RULES FOR SAFE OPERATION
n USE OUTDOOR EXTENSION CORDS. Use only
extension cords with approved ground connection that
are intended for use outdoors and so marked.
n NEVER reach to pick up a workpiece, a piece of scrap,
or anything else that is in or near the grinding path of the
wheel.
n AVOID AWKWARD OPERATIONS AND HAND POSI-
TIONS where a sudden slip could cause your hand to
move into the wheel. ALWAYS make sure you have good
balance.
n NEVER stand or have any part of your body in line with
the path of the wheel.
n DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
n DO NOT TURN THE MOTOR SWITCH ON AND OFF
RAPIDLY. This could cause the wheel to loosen and could
create a hazard. Should this ever occur, stand clear and
allow the wheel to come to a complete stop. Disconnect
your grinder from the power supply and securely retighten
the wheel nut.
WARNING:
When servicing use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
n USE ONLY FLANGES furnished with this bench
grinder.
n IF ANY PART OF THIS GRINDER IS MISSING or should
break, bend, or fail in any way, or should any electrical
component fail to perform properly, shut off the power
switch, remove the machine plug from the power source
and have damaged, missing, or failed parts replaced be-
fore resuming operation.
n MAKE SURE THE GRINDER IS SECURELY MOUNTED
as described in the operating instructions before con-
necting the tool to a power supply.
n DO NOT OVERTIGHTEN THE WHEEL NUT. Excessive
tightening can cause the wheel to crack during opera-
tion.
n INSPECT GRINDING WHEEL for visible defects. Check
the wheel for fissures and cracks, and test for normal
operation prior to use.
n ADJUST distance between wheel and work rest to main-
tain 1/16 in. or less separation as the diameter of the
wheel decreases with use. The value of separation used
in the marking is to be the separation recommended by
the manufacturer but shall not be more than 1/8 in.
n ALWAYS EASE THE WORKPIECE AGAINST THE
ABRASIVE WHEEL when starting to grind. A harsh
impact can break the wheel. Use light pressure when
starting to grind; too much pressure on a cold wheel can
cause the wheel to crack.
DO NOT EXPOSE
TO RAIN OR USE IN
DAMP LOCATIONS
n RISK OF INJURY DUE TO ACCIDENTAL STARTING.
Do not use in an area where children may be present.
n NEVER START THE GRINDER when the wheel is in
contact with the workpiece.
n SECURE WORK. Always hold workpiece firmly against
the work rest.
n DO NOT USE THE BENCH GRINDER if the flange nut
or clamp nut is missing or if the spindle shaft is bent.
n FREQUENTLY clean grinding dust from beneath grind-
er.
n DO NOT OPERATE THIS TOOL WHILE UNDER
THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY
MEDICATION.
n ALWAYS STAY ALERT. Do not allow familiarity (gained
from frequent use of your grinder) to cause a careless
mistake. ALWAYS REMEMBER that a careless fraction
of a second is sufficient to inflict severe injury.
n STAY ALERT AND EXERCISE CONTROL. Watch what
you are doing and use common sense. Do not operate
tool when you are tired. Do not rush.
n SAVE THESE INSTRUCTIONS. Refer to them frequently
and use them to instruct other users. If you loan someone
this tool, loan them these instructions also.
WARNING:
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals
are:
lead from lead-based paints,
crystalline silica from bricks and cement and other
masonry products, and
arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust
masks that are specially designed to filter out microscopic
particles.
