Leading Innovation in Torque and Tension Since 1968
The World’s Most Trusted Industrial Bolting Systems
SYMPTOM PROBABLE CAUSE REQUIRED ACTION
Cylinder/Tool leaks 1. Safety relief valve on swivel has lifted.
2. Blown O-ring in cylinder
3. Defective gland seal.
1A. Tighten all hose and couplers. If leak contin-
ues, adjust safety setting - Test #4
1B. Check to see if the system is properly plumbed
by running test #5 (high pressure on retract side
will lift the safety relief valve)
2. Replace O-Ring with proper high pressure O-
Ring. SHOP JOB
3. Replace gland seal. SHOP JOB
Tool operates backwards 1. Couplings reversed
2. Multiple hoses in even numbers
1. Run test #5. Replumb system as necessary.
2. As plumbed, HYTORC hoses may only be joined
together in odd numbers ONLY. If it is necessary to
use 2,4,6 hoses - make an adapter from spare high
pressure couplings and nipples.
Ratchet returns with retract stroke 1. Broken or otherwise inoperable drive
segment.
1. Replace drive segment and/or spring. SHOP
JOB.
Ratchet will not take successive strokes 1. Broken or otherwise inoperative drive
segment I or spring
2. Cylinder not retracting completely
3. Linkage between piston rod and drive
plates is broken
1. Replace drive segment and/or spring. SHOP JOB
2. Remove tool from nut and cycle freely for sev-
eral strokes. If problem persists, check pawls.
2A. Operator not allowing adequate time for cylin-
der to retract fully.
3. Replace parts as necessary - SHOP JOB.
Tool locks onto nut 1. Drive segment is loaded when the tool is
max’d out in torque
2. Tool is operating backwards
3. Tool is wedged under a xed object
1. Press advance button on remote and build pres-
sure - continue to press down on remote while
pulling back on one of the accuracy assurance
levers - release remote while continuing to hold
back on levers
2. Push advance button down - tool should immedi-
ately fall free- Run test #5
3. Remove shroud from around ratchet. Using any
tool available, pry the drive segment out of the
ratchet and at the same time pull back on the
accuracy assurance levers. Tool should swing free
or burn away the socket or obstruction.
