Assemble hydraulic check to mounting bracket and assemble mounting bracket to tool using washers (Y14-8) and cap screws

Measure distance from tap point to work piece - distance “Y”. Distance “X”between hydraulic check plunger and trip bracket must be less than distance “Y”to prevent damage to tap point when it approaches the work piece.

Loosenthe cap screws (Y154-48) and position hydraulic check to obtain correct setting for distance “X”.

Tighten cap screws (Y154-48) securely before operating unit, Increase the air flow thru the FeedControl Valve marked “F”by

EMERGENCYRETRACT- depressthe emergency button momentarily.Thissignal to the unit will shift the built-in pressure operated valve, commandingthe unit to retract immediately to the initial position whereupon the unit will stop.

NOTE:MANUALSTARTand EMERGENCYRETRACTbuttons on the tool are fully operational even when remote control is used, The manually operated buttons can be used when set-up IS required.

Shown below is the some system in schematic form.
