B. TROUBLESHOOTING
Undernormaloperatingconditions,andwithpropermaintenance,thetorquegaugeandloadcellsystemaredesignedtogivelasting
trouble-freeperformance.Faultyindicationonthegaugewillveryoftendefineafaultwithinthegauge.
1. Symptom: No indication on gauge.
  PossibleProblem: Obstructioninhydraulichose.
  Solutions: Checkhydraulichoseforkinks.
   Replacehydraulichose.
  PossibleProblem: Lossofhydraulicfluid.
  Solution: Rechargehydraulicfluid(seeSection6.C).NOTE:Ensureanybreachesinthehydraulicsystem
   betweentheloadcellandtorquegaugearerepairedtopreventfurtherfluidloss.
  PossibleProblem: Internalmechanismoftorquegaugeisdamaged.
  Solution: Replacegauge.
2. Symptom: Gauge indication unexpectedly high.
  PossibleProblem: Excessivehydraulicfluid.
  Solutions: Completelydrainhydraulicfluidfromtorquegauge/loadcellsystem.Rechargefollowingthe 
   procedureinSection6.C.
  PossibleProblem: Internalmechanismofgaugeisdamaged.
  Solution: Replacegauge.
  PossibleProblem: Incorrecttorquegaugeinuse(notpartoftheoriginaltorquegauge/loadcellpair).
  Solution: Replacegaugewithgaugeproperlycalibratedfortheloadcellinservice.
3. Symptom: Gauge indication unexpectedly low
  PossibleProblem: Insufficienthydraulicfluid.
  Solution: Rechargehydraulicfluid(seeSection6.C).NOTE:Ensureanybreachesinthehydraulicsystem
   betweentheloadcellandtorquegaugearerepairedtopreventfurtherfluidloss.
  PossibleProblem: Obstructioninhydraulichose.
  Solutions: Checkhydraulichoseforkinks.
   Replacehydraulichose.
  PossibleProblem: Snublinenotatright-angletotonghandle.
  Solution: Checkangleofsnublineandcorrectifnecessary.
  PossibleProblem: Internalmechanismofgaugeisdamaged.
  Solution: Replacegauge.
  PossibleProblem: Incorrecttorquegaugeinuse(notpartoftheoriginaltorquegauge/loadcellpair).
  Solution: Replacegaugewithgaugeproperlycalibratedfortheloadcellinservice.
4. Symptom: Gauge indication is erratic or sluggish
  PossibleProblem: Insufficienthydraulicfluidintorquemeasurementsection.
  Solution: Rechargehydraulicfluid(seeSection6.C).NOTE:Ensureanybreachesinthehydraulicsystem
   betweentheloadcellandtorquegaugearerepairedtopreventfurtherfluidloss.
  PossibleProblem: Lossofdampingfluidintorquegauge.
  Solution: Topuporrefilldampingfluid(NOTE:Ensureleakagepointsingaugeareidentifiedandrepaired
   topreventfurtherlossofdampingfluid).
  PossibleProblem: Airbubblesinhydraulicfluidinthetorquemeasurementsystem.
  Solution: Bleedairfromloadcellandtorquegaugeandtopupfluid(ifnecessary)asperSection6.C.
  PossibleProblem: Internalmechanismofgaugeisdamaged.
  Solution: Replacegauge.
IF TROUBLESHOOTING REVEALS THAT THERE IS INSUFFICIENT FLUID IN THE SYSTEM,
BEFORERECHARGING,CHECKTHATALLSYSTEMCOMPONENTSAREFREEFROMDAMAGE.
THISWILLENSURETHATFLUIDLOSSWILLNOTCONTINUEAFTERRELOADING
