PREVENTIVE MAINTENANCE -CONTINUED
Hydraulic Fluid Level
WARNING: Cylinder(s) must be fully retracted before checking the fluid level. Release all system
pressure before breaking any hydraulic connection in the system.
Check the hydraulic fluid level in the reservoir periodically. Use a funnel with a filter to add hydraulic fluid if needed.
Refer to Table 1 for your reservoir type.
For models with Reservoir Type A:
Place the pump in a vertical position with the pump head facing upward.
Unscrew and remove the pump head from the reservoir. The fluid level within the reservoir should come to the
fluid level mark indicated on the reservoir body decal. Before replacing the pump head, visually inspect the o-ring
which seals the pump head/reservoir assembly. Replace this o-ring if it is worn or damaged. Reinstall pump head
to reservoir and tighten securely. Check for leaks.
For models with Reservoir Type B:
Remove the filler cap. The
fluid level should come to the bottom edge of the filler hole when
the pump is level and resting horizontally on its base and the
cylinders are retracted (see Figure 2).
For models with Reservoir Type C
: Remove the filler cap. The
fluid level should be 1/2 inch (12.7 mm) from the filler hole when
the pump is level and resting horizontally on its base and the
cylinders are retracted.
IMPORTANT: The pump sight gauge indicates the presence of
hydraulic fluid only. It does not determine correct fluid level.
For models with Reservoir Type D
: Remove the filler cap. The
fluid level should be 1/2 inch (12.7 mm) from the cover plate when
the pump is level and resting horizontally on its base and the
cylinders are retracted.
Draining And Flushing The Reservoir
Drain, clean and replenish the reservoir with high-grade, approved Power Team hydraulic fluid yearly or more often if
necessary. The frequency of fluid change will depend upon the general working conditions, severity of use and
overall cleanliness and care given the pump.
IMPORTANT: Clean the exterior of the pump first. After draining and flushing the reservoir, drain and clean
the other hydraulic system components (hoses, cylinders, etc.) before connecting them to the pump again.
This will help prevent contaminated fluid from entering the pump.
Refer to Table 1 for your reservoir type.
For models with Reservoir Type A:
1. Unthread and separate the pump head from the reservoir. Drain the reservoir of the used hydraulic fluid.
2. Flush out reservoir with a small amount of clean hydraulic fluid. Clean the pump intake filter.
IMPORTANT: Removing the filter from the pump assembly could result in its breakage. Attempt to clean it
as well as possible with it installed.
3. Refill the reservoir and reassemble the pump head to the reservoir. Tighten securely. Check for leaks.
For models with Reservoir Type B & C:
1. Remove the filler cap. Drain the hydraulic fluid through filler hole.
2. Remove the nut from the tie rod. Separate the reservoir from the pump body. Clean the reservoir and filter.
IMPORTANT: Removing the filter from the pump assembly could result in its breakage. Attempt to clean it
as well as possible with it installed.
3. Reassemble and fill the reservoir with Power Team hydraulic fluid. Replace the filler cap.
For models with Reservoir Type D:
1. Remove the ten screws fastening the reservoir cover to the reservoir, and lift the pump and valve assemblies off.
2. Drain all hydraulic fluid and flush reservoir with a small amount of clean hydraulic fluid.
3. Remove the pump assembly filter, rinse it clean, and reassemble.
4. Refill the reservoir with Power Team hydraulic fluid. Place the pump and
valve assembly (with gasket) on the reservoir, and thread the ten screws.
Tighten securely and evenly.
