5.1. MANDATORYSAFETYINSTRUCTIONS. (The following instructions must be observed together with those in Section 1).
▲DANGER! Use of a damaged wheel (stone) is dangerous and may cause damage and/or personal injury.
WARNING! Ensure grinder is unplugged from mains supply before attempting to change grinding wheel (stone). Only persons qualied
under the “Abrasive Wheels Regulations” and holding a current grinding wheel certicate are authorised to change and dress grinding
wheels (stones).
9Grinding wheels used with this machine must be of an adequate speed rating and suitable for the material to be ground.
9Ensure the maximum speed specication of the wheel is higher than that indicated on the machine data plate.
9Check that grinding wheels are secure and that wheels are not worn or damaged, that there are no ssures or cracks. If damaged
replace immediately.
9 Ensure replacement wheel is not damaged in any way such as cracks, deformations or splinters etc. Also check the mounting anges
for deformation, burrs or chips. Damaged anges must not be used as they may produce high stresses in the wheel causing it to
break. DO NOT over tighten a wheel. Never tamper with a wheel in order to adapt it to a different size shaft.

9Install a new wheel as in 5.2. Once mounted on the grinder test the wheel before use by facing the grinder in a safe direction (point it
away from yourself, others and vulnerable items) and run for a short time. Dress the wheel if necessary.
5.2. Wheel Changing Procedure.
WARNING! Unplug grinder from the mains power supply before changing wheel.
5.2.1. Loosen the three screws and turn the wheel cover anticlockwise and remove.
5.2.2. Hold grinding wheel rmly - protect your hands with a cloth, or wear gloves. Unscrew retaining nut (g.3.1).
Note: The nut on the right side of the grinder has standard right-hand thread (undo anti-clockwise). The left side nut has a left-hand
thread and must be loosened by turning clockwise. It may be necessary to strike the wrench sharply in the loosening direction, with a
soft-faced hammer, to loosen the nut.
5.2.3. Remove grinding wheel washer (g.3.2), blotter (3), wheel (4), 2nd blotter (5) and washer (6) from main spindle (7).
5.2.4. Carefully inspect the new wheel before installing to ensure there are no ssures, chips, or cracks.
WARNING! DO NOT USE A DAMAGED WHEEL.
5.2.5. Inspect the blotters - if they are damaged, replace them. The grinder must never be used without genuine wheel blotters.
5.2.6. Install the new wheel by reversing steps above. Ensure washers (2 & 6) are installed correctly with the concave side against the
blotter.
5.2.7. Hold wheel steady and secure locking nut. DO NOT over-tighten as this may crack the wheel.

6. OPERATION
6.1. Pre-use Inspection.
WARNING! INSPECT THE GRINDER BEFORE USE. ENSURE THE GRINDER IS UNPLUGGED FROM THE MAINS POWER
BEFORE COMMENCING THE INSPECTION.
6.1.1. Check the tool rests are securely xed and are not more than 2mm from the grinding wheels.
6.1.2. Check that eye shields are in good condition, secure and that you can see through them clearly.
6.1.3. Turn the grinding wheels by hand and check for any damage. Check they do not touch the tool rests and are correctly aligned.
6.1.4. If any of the above checks fail, replace, repair, or adjust as necessary before starting the grinder.
6.2. Wheel Use.
6.2.1. The grinder is supplied with two aluminium oxide wheels, one course and one ne. Fine is preferred for hard materials and coarse for
soft materials.
6.2.2. If the surface of the wheel becomes “loaded” (coated with particles of the material being ground) it is probably the wrong grade for the
job. Important reminder: Only a person holding a grinding wheel certicate may install wheels. See Section 5.
6.3. Using the Grinder.
WARNING! Before commencing work, ensure you read, understand and apply the Section 1 Safety Instructions.

6.3.5. Lockable Switch Refer to g.4
6.3.6. The black centre section of the on/off switch pulls out to prevent unauthorised use.
6.3.7. Overload Protection Fuse Refer to g.5.
