VALVE ADJUSTMENT
(Refer to Table 1)
1. See machine servicing instructions to properly reinstall accumu-
lator charging valve. Tee an accurate pressure gauge on an
accumulator line.
2. Start pump and allow approximately one minute for charging to
start (pressure in gauge will read accumulator precharge plus).
If valve does not begin to charge remove plug (8) and turn screw
(10) in, stopping when gauge shows an increase in pressure.
Check the high limit specifications (see TABLE 1) and adjust
screw (10) until the high limit setting is met. Reinstall plug (8).
This pressure can be checked correctly only if after each adjust-
ment of screw (10) the accumulator pressure is reduced below
the low limit setting and the system recharges the accumulator
pressure to its high limit. Repeat process until high pressure
setting is accurately adjusted. NOTE: Be sure to reinstall plug
(8) before starting pump.
3. Torque plug (8) 47.5-54.2 N·m (35-40 lb·ft).
