SAFETY

1.1. ELECTRICAL SAFETY
WARNING! It is the user’s responsibility to check the following:
✔ Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and all electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical products.
Electrical safety information. It is important that the following information is read and understood:
✔ Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
✔ 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 fitted with the correct fuse.
DO NOT pull or carry the appliance by the power cable.
DO NOT pull the plug from the socket by the cable.
DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or is replaced immediately by a qualified 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 qualified 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.
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.
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.
✔ 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.
✔ 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 fly apart.
✔ 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.
✔ Never grind on the sides of a grinding wheel. Grinding on the side can cause the wheel to break and fly apart.
✔ Only use accessories with a diameter and maximum thickness specified in the Specification section of this manual.
✔ Bench grinders must always be stable and secure e.g. fixed to a bench or the like.
✔ Grinding wheels must be correctly mounted and free of defects before use (ring tested).
✔ 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.
✔ 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.
✔ Worn wheel/s must be replaced when the 2mm gap between the spark arrestor/work rest is no longer able to be maintained.
✔ 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.
✔ Always use the guard, work rest, transparent screen and spark arrestor as required for the accessory(ies).
✔ Damaged or deeply grooved wheels must be replaced.
✔ Always adjust the work rest so that the angle between the work rest and the tangent of the accessory is always greater than 85°.
✔ Grinding and wire wheels must always be handled and stored in the correct manner.
✔ Maintain the grinder in good condition and check moving parts alignment regularly.
✔ Replace or repair damaged parts. Use recommended parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
✔ Locate grinder in a suitable working area, keep area clean, tidy and free from unrelated materials. Ensure adequate lighting.
✔ 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.
✔ Use breathing protection in accordance with COSHH regulations if fumes or dust pose a hazard. Wear ear defenders if necessary.
✔ Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.

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.

6.2. 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.
