1. SAFETY
1.1. Electrical Safety
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other
connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A
Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current
Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected
by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey 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 those appliances
and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2.
and use a Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none are loose.
1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply
to be used and that the plug is fitted with the correct fuse - see fuse rating at right.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item
repaired or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is damaged, cut the
cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires have been correctly
connected, that the cable outer insulation extends beyond the cable restraint and that the
restraint is tight.
Double insulated products, which are always marked with this symbol , are fitted with live (brown)
and neutral (blue) wires only. To rewire, connect the wires as indicated above - DO NOT connect
either wire to the earth terminal.
1.1.10. Products which require more than 13Amps are supplied without a plug. In this case you must contact
a qualified electrician to ensure that a suitably rated supply is available. We recommend that you discuss the installation of an
industrial round pin plug and socket with your electrician.
1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance
plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use
of 2.5mm² section cable.
1.2. General Safety
WARNING! Disconnect the lathe from the mains power and ensure that the chuck or face plate is at a complete standstill before attempting
to change accessories, service or perform any maintenance.
Maintain the lathe in good condition (use an authorised service agent).
Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
Locate the lathe in a suitable area. Ensure that the mounting surface is flat and firm. Keep the area clean and tidy and free from unrelated
materials, and ensure that there is adequate lighting.
Keep the lathe clean for best and safest performance.
WARNING! Before each use check that face plate/chuck, cutting tool and tailstock are secure and not worn or damaged. If any part of the
lathe is worn or damaged replace immediately.

WARNING! Keep chuck guard and holding fixings in place, tight and in good working order. The safety micro switch ensures that the lathe
will not operate when the chuck guard is raised. Check regularly for damaged parts.
A chuck guard that is damaged or missing must be repaired or replaced before the lathe is next used.
WARNING! DO NOT over-ride the chuck guard safety micro switch.
Remove adjusting keys and wrenches from the lathe and its vicinity before turning it on.
WARNING! Wear approved safety eye protection and, if oil mist is generated, respiratory protection.
Remove ill fitting clothing. Remove ties, watches, rings and other loose jewellery and contain long hair.
Keep hands and body clear of the workpiece when operating the lathe.
Maintain correct balance and footing. Ensure that the floor is not slippery and wear non-slip shoes.
Keep children and unauthorised persons away from the work area.
WARNING! DO NOT switch on the lathe whilst the cutting tool is in contact with the workpiece. Bring the cutting tool gradually to the
workpiece.
Avoid un-intentional starting of the lathe.
DO NOT use the lathe for a task it is not designed to perform.
DO NOT allow untrained persons to operate the lathe.
DO NOT get the lathe wet or use in damp or wet locations or areas where there is condensation.
WARNING! DO NOT use the lathe where there are flammable liquids, solids or gases such as petrol, paint solvents, waste wiping rags etc.
DO NOT operate the lathe if any parts are missing or damaged as this may cause failure and/or personal injury.
DO NOT lift or remove the chuck guard whilst the lathe is in use.
DO NOT touch the workpiece close to the cut as it will be very hot. Allow to cool.
DO NOT leave the lathe running unattended.
DO NOT operate the lathe when you are tired or under the influence of alcohol, drugs or intoxicating medication.
When not in use switch off the lathe and isolate from the power supply.

It is assumed that the operator has experience of machining practice and these instructions are intended only to describe the features
of the lathe. If you have no experience of machining it is recommended that you undertake training before using this machine.
WARNING! Before operating the lathe ensure that you are wearing approved safety goggles and gloves to protect you from swarf
and metal particles. If using cutting oil or coolant a face mask may be necessary to avoid breathing any vapour generated. Ensure that
all other safety instructions in Section 1 are followed carefully.
6.1. Initial start-up
6.1.1. Check that the forward/reverse switch is in the forward position (fig.1.9) and that the leadscrew
lever (fig.2.A) is on zero.
Note that the forward/reverse switch must only be changed when the lathe is switched off.
6.1.2. Set the automatic feed lever (fig.2.B) to disengaged - turn clockwise.
6.1.3. Confirm that the cross slide is well clear of the chuck and that all keys, spanners etc. are clear of the machine. Move the cross slide along
the lathe bed by turning leadscrew handle (fig.1.5).
6.1.4. Connect the lathe to the mains supply.
6.1.5. Lower the chuck guard.
Note that the lathe will only operate with the chuck guard lowered.
