Understanding Hydraulics
Before connecting the hoses to the power
unit ensure that the power unit is powered
off. The quick disconnect couplers must be
clean and free on any dirt or contaminants.
Clean the quick disconnect couplers with
brake wash if necessary.
The hydraulic impact hammer is usually
shipped with the hoses attached to the
hammer. If the hoses have been shipped
separately, they must be connected as
shown.
There are three hoses leading from the
hammer that must be connected to the
power unit to begin operation. The hoses
attach to the power unit by screwing the
quick disconnect couplers onto the proper
couplers of the power unit. The couplers on
the power unit are mated with the couplers
on the hammer, so there is no chance of
putting them on backwards.
Pressurizing the system while there
is air entrained in the fluid may
cause damage to the components.
Let the system run at idle for an
additional 10 minutes
to allow the
air to rise into the airspace of the
hydraulic reservoir.
Connecting the hydraulic hoses
Connecting the hoses is one of the most
critical aspects of commissioning an APE
equipment. Take extreme care to keep these
connections absolutely clean. This procedure
is one of the most common ways for foreign
particles to be introduced into a hydraulic
system.
New hydraulic fluid is NOT clean oil!
Oil must meet ISO cleanliness code
