Preventive Maintenance Continued
5. Draining and Flushing the Reservoir
IMPORTANT: Clean the pump exterior before the
pump interior is removed from the reservoir.
A� Remove the ten screws fastening the motor and
pump assembly to the reservoir�
IMPORTANT: Do not damage the gasket
or bump the filter or pressure regulating
valves when lifting the pump and motor off
the reservoir. See Figure 6.
B� Clean the inside of the reservoir, and fill with a
suitable Power Team hydraulic fluid. Rinse the
filter clean�
C� Place the pump and motor assembly back onto
the reservoir, and secure with two machine
screws assembled on opposite corners of the
cover plate�
IMPORTANT: The hydraulic flow control valve must be in the neutral position for the following step. If
the pump is equipped with a valve that has only an advance or retract position, place the valve in the
advance position, and connect a hose to the advance port on the valve. Place the other end of the hose
into the oil filler plug
hole.
D� Run the pump for several minutes� Then disconnect the motor and pump assembly, and drain and
clean the inside of the reservoir�
E� Fill the reservoir with an approved, high-grade hydraulic oil. Place the pump and motor assembly (with
gasket) on the reservoir, and thread the ten screws. Tighten securely and evenly.
6. Adding Hydraulic Fluid to the Reservoir
A� Wrench must be fully retracted and the power supply disconnected when adding oil to the reservoir.
B� Clean the entire area around the filler plug before removing the filler plug�
C� Use a clean funnel with filter when adding oil.
D� Use an approved, high-grade hydraulic oil (215 SSU @ 100° F) only�
7. Sound Reduction
The electrically powered hydraulic pump operates in the 90-95 dBA range. If further sound reduction is
desired, any of the following options will help reduce the sound level.
A� Install a pressure switch to automatically shut off the motor when maximum pressure is reached
(holding cycle)�
B� Use a 3450 RPM, 1-1/2 horsepower, 115 VAC, 60 Hz, 1-phase pumping unit.
C� Use a 3450 RPM, 1-1/2 horsepower, 230 VAC, 60 Hz, 3-phase pumping unit.
D� Install casters (two gallon reservoir only) to reduce the noise level.
