Another little glitch with this one; another person was using it in my absence and cut the hydraulic hoses from the machine to the front grab, thus losing some hydraulic oil. Anyway, repaired the hoses and put back in some oil. However, the machine is a little slow to get hydraulic function (lifting / tilting) after start-up, it works fine after a minute or so of warm-up, but it also stalls momentarily on occasion. Also, the grab won't open or close without first toggling the little rocker switch in front of the seat, and this also stalls sometimes. Could these problems be because of the mixture of oils used (even though the oil I put back in is perfectly acceptable for the Mustang)? I didn't top it up fully with oil according to the line of sight gauge inside the rear door - should I? Also, what is SOP for the hydraulic rocker switch in front of the seat - switched towards the rear with the amber light lit or towards the front, in which case an auxiliary (?) seems to be activated ? I need to toggle this switch to get the grab working, whereas I didn't before. Many TIA, Mike.
