WARNING!
This instruction manual should be read before assembling or using your bench grinder.
All instructions should be strictly adhered to so the safety of yourself and others is protected.
Keep this manual handy for future reference.
1. The grinder and all accessories are designed and manufactured to be used only by persons
trained in their proper use and only for their intended purpose. They are not intended for lengthy
continuous usage. i.e. Turn ON, Sharpen Tool, Turn OFF
2. Follow assembly instructions closely and do not plug machine into mains power until all guards
are rmly attached in the correct position (and remain so) and all parts are securely tted.
3. Make sure the grinder is securely clamped or bolted to your workbench or pedestal stand and
that the workbench or stand is securely attached to the oor.
4. Make sure the switch is in the o position before connecting to mains power. Any adjustments or
maintenance should be made with the grinder unplugged from its power source. Ensure any keys
or wrenches are removed.
5. Ensure the machine is electrically grounded. The plug must match the outlet and must never be
modied in any way. Long extension leads should not be used due to voltage drop.
6. Ensure the work area is clean and well lit. Do not use in wet or damp conditions. Keep children
and bystanders away.
7. Eye protection should always be used. Normal optical spectacles are not sucient. Neck ties
should be removed and sleeves rolled up. Long hair and loose clothing should be secured. Do not
wear gloves. Non slip footwear or anti-slip footwear is recommended. Hearing protection should
be used for prolonged use.
8. Never use the grinder if impaired by tiredness, alcohol, drugs or medication.
9. The action of grinding will produce dust and/or particles from both the material being ground
and the grinding wheel or belt. Depending on the product being ground, these particles & dust
may be harmful to your health. Ensure the area is well ventilated and that suitable dust mask or
breathing apparatus is used.
10. Never leave a running grinder unattended. Do not leave the work area until it has come to a
complete stop.
11. Your grinder should only ever be serviced by a qualied repair person. To ensure safety integrity,
we recommend using only genuine LinishallTM replacement parts or accessories.
12. Familiarise yourself with the section about correct use of grinding wheels

The correct use & care of grinding wheels
Always use the correct type of grinding wheel according to the model of grinder and your intended
use. Do not use grinding wheels as a cutting disc.
During normal use, grinding wheels will wear by becoming chipped, worn at the edges, grooved,
out of balance and clogged by foreign material. This can be rectied by use of a wheel dresser. Rest
the cast face of the dresser on the tool rest and bring the wheels into contact with the wheel (whilst
running). Move the dresser backwards & forwards (left and right) across the wheel until a fresh, at,
square face is exposed on the wheel.
Sometimes a wheel may be cracked. Never under any circumstances use a cracked wheel for
grinding as it could ‘explode’causing serious injury to the operator. Wheels can be tested for cracks
with the “Ring Test”. This involves hanging a wheel (removed from the grinder) by a piece of string
passed through its centre hole. The wheel can then be tapped with a piece of scrap wood or similar
and if OK the wheel will “ring”. If there is a defect it will sound as a “thud”. The defect may not be able
to be detected by visual inspection. It is important that a wheel failing the ring test be permanently
discarded.
The LinishallTM grinders are supplied with general purpose grinding wheels. For specialised grinding
applications, such as carbide grinding, please consult your local specialist abrasive distributor.
Always grind by using the outer diameter edge of the grinding wheel. Never grind on the side of the
grinding wheel. This can cause the wheel to shatter.
Do not use excessive force on the grinding wheel. If it is not removing material fast enough, it is
either clogged (requiring cleaning with the wheel dresser as above) or is not coarse enough. Choose
the correct grit (coarseness) for the job.
Always adjust the tool rest as close as possible to the wheel (maximum 3mm gap) and do not
attempt to grind objects that are to small to hold securely. Do not use the workpiece to slow down
the wheel after turning the grinder o.
