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 part no.

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. The reservoir holds 5 gal (19 L) of hydraulic
fluid. The reservoir is located to the left of the
operator seat.
A breather-filler cap and fluid level dipstick is
mounted on top of the reservoir. The breather
relieves excess pressure in the reservoir. The
breather should be replaced after every 800 hours of
operation.

RESERVOIR BREATHER-FILLER CAP
A. Breather-Filler Cap
B. Hydraulic Fluid Reservoir
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. The hopper must
be lowered when checking reservoir fluid level.
Check the hydraulic fluid level after every 100 hours
of operation. It should be above the “ADD” marks on
the dipstick, but not above the “FULL” mark when the
hydraulic fluid is warm.
