35+ year old Mares Shortie Competition SG, 12.75 barrel length

I am returning to spear fishing after a long hiatus. I am looking for a manual for my Mares Shortie Competition spear gun. It's about 35 years old but still has the original air charge and bench functions just fine.

Does anyone have a source for the owners/service manual for this spear gun?

Thanks,

Mudbug

You can get the cyrano manuals on the mares Italy website. (They’re in English.). Give that a try?

It's also known as the Minimini Sten.

Users guide is here: Mares Pneumatic Guns User guide | Manualzz

You can look through the Mares Service Manuals here: Mares Regulator Service Manuals and Info . Start with the earliest ones.

I don't think I have one for your exact gun, but maybe you can get what you need from the service manuals for other models.

I thank all of you...

That is a Mares "Competition Line" gun, otherwise known as the Sten 87. It marked the change to the more angular handle and muzzle that departed from the grease gun look of the previous model. The instructions are the same for all the models except the parts change with the new plastic mouldings. This reference shows the diagram for the "Competition Line" guns at post #20. The next change was the Sten 2001 and that model continues to this day.

Thanks Popgun....is there an online service center you could recommend?

No, but you can do the work yourself. There is a gun dismantling thread here Pneumatic dismantling: how to get inside

The guns are not difficult to pull apart provided that you take a methodical approach and work on a clean worktable or bench as you don't want dust and dirt getting on the oily parts. Pneumatic spearguns are oleo-pneumatic as they need internal lubrication with oil such as motorcycle suspension fork oil.
