Hi I have some pressure problems with TK-70 and TK-100 On Tk-100 it's 2500 with small line ? on Tk-70 it's 2000 but once in evry 3 strukes it's getting 3000 please advice how can i adjust pressure Thanks

MAYBE YOU HAVE MAIN CYLINDER PROBLEMS,EVERY SECOND STROCK TRYING TO MAKE UP

ARE YOUR WEAR PARTS IN GOOD ORDER ?

wear parts are a consideration as is the pressure spring adjusment on the cutting ring.  But a rpoper check of max. hydraulic pressures to make sure they are set to factory spec would eliminate the hyd. part of the pump from the equation.

Just for heck of it just make sure that your anti short stroking system is working properly Putz Sure stroke

whare anti short stroking system is located so i could check it

if you look at your electrical schematic there is a third prox switch on one cylinder that is supposed to hold that cylinder up (pressure out every third cycle to prevent short stroking it sounds to me as if its working properly but you will have to check schmatic to make sure
