3. Additional Health & Safety for Wet

Stone Sharpeners

Safe Operation

• The wet stone sharpener should be level and stable at all

times.

• The machine should be placed on a suitable workbench.

Depending on the sharpening application, access will be

required to both sides of the grinder, so it is not practical

to fix the machine to the work bench.

• When positioning the machine on the bench, ensure that

there are no objects between the base of the machine

and the bench surface and that all four feet of the

machine make contact with the bench.

2. Familiarise yourself with the machine

• Although the wet stone sharpener runs at relatively

low speed, there are still risks present that can lead to

accidents. Most accidents with this type of machine

involve trapping of fingers or hands between the

exposed sharpening stone or honing wheel and the body

of the machine, or loose clothing being drawn in to the

moving parts. In addition there is the risk of injury from

the sharp edges of the tool.

• The risk of breakage is inherent in every abrasive wheel.

The level of risk is lower with slow speed grinders.

Always handle grinding wheels with extreme care. They

are brittle and the slightest impact can cause fractures

within the stone.

• This machine is designed for the sharpening and honing

of tools, knives, chisels, axes etc made of metal. It should

not be used for any other purpose.

• The machine and particularly the sharpening stone should

be protected from frost. If the water retained within

the stone freezes it can cause the stone to crack. If the

machine is not to be used for long period, empty the

water trough, remove the sharpening stone and store it in

a dry place at temperatures above 5°C.

3. Before switching the machine ‘ON’

• Select the correct jig or fixture for holding the tool to be

sharpened. The manual details all of the jigs available for

the machine and the correct method of using them.

• Take the time to ensure that the jig is set correctly to

achieve the correct sharpening angle for the application

and that the fixings are secure.

• Check that there is sufficient water in the trough to keep

the stone wet whilst sharpening. If the stone is dry, it will

soak up approximately 0.5 litres of water in the first few

minutes

of running.

• Check the condition of the stone. If damaged or cracked

replace the stone immediately.

• Rotate the stone by hand to ensure that it can move

freely without interference from other components.

• Check that the speed control is set to correspond with

the diameter of the sharpening stone mounted on the

machine.

4. Whilst sharpening / honing:

• When the machine is first switched ‘ON’, allow it to run

for up to a minute before applying the work piece.

• Regularly check the water level and top up as necessary.

It may take several minutes before the sharpening stone

is fully saturated and for the water level to remain

constant.

• Certain sharpening applications may need to be carried

out on the side of the stone. It is safe to use the side of

the stone for sharpening providing that the ‘side jig’ is

used for control of the work piece.

• When honing, always have the honing wheel running

away from the edge of the tool. Never attempt to hone

towards the edge as the tool will dig in to the honing

wheel and may be thrown from the machine and the

honing wheel damaged.

5. Maintenance

• Regularly check the condition of the surface of the

sharpening stone. The compound of the stone is quite

soft and grooves can wear in to the face of the stone

quite easily. Dress the stone regularly as described in the

manual. Do not attempt to apply the dressing tool to the

honing wheel.

• If steel is exposed to water for prolonged periods,

rust will form. If rust forms on any of the exposed

components of the machine, they should be cleaned and

lubricated to prevent further damaged.

• The dust from abrasive wheels can be an irritant and a

hazard to your health. As the sharpening stone runs at

slow speed and in water, the risk from air borne dust

whilst sharpening is minimal. However, waste dust will

collect in the water trough and there is a risk of exposure

as the trough dries out. Always use the machine in a well

ventilated area and use additional respiratory protective

equipment when cleaning the machine. When the

machine is dry clean it with a vacuum cleaner to remove

waste material.

6. This machine falls under the scope of the ‘Health & Safety

at Work etc. Act 1974’, and the ‘Provision & Use of Work

Equipment Regulations 1998’. We recommend that you

study and follow

these regulations.

Further guidance can be found in the ‘Safety in the use of

abrasive wheels – publication HSG17’ published by Health

& Safety Executive and available from their website www.
