Health & Safety

 

As  with all machinery there are certain hazards involved with the operation and use of the lathe. Using 
the machine with respect and caution will considerably lessen the possibility of person injury. However, if 
normal safety precautions are overlooked or ignored, personal injury to the operator may result. 
This machine was designed for certain applications only. We strongly recommend that the machine is not 
modified, and / or used for any application other than which it was designed.

 If you have any questions 

relative to its application do not use the machine, until you have first been in contact with Chester 
UK.

 

The  lathe  may  not  arrive  with  a  power  socket  or  plug.  In  the  event  of  this  happening,  please  inform 
Chester UK on Tel: (01244) 531 631.

 

Safety rules for all tools 

User 

1.  Wear correct apparel

 

No  loose  clothing,  gloves, rings,  bracelets  or  other  jewellery  to get  caught  in  moving  parts.  Non­ 
slip footwear is recommended. Wear protective hair covering to contain long hair.

 

2.  Always wear eye protection

 

Refer  to  ANSLZ87.1  standard  for  appropriate  recommendations.  Also  use  face  and  /  or  a  dust 
mask if the cutting operation is dusty.

 

3.  Don’t overreach

 

Keep a proper footing and balance at all times.

 

4.  Never stand on a tool

 

Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted.

 

5.  Never leave the tool running unattended 

Turn power off.

 Leave tool until it comes to a complete stop.

 

6.  Drugs, alcohol and medication

 

Do not operate the tool while under the influence of drugs, alcohol or any medication.

 

7.  Make sure the tool is disconnected from the power supply

 

While motor is being mounted, connected or reconnected.

 

8.  Always

 

Keep hands and fingers away from any moving parts.

 

9.  Stop

 

The machine before moving chips.

 

10. Shut­off

 

Power and clean the lathe and work area before leaving the machine.

 

Use of the machine 

1. 

Remove adjusting keys and wrenches

 

Form  a  habit  of  checking  to  see  that  keys  and  adjusting  wrenches  are  removed  from  the  tool 
before turning it ‘on’.

 

2. 

Don’t force the tool

 

It will do the job better and be safer at the rate for which it was designed.

 

3. 

Use the right tool

 

Don’t force the tool or attachment to do a job for which it was not designed.

 

4. 

Secure work

 

Use clamps or a vice to hold work when practical. It’s safer than using your hands, and frees both 
to operate the machine.
