Adjusting the flow rate
To avoid the possibility of personal injury or death
be aware of the following when making
adjustments:
A
The 3-point hitch operation is influenced by the
combination of the adjustment of the flow
control valve and the engine speed.
A
The 3-point hitch may rise slowly or not at all at
low engine rpm.
A
The 3-point hitch may rise suddenly if engine
rpm is increased, or, flow control adjustment is
changed.
Refer to the illustration below.
1. The flow rate for the remote control valves (2) or (3),
located on above the flow control valve (4), can be
adjusted.
2. Turn the flow control knob (5) counterclockwise (A),
and the flow rate for the remote control valves (2) or (3)
increases. A clockwise turn (B) of the knob causes the
flow to decrease. If the knob is turned all the way (C),
there will be no flow.
3. To adjust the flow rate, set the engine speed to the
operating RPM, turn the flow control knob once all the
way clockwise (C), and then turn it gradually
counterclockwise until a required flow rate is reached.
A
Full adjustment of the valve will occur in approximately
1 1/2 revolutions of the flow control knob. Turning the
flow control knob beyond this point will have no affect
on the flow rate.
A
When there is no need to adjust the flow rate, turn the
flow control knob all the way counterclockwise and
keep it in this position.
B
Positions and advantages of the flow
control valve
Refer to illustration below.
C
Position 1
1. The attachment control speed (hydraulic motor RPM,
for example) of the remote control valve (1) can be
maintained at a constant level within limits.
2. The remote control valve (1) and the 3-point hitch can
be operated at the same time. The 3-point lift speed
will be influenced by the level of flow required at
remote control valve (1).
