change accessories, service or perform any maintenance.
8 DO NOT use a damaged accessory. Before each use, inspect the accessory such as abrasive wheels for chips and cracks.
8 DO NOT operate the grinder if any parts are damaged or missing as this may cause failure and/or personal injury.
▲ DANGER! DO NOT use a damaged wheel as it is dangerous and may cause damage and/or serious personal injury.
WARNING! Only persons qualified under the “Abrasive Wheels Regulations” and holding a current grinding wheel certificate are to change or
dress grinding wheels. Unplug grinder from mains power and refer to Section “Grinding Wheels” below for details.
9 After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run
the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
9 The rated speed of the accessory must be at least equal to the maximum speed marked on the grinder. Accessories running faster
than their rated speed can break and y apart.
9 Never grind on the sides of a grinding wheel. Grinding on the side can cause the wheel to break and y apart.
9 Only use accessories with a diameter and maximum thickness specied in the Specication section of this manual.
9 Bench grinders must always be stable and secure e.g. xed to a bench or the like.
9 Grinding wheels must be correctly mounted and free of defects before use (ring tested).
9 Spark arrestors and work rests must be adjusted frequently so as to compensate for the wear of the wheel.
WARNING! Keep all guards and holding screws in place, tight and in good working order. Check regularly for damaged parts.
A guard or any other part that is damaged should be repaired or replaced before tool is next used. The eye shields are a mandatory
fitting when grinder is used in premises covered by the Health & Safety at Work Act.
9 Distance between the spark arrestor/work rest and the wheel must be kept as small as possible and in any case no greater than 2mm.
9 Worn wheels must be replaced when the 2mm gap above can no longer able to be maintained.
9 For tools with two spindles: always use the tool with accessories on both spindles in order to limit the risk of contact with the rotating
spindle.
9 Always use the guard, work rest, transparent screen and spark arrestor as required for the accessory(ies).
9 Damaged or deeply grooved wheels must be replaced.
9 Always adjust the work rest so that the angle between the work rest and the tangent of the accessory is always greater than 85°.
9 Grinding wheels must always be handled and stored in the correct manner.
9 Maintain the grinder in good condition and check moving parts alignment regularly.
9 Replace or repair damaged parts. Use recommended parts only. Non-authorised parts may be dangerous and will invalidate the warranty.

5.1. MANDATORY SAFETY INSTRUCTIONS. (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 qualified
under the “Abrasive Wheels Regulations” and holding a current grinding wheel certificate are authorised to change and dress grinding
wheels (stones).
9 Grinding wheels used with this machine must be of an adequate speed rating and suitable for the material to be ground.
9 Ensure the maximum speed specification of the wheel is higher than that indicated on the machine data plate.
9 Check that grinding wheels are secure and that wheels are not worn or damaged, that there are no fissures 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 flanges
for deformation, burrs or chips. Damaged flanges 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.
9 Install 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.

6. OPERATING
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 fixed 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.

The grinder is supplied with two aluminium oxide wheels, one coarse and one fine. Fine is preferred for hard materials and coarse for
soft materials.
