12) Ground an electrically powered Floor Grinder
motor securely. Determine that any “grounding” wire
and/or device is, in fact, properly grounding the motor.
Failure to properly ground the motor may cause
an electrical shock and/or electrocution, resulting
in property damage and personal injury including
death. Electrical wiring and all connections should
be performed by a qualified electrician. operating the
electric motor from an improper voltage/amperage
power source can result in property damage and/or
personal injury.
13) When operating an electrically powered Floor
Grinder on a surface containing water or other
electrically conducting liquid, special precautions
must be taken to minimize the possibility of operator
electrocution. one such precaution is to wire and
operate the electric motor from a clean, 20 Ampere,
115 volt AC, power source in conjunction with a
ground fault circuit interrupter (GFCI). A GFCI is a
safety device that disconnects power from a circuit to
a load when a potentially dangerous condition occurs.
The GFCI opens the circuit when the fault current flow
from a power line to a ground exceeds the safe limit for
humans. The GFCI protects against harmful electrical
shock to a person caused by contact with a defective
electrical product. A GFCI differs from a fuse or circuit
breaker. A fuse or circuit breaker opens the circuit
when the total current flow in the power line exceeds
the safe limit of the power line. They are designed
to protect against fire caused by overheating of the
power line. use of a GFCI gives on the job protection
from electrical shock hazards caused by ground faults
in commercial, industrial and residential applications.
They are simple and easy to use: plug a portable GFCI
into any suitable, grounded extension cord and plug
the Floor Grinder into the GFCI for automatic protection
against ground faults. For specific information, consult
current National Electrical Code® publications and
oShA publications 210-22D (or current revision) for
construction sites and 555-3 (or current revision) for
use around any area containing water.
14) Never exceed the recommended capacities of the
Floor Grinder. Refer to the Specifications section of
this manual for more detailed information.
OPERATION
1) Give complete and undivided attention to the job at
hand. Do not chew gum, smoke and/or use smokeless
tobacco while utilizing the Floor Grinder. Do not
attempt to eat and/or drink while utilizing the Floor
Grinder. Determine that eyeglasses and/or hearing aid
devices and other medical related devices are properly
secured. Keep shoes properly laced. use of the Floor
Grinder is strenuous and causes fatigue. help prevent
the cause of an accident. Plan to take work brakes as
required to help maintain proper mental and physical
alertness.
2) This Floor Grinder is not sealed or insulated. Do
not operate this machine in an explosive atmosphere
or near combustible materials. Refer to current oShA
and National Electric Code® rules and regulations.
3) The Floor Grinder is designed for use by one
operator. use of the Floor Grinder by more than one
operator can lead to confusion and loss of control,
resulting in property damage and/or personal injury.
Never operate the Floor Grinder with an improper
number of operators. Such a configuration can result in
property damage and/or personal injury. If it is felt that
more than one person is required to operate the Floor
Grinder, SToP and contact the Customer Service
Department for specific operational and service/
maintenance information. There is no charge for this
service.
4) Do not operate the Floor Grinder with onlookers
close by. Caution all onlookers to stand clear. The
grinding process can result in flying particles being
emitted at high velocity and striking the operator and/
or onlookers This can lead to the possibility of property
damage and/or personal injury. Wear proper safety
eyewear Keep all body parts, loose clothing and
foreign objects clear of the rotating disc.
5) Start the engine or electric motor according to the
instructions as outlined in this manual to minimize the
possibility of unexpected contact with the work surface.
unexpected contact with the work surface can cause
the loss of machine control and the possibility of
property damage and/or personal injury.
6) Start and operate a Floor Grinder or a vacuum
system that is powered by a gasoline engine only
in a well ventilated area. Carbon Monoxide fumes
given off by an engine are poisonous. Breathing
these fumes can result in property damage and/
or personal injury. operate the Floor Grinder only
when/where visibility and light are adequate for the
job at hand. Work carefully. Always hold the operator
handle firmly with both hands. Wrap your fingers
around the handle, keeping it cradled between your
thumbs and fingers. Always make sure the operator
handle is in good condition and free of moisture, pitch,
oil or grease. Wear gloves to improve your grip. Never
leave the Floor Grinder running unattended.
