GENERAL PRE-INSPECTION
•
CONTROL THAT THE TOOL IS INTEGRAL AND COMPLETE, AND THAT ALL BOLTS AND NUTS
ARE IN THEIR PLACE AND WELL TIGHTENED.
•
CHECK THAT POSSIBLE SAFETY DEVICES AND THE RETURN SPRING ARE EFFICIENT,
WITHOUT DEFORMATIONS AND IN THEIR ORIGINAL STATE. IF THEY HAVE BEEN MODIFIED OR
REPAIRED ADAPTING THEM, DISCARD THEM AND ORDER NEW PARTS.
•
IF SAFETY OR WARNING STICKERS ARE DAMAGED, ILLEGIBLE OR MISSING, ORDER NEW
PARTS CHECKING THE PART NUMBER ON THE TOOL PART LIST.
•
CONTROL THE ACCESSORIES:, HYDRAULIC FLEXIBLE HOSES AND QUICK COUPLERS ARE OF
THE RIGHT TYPE AND INTEGRAL, ORIENTED IN THE RIGHT WAY AND THEY ARE NOT THE
CAUSE OF THE PROBLEMS.
•
CONTROL THE QUICK COUPLERS ON THE TOOL AND ON THE FLEXIBLE HOSES, MAKE SURE
THEY ARE CORRECTLY INSTALLED, THAT THEY CAN BE CONNECTED IN THE RIGHT WAY TO
ASSURE THE RIGHT OIL DIRECTION.

DISASSEMBLY
•
REMOVE THE PIG-TAIL HOSES OR THE QUICK COUPLERS FROM THE TOOLS, MEMORIZING
THE ORIGINAL POSITION OF THE PARTS. REMIND THAT THE FEMALE QUICK COUPLERS
SHOULD BE INSTALLED ON THE TOOL IN THE HOLE WITH P PUNCHED (OIL ENTERS THE
TOOL), COLLECT THE DRIPPING OIL IN A CLEAN CONTAINER. CHECK IF THE OIL IS DIRTY,
OR WITH IMPURITIES, THIS WILL HELP IN FINDING SOME CAUSES OF PROBLEMS.
•
IF A VICE IS USED FOR HOLDING THE TOOL, ALWAYS COVER THE JAWS OF THE VICE WITH
SOFT PROTECTIONS, AND BLOCK THE TOOL IN ITS MORE SOLID POINT, FOR NOT
DEFORMING THE PARTS.
•
IF IT IS POSSIBLE TO MEMORIZE THE ORIGINAL POSITION OF THE SCREWS AND THEIR
TENSION.
•
IF IT IS POSSIBLE TO DISASSEMBLE ONLY THE PART INVOLVED IN THE PROBLEM,
MEMORIZING THEIR ORIGINAL POSITION AND THE ORIENTATION OF THE SEALS.
THE HYDRAULIC COMPONENTS OF DOA PRODUCTS ARE MANUFACTURED WITH FINE
WORKMANSHIP AND STRICT TOLERANCES. BE CAREFUL NOT TO DEFORM AND DROP THEM. IT
IS COMPULSORY TO KEEP EVERYTHING CLEAN. WHEN IT IS POSSIBLE INSTALL PARTS WITH
MORE THAN ONE INSTALLABLE POSITION, IN THE ORIGINAL POSITION.
THE HYDRAULIC MOTOR SHOULD NEVER BE DISASSEMBLED. IF THE MOTOR SHOWS OIL LEAKS
OR OTHER DAMAGES IT MUST BE SHIPPED TO DOA FOR REPAIR
SEALS - O-RINGS
•
CONTROL THE CONDITION AND AREA OF WEAR, TRYING TO FIND THE CAUSE (DIRTY OIL,
EXCESS OF TURNS, OTHER). IT IS ALWAYS BETTER TO REPLACE ALL SEALS THAT HAVE
BEEN DISASSEMBLED, IN PARTICULAR THE "DYNAMIC SEALS", WHICH SEAL MOVING OR
ROTATING PARTS. THESE SEALS ARE MORE SUBJECT TO WEAR.
