a shot of worm oil in the injector. pump it a couple times to lube orings. I heat my injector on a giddle. the heat will keep the plastic from cooling too quick. i push plastic in at a slow steady speed and keep plastic under pressure for a count of ten. the amount of pressure depends on the type of clamping u use i use a bench mounted wood vise or viseclamp pliers, the ones with pads on jaws that swivel.
