Providing all maintenance conditions have been met, follow this systematic approach to diagnosis. 

 

1.  NO OPERATION WHEN ELECTRIC ACTUATOR (240122) IS DEPRESSED 
    a.) Check Powerunit power source. 
    b.) Control cord may be loose or damaged. 
    c.) Faulty electric actuator (240122). Replace. 
    d.) Check hydraulic couplings; tighten, repair or replace. 

 

2.  SLOW OR PARTIAL OPERATION WHEN ELECTRIC ACTUATOR (240122) IS DEPRESSED 
    a.) Low hydraulic pressure. Check powerunit, adjust. 
    b.) O’ring (403810) could be worn or damaged. Replace. 
    c.) Excessive wear or scoring on moving parts.  Check and replace faulty parts. 

 

3.  TOOL OPERATES IN REVERSE 
    a.) Tool stops in back position. Hydraulic hoses (206119) are reversed. Correct. 

 

4.  HYDRAULIC OIL OVERHEATS 
   a.) Powerunit motor rotation reversed. Electrical connections reversed. See powerunit instruction manual. 
   b.) Restrictions in either hydraulic lines, hydraulic hoses (206119) or hydraulic coupling-male (585047) and hydraulic 
 

  coupling-female (585038). Check and tighten, clean or replace. 

 

5.  OIL LEAKAGE 
    a.) Hydraulic oil leaks from connections. Tighten threaded  connections. 

(See hydraulic thread preparation page 5)

 

    b.) Oil leaks from tool. Determine source of leak and replace worn or defective o'rings and back-up rings. 

 

6.  PINTAIL GROOVES STRIPPED DURING PULL STROKE 
   a.) Tool must be pushed onto fastener fully. 

   b.) Chips may have collected in super grip jaw assy (30601-CS) Disassemble piston assembly (705210), clean super 

         grip jaw assy (30601-CS) in mineral spirits or use a  sharp pointed object to remove chips.  

  

 

   c.) Super grip jaw assy (30601-CS) may be worn or damaged. Replace. 
   d.) Pintail too short for super grip jaw assy (30601-CS) to properly grip. Select proper grip length fastener. 
   e.) Excessive gap between sheets. Reduce gap before attempting to install fastener. 

 

7.  NOSE ASSEMBLY WON'T ACCEPT FASTENER PINTAIL 
   a.) Spent fastener stem may be jammed in pulling head. Disassemble and check for worn or broken parts in nose  
 

  assembly. Replace defective parts and clean before reassembling. 

TROUBLE SHOOTING

 

OVERHAUL

 

 

WARNING

Disconnect tool from its power source before performing overhaul. 

 

WARNING

Tool must be maintained in a safe working condition at all times and examined on a  

                    regular daily basis for damage or wear. Any repair should be done by qualified personnel  
  

trained on Gage Bilt procedures.

 

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.  

 

If a tool is performing poorly or leaking badly, a complete overhaul may be necessary. Service Kit (206100) 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

7

 (Gage Bilt part  no. 402723) or other lubricant is recommended during reassembly to 

prevent tearing or distorting of o

=

rings. 

 

Disconnect hydraulic hoses and electrical cord or air line from powerunit. Remove hydraulic coupler– female (585038) 
and  hydraulic coupler– male (585047) from hydraulic hoses (206119) and drain. Push piston assy (705210) back into 
cylinder assy (700338) to empty all oil from tool. Push piston assy (750210) back to the front of cylinder assy (700338).  

 

Unscrew  socket  head  cap  screw  (206118)  from  retaining  ring  (206117)  using  a  spanner  wrench  to  remove  retaining 
ring. Push piston assy (705210) back until cylinder cap assy (206115) falls out of cylinder assy (700338). Push piston 
assy (705210) out the rear of the cylinder assy (700338). Remove loading valve (206109) from the piston assy (705210). 
Using a small blunt object, remove o

=

rings and back-up rings from components. Use extreme caution not to damage, 

mar or nick any smooth surface that comes in contact with seals. 

 

Clean parts in mineral spirits or other o

=

ring compatible solvent being sure to clean o

=

ring grooves. Inspect compo-

nents for scoring, excessive wear or damage. 

 

Reassembly  sequence  is  opposite  of  disassembly.  Be  sure  relative  positions  of  o

=

rings  and  back-up  rings  are  as 

shown in exploded view and parts list. Unloading valve (206109) must be installed with flats towards the rear of adapt-
er. See hydraulic thread preparation (page 5) for reassembly of hydraulic hoses (206119).
