Using Hydraulic Cylinder Implement
NOTICE: Match Quick Disconnect Couplers
If necessary, replace coupler fittings with implement-matching couplers. Brave does not recommend adapters;
they may restrict flow and limit operation.
1. Connect Hoses (Engine Off)
• 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.
• Models HBHR are equipped with a spring to center 3 position 4-way hydraulic valve. The handle will
center itself to neutral when the operator removes his hand from the valve. This type of valve can cycle
both hydraulic cylinders and hydraulic motors. Refer to the diagram below to determine what port is
supply and return when the handle is shifted in either direction. Exercise caution when powering
equipment where damage can occur if the oil flow is reversed. Understand the flow of oil with respect
to the handle operation on your power unit if equipped with a directional control valve.
• Models HBHS can be ordered with quick coupler plumbing kits, directional control valve plumbing
kits, and HBHS600 units can be equipped with a return line heat exchanger kit. Please refer to the kit
directions to determine the supply & return ports of the directional control valve or quick coupler
plumbing kit.
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.
