Starting and Warm-up Before Use
1. If the hydraulic power unit is equipped with a directional control valve, place the Hydraulic
valve handle in the neutral position. If unit not equipped with a directional control valve,
skip directly to step 6.
CAUTION: HBHS users without installed directional control valve
If the unit is not equipped with a directional control valve, please ensure the power unit is properly plumbed to
the powered equipment prior to attempting to start the engine. Unit cannot be run without implement attached.
Damage to engine and hydraulic components can occur.
2. Start the engine per the manufacturer’s instructions.
3. Once the engine has started, move the throttle down to the mid-range position and allow the
engine to run for ten (10) minutes to warm engine and hydraulic oil.
4. Turn engine off.
5. Clear line pressure by moving the Hydraulic Power Pack valve (if equipped) to the forward
position for four (4) or five (5) seconds, then to the reverse position for four (4) or five (5)
seconds to relieve pressure.
6. Attach implement’s hydraulic hoses (if applicable).
Your Hydraulic Power Pack is now ready for attachment to an implement.
For units that are plumbed directly to equipment, without a valve on the power pack, see the following
diagrams which show the supply and return ports and what type of connection is provided at these ports.
Remove port plugs/caps in order to attach to these ports.
