If necessary, adjust the relief valve screw until the de-
sired pressure is attained. Turn the screw in to increase
counterbalance pressure and turn the screw out to de-
crease counterbalance pressure. Adjust nearer the high
end of the range for improved hill climbing or nearer the
low end for improved quality−of−cut.
