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 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 and drill head 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 and drill head 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 and drill head in a suitable area. ensure that the mounting surface is level and firm. Keep the area clean and tidy and free  

  from unrelated materials, and ensure that there is adequate lighting.

  Keep the lathe and drill head 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 or drill head is worn or damaged replace immediately.
