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
SRSr or 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

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 SRSr parts. 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---
).
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
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).
b
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.

Go To..
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.
