Bleeding the Air from the System
Air can accumulate in the hydraulic system. This air causes the tool to respond in an unstable or slow
1. Position hydraulic tool(s) on their sides with the couplers located upward and at a lower level than the
pump.
2. Remove any load from the tool(s), and cycle the hydraulic system through several cycles (fully extend and
retract the tools).
3. The bladder must be vented and refilled (see section “Filling the Bladder”).
Checking Hydraulic Fluid and Filling the Bladder
1. Check the oil level in the bladder after each 10 hours of use. With all cylinders retracted and the pump in
the upright (or vertical) position, the oil level should be at the top of the filler hole.
2. When adding oil, use Power Team approved, high-grade hydraulic oil (215 SSU @ 100° F). Retract the
cylinders and disconnect the power supply. Clean the area around the filter plug, remove the plug, and
insert a clean funnel with filter.
3. The frequency of oil changes will depend upon the general working conditions, severity of use, and
overall cleanliness and care given the pump. Three hundred hours of use under general shop conditions
is considered a standard change interval. Drain, flush, and refill the bladder with Power Team approved,
high-grade hydraulic oil (215 SSU @ 100° F).
4. Replace filler cap.
Important:
Tighten filler cap 1/2 - 1 turn after o-ring contacts sealing surface. Overtightening can
cause pump damage.
Note:
For more complete instructions, reference
“Checking Hydraulic Fluid and Filling the Bladder”
under Set-up Instructions.
Maintenance and Cleaning
1. Keep the pump’s outer surface as free from dirt as possible.
2. Seal all unused couplers with thread protectors.
3. Keep all hose connections free of dirt and grime.
4. Equipment connected to the pump must be kept clean.
5. Use only Power Team approved, high-grade hydraulic oil in this pump. Change as recommended
(approx. every 300 hours).
Draining And Cleaning The Bladder
IMPORTANT:
Clean the area around the filler hole to prevent contamination of the hydraulic fluid.
A. Remove the filler plug and drain hydraulic fluid completely.
B. Fill bladder half full with clean hydraulic fluid. Flush bladder with clean fluid and drain.
IMPORTANT:
Never use solvents to clean the bladder! Never disassemble the bladder from the pump!
C. Fill the bladder completely full with clean approved Power Team hydraulic fluid.
