PLEASE CONTACT GAGE BILT FOR ALL OTHER SERIAL NUMBERS.
Providing all maintenance conditions have been met, follow this systematic approach to diagnosis.
1. MORE THAN ONE PULL IS REQUIRED TO BREAK FASTENER.
a)
Tool needs to be bled. See filling and bleeding procedure pg. 11).
b)
Spring has fatigued, replace.
c)
Jaws are stripped or packed with chips. Clean or replace.
d)
Incorrect nose tip.
2. SLOW OR PARTIAL OPERATION WHEN THE ACTUATOR LEVER ASSEMBLY (704343) IS DEPRESSED.
a) Polyseal (405865) and o
’
ring (400788) on piston (703607) could be worn or damaged. Replace.
b)
Back
-
up ring (401102) and o
’
rings (S945) on piston rod assembly (704138) could be worn or damaged. Replace.
c)
Muffler (704146) or filter inside valve spool assembly (703142) may be plugged with dirt. Clean thoroughly and back
-
blow with compressed air.
d)
Hole in metering screw in valve spool assembly (703142) may be blocked or damaged. Hole diameter should be .028" (.71 mm).
Clear and size or replace.
3. NO OPERATION WHEN ACTUATOR LEVER ASSEMBLY (704343) IS DEPRESSED.
a)
Tool seized due to mechanical failure or damaged parts.
4. OIL LEAKAGE.
a)
DO NOT
OPERATE WITH OIL LEAKING FROM TOOL. HIGH PRESSURE OIL MAY CAUSE SEVERE PERSONAL INJURY.
b)
Any oil leaking externally should be traced to its source. An o'ring or seal that leaks should be replaced.
5. AIR BYPASS FROM VALVE HOUSING.
a)
If the spring (704141) breaks or dislodges, air will flow freely through the muffler (704146). Replace or reset. Valve
spring installation tool assembly (704262) is recommended.
b)
Check o'rings on valve sleeve (703139), valve spool assembly (703142), and valve plug (704145). If worn or damaged,
replace. Valve sleeve removal tool (704163) is recommended.
6. FASTENER STEM JAMMED IN NOSE ASSEMBLY.
a)
Nose assembly components require service.
DISCONNECT AIR FROM TOOL
, remove the nose from the tool and
disassemble. Replace worn or broken parts. Clean the surface the jaws ride on.
b)
Stems lodged side by side in the follower. Disassemble, remove stems, and reassemble.
c)
Incorrect follower.
7. PINTAIL IS NOT BEING VACUUMED THROUGH.
a.)
b) Check vacuum pressure using vacuum gage (703567) (sold separately).
Note: Offset nose assemblies must be check by removing the vacuum line from the nose assembly.
c) Press gage against the vacuum line or nose assembly to create seal.
Optimum vacuum pressure at nose assembly must be between 15
-
22 inHg.
(381
-
558.8 mmHg).

HOW TO CLEAN VACUUM REGULATOR
1.
Remove vacuum regulator (703515) from tube and fitting.
2.
Remove (4) S.H.C.S. from front of regulator and disassemble.
3.
Clean both pieces in clean mineral spirits and blow dry.
4.
Reassemble and connect hoses.
5.
Check vacuum pressure using vacuum gage (703567) (sold separately).
Press gage against the vacuum line or nose assembly to create seal.
Optimum vacuum pressure at nose assembly must be
between 15
-
22 inHg.
(381
-
558.8 mmHg).
Note: The vacuum regulator may visually appear clean, but still may be
contaminated with a thin film, therefore, the steps above should
be performed to assure best performance.
