IF A FLEXIBLE HOSE FULL OF OIL REMAINS UNDER THE SUN, THE OIL EXPANSION DUE TO THE HEAT
CAN CAUSE A PRESSURE INCREASE AND PREVENT THE CONNECTION OF THE QUICK COUPLERS. TO
DECREASE PRESSURE, LOOSEN ONE COUPLER, DRIPPING SOME OIL DROPS DE-PRESSURIZING THE
HOSE.
THE OPERATOR MUST BE FAMILIAR WITH THE EFFECT TO THE TOOL DERIVING FROM THE POSITION
OF THE CONTROL VALVE, OPERATOR MUST KNOW WHAT HAPPEN WHEN HE OPEARTES THE
CONTROL VALVE
5. Thus the hydraulic connection is completed.
Accelerate the engine as needed and use tool by operating on the pack control valve , be sure
that the action needed from the tool is definitely deriving by the position of pack control valve
END OF OPERATIONS
1. Lay down the tool avoiding and limiting contacts with the mud and dirt, if possible.
2. Put the flow lever of the power pack in
OFF
position, blocking the oil supply to the tool.
3. Stop the engine
4. Disconnect the tool from the flexible hose and disconnect the flexible hose from the power pack.
5. Roll up the flexible hose in circles of about 60 cm of diameter, cover the couplers with the protection
plastic caps.
6. Store the power pack when the muffler and the engine are cooled down for avoiding possible risks of
fire and accident. Store the power pack and the equipment in a safe place repaired from bumps and
atmospheric agents
7. If the power pack should be transported on trucks take care that the machine is loaded in a proper way
and blocked for avoiding tilting and harmful jerks and bumps that could damage both the power pack
and the vehicles and cause accidents.
IF DURING THE WORK FUNCTIONING OR OTHER PROBLEMS APPEAR, INDICATE THE FAILURE AND
REPAIR IT IMMEDIATELY FOR AVOIDING THE ACCIDENTAL USE OF THE DAMAGED OR FAULTY MACHINE
BY OTHER COLLEAGUES. THIS COULD CAUSE DANGEROUS SITUATIONS.
