THREE-WAY-VALVE OPERATION
(Machines equipped with the piping common to
hydraulic breaker and crusher operation)
• Turn the three-way-valve to the position as shown in the
upper right illustration when using a hydraulic breaker to
allow the return oil to flow back to the line filter.
• Turn the three-way-valve to the position as shown in the
lower right illustration when using a hydraulic crusher.
After using a hydraulic crusher, be sure to turn the three-
way-valve back to the hydraulic breaker position (as
shown in the upper right illustration).
FLOW COMBINING VALVE OPERATION
The flow combining valve is located under the front outside of
the pump chamber.
• Turn the flow combining valve to the position as shown in
the left- right illustration when using a hydraulic breaker/
crusher so that the oil flows from the 2 pumps are not
combined.
• Turn the flow combining valve to the position as shown in
the right-right illustration when combining the oil flows
from the 2 pumps for increasing the flow rate. When the
oil flows from the 2 pumps are not combined, be sure
to turn the flow combining valve back to the hydraulic
breaker/crusher position (as shown in the left- right
illustration).
