FILLING AND BLEEDING TOOL
WARNING
DO NOT CYCLE TOOL WITHOUT AIR BLEEDER, OR THE SCREW AND STAT-O-SEAL, INSTALLED IN TOOL HEAD. SEVERE
PERSONAL INJURY MAY RESULT.
CAUTION
BEFORE FILLING HANDLE, AIR PISTON SHOULD BE ALL THE WAY DOWN.
CAUTION
WHEN FORCING PISTON ROD ASSEMBLY DOWNWARD WITH HEAD CYLINDER ASSEMBLY REMOVED,
HYDRAULIC FLUID WILL EJECT FORCIBLY FROM HANDLE.
To replace a small amount of oil in the tool, remove rear button-head cap screw (402482) and stat-o-seal (S572) attach the air bleeder
(704153) and connect tool to air line. Cycle tool 10 times. Disconnect air, remove the air bleeder, and reinstall the rear cap screw and
stat-o-seal. This will ensure the removal of any air from the hydraulic system and its replacement with fluid.
Should it become necessary to completely refill the tool (such as would be required after tool has been dismantled and reassembled),
take the following steps after depressing trigger
1. Remove head assembly from handle assembly. Slowly push piston completely forward. Remove adjuster ring (784138). Turn
adjuster knob assembly (784139) completely in clockwise, then back out two turns counterclockwise. This will set gage point #1
very close. It will need to be readjusted slightly after bleeding is complete using setting gage (784159).
2. Fill handle and the oil passage on top of handle with automatic transmission fluid, Dexron III or equivalent. When looking at the
top of the handle, the oil passage is the hole that is counterbored for S832 o'ring.
3. Replace head assembly with care, ensuring gasket (704129) and o'ring (S832) are properly installed. Tighten cap screws
(402479) uniformly to prevent leakage around gasket 40 inch lbs.
4. Remove button-head cap screw (402482) and stat-o-seal (572) from the front and rear hole. Using a pressure oil can (745163)
filled with automatic transmission fluid, Dexron III or equivalent, force the fluid into the front hole until it flows freely from the rear
hole until the air bubbles stop appearing at rear hole.
NOTE
If fluid does not flow freely, remove base cover and push air piston up about 1". This will open oil valve on piston rod assembly.
Replace base cover. Repeat step #4.
5. Remove bottle from front hole and place bottle at rear hole and reverse step #4.
6. Install front screw (402482) and stat-o-seal (S572).
7. Remove rear screw (402482) and stat-o-seal (S572), install bleeder bottle (704153) and connect tool to air line. Cycle ten to twenty
times to fully circulate fluid through hydraulic system.
DISCONNECT AIR FROM TOOL.
8.
air and cycle tool 10 more times. Check tool stroke, if stroke doesn't check .900" min., repeat steps 7 & 8.
CAUTION:
Use CAUTION when removing screws and 4oz bottle assy. hydraulic fluid may be under pressure.
TROUBLESHOOTING
Providing all maintenance conditions have been met, follow this systematic approach to diagnosis.
1. MORE THAN ONE PULL IS REQUIRED TO BREAK RIVET.
a) Tool needs to be bled. (See filling and bleeding instructions.)
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 TRIGGER IS DEPRESSED
a) Head Piston Rings (400845) and back-up ring (S657) could be worn or damaged. Replace.
b) Piston Rod Rings (S908) and (A-201) could be worn or damaged. Replace.
c) Muffler (744143) or filter inside valve spool assembly (743142) may be plugged. Clean thoroughly and back-blow with
compressed air.
d) Hole in metering screw in valve spool assembly (743142) may be blocked or damaged. Hole diameter should be .028". Clear
and size or replace.
3. NO OPERATION WHEN TRIGGER 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 (744144) breaks or dislodges, air will flow freely through the muffler (744143). Replace or reset. Valve spring
installation tool (744151) is recommended.
b)
Check o'rings on valve sleeve (743144), valve spool (743142), and valve plug (744142). If worn or damaged, replace. Valve
sleeve removal tool (744152) is recommended.
6. FASTENER STEM JAMMED IN NOSE ASSEMBLY
a)
Nose assembly components require service.
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.
AND DISCONNECTING THE AIR SUPPLY:
Remove bleeder bottle (704153), install screw (402482) and stat-o-seal (S572). Reconnect
DISCONNECT AIR FROM
