Adjusting the
Counterbalance
T he counterbalance dial ( Figure 60 ) is used to
adjust the pressure in the counterbalance circuit.
R ecommended counterbalance pressure is 620 psi.
R otate the adjusting dial ( Figure 60 ) cloc kwise to
increase the pressure or countercloc kwise to decrease
the pressure .
