Eclipse Monthly Tech Bulletin, Aug '09
Since releasing the SL94 marker earlier this year we have seen a small number of customers experience issues with their rammers snapping. Initially we believed that the sole cause of this was due to a fault in the metal that they were machined from, but have now revised that opinion since receive back SL94’s from two separate customers that have broken two rammers apiece.
Both of the markers that came back had their rammer caps screwed into the body loosely; finger tight if you like. When they are insufficiently tightened like this, the rammer and the bolt move further back in the body and this causes the bolt pin to hit the back of the pin slot and consequently “stretches” the head of the rammer; eventually causing it to snap if the marker is repeatedly fired in this condition.
As a result we have revised the design of the rammer so that there is now a greater margin for error with regard to the position of the rammer cap. We have already issued a small quantity of these revised rammers to our beta testers and the initial feedback is that they are working extremely well. We currently do not have any more of the revised rammers available but anticipate that they will be in stock in early September; we will of course let you know as soon as they are available.
Until the revised Rammers are available, we suggest that you inform all SL94 owners to follow these guidelines to ensure that their marker performs at its peak:
- Remove the #011 NBR 70 o-ring on the threads of the Rammer Cap and stretch a #009 NBR 70 o-ring over the rammer cap so that the cap will screw in further.
- Tighten the rammer cap ALL the way in, using the correct sized hex key.
- Lower the LPR output pressure by turning the LPR adjuster screw 1 ½-2 turns in from flush.
By following the above guidelines it will dramatically increase the longevity of the Standard SL94 rammer, and in most cases will prevent any possible failure.

ANYONE who has recieved an aftermarket Zick2 Rammer DOES HAVE the new Rammer design.
ANYONE with an SL94 will have the OLD Rammer design. When Nicky T gets back after his paternity leave we should be instigating a program for ALL SL94 owners to get their Old Zick2 Rammers replaced.
I hope that is clear enough.
