Rating Description

Hobby: Suitable for Weekend DIY'ers and woodworking enthusiasts.

Generally lighter weight machines with lower power ratings and smaller tooling capacities. Typically only

ever used by one person for short periods of time or longer periods of time infrequently. Machinery should

be well maintained in a clean, dry environment such as a home workshop, garage or timber shed.

Expected maximum use of 100 hours annually.

Please Note: Using a product in excess of its rating will void the manufacturer’s free warranty.

Spin the wheels by hand to make sure

they are not catching on the tables or

brackets.

Setting Up

Spin the wheels by hand to check they

run true.

If not, turn the grinder on and wait for it

run to full speed.

Wearing gloves, hold the wheel dresser

firmly onto the work table then move

forward lightly onto the grinding wheel,

without creating sparks.

Move sideways over the entire width of

the wheel.

Using The Grinder

To start the grinder, set the On/Off

switch position to: 1

Wait for the motor to reach its

maximum speed of rotation. Only then

should you begin grinding.

To stop the grinder, set the On/Off

switch position to: 0

Be aware the motor will take some

time to come to rest.

CAUTION: Do not touch moving parts.

Exert only moderate pressure on the

workpiece so that it can be machined

at constant speed.

Instead of accelerating your work,

high pressure will cause the drive unit

to slow down and even stop, thus

overloading the motor.

For your own safety, it is essential to

hold small pieces with a pair of locking

pliers.

Place the workpiece onto the

workpiece support and slowly guide

the workpiece towards the grinding

wheel at the desired angle, to the

point where the workpiece and

grinding wheel make contact.

Move the workpiece slightly back and

forth to produce an optimal grinding

result.

This way the grinding wheel will be

evenly worn.

Allow the workpiece to cool down

occasionally.

The machine includes an integral tray

which should be half filled with water.

If the ground edge turns bluish black it

is overheating and should be regularly

dipped into the cooling tray.

The white stone wheel is a material

designed to prevent heat building up

and should be used whenever heat is

an issue.

Maintenance

TO REPLACE THE GREY STONE

Disconnect from the power source.

Using a 10mm spanner remove the

three nuts from the stone guard cover.

Remove the side cover.

nut, remember undo the nut in the

direction of the stones rotation as

indicated by the arrow on the guard

Clean the interior of the stone guard.

Inspect the new stone for cracks and

damage to either the front face or the

edges before fitting.

stone.

CAUTION: Do not overtighten.
