ABOUT THIS MANUAL
The machine manual that you received with your
TENNANT machine contains valuable information
about the operation and maintenance, and numerous
sections filled with TENNANT part numbers for the
repair of the machine. Please read through this
section titled ABOUT THIS MANUAL to become
familiar with the contents of the machine manual,
making the information you are looking for easier to
find.
The machine manual consists of several sections of
reference information, and the remainder contain part
number information for ordering repair parts for the
machine. Each section has a shaded bar at the top of
the page with the name of that section. Just as this
section has the title ABOUT THIS MANUAL on the
top of each page. This way you can tell which section
you are in at all times.
REFERENCE SECTIONS
The reference information sections of the manual are;
General Information, Specifications, Operation,
Maintenance, and Appendix.
GENERAL INFORMATION -- The General
Information section of the manual contains the safety
precautions, the location of the safety labels on the
machine, and a table of contents of the entire manual.
The Safety Precautions are an overview of the safety
measures to be observed when operating and
maintaining your machine. The location of the safety
labels show the mounting location of the safety labels
for use in the replacement of the labels. The table of
contents in this section is a list of all the table of
contents that appear in the front of each section in the
manual. This can be used for easy reference to locate
information in a particular section of the manual.
SPECIFICATIONS -- The Specifications section of the
manual contains machine specification information
useful in the operation and maintenance of the
machine. This section gives you specification
information on the engine, electric motors, brake
system, hydraulics, fluid capacities, and machine
weight to mention a few. The section also has a
illustration of the top and side view of the machine
with the height and width dimensions displayed.
OPERATION -- The Operation section of the manual
contains information needed to operate the machine.
This section will list the controls and instruments on
the machine, overview the machine operation, and tell
you how to transport and store the machine.
MAINTENANCE -- The Maintenance section contains
information on the suggested maintenance
procedures and adjustments to keep your machine in
top operating condition. The section includes a
Maintenance Chart listing the maintenance schedule
and the areas of the machine to be addressed. Each
subject of maintenance is covered in more detail in
such areas as Lubrication, Hydraulics, Engine, and
Electrical System.
APPENDIX -- The Appendix contains hardware and
hydraulic information. Standard hardware torques and
identification information is included, plus hydraulic
torques if your machine is hydraulically controlled.
PART SECTIONS
The remaining sections of the manual contain part
number information for ordering repair parts for your
machine. The manual contains part number
information on every type of machine model available
in the model size of your particular machine.
Therefore there will be part number information in
your manual you will not need to refer to when
wanting to place an order.
The main thing you need to know about your machine
is what type of model is it. Is the machine powered by
an engine or batteries? If the machine has an engine,
is it fueled from gasoline, LPG, or gasoline? If it is a
mid-sized or larger sweeper, is it multi-level or low
dump? For the scrubbers, is it SRSror standard.
Determining this information about your machine will
help guide you through the separate parts sections to
find the repair part you need.

ABOUT THIS MANUAL
97 MM262 (3--91)
b
The smaller line of sweeper and scrubbers have less
complicated part section arrangement, and are easier
to find your way through the parts sections. The larger
machines can have quite a variety of model types
which significantly increases the size to the machine
manual. Because of this, on the larger machine we
made the first part section, Section 5, a part section
which contains parts common to all type of the
machine. If the machine has an engine, this section
contains parts information on a gasoline powered
machine.
The remaining sections contain only parts information
which is unique to that particular machine type, such
as unique diesel parts on the machine, or unique
SRSrparts. Knowing the machine model type you
have is important when searching for that part
information you need for ordering repair parts. Start in
that unique section first when looking for a part, then
go to the first parts section, Section 5, if the part can’t
be found in the unique section.
MACHINE SERIAL NUMBERS
When a design change takes place to a machine, the
changes are indicated in the parts sections with
machine serial numbers. Know the serial number of
your machine which can be found on the machine
data plate mounted on the machine. Record this
number on the inside front cover of your manual along
with your customer number.
Machine number usage is recorded in the Machine
Serial Number column of the parts lists in the parts
sections of the manual. If the machine serial number
column lists zeros on the left side of the dash, then
this part is used on all machines;
such as (000000-- ).
If the column lists zeros on the left of the dash and a
number on the right of the dash, then the part is used
on machines up to and including that machine serial
number; such as (00000--002345).
For parts that are used on machines beginning at and
continuing on from a certain serial number, the
column would list a serial number on the left of the
dash and have blank spaces on the right side of the
dash; such as (002346-- ). This part would be used
on machines starting with that machine serial number
and greater.
Finally, parts can be used on machines with serial
numbers in a certain block of numbers. In this
situation there is a serial number on the left and right
side of the dash. The part is then used on a machine
with a serial number starting at the number on the left
and up to and including the number on the right; such
as (002346--008900).
PARTS ASSEMBLIES
A part assembly has parts within the assembly, such
as a parking brake consisting of other smaller parts.
What parts are contained in a part assembly can be
determined by an indentation arrangement in the
description column of the parts lists.
Here is an example of a part assembly, in this case
we will use the parking brake mentioned previously:
Machine
Serial Number Description Qty.
(000000-- ) Parking Brake 1
(000000-- ) Pin, Roll 1
(000000-- ) Link 1
(000000-- ) Spring, Compression 1
(000000-- ) Pin, Roll 1
(000000-- ) Support 1
(000000-- ) Lever, Release 1
(000000-- ) Rod, Parking Brake 1
(000000-- ) Washer, 0.50” 3
In this example, the parts whose descriptions are
indented under the parking brake are all parts of the
parking brake. When you order the parking brake you
will receive all the parts listed under it. You also can
order any of the individual parts listed under the
parking brake if it is the only part you need.

SUPPLIER COMPONENT BREAKDOWNS
TENNANT purchases certain components of the
machine from suppliers. Some of these components
are engines, hydraulic pumps and motors, electric
motors, and solution pumps.
For those purchased components that are repairable,
lists of parts for them appear in the later part of the
parts sections. These are the supplier breakdowns.
The engine breakdown contains both supplier and
TENNANT parts numbers for repair parts.
Breakdowns for hydraulic and electrical components
have TENNANT part numbers for the parts
TENNANT supplies. The serial numbers listed in any
of the parts lists in these sections is a serial number
the manufacturer uses to identify design changes in
their particular component.
ORDERING REPAIR PARTS
Once you have located a part to order, there are
several things you need to have to place the order. At
the beginning of each parts section is an Ordering
Repair Parts page which lists the information you will
need to place your order. Review this list before
placing the order.
