HYDRAULICS
HYDRAULIC FLUID
Hydraulic fluid drives most of the moving
components of the machine. The quality and
condition of the hydraulic fluid play a very important
role in how well the machine operates. Tennant
Company has developed its own hydraulic fluid to
meet the special needs of its machines.
TENNANT Hydraulic Fluid is a specially compounded
oil with the following features not found in many
hydraulic fluids:
1. Flat viscosity curve.
2. Additives to prevent corrosion.
3. Additives to prevent oxidation.
4. Rust inhibitors.
5. Foam suppressors.
These features restrict foaming of the hydraulic fluid
and provide a high standard of lubrication to the
components.

TENNANT Hydraulic Fluids have a very flat viscosity
curve (synonymous with “high viscosity index”). The
flat viscosity curve means that the thickness of the
fluid is very constant over wide temperature ranges.
Hydraulic fluid with the viscosity rating of 10W40
should be used in machines that are operated in
areas which have ambient temperatures up to 90
_
(32
_
C). Use the 20W60 rated hydraulic fluid in areas
which have ambient temperatures above 90
_
(32
_
C).
ATTENTION! If a locally--available hydraulic fluid
is preferred, or if products of only one oil
company are used, the hydraulic fluid used must
match closely the viscosity specifications given in
the chart for TENNANT Hydraulic Fluid, as well as
the other features described. Do not substitute
automatic transmission fluid for hydraulic fluid.
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 12 gal
(45.5 L) of hydraulic fluid. The reservoir is located
behind the operator seat.
The reservoir is equipped with a breather---filler cap
and a sight gauge. The breather---filler cap requires
no regular maintenance.
The reservoir is also equipped with a fluid level sight
gauge. It is located on the side of the hydraulic fluid
reservoir. The sight gauge indicates the level of
hydraulic fluid in the reservoir. Check the hydraulic
fluid level after every 100 hours of operation.

A. Hydraulic Fluid Reservoir
B. Sight Gauge
Do not overfill the hydraulic fluid reservoir. When
the fluid is cold, the fluid should just appear on the
bottom of the sight gauge. The hydraulic fluid
expands as it heats up to its normal operating
temperature. Always allow for this expansion when
filling the hydraulic fluid reservoir.
ATTENTION! Do not overfill the hydraulic fluid
reservoir or operate the machine with a low level
of hydraulic fluid in the reservoir. Either one may
cause damage to the machine hydraulic system.
Change the hydraulic fluid after every 400 hours of
operation.
