W A R N I N G : When using electric tools basic
safety precautions should always be followed to
reduce the risk of fire, electric shock and personal
injury including the following.
Read all these instructions before attempting to
operate this product and save these instructions.
The declared vibration total value has been measured in accordance with a
standard test method and may be used for comparing one tool with another.
The declared vibration total value may also be used in a preliminary assessment
of exposure.WARNING: The vibration emission during actual use of the power
tool can differ from the declared total value depending on the ways in which the
tool is used. The need to identify safety measures and to protect the operator are
based on an estimation of exposure in the actual conditions of use (taking account
of all parts of the operating cycle, such as the times the tool is switched off, when it
is running idle, in addition to trigger time).
Load factor:
A load factor of S2 30 min(temporary duty)means that you may operate the
motor continuously at its nominal power level (250W) for no longer than the
time stipulated on the specifications label (30minutes ON period). If you fail to
observe this time limit the motor will overheat. During the OFF period the motor
will cool again to its starting temperature.

3. Inspect the product before each use for worn and damaged parts. Do not operate
it if you find broken and worn parts.
NOTE: Do not use chemical, alkaline, abrasive or other
aggressive detergents or disinfectants to clean this
product as they might be harmful to its surfaces.
WARNING! Always switch the product off, disconnect it
from power supply and let the product cool down before
performing inspection, maintenance and cleaning work!
WARNING! Only perform repairs and maintenance
work according to these instructions! All further works
must be performed by a qualified specialist!
1. After switching the grinder on, allow it to reach full speed before performing
grinding operation.
2. The eye shields are able to be adjusted and should be positioned to allow the
operator a clear view of the work through the shields.
3. The appropriate adjustments of the tools rests will provide the correct working
angle for efficient grinding. As the diameter of the grinding wheel is subject to
wear. It will be necessary to re-adjust the edge of the grinding wheel.
Fix the grinder to horizontal, stable surface before using. Positing the grinder towards
the front edge of the bench will facilitate the handing of long tools. If possible, leave
space to the left hand side of the machine for easy access to the wet wheel. An
alternative method is to secure the grinder to a sheet of plywood which can then be
clammed to a bench or table to present the grinder in the most convenient position.
Before using the dry wheel ensures that the spark guard (behind the eye shield) is
positioned as close to the surface of the wheel as possible and that the eye shield is
in a position to prevent sparks flying up. It is a sensible precaution to wear safety
spectacles as well when operating a grinding machine.
The dry wheel can be used for grinding profiles or virtually any cutting tool; plane
irons, chisel, gouges, turning tools, drill bits, etc. The aluminum oxide will cut cleanly
and without undue heating of the tip of the tool. However care should be taken not to
grind a tool too hard or for too long in case over-heating occurs.
To renew or change the grinding wheels, follow these series of steps:
1. Switch off the unit and disconnected from the mains supply.
2. Remove the fixing screws(1) on the outside cover(2) and then pull out the
outside cover(2).
3. Remove the nut (3) from the spindle (5) using spanner supplied. The nut on the
right spindle has a right thread; the nut on the left spindle has a left thread.
4. Take out the outer flange (4) from the spindle (5).
5. Place the new wheel onto the spindle. once secured rotate the grinding wheel by
hand to confirm that the wheel moves freely and doesn't contact any surfaces
6. Reassemble the flange, nut, and outside cover.
7. Switch on the machine and let the wheel run with no load for one minute to
check for cracks.

The following information is a guide only on the different types of grinding wheels
and their uses.
TYPES OF ABRASIVE GRAIN
Grinding wheels are made of four main types of abrasive grain: aluminum oxide,
silicon carbide, CBN (cubic boron nitride) and diamond. In the home workshop you
will probably only use wheels of aluminum oxide or silicon carbide. Both types are
available from your tool stockiest. Grain size is separated into four main categories:
course, medium, fine and very fine. Table 1 shows the breakdown of grain size in
each category. For most work a medium or fine wheel is recommended.

14 60 80 180
16 90 220

24 120

TYPES OF BOND
There are five main kinds of bonding agents namely, ceramic (vitrified), phonetic
resin, rubber, shellac and metal. The abrasive can be bonded with its particles close
together or with spaces between each grain particle. Bond material creates a link
between each grain. The spaces between the grains will determine how dense the
wheel is, large spaces will give an open wheel and smaller spaces will give a close
or dense wheel.
The structure is measured on a scale of 0-14 with 0 being very close and 14 being
very open with wide spacing between the grains.
WHEEL HARDNESS OR GRADE
Grade or hardness is the strength of bonding between the abrasive grains. Wheel
hardness is graded alphabetically, in increasing order of hardness; letters A through
D represent very soft wheels, and letters V through Z represent very hard ones.
Letter K in the illustration below represents a soft to medium wheel.

The number shown in the above illustration is an example of a grinding wheel
description. 9A means that the abrasive is aluminum oxide46 means that the
grain size is medium, K means that the wheel is soft, 5 means that the wheel
is dense, V stands for vitrified bonding and 22 is the manufacturer’s symbol.
Wheels supplied with bench grinders are generally “N” on the hardness scale,
which is considered hard. Do not try to sharpen carbide tools, knives, scissors
or high-speed tools (router bits, wood turning tools) with this hard wheel. A
tandard wheel will not cut carbide. If you try, you will only create heat and glaze
over the wheel. Hard wheels will burn router bits and other high-speed tools.
Overheating the tools will destroy their hardness and render them ussels.
Soft wheels give themselves up while grinding. When grinding, only a small
amount of material is removed, and the wheel releases grains a little at a time,
presenting new cutting edges. This releasing activity helps to keep the tool from
heating up and gives a finer grinding result.
