Installation (Continued)
NOTE: Be sure adequate cooling for the hydraulic oil is
provided. Excessive temperatures can cause damage to
oil and/or system components. Cooling of oil is espe-
cially important on systems where continuous operation
is required. Cooling requirements must be based on:
duty cycle, pressure/flow, ambient temperatures, oil and
component maximum temperature specifications, and
reservoir capacity. Systems operating at excessively high
temperatures can be hazardous and may cause property
damage and/or personal injury.
NOTE: When the ambient temperature is below 32°F,
allow the pump to operate unloaded for several minutes
to warm the oil in the reservoir.
Operation
1. At initial start-up, start and stop several times (jog) to
allow the assembly to prime. After lines are full, the
pump may be operated at full speed.
2. Bleed all air from hydraulic system to prevent erratic
operation.
3. Recheck reservoir oil level after a few complete cycles
of the hydraulic system and refill if necessary.
Fluid Motor Operation
1. The reason for the high pressure oil seal and seal
check valves in the fluid motor is to provide bidi-
rectional rotation without adding an independent
drain line from the oil seal chamber. However, if you
plan to operate the fluid motor(s) in series with other
equipment or with "down stream" (outlet) pressure

exceeding 400 PSI, then the case drain port must
be utilized. The case drain feature can be used by
removing the steel 7/16-20 SAE O-ring plug (see
Specification drawing) and plumbing this port back
to "tank" (low pressure line returning to reservoir).
BE SURE TO DISCONNECT POWER AND RELEASE
ALL SYSTEM PRESSURE BEFORE SERVICING THIS
EQUIPMENT.
1. Keep the reservoir filled with hydraulic fluid.
Recommended Hydraulic Fluids: use a good grade of
automatic transmission fluid (ATF).
2. Make frequent inspection of hydraulic fluid and
change if contaminated.
3. To fill the reservoir with clean oil:
Use a clean funnel fitted with a fine mesh wire screen.
Do not use a cloth strainer. Most pump/fluid motor
failure, valve malfunctions, and short unit life can
be traced directly or indirectly to dirt or other for-
eign material (water, chips, lint, etc.) getting into, or
already in, the hydraulic system.
4. Keep the unit clean of dirt and foreign materials.
5. Keep electrical connections clean.
