Operating Instructions, Form No. 102875, Back sheet 4 of 8
DIRECTIONAL CONTROL VALVE OPTIONS
NOTE: • Some valves return fluid to the reservoir or bladder when the pump stops or when the valve is
shifted. The correct valve must be used, especially when lifting a load.
• "Hold-to-run" controls are recommended and must be used with correct valves for certain
applications, especially when lifting a load.
• Not all valves fit on all pumps.
DANGER: When lifting or lo
wering a load
, the load must be under operator control at all times and
others must be clear of the load. Use blocking and cribbing to guard against a falling load.
Do not drop the load. The use of a load lowering or metering valve is recommended in
addition to the pump directional control valve.

RELEASE position. In this position, the cylinder will
advance when the pump is running and
retract
when the
pump is stopped.
