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.
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 rat-
ing 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.
•
•
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.
CAUTION
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.

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 damaged 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.
WARNING
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.
Use of undersize extension cords result in low voltage to the motor that can result in motor burnout and pre-
mature 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.
