Prior to Operation
We thank you for choosing a
Rhino®Powerpack.
Please note that the power-
pack is delivered without hy-
draulic oil, and therefore it
must be filled up with hydrau-
lic oil prior to operation.
To ensure smooth operation
and long-lasting performance
of your new powerpack, we
recommend that you study
this operating manual carefully
and pay special attention to
the
Safety and Service
Precautions
We hope you will be satisfied
with your new Rhino®
Hydraulic Power Pack.
Best regards

Safety Precautions
1. Always use protective earplugs. The powerpack complies with the EU noise limits, but by
daily long-lasting operation there is a risk of hearing defects.
2. Always connect hoses before starting.
3. Never add fuel and oil when the engine is running.
4. In case of non-operation or performance, always turn off the engine.
5. Never start the engine without side covers.
6. Operation of the powerpack without tool connected and with lever at “ON” (“on” is indicated
by “5”, “8” or “10” setting) may cause overheating of the system and damage to the
powerpack.
7. When lifting the powerpack from a vehicle, we recommend the use of a crane.
8. The pressure relief valve is set at 2300 psi (160) bar from our plant. Never set it higher.
9. Always use filters with by-pass. The use of filters without by-pass may damage the hydraulic
hoses and the filter cover.
Filling Up Hydraulic Oil
•To fill up with hydraulic oil, loosen the
filter cover on top of the powerpack.
•Remove the filter element (see photo),
and fill up with oil. When oil is showing
at the bottom of the filter unit, there is
enough oil on the powerpack.
•Insert the filter element again, mount
the cover and the powerpack is ready
for use.
Please note: When connecting new extension
hoses, it is necessary to fill up with extra 1/2 gal.
(2 litres) of oil. Therefore always top up the
powerpack when connecting new extension hoses.

Technical Data
Hydraulics
The Rhino®HPP18V FLEX open center hydraulic powerpack is designed in accordance with the
EHTMA categories C, D and E, which prescribe a minimum performance of 5 g.p.m., 8 g.p.m.
and 10 g.p.m. (20 l.p.m., 30 l.p.m. and 40 l.p.m.) respectively at 2000 psi (138 bar).
The powerpack is designed with a pressure relief valve to avoid too high a pressure.
Furthermore, the very efficient air cooling protects the powerpack against overheating. The
powerpack has no POR (Power On Request) system, and the engine r.p.m. (oil supply) must be
adjusted manually by means of the throttle.
Oil flow 5 g.p.m. (20 l.p.m.) at 1800 r.p.m.
8 g.p.m. (30 l.p.m.) at 2700 r.p.m.
10 g.p.m. (40 l.p.m.) at 3600 r.p.m.
Working pressure nominal 1750 psi (120 bar)
Pressure relief valve Set at 2300 psi (160 bar)
Pump Gear pump
Oil temperature Max. 160°F (70°C)
Hydraulic oil tank capacity Min. 2.1 gal (8 litres)
Max. 2.9 gal (11 litres)
Petrol tank capacity 2.2 gal (8.5 litres)
Hydraulic system compl. 3.2 gal (12 litres)
Filter system (filter element) 25 Micron with by-pass
Engine Vanguard 2-cylinder
18 HP (gross power)
4-stroke gas
Gas - normal or unleaded
Engine oil 0.3 gal (1.1 litres)
Guaranteed sound power level LWA 101 dB
Sound pressure level 1 m LPA 89 dB
Dimensions (LxWxH) 31-5/8”x24-5/8”x27-3/8”
(805x625x695 mm)
Weight, without hydraulic oil 232 lbs (105 kg)

Starting Instructions
Please observe the starting instructions on the front of the
powerpack.
Start: •Check engine oil level
•Check hydraulic oil level at sight glass
•Connect hoses and tool
•Switch fuel tap to “ON”
•Activate choke
•Turn ignition switch
•Activate electric start or pull recoil starter
•Set the lever at the desired oil flow
5/8/10 g.p.m. (20/30/40 l.p.m.) - see below
Stop: •Move the lever to “OFF“
•Turn off the ignition switch
•Turn the fuel tap to “OFF”

The desired oil flow can be set on the front of the powerpack. A
marking is engraved in the lever.
To set the flow at 5, 8 or 10 g.p.m. (20, 30 or 40 l.p.m.), the
lever must be turned to the right until the marking is opposite
the required flow.
The pressure relief valve setting will be the same on all flows.

Hydraulic Settings
Check the working pressure by means of test equipment. The test equipment must comprise a
pressure gauge, a flow meter and a valve for adjustment of pressure.
The pressure relief valve is placed on the right side of the valve block.
1. Connect the test equipment, start the powerpack and move the lever to “ON” (“on” is
indicated by “5”, “8” or “10” setting). Then close the valve on the test equipment - the
pressure gauge must show 2300 psi (160 bar).
Adjust the pressure relief valve by loosening the lock nut and turning the adjustment screw
in or out. “In” increases the pressure, and “out” decreases the pressure.
Retighten the lock nut after adjustment.
2. When the pressure relief valve has been adjusted correctly, the working pressure must be
set at 1450 psi (100 bar) by means of the valve on the test equipment. At 1450 psi (100
bar) the oil flow should correspond to the flow rate the lever is set at (see Setting of Flow).
Oil Types
The Rhino®powerpack uses standard hydraulic oil, i.e. all types of mineral oil and
biodegradable oil, which comply with the following values:
Recommended viscosity
ISO 32 (20-40 cSt)
Permitted viscosity
ISO 15-1000 (15-1000 cSt)
Viscosity index
Min. 100
Temperature area
-70°F to 160°F (-57°C to 71°C)
If correct pressure/oil flow cannot be achieved by following the
above instructions, the powerpack must be re-adjusted. If the
pressure/oil flow is then still incorrect, the pump is defect and
must be replaced.
