alpha 1M underpinner problem

[colinjack2]

hi, can anyone help me?

i have an alpha iM underpinner. when the foot pedal is pressed half way down, the vertical clamp [pad] is supposed to move down and hold the corner tight. then a further foot push pushes the v nail in. the latter is ok, but not the former, the vertical clamp won't move down at all.

i have had a good look inside it, can't see what the problem is or even how it is supposed to move .

can anyone help? had this problem? does anyone know of anywhere i can get someone to look at it? i live in worcester in the uk

thanks for looking

check the 2 bolts underneath the table, directly below the 2 rods that the clamp head is attached to, these can come loose and in extreme circumstances can shear, any local car machanic can fix this and put you mew bolts in, ask him to lock tight them in and it won't happen again.

that was exactly what had happened, sheared bolts. got it all fixed, after the local garage removed the broken bolts.

many thanks for your help!!!!
