OVERHAUL

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 recommended that tool kit (GB740TK) be used to

facilitate overhaul. A complete overhaul can be achieved by the use of Service Kit 740002 which contains a complete set of o'rings,

back-up rings, screws, washers and gasket. It is recommended that this service kit be kept available for spare parts.

WARNING:

DEPRESS TRIGGER AND DISCONNECT FROM AIR WITH HEAD PISTON IN THE REAR POSITION BEFORE

OVERHAUL. SEVERE PERSONAL INJURY MAY OCCUR IF AIR HOSE IS NOT DISCONNECTED.

WHEN FORCING PISTON ROD ASSEMBLY DOWNWARD WITH HEAD CYLINDER ASSEMBLY REMOVED,

HYDRAULIC FLUID WILL EJECT FORCIBLY FROM HANDLE.
