Help...Gear Won't Come Up

[skymaster]

howdy: i usually get a couple guys to pull the aircraft carefully on its tail. I run nose gear up and down. be careful not to drop. knock on wood solved most glitch.occacionaly, after take off it needs a couple hand pumps to put some pressure on the switches. especially if its been sitting. just got back from rtc training. ins company is back on the hook.
