9 Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
9 Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
Important: Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is tted with the correct fuse.
8 DO NOT pull or carry the appliance by the power cable.
8 DO NOT pull the plug from the socket by the cable.
8 DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or is replaced immediately
by a qualied electrician.
If the cable or plug is damaged during use, switch off the electricity supply and remove from use.
Ensure that repairs are carried out by a qualied electrician.
WARNING! Disconnect the grinder from the mains power, and ensure the wheels are at a standstill before attempting to 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 and wire
brushes for loose or cracked wires.
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 Be aware that wire bristles are thrown by the wire brush even during ordinary operation. Do not overstress the wires by applying
excessive load to the wire brush. The wire bristles can easily penetrate light clothing and/or skin.
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 wheel/s must be replaced when the 2mm gap between the spark arrestor/work rest is 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 and wire 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.
9 Locate grinder in a suitable working area, keep area clean, tidy and free from unrelated materials. Ensure adequate lighting.
9 Before each use check grinding wheels for condition. If worn or damaged replace immediately.
WARNING! Always wear approved eye or face protection when operating the grinder.
9 Use breathing protection in accordance with COSHH regulations if fumes or dust pose a hazard. Wear ear defenders if necessary.
9 Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.

6. OPERATION
6.1. PRE USE INSPECTION
Note: Use the same clearance and alignment information if your model has a wire brush.
WARNING! INSPECT THE GRINDER BEFORE OPERATING THE MACHINE. ENSURE THE GRINDER IS UNPLUGGED FROM THE
MAINS POWER BEFORE COMMENCING THE INSPECTION.
6.1.1. Check the tool rests are securely fixed and set at a maximum of 2mm from the grinding stone.
6.1.2. Check that eye shields are in good condition, are secure and that you can see through them clearly.
6.1.3. Turn the grinding stones by hand and check for any damage. Check they do not touch the tool rests and are correctly aligned.
If any of the above checks fail, replace, repair, or adjust as necessary before starting the grinder.
6.2. STONE USE
Depending on the model, grinders are supplied with one or two aluminous oxide stones. Stones have two grades, fine are preferred for
hard materials and a coarse stones for soft materials. When grinding, should surface of the stone become “loaded” (coated with particles
of the material being ground) it is probably the wrong grade of stone for the job. IMPORTANT REMINDER: Grinding stones MUST Only
be assembled by a person holding a grinding wheel certicate. Section 5.
6.3. USING THE GRINDER
WARNING! Before commencing work, ensure you have read, understood, and apply the section 1. Safety Instructions. Plug grinder into
the mains power supply. Place the eyeshield in its appropriate safety location.
Switch the grinder on, and bring the workpiece slowly into contact with the spinning stone, or wire wheel.
When you have completed your task, unplug the grinder from the mains power supply, and clean the machine ready for next use.
7. MAINTENANCE
WARNING! Ensure the grinder is unplugged from the mains power supply before performing any maintenance or service.
7.1. As the grinding stone wears, adjust the position of the tool rests. The rest must be at a maximum of 2mm from the stone surface.
7.2. Regularly remove the grinding stone covers and clean out any dust and dirt.
7.3. The machine motor and bearing are sealed units and require no regular maintenance. Should you require assistance, contact your local
Sealey service agent.
7.4. For information relating to the handling and maintenance of grinding stones refer to section 5.
