Re: HI and Low Piston Spindle Activated at the same time
Last time that happened here it was because the oil got low in the air-over-oil reservoir.
It is a fussy system and needs to be bleed out of the cylinders carefully if they ever get air in them. If they have air they will bounce during use. i have seen the bounce cause both cylinders to actuate and lock the belt. The spindle was doing 10k at the time. LOUD bang and and 10000sqft shop could hardly see a few feet for the smoke. Fun
I usually MDI S.1 <enter> (wait for actuate), S.2 <enter> (wait for actuate), repeat about 20 times on startup to ensure no air intrusion on every start up.
Bear in mind that my machine can sit for months on end which is detrimental.
