Kickback And Related Warnings - Rupes LH19E Manual De Instrucciones

Just because the accessory can be attached to your power
tool, it does not assure safe operation.
4.The rated speed of the accessory must be at least
equal to the maximum speed marked on the power tool.
Accessories running faster than their rated speed can break
and fly apart.
5.The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately guarded
or controlled.
6.Threaded mounting of accessories must match the polisher
spindle thread. For accessories mounted by flanges, the
arbour hole of the accessory must fit the locating diameter
of the flange. Accessories that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
7.Do not use a damaged accessory. Before each use
inspect the accessory such as backing pad for cracks,
tear or excess wear. If power tool or accessory is dropped,
inspect for damage or install an undamaged accessory.
After inspecting and installing an accessory, position
yourself and bystanders away from the plane of the
rotating accessory and run the power tool at maximum
no-load speed for one minute. Damaged accessories will
normally break apart during this test time.
8.Wear personal protective equipment. Depending on
application, use face shield,safety goggles or safety glasses.
As appropriate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable
of stopping flying debris generated by various operations.
The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
9.Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a broken
accessory may fly away and cause injury beyond immediate
area of operation.
10.Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and shock the operator.
11.Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your hand
or arm may be pulled into the spinning accessory.
12.Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your control.
13.Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.

Additional Specific Safety Instructions for Polishers
• Always use eye protection. All users and bystanders must
wear eye protection that conforms to ANSI Z87.1.
• Clean out your tool often, especially after heavy use. Dust
and grit containing metal particles often accumulate on
interior surfaces and could create an electric shock hazard.
• Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause
permanent injury to fingers, hands and arms. Use gloves to
provide extra cushion, take frequent rest periods and limit daily
time of use.
