HYDRAULICS
HYDRAULIC FLUID
The quality and condition of the hydraulic fluid
play a very important role in how well the machine
operates. TENNANT’s hydraulic fluid is specially
selected to meet the needs of TENNANT
machines.
TENNANT’s hydraulic fluids provide a longer life
for the hydraulic components. There is one
recommended fluid.
TENNANT part no. Fluid Weight

If a locally-available hydraulic fluid is used, make
sure the specifications match TENNANT hydraulic
fluid specifications. Using substitute fluids can
cause premature failure of hydraulic components.
European marketed machines are filled with
locally available hydraulic fluids. Check the label
on the hydraulic fluid reservoir.
ATTENTION! Hydraulic components depend
on system hydraulic fluid for internal
lubrication. Malfunctions, accelerated wear,
and damage will result if dirt or other
contaminants enter the hydraulic system.
HYDRAULIC FLUID RESERVOIR
Hydraulic fluid is stored in the hydraulic fluid
reservoir. It holds 1 gal (3.8 L) of hydraulic fluid.
The reservoir is mounted on the back of the
hydraulic pump.
The fluid level is checked by opening the fill cap
with the hopper in the sweeping position. The
reservoir is full when the fluid level is between the
marks on the dipstick.

Check the hydraulic fluid level after every
100 hours of operation. Change the hydraulic fluid
after every 400 hours of operation. To remove the
hydraulic fluid, insert a hand suction device
through the fill opening. Do not overfill the
hydraulic fluid reservoir. Hydraulic fluid expands
as it heats to its normal operating temperature.
Always allow for expansion when filling the
reservoir.
