3. 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 dam-
aged. 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 retract-
ed�
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 re-
tracted�
