What is the HV18 Hydraulic Power Unit?
HV18 is a hydraulic power unit that connects to a carrier, such as a backhoe,
excavator or skidsteer loader, and uses that carriers main hydraulic circuit to
power a self contained 7-9 GPM (27-34 LPM) hydraulic circuit suitable for
running hand-held tools. Model HV18300 uses an input supply of 16-35
GPM (61-133 LPM) and model HV18301 uses an input supply of 13-25 GPM
(49-95 LPM).

Tool Setup
Do not install or perform maintenance while the
a hydraulic power source is connected. Accidental
engagement of the tool can cause serious injury.
Disconnect and depressurize the hydraulic power source
before installing or performing maintenance.
Check and Fill Hydraulic Oil Reservoir - Detail B
1. Remove the dipstick from the hydraulic reservoir.
2. Ensure the hydraulic oil level is between the max fill line and the bottom
of the dipstick.
3. If the hydraulic oil level is low, remove the hydraulic oil reservoir cap
using a crescent wrench.
4. Fill the hydraulic reservoir to the max fill line on the dipstick with an ISO
Grade 32 hydraulic oil.
Note: Use clean hydraulic oil and filling equipment. Only use hydraulic oils
recommended by STANLEY. See “STANLEY Recommended Hydraulic Oils” on
page 10.
5. Reinstall the cap before operation.

Connect to a Hydraulic Power Source - Detail C
1. Ensure the HV18 tool circuit control valve is in the off position.
Note: The off position is when the control valve pegs are in the deepest
groove of the valve, pushed all the way in.
2. Using a calibrated flow and pressure gauge, check the output of the
hydraulic power source. Ensure it matches the flow and pressure in
“Specifications” on page 10. Hydraulic fluid must be 50°F or above.
Preheat if necessary.
3. Ensure that the hydraulic power source is equipped with a relief valve
set to open at the maximum relief pressure. See “Specifications” on
page 10.
4. Power down and depressurize the hydraulic power source.
5. Remove the plugs from the hydraulic power source ports.
6. Wipe the hydraulic power supply hose couplers with a clean, lint free
cloth.
7. Connect the hydraulic power source pressure hose to the supply “IN”
port.
8. Connect the hydraulic power source return hose to the supply “OUT”
port.
9. Ensure the hydraulic power supply couplers are undamaged, properly
connected and are tight.
10. Power up the hydraulic power source.
