Often a carrier is equipped with an auxiliary control valve (see Figure 1),
this valve can be adjusted to provide the correct amount of oil flow to the
compactor. A pressure relief cartridge can also be installed to protect the
hydraulic components.
Make sure that oil is not routed back through the return port of this auxil-
iary valve. Instead, send the oil directly back to the tank, via the cooler
and filter.
If the circuit is plumbed using both ports on the auxiliary valve, the
return line should have a bleed line connected to tank, to prevent damag-
ing pressure spikes from the returning oil.
