Because each shop situation is unique, no list of safety guidelines can ever be complete.
The most important safety feature in any shop is the knowledge and good judgement of the user.
Use common sense and always keep safety considerations, as they apply to your individual shop situation first
and foremost in mind. If you have any doubts about the safety of an operation you are about to
perform: STOP! Do not perform the operation until you have validated from qualified individuals
if the operation is safe to perform and what is the safest method to perform it.
1. LIMIT EXPOSURE TO DUST
Some dust created by power sanding, sawing,
grinding, drilling and similar operations contains
chemicals known to the state of California to cause
cancer, birth defects or other reproductive harm.
Some examples include:
• Lead from lead-based paint.
• Crystalline silica from bricks, cement and
other masonry products.
• Arsenic and chromium from chemically
treated lumber.
Your risk from these exposures varies depending on
how often you do this types of work. To reduce your
exposure to these chemicals, work in a well ventilated area and work with approved safety equipment
such as dust masks that are specially designed to
filter out microscopic particles.
2. ALWAYS USE EYESHIELDS, WHEEL GUARDS AND
SPARK GUARDS
The supplied eye shields, wheel guards and spark
guards should be maintained, properly installed on
the unit and used at all times.
3. REPLACE DAMAGED PARTS OR COMPONENTS
IMMEDIATELY
Damaged parts or components may lead to a hazardous situation that could cause serious injury.
Replace any damaged parts or components before
operating the unit.
4.
INSPECT GRINDING WHEELS BEFORE EACH USE
Handle grinding wheels carefully. A damaged or
chipped grinding wheel can discharge debris
towards the operator at high speeds. Before
installing or replacing a grinding wheel as well as
before each use, take a moment to inspect the
grinding wheel(s) for cracks, chips or other visible
signs of damage. Do not use a damaged wheel.
Tighten the spindle nut enough to hold the grinding
wheel firmly but do not over tighten as excessive
clamping force can damage the wheel. Use only
the wheel flanges provided with the grinder and do
not remove the blotter or label on either side of the
grinding wheel. When replacing a grinding wheel
select only wheels that are rated to a higher maximum R.P.M. than the maximum of the Bench Grinder.
5. ADJUST TOOL RESTS AND SP
ARK GUARDS AS
NEEDED
The diameter of the grinding wheels will decrease
with use. Adjust the tools rests and sparks guards
accordingly to maintain a distance of 1/16”from the
wheel.
6. DO NOT STAND IN FRONT OF THE BENCH
GRINDER DURING START-UP
To avoid potential injury caused by debris ejected
from a damaged wheel, stand to one side of the
Bench Grinder when starting the unit. While standing
to the side, turn the unit on, wait one minute until the
unit comes up to full speed before grinding.
7. DO NOT OPERATE IN THE VICINITY OF FLAMMABLE MATERIALS
Bench grinders will produce sparks and debris during grinding. Be sure to keep flammable materials
from the immediate vicinity. Be sure to clean the
grinding dust from the back of the Bench Grinder
frequently.
8. DO NOT FORCE THE WORKPIECE AGAINST THE
GRINDING WHEEL
Excessive force especially to a cold grinding wheel
may damage the wheel and create a dangerous
situation. Apply the workpiece against the wheel
slowly and use firm, steady even pressure. Do not
grind against the sides of the grinding wheel and do
not apply coolant direct to the grinding wheel.
9. KEEP ALL WHEEL GUARDS IN PLACE
Do not use the bench grinder with the wheel guards
removed.
10. KEEP THE TOOL RESTS FIRMLY TIGHTENED
Inspect and re-tighten tools rests before each use.
11. USE THE SUPPLIED WHEEL DRESSER
Always use the supplied wheel dresser to resurface
the face of the grinding wheel.
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric current and reduces the risk of electric shock. This
tool is equipped with an electric cord that has an
equipment-grounding conductor and a grounding
plug. The plug MUST be plugged into a matching
receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment-grounding
conductor can result in risk of electric shock. The conductor with green insulation (with or without yellow
stripes) is the equipment-grounding conductor. If
repair or replacement of the electric cord or plug is
necessary, DO NOT connect the equipment-grounding
conductor to a live terminal.
CHECK with a qualified electrician or service person if
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.
USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE
3-PRONG GROUNDING PLUGS AND 3-POLE RECEPTACLES
THAT ACCEPT THE TOOL’S PLUG. REPAIR OR REPLACE
DAMAGED OR WORN CORD IMMEDIATELY.
GUIDELINES FOR EXTENSION CORDS
USE PROPER EXTENSION CORD.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line
voltage, resulting in loss of power and cause overheating. The table below shows the correct size to
use depending on cord length and nameplate
ampere rating. If in doubt,use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
BE SURE YOUR EXTENSION CORD IS PROPERLY WIRED
and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it. Protect your extension cords from
sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than # 12 wire and should be protected with a 15 Amp time delay fuse. Before connecting the motor to the power line, make sure the switch is
in the OFF position and the electric current is rated the
same as the current stamped on the motor nameplate.
Running at a lower voltage will damage the motor.
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in Figure .
Figure shows a 3-prong electrical plug
and receptacle that has a grounding conductor. If a
properly grounded receptacle is not available, an
adapter (Figure ) can be used to temporarily connect this plug to a 2-contact grounded receptacle. The
temporary adapter should be used only until a properly grounded receptacle can be installed by a qualified
technician. The adapter (Figure ) has a rigid lug
extending from it that MUST be connected to a permanent earth ground, such as a properly grounded
receptacle box. The Canadian Electrical Code prohibits the use of the adapters.
EELLEECCTTRRIICCAALL RREEQQUUIIRREEMMEENNTTSS
In all cases, make certain the receptacle is properly grounded. If you are not sure, have a qualified electrician check the receptacle.
This tool is for indoor use only. Do not expose to
rain or use in damp locations.
This tool must be grounded while in use to protect
the operator from electrical shock.
