Always store an idle hydraulic motor generator in a
clean dry space, safe from damage or pilferage.
Do not exceed the rated electrical load limits or use the
hydraulic motor generator for applications beyond its
Protect the hydraulic motor generator from extremely
dusty or wet conditions.
Always keep critical hydraulic motor generator
markings, such as lables and warning stickers legible.
Always replace hoses, couplings and other parts with
replacement parts as identified in this manual's parts
listing. Supply hoses must have a minimum working
pressure rating of 2500 psi/175 bar.
Permit only experienced personnel to perform hydraulic
motor generator repairs.
Be sure to wipe all couplers clean before connecting.
Use only lint-free cloths.
The hydraulic circuit control valve must be in the 'OFF"
position when coupling or uncoupling the hydraulic motor
generator. Failure to do so may result in damage to the
quick couplers and cause overheating of the hydraulic
The hydraulic motor generator should be up to
operating speed before connecting and applying power
to the electrical load.
For continuous operation, do not exceed the rated
output power of 3500W.
Do not exceed the current rating specified for the
electrical outlet in use.
Check fastener tightness often and before each use
The hydraulic system should provide a flow of 79
gpm/26-34 Ipm at an operating pressure of 10002000
psi/70-140 bar. Recommended relief valve setting is
2100 psi/145 bar.
The system should have no more than 250 psi/ 17 bar
backpressure measured at the tool end of the operating
hoses. The system conditions for measurement are at
maximum fluid viscosity of 400 ssu/82 centistokes
(minimum operating temperatures).
The hydraulic system should have enough heat
rejection capacity to limit the maximum oil temperature to
temperature. The recommended minimum cooling
capacity is 5 hp/3.73 kW at a 400 F/ 220C difference
between ambient temperature and oil temperature.
The hydraulic system should have a minimum of 25
micron filtration. Recommend using filter elements sized
for a flow of at least 30 gpm/114 Ipm for cold
temperature startup and maximum dirt holding capacity.
The hydraulic fluid used should have a viscosity
between 100 and 400 ssu/20 and 82 centistokes at the
temperatures. Petroleum base hydraulic fluids with
antiwear properties and a viscosity index over 140
The recommended hose size is .500 inch/12 mm I.D.
up to 50 ft/15 m long and .625 inch/16 mm l.D.
minimum up to 100 ft/30 m long.
