Hi, Any ideas on AL-35 (HYD. MOTOR OVERLOAD) My KIA KT15 lathe (Yasnac LX3 control) was running great till hyd. motor pump started groaning alittle when cycling the chuck...... then up pops the AL-35 alarm..... probably shelled the pump? Why? Lack of oil? No. Lack of cooling??? Hyd. motor has cooling fan which pulls air over an oil cooler in the back part of the motor.... Is the motor thermally protected?
