Posted: 06/01/2012 18:29:13 Reply | Quote After a years storage I dug my Holman 303H airleg machine out of the back of the shed. Coupling it up to an air hose and opened the valve; nothing - it had siezed. Probably some moisture in it when I put it away. So far I have lubricated it,, reconnected it to the air opened the valve and tapped it with a hide mallet with no result. Next step is probably to douse it in diesel. Does anyone have any ideas how to free it up without stripping it? IP: 81.155.193.48 |

Posted: 11/01/2012 14:17:33 Reply | Quote Have you got it working ? Taking it apart was something I was taught at CSM once along time ago. You might find that having taken it apart and given it a good soak all will be sweetness and light. Also I know some one who will have some spares if required !

Posted: 11/01/2012 16:55:48 Reply | Quote I have some more (if needed ) advice, the rock drill oil that is used when the machines are operated if left turns all the surfaces inside the drill to a kind of varnish as well as assisting in seizure. A good soaking in diesel is recommended to remove all the dried out rock drill oil. A good blast with some air to clean out all the chambers and once put back together should sing like Holmans intended  -- If it can't be grown it has to be mined. IP: 81.137.244.112 |

Posted: 11/01/2012 18:01:50 Reply | Quote On examination the piston had siezed in the bore and the ratchet assembly was also sticking. Fortunately neither problem was terminal, both being easily sorted. As I had a compessor on hire I fired the machine up this morning and it appears to be working. That said I am not 100% certain that I have set the valve assembly up correctly - running the machine dry I am getting a considerable amount of air coming out of the water inlet; is this normal?

Posted: 12/01/2012 10:03:29 Reply | Quote You are quite right it is not normal for air to come out of the water inlet. Have you checked that the water needle is located correctly. I'll have a look later for the 303 manual that I have, or there may be one on this site already. -- If it can't be grown it has to be mined. IP: 81.137.244.112 |
