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.
