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).
