I am in desperate need of a service manual for my Komatsu PC 112-u excavator. Free, reasonable cost or pay for a photocopy even
This is used for home use only and the rams on the digger arm started getting very slow when operating and now stopped working. the sideshift ram, blade ram, rotation and drive motors all work well.

Unfortunately, the best advice I can give is to go to My Komatsu.
I don't know what they have or don't have for manuals.

Do a Google search for a manual. There are many sites where you can download and even print your manual for free.
Thanks mate, done many searches, joined 'Manuals Global' six months ago and they are still searching.
