The guard must be securely attached to the grinder with all
bolts, nuts and lockwashers in place and torqued to 30 to
40 in. lbs.
The speed rating and warnings are roll stamped on housing
and should be replaced for legibility in the event or damage.
Warning tags and warning labels should be maintained.
Warning tags and warning labels are available from the
manufacturer.
Before mounting a wheel, after all tool repairs, and when-
ever a grinder is issued for use, check the free speed of the
grinder with a tachometer to make certain that the actual
free speed at 90 psig (6.2 bar) does not exceed the rated
free speed stamped on the tool. Grinders in use on the job
must be similarly checked at least once every twenty hours
of operation, or once every week, whichever is more
frequent. Checking free speed after the removal of each
worn wheel and before mounting a new wheel is highly
recommended.
INSPECT THE GRINDING WHEEL!
Check the maximum safe RPM marked on the wheel.
Never use a wheel rated below the actual tool speed.
Inspect the wheel for cracks or chips, water stains, or signs
of abuse or improper storage. Cracked, chipped or faulty
grinding wheels are dangerous and must not be used.
They must be destroyed rather than risk their use by
someone who may not notice that they are damaged.
Causes of abrasive wheel failures have been traced to
such factors as:
• Dropping, bumping, or abuse (careless handling
of the grinder or wheel)
Safety Recommendations
• Improper mounting
• Imbalance
• Improper shipment or storage
• Exposure to water, solvents, high humidity,
freezing and extreme temperatures
• Mismatched speed ratings
• Age
Abrasive wheels known to have been subjected to any
of the above conditions can burst violently. Never use
an abrasive wheel known to have been subjected to
any of the above conditions.
CHECK FLANGE
On Type 1 wheel
grinders, the driv-
ing flanges must be
the relieved-type,
free of nicks and
burrs or other flaws
that might create
stress concentra-
tions on the grind-
ing wheel.
Spindles should be
checked for damage or abuse. Blotters must be used and
be at least as large in diameter as the flanges. Diameters
of both driving flange and outer flange must be identical and
both must measure at least one-third the diameter of the
grinding wheel mounted between them. Both flanges must
be properly relieved as per ANSI Safety Code B7.1 and
ANSI B186.1. (See page 6)
Select Type 1 wheels with proper hole size and speed
rating. Never adapt wheels with an oversize hole to fit the
spindle.
ABRASIVE WHEEL MOUNTING & BEGINNING GRIND-
ING OPERATION
The spindle end nut should be tightened firmly against the
outer flange of Type 1 wheels to assure the necessary
friction against the blotter faces to drive the wheel.
Overtightening can cause wheel
breakage.
Type 1 Wheel breakage can also occur if:
• Outer flange is left off
• Outer flange is reversed
• A washer is used in place of proper flange
• Outer flange and driving flange are of unequal
diameters
• No wheel blotters are used

CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
WARNING!
Impact resistant eye protection
must be worn while operating
or working near this tool.
Read Operating Instructions carefully. Follow
the Safety Recommendations for your safety
and the safety of others.
Hearing protection is recommended in high noise
areas (above 85 dBA). Close proximity of other
tools, reflective surfaces, process noises, and
resonant structures can substantially contribute
to the sound level experienced by the user.
WARNING
!
Repetitive work motions and/or vibration
can cause injury to hands and arms.
Use minimum hand grip force consistent with
proper control and safe operation.
Keep body and hands warm and dry.
Avoid anything that inhibits blood circulation.
Avoid continuous vibration exposure.
Keep wrists straight.
Avoid repeated bending of wrists and hands.
Do not remove this tag until
the operator of this tool has
read these safety precautions.
