Using Hydraulic Cylinder Implement
NOTICE: Match Quick Disconnect Couplers
The Hydraulic Power Pack is equipped with 1/2” quick-disconnect couplers. If necessary, replace with
implement-matching couplers. Hydra Buddy™ does not recommend adapters; they may restrict flow and limit
operation.
1. Connect Hoses:
 Before connecting your implement hoses to the Hydraulic Power Pack, you must determine which hose
is the pressure or forward acting hose. Consult your implement owner’s manual or labels to determine
which hose is the “SUPPLY” hose.
 Once the implement SUPPLY port has been determined, connect the “SUPPLY” hose to Hydraulic
Power Pack’s port labeled “SUPPLY”. Connect the implements RETURN line to Hydraulic Power
Pack’s port labeled “RETURN”.
WARNING: Crush Hazard
The Hydraulic Power Pack valve does not have a positive locking device to hold the cylinder in position. Always
use a mechanical lock to prevent the cylinder from creeping/drifting.
WARNING
Applications with large cylinders can excessively deplete the Hydraulic Power Pack’s hydraulic tank.
DO NOT use this unit in applications where more than 75% of the hydraulic fluid is purged from the hydraulic
tank or with a cylinder storing a larger oil reserve than the Hydraulic Power Pack.
DO NOT attempt to add more hydraulic fluid during operation to extend the hydraulic capacity.
Failure to follow these warnings could result in damage to property/equipment, personal injury, and death in
serious cases.
2. Start Engine:
 Place the control valve handle in the center (neutral) position.
 Re-start warmed-up engine per the manufacturer’s instructions.
 Place the engine throttle control lever in the fast position.
 Push the valve handle slowly inward until it locks in position and implement is operational
3. Normal Operation:
 To raise the cylinder, push the handle inward until the desired height is reached, then return the valve
handle to the center (neutral) position. Important: block or lock the implement at the desired height. If
the implement is not locked into position, the Hydraulic Power Pack will allow the cylinder to drift.
 To lower the cylinder, pull the handle outward until the desired height is reached, then release the
handle (it will automatically return to the center position).
NOTICE: When the valve handle is pushed inward, it locks in place. You must then pull the handle back to the
center (neutral) position to stop cylinder movement.
4. To Stop or Remove Attached Implement with Hydraulic Cylinder(s):
 To remove the unit, first place the implement cylinder in the fully retracted position (so the rod is inside
the cylinder barrel).
 Then, place the valve handle in the center (neutral) position.
 Turn engine off.
 Move the valve handle to the forward position for four (4) to five (5) seconds, then to the reverse
position for four (4) to five (5) seconds to release system pressure.
 Disconnect the hoses.
