DETAILED SAFETY REGULATIONS
Bench grinder safety warnings
a) Do not use a damaged accessory. Before each use, inspect the
accessor such as abrasive wheels for chips and cracks and
wire brushes for loose or cracked wires. After inspecting and
instigating 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.
b) 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.
c) Be aware that wire bristles are thrown by the wire brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the wire brush. The wire bristles can
easily penetrate light clothing and/or skin.
d) Never grind on the sides of a grinding wheel. Grinding on the
side can cause the wheel to break and fly apart.
CAUTION! This device is designed to operate indoors.
The design is assumed to be safe, protection measures and
additional safety systems are used, nevertheless there is
always a small risk of operational injuries.
CONSTRUCTION AND USE
Bench grinder is designed for light-duty works in small workshops
and for individual, amateur activities (tinkering). It is not intended for
professional use. It is perfect for sharpening tools such as drills and
chisels. Grinder is not designed for continuous use and it must not
be used for more than 30 minutes at a time. After operation at full
load for this amount of time, switch off the grinder and wait until it
cooles down to the ambient temperature. You can install wire
brushing wheels provided that such brush can work at rotational
speed equal to 2950 rpm or higher.
Use the power tool according to the manufacturer's
instructions only!

GRINDER INSTALLATION ON A WORKSHOP BENCH
Four rubber cushions (11) help to limit vibrations and sound
transfer. It is recommended to firmly fix the grinder to a workbench
or a stand with the use of two fixing points designed for such
purpose. They are located on the bench grinder base (fixing bolts
are not included) and guarantee safe operation. Hole for bench
fixing (5) is located at each side of the grinder.
FIXING AND ADJUSTING EYE SHIELDS AND SPARK SHIELD
Prior to fixing of supports for eye shields ensure the grinder is
switched off and that its plug is removed from the mains
socket. Prior to every use of the grinder ensure the eye shields
1 and 2 are properly installed. Eye shield must be installed on
appropriate support above each of the grinding wheels.
• Use supplied screws, washers and arms to fix eye shields.
• Adjust height and angle of eye shields so they match operator and
type of work performed.
• Install spark shield (10) to each of the grinding wheel covers (fig.
C).
• Set the spark shield to desired position.
• Turn the grinding wheel by hand to ensure it has no contact with
the spark shield.
• Tighten the screw firmly.
• Repeat the operation for the second spark shield.
Do not tighten screws for plastic plates too hard as it may
cause the plates to crack. Spark shield should be adjusted so
its lower edge is 2 mm from the grinding wheel surface. It is
necessary to correct position of the spark shields from time to
time, to compensate wear of the grinding wheels.
INSTALLATION OF THE WORKRESTS
Prior to fixing of workrests ensure the grinder is switched off
and that its plug is removed from the mains socket.
It is necessary to use workrests (8) with every high speed grinding
wheel to help in grinding tasks. Never use bench grinder without
workrests or with workrests improperly adjusted. There are left and
right workrests supplied. Ensure the correct workrest is installed at
each side.
