-4- H4378/H4379 Slimline Bench Grinder
Additional Safety Instructions For Grinders
1. ALWAYS WEAR EYE PROTECTION!
2. MAKE SURE GRINDER IS SECURED
FIRMLY TO A BENCH OR STAND
BEFORE USE. Any “wobbles” must be
corrected by shimming or blocking before
operation.
3. BEFORE MOUNTING A NEW WHEEL,
BE SURE WHEEL RPM IS RATED AT
AN EQUAL OR HIGHER RPM THAN
THE GRINDER.
4. DO NOT GRIND ON THE SIDES OF
THE GRINDING WHEELS, unless they
are special wheels designed specifically
for this purpose.
5. ONLY USE FLANGES THAT ARE
INCLUDED WITH THE GRINDER.
6. WEAR AN APPROVED DUST MASK
OR RESPIRATOR. Grinding operations
produce dust.
7. REPLACE A CRACKED WHEEL IMME-
DIATELY. DO NOT use a grinding wheel
that has cracks or flaws. Before using,
inspect each wheel. Handle wheels care-
fully to avoid bumping or dropping.
8. DO NOT stand directly in front of grinding
wheels when turning machine on.
9. PERFORM a “ring test” (see page 12) on
grinding wheels to ensure that they are
safe for use. Always inspect grinding
wheels before operation.
10. HOLD THE WORKPIECE FIRMLY
WHILE GRINDING.
11. DO NOT allow your hands to come into
contact with grinding wheels during oper-
ation. Abrasive accessories have the
ability to remove a lot of material, includ-
ing skin, very quickly. However, do not
wear gloves while grinding, they may get
caught in the grinding wheel.
12. KEEP TOOL REST AS CLOSE AS
POSSIBLE TO GRINDING WHEEL.
13. NEVER GRIND BY PLACING THE
WORKPIECE ON TOP OF THE
WHEEL. The wheel may kick the work-
piece toward the operator. Always grind
on the downward part of the wheel.

Always consider safety first, as it applies to
your individual working conditions. Use

respect. Failure to follow guidelines could
result in serious personal injury, damage to

To operate this or any power tool safely and
efficiently, become as familiar with it as
possible. The time you invest before you

be time well spent. DO NOT operate this
machine until you are completely familiar
with the contents of this manual, or serious
personal injury may occur.
