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 LEGACY 
AND CHASSIS COULD LEAD TO SERIOUS INJURY. 

 
 

 
 

 
 

 
 

 
 

NEVER  OPERATE  THE  HYDRAULIC  SYSTEM  IF  ANY  LEAK  IS 
PRESENT. SERIOUS INJURY MAY RESULT. 

 
 

 
 
 

 
 

 
 

 

ALL OF THE LEGACY3’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.
