WARNING:
PROPER PULL AND RETURN PRESSURES ARE IMPORTANT FOR PROPER FUNCTION OF INSTALLATION TOOLS. SEVERE
PERSONAL INJURY OR DAMAGE TO EQUIPMENT MAY OCCUR WITHOUT CORRECT PRESSURES. GAUGE SET-UP, P/N
942280, IS AVAILABLE FOR CHECKING THESE PRESSURES. SET PRESSURES PER INSTRUCTIONS FURNISHED WITH
APPLICABLE HYDRAULIC INSTALLATION TOOL INSTRUCTION MANUAL. SEE “SETTING PRESSURES”.
WARNING:
GAGE BILT RECOMMENDS THAT ONLY GAGE BILT POWERUNITS BE USED FOR GAGE BILT INSTALLATION
EQUIPMENT. HYDRAULIC POWERUNITS THAT DELIVER HIGH PRESSURE FOR BOTH PULL AND RETURN ARE NOT
EQUIPPED WITH RELIEF VALVES AND ARE SPECIFICALLY NOT RECOMMENDED, AND MAY BE DANGEROUS.
CAUTION:
KEEP DIRT AND OTHER FOREIGN MATTER OUT OF HYDRAULIC SYSTEMS OF TOOLS, HOSES, COUPLERS AND
POWERUNIT . DO NOT LET HOSE FITTINGS AND COUPLERS CONTACT A DIRTY FLOOR OR UNCLEAN WORKING
SURFACE. FOREIGN MATTER IN HYDRAULIC FLUID MAY CAUSE TOOL AND AND THE POWERUNITS VALVES TO
MALFUNCTION.
INITIAL USE
:
1. Filling the Reservoir.
A. Clean the area around the filler cap to remove all dust and grit. Any dirt or dust in the oil can damage
the pump.
B. Set all pistons to the return position.
C. Remove the filler cap and fill with hydraulic oil to within 1/2" from the top of the filler hole. Replace filler
breather cap.
D. Hydraulic fluid is not shipped with the GB910 Powerunit and is not available from Gage Bilt Inc. Fire-
resistant hydraulic fluid must be used to conform with the Occupational Safety and Health
Administration (OSHA) regulation 1926.302, paragraph (d) "the fluid used in hydraulic powered tools
shall be fire-resistant fluids approved under Schedule 30 of the U.S. Bureau of Mines, Department of the
Interior, and shall retain its operating characteristics at the most extreme temperatures to which it will be
exposed." For ambient temperatures between 0 F and 130° F, a fluid with the viscosity range of 300
SUS at 100° F and 50 SUS at 210° F is recommended. Seals compatible with phosphate ester hydraulic
fluids are furnished with the GB910 Powerunit.
E. Connect the PULL pressure hose to the output marked PULL. Connect the RETURN to the output
marked RETURN.
F. Operate unit at 90-120 psi air pressure with a minimum hose ID of 1/2".
G. Cycle the pump (with tool attached) several times. Re-check the oil level in the pump reservoir with the
tool in the relaxed (return) position.
H. Check for leaks.
2. The GB910 powerunit and installation tool are ready for attaching the applicable nose assembly.
Note: Gage Bilt does not recommend using a pneumatic lubricator or adding pneumatic oil to the
air inlet on our tools or powerunits.
