4. Hydraulic
fl uid overheats.
a. POWERIG
not operating properIy.
b. Hydraulic couplers not completely tightened.
c. Restriction in hydraulic line.
5. Tool operates erratically and fails to install
fastener properly.
a. Low or erratic hydraulic pressure; air in system.
b. Damaged or worn piston/anvil O-ring in tool.
c. Excessive wear on sliding surfaces of tool parts.
d. Relief Valve too short, worn, or peened over.

a. Broken pintail not removed from tool.
b. Incorrect
fastener
length.
Always check the simplest possible cause (such as
a loose or disconnected trigger line) of a malfunction
fi rst. Then proceed logically, eliminating other possible
causes until the cause is discovered. Where possible,
substitute known good parts for suspected defective
parts. Use this troubleshooting information to aid in
locating and correcting trouble.

AIR FITTINGS
1) Apply TEFLON
®
stick to male threads which do
not have pre-applied sealant per manufacturer’s
recommendations. (Proceed to All Fittings step 2)
HYDRAULIC FITTINGS
1) Apply Threadmate™ to male and female threads
which do not have pre-applied sealant per
manufacturer’s recommendations. (Proceed to All
Fittings step 2)
ALL FITTINGS:
2) Tighten to fi nger-tight condition.
3) Wrench tighten to 2-3 turns past fi nger-tight condition.
4) Final thread engagement can be checked (optional)
by measuring the dimension from the fl ange of male
fi tting to the end of the thread before assembly
and subtracting the distance under the fl ange after
assembly.
