THE HYDRAULICS SYSTEM MAY HAVE “TRAPPED” HIGH-
PRESSURES EVEN WHEN DIESEL IS OFF. ALWAYS RELIEVE
THESE TRAPPED PRESSURES BY RATTLING THE CONTROL
LEVERS ABOUT THEIR CENTERED-NEUTRAL POSITIONS
(WITH THE DIESEL SHUTDOWN) BEFORE LOOSENING ANY
SYSTEM CONNECTIONS.
SOME MACHINE COMPONENTS COULD HAVE GRAVITY
PULLING ON THEM AS THEY ARE HYDRAULICALLY HELD IN
PLACE. ALWAYS STOP AND THINK FIRST IF A BLADE OR
OTHER MACHINE COMPONENT NEEDS TO BE REPOSITIONED
TO ITS “DEAD END” (OR OTHER POSITION) SO IT WILL NOT
MOVE BY GRAVITY
WHEN A HYDRAULIC CONNECTION IS
LOOSENED FOR REPAIR.
THE HYDRAULIC CYLINDERS COULD BE HOLDING A
PARTICULAR COMPONENT (SUCH AS A “BLADE”) IN A
PARTICULAR POSITION WHEN THE DIESEL IS OFF. AN
EXAMPLE OF THIS IS WOULD BE THE SLIDER BLADE HELD
UPWARD IN ITS “HOME” POSITION BY THE OIL “LOCKED”
INSIDE ITS CYLINDERS WITH DIESEL OFF. IF A HYDRAULIC
HOSE OR FITTING IS THEN WORKED-ON, GRAVITY
WILL
MOVE
THE COMPONENT TO A NEW POSTION IN A
UNCONTROLABLE FASHION. FAILURE TO ACCOUNT FOR THIS
FACT COULD RESULT IN SERIOUS INJURY OR DEATH.
OFTEN YOU CAN PURPOSEFULLY MOVE THE COMPONENT TO A
POSITON WHERE GRAVITY CAN NOT MOVE IT
BEFORE
WORKING ON THE HYDRAULICS.
SOMETIMES YOU WILL NEED TO SECURE THE COMPONENT IN
PLACE BY WELDING TEMPORARY STEEL “BLOCKING” OR
“STOPS” ONTO THE PACKER.
CALL LOADMASTER IF YOU HAVE ANY DOUBTS ABOUT THE
CORRECT AND SAFEST METHODS OF DOING THIS.
HYDRAULIC HOSES AND TUBING MUST BE INSPECTED ON A
DAILY BASIS FOR LEAKS, CUTS, ABRASIONS, DAMAGE,
RUBBING (NO CLEARANCE IN ROUTING), BEFORE THE TRUCK
IS PUT IN SERVICE. IF YOUR INSPECTION DISCOVERS SUCH
ADVERSE CONDITIONS, THE SITUATION MUST BE
CORRECTED BEFORE TRUCK CAN BE PLACED IN SERVICE.
LOADMASTER RECOMMENDS YOU REPLACE
ALL
OF YOUR
RUBBER HOSES AND THE CLAMPING AT LEAST EVERY THREE
YEARS.
FAILURE TO CLOSELY INSPECT AND MAINTAIN YOUR ELITE
AND CHASSIS COULD LEAD TO SERIOUS INJURY.
NEVER OPERATE THE HYDRAULIC SYSTEM IF ANY LEAK IS
PRESENT. SERIOUS INJURY MAY RESULT.
ALL OF THE ELITE’S PRESSURE GUAGE READINGS ARE TO BE
TAKEN AT THE GAUGE STEM LOCATED AT THE INLET COVER
OF THE BODY-MOUNTED VALVE! USE A GLYCERIN FILLED
GUAGE ON THE END OF A 24” HOSE (1/4” DIAMETER WITH
3000 PSI WORKING PRESSURE RATING) THAT ALLOWS YOU
TO BE FULLY OUTSIDE THE BODY WITH BOTH FEET ON
GROUND AND THEN TAKE THE GAUGE READING. DIESEL
MUST BE SHUTDOWN AND KEYS IN YOUR POCKET BEFORE
ENTERING THE BODY THROUGH THE ACCESS DOOR TO
COUPLE THE GAUGE COUPLER.
NEVER ATTEMPT TO READ A GLYCERIN-FILLED GAUGE WHICH IS
ATTACHED TO THE INLET COVER OF THE
TAILGATE
-MOUNTED
VALVE. ALWAYS COUPLE YOUR GLYCERIN FILLED GAUGE TO THE
BODY-MOUNTED VALVE’S GUAGE STEM. ALL LOADMASTER PRESSURE
SPECS ARE CHECKED/ADJUSTED AT THE BODY-MOUNTED VALVE’S
GAUGE STEM.
