HYDRAULICS
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:
Tennant
True
premium
hydraulic fluid (Extended Life)

ISO Grade
Capacity
1057707

3.8 L (1 gal)

19 L (5 gal)
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. The reservoir holds up to 2 qt (1.9 L) of
hydraulic fluid. The reservoir is mounted on top of
the hydraulic pump.
Check the hydraulic fluid level after every 50
hours of operation. The fluid level should be 0.5 to
1 in (15 to 25 mm) from the top of the reservoir.
Do not overfill the hydraulic reservoir. The
hydraulic fluid expands as it heats to its normal
operating temperature. Always allow for
expansion when filling the reservoir.
ATTENTION! Do not overfill the
hydraulic fluid reservoir or operate the
machine with a low level of hydraulic
fluid in the reservoir. Damage to the
machine hydraulic system may result.
Drain and refill the hydraulic fluid reservoir with
new
Tennant
True
premium hydraulic fluid after
every 2400 hours of operation. Machines have a
blue colored drop (left photo) on the hydraulic fluid
label if originally equipped with
Tennant
True
premium hydraulic fluid.

NOTE: Change the hydraulic fluid and filter, after
every 800 hours for ALL machines that have NOT
consistently used
