SAFETY

1.1. ELECTRICALSAFETY.

• 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.

1.2. GENERAL SAFETY

• WARNING! Disconnect the grinder from the mains power, and ensure the grinding 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.

• 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.

• 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.

• ARNING! 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 wheels must be replaced when the 2mm gap above can no longer 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 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.

• Remove ill fitting clothing. Remove ties, watches, rings and other loose jewellery and contain and/or tie back long hair.

• Keep children and unauthorised persons away from the working area.

• DO NOT use the grinder for a task it is not designed to perform.

• WARNING! DO NOT grind any materials containing asbestos.

• DO NOT switch on the grinder whilst the wheel is in contact with the workpiece.

• DO NOT get the grinder wet or use in damp or wet locations or areas where there is condensation.

• DO NOT use grinder where there are flammable liquids, solids or gases, e.g. paint solvents and including waste wiping or cleaning rags etc.

• DO NOT touch the workpiece close to the ground surface as it will be very hot. Allow to cool. The workpiece may also be very sharp.

• DO NOT operate the grinder when you are tired, under the influence of alcohol, drugs or intoxicating medication.

• DO NOT leave the grinder operating unattended.

• When not in use switch off the grinder, disconnect from the mains power supply and clean the machine and working area.

GRINDING WHEELS

5.1. MANDATORY SAFETY INSTRUCTIONS (The following instructions must be observed together with those in Section 1).
▲ DANGER! Use of a damaged wheel (wheel) is dangerous and may cause damage and/or personal injury.

• WARNING! Ensure grinder is unplugged from mains supply before attempting to change grinding wheel (wheel). Only persons qualified
  under the “Abrasive Wheels Regulations” and holding a current grinding wheel certificate are authorised to change and dress grinding wheels (wheels).

• Grinding wheels used with this machine must be of an adequate speed rating and suitable for the material to be ground.

• Ensure the maximum speed specification of the wheel is higher than that indicated on the machine data plate.

• 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.

• 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.

• 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.
5.2.1. Remove the eye shield support plate, loosen and pull the tool rest out as far as possible.
5.2.2. Remove the three screws and the corresponding nuts washers and lock washers from the side of the wheel cover and remove.
5.2.3. Hold grinding wheel firmly – protect your hands with a cloth, or wear gloves. Unscrew retaining nut (fig.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.
5.2.4. Remove grinding wheel washer (2), wheel (3), and washer (4) from main spindle (5) see fig.3.
5.2.5. Carefully inspect the new wheel before installing to ensure there are no fissures, chips, or cracks.

5.2.7. Hold wheel steady and secure locking nut. DO NOT over-tighten as this may crack the wheel.
5.2.8. Replace wheel cover, replace eye shield, re-adjust tool rest to not more than 2mm from wheel and tighten securely.

OPERATION
