up into its respective sub cavity 38 the squid acts as a vent releasing the cleaner from the combustion chamber while at the same time safely containing it this prevents any damage to the piston or rods that could be caused by hydrolocking the engine on the down stroke of piston 66 however the fluid will be drawn back down out of the sub cavity 38 through the conduit 16 into adaptor 18 and back into chamber 64 the cleaner moves in and out of the chamber 64 consonant with piston 66 position during bumping the bumping process works cleaner into the compression rings 72 thoroughly this causes the carbon deposits on rings 72 to dissolve into the cleaner the engine 20 should be bumped several times for optimal results the user should ideally wait 15 minutes between each bumping in order to allow the cleaner to gradually dissolve the carbon deposits on the compression rings 72 after the bumping process has been repeated every 15 minutes for the desired amount of time usually 2 hours it is time to blow out the cleaner the blowing out process is accomplished by attaching a pressurized air source 28 onto snap on connector 26 engine 20 should then be turned over continuously for 30 to 60 seconds while user observes the translucent tubes 52 for the presence of cleaner the pressurized air from the hose 28 forces the cleaner from the sub cavities 38 down through conduits 16 through adaptors 18 into combustion chambers 64 and then out the exhaust valves 68 of the engine 20 and then out the vehicle 39 s exhaust system once tubes 52 are clear of cleaner the user should continue.
