dam-
aged extension cords. Examine extension cords before using and replace if damaged. Do not abuse
extension cords and do not yank on any cord to disconnect. Always disconnect the extension cord
from the receptacle before disconnecting the product from the extension cord.
Electric Motor Connection
ALWAYS make certain that the power source required for the electric motor is correct and always
use the correct NEMA configuration plug. Motors can burn out when the line voltage falls 10% below
the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat. Make
certain that the correct size grounded (3-wires) extension cord is used. See the table below.
To choose the proper extension cord:
•
Locate the length of extension cord needed
in table to the right.
•
Once the proper length is found, move
down the column to obtain the correct
AWG size required for that length of
extension cord.
WARNING
Use of undersize extension cords result in low voltage to the motor that can result in motor burnout
and premature failure. MK Diamond warns that equipment returned to us showing signs of being run
in a low voltage condition, through the use of undersized extension cords will be repaired or replaced
totally at the customers expense. There will be no warranty claim.
NOTICE
Most Motor Problems are caused by improper
voltage and extension cords. Cord should be
one-piece and short as possible. Cord
selection should match the following table.
