-LUBE-
The FACTORY Recommended Lube to use throughout your ENTIRE MARKER is Dow55.
It is specifically designed for use with O-rings and is engineered to cause them to swell to assist in maintaining a better seal. However, it is a thicker, more pasty lube and depending on the climate/weather, it's components may have a tendancy separate, allowing the liquid component to be expelled as the Marker is fired, leaving the dryer more pasty component behind to serve as the lube. If you feel you're pretty maintenance savy & you don't mind tearing down your Marker more frequently, this may be the lube for you.
Some of use more experienced Techs prefer to use something a little less Dry & Tacky so we prefer Dow33 on EVERYTHING EXCEPT for the Ram Sleeve O-rings (Stick to Dow55 when at all possible on these to ensure a good seal) due to it's slicker properties. Additionally I have found that using Dow33 increases time between regular maintenance intervals. Another reason you may end up using Dow33 is due to it being more readily available and Dow55 is nearly 3 times the cost.
There are other alternative lubes you may have heard of but if you use any such lube(s), you will do so at your own risk.
As for the Bolt... DO NOT EVER, EVER, EVER, EEEEVER use Lube/Grease to lubricate it. Bolts require OIL. The Factory recommended OIL is Tri-Flow, a Bicycle oil than can readily be found at any reputable Bike Shop. However, ANY regular Paintball Gun OIL will do. From Gold Cup to the cheap oil supplied with most entry level Markers. Just place one good drop on EACH O-ring and smear/work it all around the O-rings to ensure they are completely coated. Not too much though because excess will only act as a Magnet for dirt & debris, causing excessive & premature wear on both the bolt & breech. Additionally you may wish to rub whatever excess oil is left on your fingers all over the rest of the bolt. Careful though as once again too much will be counter productive. The Bolt should be a tad bit on the glossy side when lubed properly.
PROPER O-RING INSTALLATION PROCEDURE
BEFORE installing ANY O-ring, you must first lube the groove generously & then install the O-ring. What this will do is to help the O-ring acheive a better seal and it also serves as a sort of Reservoir of lube that will help keep the O-rings lubed for a longer period of time, extening the life of the O-ring.
PROPER AMOUNT OF LUBE TO USE
The appropriate amount of lube to use is pretty much the same throughout the ENTIRE Marker. EVERY area that requires lubing should have a decent amount of lube on there.
What's a the proper amount?
The Proper amount would be a thin layer of lube, coating the area/part evenly.
RAM
As for the Ram, this is the part that get's lube improperly more frequently. A great deal of people smear Lube ALL OVER the Ram which is counter-productive. All that will do is make the Ram a Magnet for Dirt & Debris. The Proper way to lube the Ram is to lube ONLY the very front around the O-ring (from the very tip to about .25" behind the O-ring) and the rear humped area. The rest of the Ram never makes contact with anything and therefore does NOT require ANY Lubing.
POPPET
This part really doesn't require MUCH lube at all. What you should do is lube the O-ring groove, slide the New O-ring into place and then dip the tip into some Dow33 just until the O-ring is submerged and then slide it out (it usually comes out fairly clean). Then smear it around the end where the O-ring resides and slide it back into the Ram Sleeve. A good tip on this one is to leave a touch extra lube at the very tip so when you slide it back into the Sleeve it coats the inside of the sleeve as well.
REGULATOR PISTONS
These parts require the most amount of lube on your Intimidator. What you want to do is place a good amount of lube in the O-ring groove BEFORE installing the O-ring and then Generously lube the piston (that doesn't mean to Glob it on there), then you should lube the inner walls f the Regulator housing LIGHTLY (I use my pinky for the Torpedo & a cotton swab for the LPR), and if you want to be extra thorough like me, you can smear a thin coat on the regulator springs themselves before sliding them into the reg bodies.
