BRUSH I NFO RMATION

For best results, use the correct brush type for the
cleaning application.

NOTE: The amount and type of soilage play an
important role in determining the type of brushes
to use. Contact an authorized service
representative for specific recommendations.

Polypropylene Brush -- Best overall general
cleaning brush. The bristles fan out and dig into
cracks to remove debris.

Polypropylene and Wire Brush -­Recommended for moving heavy debris. Best
bristle mix for moving large quantities of sand and
heavier debris. The bristles fan out similar to the
polypropylene brush. The wire bristles provide the
ability to move heavier material.

PET (Polyethylene Terephthalate) Heavy Duty
Brush -- Recommended for areas where there is

a heavy build up of debris. The stiffer / thicker
bristles provide more aggressive digging action to
remove compacted debris from along buildings,
curbs, and in corners.

HOW THE MACHI NE WORKS

The two front brushes move debris to the center
of the machine and the vacuum pulls the debris
into the hopper. The airflow must be maintained
through the machine to keep it functioning
properly.

The air and debris swirl in a cyclonic rotation
inside the hopper. The dust and debris drops to
the bottom of the hopper and the air exits through
vents at the rear of the machine. Screens located
in the hopper prevent light debris (leaves, paper,
etc...) from exiting the hopper and the cyclone
assemblies located at the top of the hopper
prevent dust particles from exiting the hopper.

TURNING OF F THE MACHINE

1. Stop the machine, turn off all sweeping
functions, and place the drive lever into the
neutral (middle) position.

2. Wait several seconds for the vacuum fan to
completely stop rotating.

NOTE: If the engine is turned off before the
vacuum fan stops rotating, the vacuum fan brake
will engage and emit a very loud noise as it stops
the fan.

3. Turn the ignition switch key counter clockwise
to turn off the machine. Remain in the
operator seat until the engine is off.

FOR SAFETY: Before leaving or servicing
machine, stop on level surface, place the
drive lever in neutral, set parking brake, turn
off machine, and remove key from ignition.

WHILE O PE RATING THE MACHI NE

Perform the Pre--Operation Procedures before
each use (see MACHINE MAINTENANCE section
of this manual).

Avoid bulky debris such as crates, boxes, tree
branches, and heavy material. Avoid straps,
twine, rope, etc., that could become entangled in
the brushes.

Plan the sweeping in advance. Try to arrange long
runs with minimum stopping and starting. Sweep
as straight a path as possible. Overlap the brush
paths. Use dust suppression in dusty conditions.

Avoid turning the steering wheel too sharply when
the machine is in motion. The machine is very
responsive to the movement of the steering
wheel. Avoid sudden turns, except in
emergencies.

If poor sweeping performance is observed, stop
cleaning and refer to MACHINE
TROUBLESHOOTING section of this manual.

Drive the machine slowly on inclines. Use the
brake pedal to control machine speed on
descending inclines. Sweep with the machine up
inclines rather than down inclines.

Never maneuver over curbs with the brushes and
nozzle down. Always raise the brushes and
nozzle prior to moving over curbs. Never drive
over curbs at a high speed or at a 90_angle.
Approach curbs at approximately a 45_ angle.

In rare circumstances one wheel may lose traction
when moving over curbs due to uneven weight
distribution. The machine automatically provides
traction to prevent the vehicle from coming to a
stop due to one wheel losing traction when the
machine is in work mode 2.

FOR SAFETY: When using machine, go slow
on inclines and slippery surfaces.

Maximum rated climb and descent for a full
hopper is 9_/20%.

HYDRAULICS

Check the hydraulic fluid level daily. The hopper
must be down and the machine at operating
temperature before checking the hydraulic fluid
level.

ATTENTION! Do not overfill the hydraulic fluid
reservoir or operate the machine with a low
level of hydraulic fluid in the reservoir.
Damage to the machine hydraulic system may
result.

Check the hydraulic pressure filter indicator after
every 250 hours of operation. The machine must
be running in order to get an accurate reading
from this indicator.

Replace the auxiliary hydraulic pressure filter after
every 2000 hours of operation or if the pressure
filter indicator arrow is in the yellow/red area of
the indicator with the engine running. The filter is
useable when the indicator arrow is in the green
area of the indicator.

Apply a light film of hydraulic fluid onto the filler
cap gasket before reinstalling the cap onto the
reservoir.

Replace the hydraulic return line filter after every
2000 hours of operation.

Replace the auxiliary and steering pump hydraulic
strainers after every 2000 hours of operation.

Drain and refill the hydraulic fluid reservoir with
new hydraulic fluid after every 2000 hours of
operation.

HYDRAULIC HOSES

Check the hydraulic hoses after every 250 hours
of operation for wear, damage, and leaks.

HYDRAULIC FLUID

Machines use two different type of hydraulic fluids
depending on where the machine was built.
Mixing the fluids is not recommended. Identify
the machine build location by the data plate.

European data plate

European built machines use Turbo Diesel Engine
Oil, 15W40 API CF4/ACEA2.

FOR SAFETY: When servicing machine, use
cardboard to locate leaking hydraulic fluid
under pressure.

High pressure fluid escaping from a very small
hole can almost be invisible, and can cause injury.

Contact appropriate personnel if a leak is
discovered.

A TTENTION: Only use TENNANT supplied
hydraulic hoses or equivalent rated hydraulic
hoses.

USA data plate

USA built machines: There are two fluids
available for different temperature ranges:

TennantTrue premium

hydraulic fluid (Extended Life)

Part
number

1057710 above 7_ C(45_ F) 100 3.8 L

105771 1 above 7_ C(45_ F) 100 19 L

1057707 below 7_ C(45_ F) 32 3.8 L

1057708 below 7_ C(45_ F) 32 19 L

If using a locally--available hydraulic fluid, be sure
the specifications match the Tennant hydraulic
fluid specifications. Substitute fluids can cause
premature failure of hydraulic components.

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.

ENGINE OIL

Check the engine oil level daily. Change the oil
and filter after every 250 hours of operation.

Fill the engine with oil until the oil is between the
indicator marks on the dipstick. DO NOT fill past
the top indicator mark. The engine oil capacity is
6 L (6.35 qt) with oil filter.

Check the condition of the radiator and radiator
screen after every 250 hours of operation.

COOLING SYSTEM

FOR SAFETY: When servicing machine, avoid
contact with hot engine coolant.

Check the coolant level in the reservoir daily. The
coolant level must be between the two indicator
marks when the engine is cold.

FOR SAFETY: When servicing machine, do
not remove cap from radiator when engine is
hot. Allow engine to cool.

Check the coolant mixture every 750 hours of
operation.

Flush the radiator and the cooling system after
every 2000 hours of operation.

ENGINE BELT

Check the belt tension after every 750 hours of
operation. Adjust tension as necessary . Proper
belt tension is 7 mm to 9 mm (0.28 to 0.35 in).

FUEL FILTERS

Replace the fuel filter after every 750 hours of
operation. To avoid extensive bleeding of the fuel
system when replacing the fuel filter, fill the new
filter with as much diesel fuel as possible before
installing the filter.

FOR SAFETY: When servicing machine, keep
flames and sparks away from fuel system
service area. Keep area well ventilated.

On machines below serial number 002135,
replace the inline fuel filter after every 750 hours
of operation.

FUEL LINES

Check the fuel lines every 50 hours of operation.
If the clamp band is loose, apply oil to the screw
of the band and securely tighten the band.

The rubber fuel lines can become worn--out
whether the engine has been used much or not.
Replace the fuel lines and clamp bands every two
years.

FOR SAFETY: When servicing machine, keep
flames and sparks away from fuel system
service area. Keep area well ventilated.

If the fuel lines and clamp bands are worn or
damaged before two years time; replace or repair
them at once. Bleed the fuel system after
replacement of any fuel lines, see PRIMING THE
FUEL SYSTEM. When the fuel lines are not
installed, plug both ends with clean cloth or paper
to prevent dirt from entering the lines. Dirt in the
lines can cause fuel injection pump malfunction.

60

PRIMING THE F UEL SYSTEM

Typical diesel fuel systems require priming to
remove pockets of air from the fuel lines and fuel
components. This is usually required after running
out of fuel, changing fuel filter elements or
repairing a fuel system component. Air in the fuel
prevents smooth engine operation.

This fuel system however is self-priming. The
return line comes from the top of the injector that
allows the air to escape through the return line.

VALVE CLEARANCES

Check and adjust the valve clearances after every
2000 hours of operation.

636 9006280 (1-- 10)

BATTERY

Home

Find...

Go To..

Check the electrolyte level in non--sealed batteries
after every 250 hours of operation. Never add
acid to the batteries. Add distilled water only.
Always keep the battery caps on, except when
adding water or taking hydrometer readings.

Using a hydrometer, measure the specific gravity
to determine the charge level and condition of the
batteries. If one or more of the battery cells test
lower than the other battery cells, the cell is
damaged, shorted, or is near failure. Replace the
battery if it is damaged.

MAINTENANCE

Clean the battery terminals after every 750 hours
of operation. Apply a light coat of dielectric grease
onto the terminals after they have been cleaned.

FOR SAFETY: When servicing machine, avoid
contact with battery acid.

If the machine is equipped with a maintenance
free battery, clean and tighten the battery
connections after the first 250 hours of operation
and after every 750 hours after that. Do not
remove the vent plugs from the battery or add
water to the battery.
