5. Operation

• Withthepowersourceinthe"OFF"position,connectthehoses.Donotdragtheservicehosebypulling

withthetool.Looptheservicehoseintheworkareainsuchawaytorelievestressonthehoseandquick

disconnectttingswhileworking.Beawareofhoselocationatalltimes.

• Connectthetooltothepowersource.

• Placethegrinderontherailwiththefronthookovertherailheadandthegrindingheadinthegeneralgrinding

area.

• Graspthetoolrmlybeforeengagingthetrigger.Therewillbeaslighttorquereactionwhenthestoneis

activated.

5.1. Grinding head position

Thestoneisalwaysinthehorizontalposition.Thehookisalsousedinthisposition.Thispositionisusedfor

thermiteweld,proleblend-insandremoval.

6. Review of hydraulic principles

Tool circuit

6.1. Hydraulic formulas

Example:HPrequiredtodeliver10GPMat1500PSI.

EstimatedHPdeliveredbypumporusedbytool

6.2. Back pressure

Backpressuremeasuredatthetoolreturnportmustnotexceedthemanufacturersbackpressurerating.Most

manufacturerslistthemaximumbackpressurefortheirhydraulictoolsat250PSI.Backpressuremeasuredon

thereturnsideofthetoolistheforcerequiredtogettheoilbacktothetank.Inalmostallcasesthelowertheback

pressurethebetterthetoolperformance.First,thebackpressureissubtractedfromthemaximumtoolpressure

toarriveatamaximumtooloperatingpressure.Forexample,toolswith2000PSIoperatingpressureareinstalled

onasystemwith250PSIbackpressure.Thisleaves1750PSIasamaximumtoolpressure.Imagineasystem

with500PSIbackpressure.2000Minus500PSIbackpressureleavesonly1500PSIforthetool.Second,tools

aredesignedforpressuretobuildonthepressuresideofthetool.Iftoomuchpressurebuildsonthereturnside,

notonlyisperformancee󰀨ected,butsealsmayblow.Thisiswhyitisveryimportanttodirecttheowintothetool

correctly.Reversingthehosestotestmayresultinblownseals,damagetothetool,andpersonalinjury.
