ward with head cylinder assy removed. Hydraulic oil will eject forcibly from handle assy.
The disassembly and re-assembly procedure can be accomplished by utilizing the following instructions and drawings.
Use extreme care during disassembly and re-assembly not to mar or nick any smooth surface that comes in contact
with seals. Before installing seals, always apply a good lubricant, such as Lubriplate®, to the surfaces. It is recom-
mended that tool kit (GB740TK) be used to facilitate overhaul. A complete overhaul can be achieved by the use of Ser-
vice Kit (703043) which contains a complete set of o'rings, back-up rings, screws, washers and gasket.
