Hydraulic Fluid:
Hydraulic fluid selection & regular fluid
inspection is very important to increase the
life of your hydraulic system. The function of
Hydraulic fluid is to transfer power from the
gear pump to the actuator, weather it is a
hydraulic motor o Cylinder.
Selecting the proper fluid viscosity is very
important. Selecting a fluid that is to thin
may not lubricate the gear pump properly;
causing premature pump failure. Also
selecting a fluid that is too thick will induce
load & cause power loss or cavitation
causing gear pump failure.
ISO viscosity grades 22 to 46 are
recommended. Anti wear, antifoaming & rust
inhibitor additives are recommended.
For colder climates ATF can be used
In extreme cases Mil-5606 fluid can be used
Do not use synthetic, biodegradable or water
base hydraulic fluids. In most cases these
fluids are not compatible with Buna O-rings.
Please check fluid compatibility before use.
Tractor hydraulic fluid is not recommended.
Most tractor hydraulic fluid has to high of a
viscosity & may not be compatible with Buna
O-rings.
Recommended Fluid Viscosity
Specifications:
ISO Viscosity Grades 22-46
cSt @ 40°C 22-46
cSt @ 100°C 4-8
Recommended Fluid Maintenance:
 Change hydraulic fluid after initial
100 hours of operation
 Change hydraulic fluid every 3000
hours or 2 years there after
 Check hydraulic fluid level regularly
before operation
Maintenance:
 Change hydraulic fluid after initial 100
hours of operation
 Change hydraulic fluid every 3000 hours or
2 years there after
 Check hydraulic fluid level regularly before
operation
 Recommended fluids
 Check electrical connections regularly
 Corrosion on all connectors
 Battery cables
 Load test battery often before use
 Cleaning
 Never pressure wash or hose down
the power unit. The DC motor is not
sealed extended exposure to moisture
will cause premature motor failure.
 Spray light amounts of
cleaner/degreaser on unit and dry with
compressed air and/or rag.
 Cleaning reservoir breather cap
Remove red cap from breather cap and clean
filter element with dishwashing soap & water.
Make sure the filter element is completely dry
before installing back in the breather cap
Installation
:
1. Location
 Power unit should be mounted either in an
enclosure or a location preventing the unit
from being exposed moisture and weather.
 Units with Poly reservoirs should never be
mounted in a location where the reservoir
is exposed to direct sunlight.-
 Mount unit as close to the battery as
possible.
