Preventive Maintenance - SPX POWER TEAM P19L Serie Instrucciones De Funcionamiento

Operating Instructions, Form No. 1000134, Back sheet 2 of 4
The P19L and P59L hand pumps can be operated in a horizontal position or in a vertical position with head pointing
downward.
IMPORTANT: Figure 1 illustrates
the normal drop of handle effort
experienced when two-stage
pumps shift from low pressure
stage to high pressure stage.
Two-way Valve
Pumps with a two-way valve are for use
with single-acting cylinders.
1. To extend the cylinder, turn the
valve knob counterclockwise to a
closed (seated) position. Note:
Hand tight only! Work the pump
handle up and down to build
pressure.
2. To release pressure, open the valve
slowly by turning the knob clockwise to control the load.
WARNING: The operator should always release the pressure slowly.
IMPORTANT: Any repair or servicing that requires dismantling the pump must be performed in a dirt-free
environment by a qualified technician.
Lubrication
Apply lubricant regularly to all pivot and rubbing points.
Use a good grade of No. 10 motor oil or grease. Do not use dry lubricants.
Bleeding Air From the System
Air can accumulate in the hydraulic system during the initial set-up or after prolonged use, causing the cylinder to
respond slowly or in an unstable manner. To remove the air:
1. Position the cylinder at a lower level than the pump, and turn the cylinder rod end down.
2. Extend and retract the cylinder several times without putting a load on the system. Air will be released into the
pump reservoir. Follow the fluid level instructions for your reservoir type to release the air from the reservoir and
top off the fluid supply.
Bleeding Air From The Pump
When the pump is first put into use, or after refilling the pump's reservoir it may be necessary to bleed any trapped air
from the pump. If this is not done the pump will not function properly (will not build pressure or has very spongy
operation).
To bleed air from the pump, turn the pressure control knob counterclockwise (CCW) (open position) and operate the
pump handle up and down approximately twenty times. Turn the pressure control knob clockwise (CW) (closed
position) to its full stop position. The pump should now be bled of air and ready to use.
