OPERATION
SWEEPING AND BRUSH INFORMATION
Pick up oversized debris before sweeping. Flatten
or remove bulky cartons from aisles before
sweeping. Pick up pieces of wire, twine, string,
etc., which could become entangled in brush or
brush plugs.
Plan the sweeping in advance. Try to arrange long
runs with minimum stopping and starting. Sweep
debris from very narrow aisles into main aisles
ahead of time. Do an entire floor or section at one
time. Sweep as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
sweeper. Overlap the brush paths.
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.
Use main brush II Speed when picking up light
litter. This will improve both litter pickup and
hopper loading. Do not use the II Speed speed in
dusty environments. The machine can dust and
clog the hopper dust filter. Operate the main brush
in the Normal position when picking up general
debris.
07817
For best results, use the correct brush type for
your sweeping application. The following are
recommendations for main and side brush
applications.
Polypropylene 8-double Row Main Brush -Gives superior pickup of sand, gravel, and paper
litter. Retains its stiffness when wet, and can be
used indoor or out. Not recommended for
high-temperature debris.
Polypropylene and Wire 8-double Row Main
Brush -- The wire bristles loosen slightly packed
soilage and heavier debris. The polypropylene
bristles sweep up the debris with excellent hopper
loading.
08587
40
800 Gas/LPG 330120 (9--97)
OPERATION
Crinkle Wire 8-double Row Main Brush -- The
stiff wire bristles cut through compacted grime,
hard to sweep dirt, and dirt mixed with oil, grease,
or mud. This brush is recommended for foundry
sweeping where heat may melt synthetic bristles.
This brush has good hopper loading ability, but is
not recommended for dusty applications.
Nylon 24-row Main Brush -- Recommended for
severe dust conditions on rough surfaces. This
brush has excellent pickup and long life.
Nylon Patrol Main Brush -- Designed for
sweeping large indoor or outdoor areas at higher
speed. The patrol pattern gives excellent loading
of light bulky debris (leaves and paper), while the
nylon bristle gives long life.
Heavy Gauge Polypropylene 8-double Row
Main Brush -- Designed for sweeping outdoor
areas. The stiffer bristles allow excellent loading
of heavier bulky debris (leaves and paper litter).
Polypropylene Side Brush -- A good general
purpose brush for sweeping of light to medium
debris in both indoor and outdoor applications.
This brush is recommended when bristles may
get wet.
Nylon Side Brush -- A longer life, general
purpose brush that is recommended for rough
surfaces.
Flat Wire Side Brush -- Recommended for
outside and curb-side sweeping where soilage is
heavy or compacted. The stiff wire bristles dig out
soilage. This brush is also recommended for
foundry sweeping where heat may melt synthetic
bristles.

REGENERATIVE FILTER SYSTEM (RFS)
The Regenerative Filter System (RFS) is an
option that alternately turns on the filter shaker
motors when the filters need cleaning because of
a build--up of dust or debris.
Normally the RFS does not require the operator to
stop the machine to shake the filters during
sweeping operation (except in extreme and
severe dust environments). However, it is
recommended that the filters are shaken at the
operator’s initiative each time the hopper is
dumped. This can be accomplished during transit
to a dump sight. AVOID shaking the filters while
hopper is in a rolled out position. To initiate a
shaking cycle, press the filter button on the
instrument panel. See FILTER SHAKER
SWITCH.
In very severe dust environments, the plugged
filter indicator on the instrument panel may remain
lit. When this occurs, it is recommended that the
operator stop the machine and initiate one or two
shake cycles to clear a possible plugged filter
condition. After shaking, roll the hopper out to
evacuate the dust tray. Resume sweeping
operation.
If the hopper is over full, the light may come on.
Check the hopper load and dump if necessary.
If the filter light remains on after all the above
conditions are corrected, the filters may be
plugged or the RFS may be inoperative. Filters
may be shaken by the operator initiative by
pressing the filter button on the instrument panel if
there is a failure in the RFS control system.
Successful operation of the RFS option requires
clean, undamaged filters. Plugged filters may
cause the RFS to cycle continuously even at start
up. The option also requires good sealing of the
upper lid to the hopper, as well as a good seal
between the two upper filter chambers.
It is recommended that the machine be driven for
some test sweeping with the RFS option at initial
start up. This next step assumes the hopper cover
and upper filter chamber of the hopper was
cleaned thoroughly prior to installation of the RFS
option. Sweep for 30 minutes and open the
hopper cover to check the integrity of the seals.
Look at the top of the shaker panels and the
underside of the hopper cover. Check for any
signs of dust tracking that may be caused by a
bad seal or filter. Repair a necessary. Perform this
check periodically while using the sweeper with
the RFS option.

HYDRAULICS
HYDRAULIC FLUID RESERVOIR
The reservoir is located behind the operator seat.
Mounted on top of the reservoir is a filler cap with
a built-in breather. Replace the cap every
800 hours of operation.
08452
Check the hydraulic fluid level at operating
temperature every 100 hours of operation. Make
sure the hopper is down when checking hydraulic
fluid level. The sight gauge is marked with FULL
(black line) and ADD (red line) levels to indicate
the level of hydraulic fluid in the reservoir.
Lubricate the filler cap gasket with a film of
hydraulic fluid before putting the cap back on the
reservoir.
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.
08430
Drain and refill the hydraulic fluid reservoir with

The higher temperature fluid has a higher
viscosity and should not be used at the lower
temperatures. Damage to the hydraulic pumps
may occur because of improper lubrication.
The lower temperature fluid is a thinner fluid for
colder temperatures.
If another hydraulic fluid is used, make sure the
specifications match TENNANT’s hydraulic fluid
specifications. Using substitute fluids can cause
premature failure of hydraulic components.
66
800 Gas/LPG 330120 (10--2013)
MAINTENANCE
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 HOSES
Check the hydraulic hoses every 800 hours of
operation for wear or damage.
Fluid escaping at high pressure from a very small
hole can be almost invisible, and can cause
serious injuries.
See a doctor at once if injury results from
escaping hydraulic fluid. Serious infection or
reaction can develop if proper medical treatment
is not given immediately.
FOR SAFETY: When servicing machine,
use cardboard to locate leaking
hydraulic fluid under pressure.
If you discover a fluid leak, contact your
mechanic/supervisor.
00002
PROPELLING MOTOR

enough torque to align the slotted nut and the
shaft hole after the first 50-hours of operation, and
every 800 hours there after.
ENGINE
COOLING SYSTEM
Check the coolant level in the reservoir daily. The
coolant level must be between the two indicator
marks when the engine is cold.
Use clean water mixed with a permanent-type,
ethylene glycol antifreeze to a --34_ C (--30_ F)
rating. The coolant level should be 25 to 50 mm (1
to 2 in) below the filler opening.
FOR SAFETY: When servicing machine,
avoid contact with hot engine coolant.
800 Gas/LPG 330120 (10--2013)
67
MAINTENANCE
Check the radiator hoses and clamps every
200 hours of operation. Tighten the clamps if they
are loose. Replace clamps if they no longer
tighten properly. Replace hoses if they become
hard, cracked, or swollen.
Check the radiator core exterior and hydraulic
cooler fins for debris every 100 hours of
operation. Blow or rinse all dust, which may have
collected on the radiator, in through the grille and
radiator fins, opposite the direction of normal air
flow. The grille and hydraulic cooler open for
easier cleaning. Be careful not to bend the cooling
fins when cleaning. Clean thoroughly to prevent
the fins becoming encrusted with dust. Clean the
radiator and cooler only after the radiator has
cooled to avoid cracking.
08432
FOR SAFETY: When servicing machine,
wear eye and ear protection when using
pressurized air or water.
Flush the radiator and the cooling system every
400 hours of operation, using a dependable
cleaning compound.
AIR FILTER INDICATOR
08454
The air filter indicator shows when to replace the
air filter element. Check the indicator daily. The
indicator’s red line will move as the air filter
element fills with dirt. Do not replace the air filter
element until the red line reaches
5 kPa (20 in H2O) and the ”SERVICE WHEN
RED” window is filled with red. The indicator’s red
line may return to a lower reading on the scale
when the engine shuts off. The red line will return
to a correct reading after the engine runs for a
while.
Reset the air filter indicator by pushing the reset
button on the end of the indicator after replacing
the air filter element.
AIR FILTER
The engine air filter housing has a dust cap and a
dry cartridge-type air filter element. Empty the
dust cap daily. The air filter must be replaced
whenever the filter element is damaged or when
the optional air filter indicator shows a restriction.
The air filters cannot be cleaned.
All machines have a heavy duty safety element
inside the standard element. Replace this
element, do not clean it, after the regular element
has been damaged or changed three times.

800 Gas/LPG 330120 (7--10)
69
MAINTENANCE
The fuel injection system is equipped with a
“manifold absolute pressure sensor” (MAP
Sensor). The MAP sensor senses barometric
pressure and automatically corrects the fuel
system calibration for changes in altitude. This
means the air/fuel mixture will always be
optimized, regardless of elevation (or barometric
pressure), however, the engine will still lose 3.5%
power for every 1000 ft increase in elevation.

If the machine becomes disabled, it can be
pushed from the front or rear, but towed only from
the rear.
The propelling pump has a bypass valve to
prevent damage to the hydraulic system when the
machine is being pushed or towed. This valve
allows a disabled machine to be moved for a very
short distance and at a speed to not exceed 1.6
kp/h (1 mph). The machine is NOT intended to be
pushed or towed a long distance or at a high
speed.
ATTENTION! Do not push or tow
machine for a long distance and without
using the bypass valve, or the machine
hydraulic system may be damaged.
