HYDRAULIC FLUID
The quality and condition of the hydraulic fluid
plays a very important role in how well the
machine operates. TENNANT’s hydraulic fluid is
designed to meet the special needs of its
machines.
TENNANT’s hydraulic fluids provide longer life of
the hydraulic components. There are two fluids
available for two different temperature ranges:

The higher temperature fluid is designed with a
higher viscosity and should not be used at the
lower temperatures. Possible damage to the
hydraulic pumps may occur because of improper
lubrication.
The lower temperature fluid is a thinner fluid
designed for colder temperatures.
If a locally-available hydraulic fluid is preferred, or
if products of only one oil company are used,
contact TENNANT Technical Customer Service to
check the specifications of the substitute fluid.
Using substitute fluids can cause premature
failure of hydraulic components.
ATTENTION! Hydraulic components
depend on system hydraulic fluid for
internal lubrication. If dirt or other
contaminants are allowed to enter the
hydraulic system, malfunctions,
accelerated wear, and damage will
result.
HYDRAULIC FLUID RESERVOIR
Hydraulic fluid is stored in the hydraulic fluid
reservoir. (For machines below serial number
007006) the reservoir holds up to 11.5 gal
(44 L) of hydraulic fluid. (For machines serial
number 007006 and above) the reservoir holds up
to 14.2 gal (54 L) of hydraulic fluid. The reservoir
is located in the front left corner of the machine.
The reservoir is equipped with a breather-filler cap
and fluid level dipstick mounted on the filler neck.
See Hydraulic Fluid Reservoir Breather for
breather service information.

The hydraulic fluid level dipstick is built into the
breather-filler cap. The end of the dipstick is
marked with “full” and “add” levels. This indicates
the level of hydraulic fluid in the reservoir.
