INSTRUCTIONS FOR:

150mm BENCH GRINDER

1. SAFETY INSTRUCTIONS

1.1. ELECTRICAL SAFETY.

! WARNING! It is the responsibility of the user to read, understand and comply with the following:

You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs and

all electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety

devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD

(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with portable products that are plugged

into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician. You may obtain a Residual Current Device by

contacting your dealer. You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by

a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance

and the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.

1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power

supply. See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply, leads and plugs for wear and damage and all electrical connections

especially power connections, to ensure that none is loose.

1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply

to be used and check that plugs are fitted with the correct capacity fuse. A 13 amp plug may require

a fuse smaller than 13 amps for certain products (subject to 1.1.10. below) see fuse rating at right.

1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.

1.1.8. DO NOT pull power plugs from sockets by the power cable.

1.1.9. DO NOT use worn or damaged leads, plugs or connections. Immediately replace or have repaired by

a qualified electrician. A U.K. 3 pin plug with ASTA/BS approval is fitted. In case of damage, cut off

and fit a new plug according to the following instructions (discard old plug safely).

(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.

a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.

b) Connect the BROWN live wire to live terminal ‘L’.

c) Connect the BLUE neutral wire to the neutral terminal ‘N’.

After wiring, check there are no bare wires, that all wires have been correctly connected, that the outer cable insulation

extends beyond the cable restraint and that the restraint is tight.

Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with

this symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or blue to the earth terminal.

1.1.10. Some products require more than a 13 amp electrical supply. In such a case, NO plug will be fitted. You must contact a qualified electrician

to ensure a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug and socket with your electrician.

1.1.11. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD

fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores of the cable

is important. We suggest 1.5mm2section cable as a minimum, but to be absolutely sure that the capacity of the cable reel is suitable

for this product and for others that may be used in the other output sockets, we recommend the use of 2.5mm2section cable.

4. GRINDING WHEELS

4.1. 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).

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 4.2. 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.

4.2. Wheel Changing Procedure. !WARNING! Unplug grinder from the mains power supply before changing wheel.

4.2.1. Remove the eye shield support plate, loosen and pull the tool rest out as far as possible.

4.2.2. Remove the three screws and the corresponding nuts washers and lock washers from the side of the wheel cover and remove.

4.2.3. 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.

4.2.4. Remove grinding wheel washer (fig.3.2), blotter (3), wheel (4), 2nd blotter (5) and washer (6) from main spindle (7).

4.2.5. Carefully inspect the new wheel before installing to ensure there are no fissures, chips, or cracks.

!WARNING! DO NOT USE A DAMAGED WHEEL.

4.2.6. Inspect the blotters - if they are damaged, replace them. The grinder must never be used

without wheel blotters. If none is available when needed, cut the same shape from a piece

of suitable cardboard, for temporary use only.

4.2.7. Install the new wheel by reversing steps above. Ensure washers (2 & 6) are installed

correctly with the concave side against the blotter.

4.2.8. Hold wheel steady and secure locking nut. DO NOT over-tighten as this may crack the wheel.

4.2.9. Replace wheel cover, replace eye shield, re-adjust tool rest to not more than 2mm from wheel and

tighten securely.

5.1. Pre-use Inspection.

!WARNING! INSPECT THE GRINDER BEFORE USE. ENSURE THE GRINDER IS UNPLUGGED FROM THE MAINS POWER

BEFORE COMMENCING THE INSPECTION.

5.1.1. Check the tool rests are securely fixed and are not more than 2mm from the grinding wheels.

5.1.2. Check that eye shields are in good condition, secure and that you can see through them clearly.

5.1.3. Turn the grinding wheels by hand and check for any damage. Check they do not touch the tool rests and are correctly aligned.

If any of the above checks fail, replace, repair, or adjust as necessary before starting the grinder.

5.2. Wheel Use.

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

materials.

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 certificate may install wheels. See Section 4.

5.3. Using the Grinder.

!WARNING! Before commencing work, ensure you read, understand and apply the Section 1 Safety Instructions.

5.3.1. Plug grinder into the mains power supply.

5.3.2. Adjust the eyeshield to give maximum protection.

5.3.3. Switch on the grinder and bring the workpiece slowly into contact with the rotating wheel.

5.3.4. When the task is complete unplug the grinder from the mains power supply and clean the machine ready for next use.

6. MAINTENANCE

!WARNING! Ensure the grinder is unplugged from the mains power supply before performing any maintenance or service.

6.1. As the grinding wheels wear, adjust the positions of the tool rests. Each rest must be set not more than 2mm from the grinding surface.

6.2. Regularly remove the grinding wheel covers and clean out any dust and dirt.

6.3. The machine motor and bearings are sealed units and require no regular maintenance. Should you require assistance, contact your

local service agent.
