WORN DURING OPERATION.

WARNING:

DO NOT PULL RIVET IN THE AIR. PERSONAL INJURY FROM FASTENER EJECTING MAY OCCUR

CAUTION:

DO NOT USE BEYOND THE DESIGN INTENT.

WARNING:

DO NOT BEND TOOL IF STUCK ON FASTENER.

CAUTION:

BE SURE THERE IS ADEQUATE CLEARANCE FOR TOOL AND OPERATOR'S HANDS

BEFORE PROCEEDING AS SEVERE PERSONAL INJURY MAY RESULT.

WARNING:

DO NOT PULL PIN UNLESS INSERTED IN SHEET. SEVERE PERSONAL INJURY MAY

RESULT.

CAUTION:

HYDRAULIC POWER UNITS THAT ARE NOT EQUIPPED WITH RELIEF VALVES AND THAT

DELIVER HIGH PRESSURE FOR THE "PULL" AND "RETURN" ARE NOT RECOMMENDED

AND MAY BE DANGEROUS.

WARNING:

BE SURE POWERUNIT IS DISCONNECTED BEFORE CLEANING, OR WHEN REPLACING

WORN OR DAMAGED COMPONENTS. SEVERE PERSONAL INJURY MAY OCCUR IF

POWER SOURCE IS NOT DISCONNECTED.

When the tool is connected to the power supply, depressing the actuator will simultaneously start the pump

and shift the directional valve. Hydraulic oil is then forced up and into the front side of the cylinder head,

causing the piston to move to the rear position. The internal components of the attached nose assembly are

also moving with the piston to start the fastener installation. As the piston nears the end of its stroke, it ex-

poses flats on the unloading valve. These flats relieve the oil pressure and allows the fluid to return to the

reservoir tank. When the fastener installation is completed, the actuator is released causing the directional

valve to shift back to its original position. Hydraulic fluid is then directed to the rear of the piston moving it

and the internal components of the nose assembly forward to their original position.
