WARNING:
Only qualified and trained personnel should perform overhaul.
WARNING:
Personnel must read and understand all warnings and cautions.
WARNING:
Tool must be maintained in a safe working condition at all times and examined on a daily basis for damage or
wear. Any repair should be done by qualified personnel trained on Gage Bilt procedures.
WARNING:
Disconnect tool from its power source before performing overhaul. Severe personal injury may occur if power
source is not disconnected.
WARNING:
Excessive contact with hydraulic oil and lubricants should be avoided (See SDS documents for all applicable
materials
WARNING:
When operating, repairing or overhauling tool, wear approved eye protection. Do not look in front of tool or
rear of tool when installing fastener.
WARNING:
Use only Gage Bilt hydraulic hoses and couplings, or equivalent, rated for 10,000 psi. (689.5 bar) working pressure.
WARNING:
Ensure air hose is securely connected to avoid possible hose whipping (Air Actuated Tools only).
WARNING:
Do not exceed the maximum relief-valve setting stated on the tool and manual.
WARNING:
Relief valve must be installed with four flats towards the rear of the cylinder.
Note:
Dispose of hydraulic oil in accordance with manufacture safety datasheet.
All tool materials are recyclable except rubber o'rings, seals and wipers.
If a tool is performing poorly or leaking, a complete overhaul may be necessary. Service Kit (GB2620PTKS) contains a complete set
of o'rings, back-up rings and screws.
Perform overhaul in a clean, well lit area using care not to scratch or nick any smooth surface that comes in contact with an o'ring.
Use of Lubriplate® #630-AA (Gage Bilt part no. 402723) or equivalent during reassembly to prevent tearing or distorting of o'rings.
1. Disconnect control cord assy (585034) / air line (750154) from power supply.
2. Disconnect hydraulic hose assy (585054) power supply.
3. Remove hydraulic coupler-male (585047) & hydraulic coupler-female (585038) from hydraulic hose assy (585054) and drain
into a container.
4. Remove retaining ring (401514), split ring (505003), retaining sleeve (504102) and nose assembly.
5. Remove deflector (262032), three socket head cap screws (400060), barbed retainer (262030) and locator (582127).
6. Push piston (262004) rearward until remaining hydraulic oil is drained.
7. Remove end cap (262014) using Hex Key (263020) supplied with tool.
8. Push piston assy (262006) rearward until it is out of cylinder assembly (262008).
9. Remove front gland (262012), polyseal (407408), wiper housing (262007) and wiper (407407).
10. Remove all O'rings, Back-up rings, Wipers, Polyseals and Glyd Rings. Clean parts in mineral spirits or other o'ring compatible
solvent being sure to clean o'ring grooves. Inspect components for scoring, excessive wear or damage.
11. Reassembly sequence is opposite of disassembly. Be sure relative positions of o'rings and back-up rings are as shown in
exploded view and part list.
Coat hose fitting threads with a non-hardening teflon thread compound such as Slic-tite® (Gage Bilt part no. 403237). DO NOT USE
TEFLON® TAPE. Apply hot glue to wire connections to ensure wires DO NOT contact each other or handle assy. (See hydraulic
thread preparation pg.10).
Apply hot glue to wire connections of the electric actuator (240122) to ensure wires DO NOT contact each other or handle assy.
(Electric actuated installation tool GB2620PT only).
1.
When tool life is met, drain hydraulic oil from tool and dispose of the hydraulic oil in accordance with SDS datasheet.
2.
Disassemble tool and remove all rubber o'rings, seals, wipers and hydraulic hoses. All tool materials are recyclable except rubber
o'rings, seals, wipers and hydraulic hoses. Dispose of rubber materials in accordance with all environmental regulations applicable
in your area.
