TENNANT A60
1. GENERAL
This operating manual belongs to the A60 sweeper vehicle.
The purpose of the manual is a safe use and maintenance of the sweeper vehicle and the
manual must be available for the operators at all times.
1.1. Purpose of the sweeper
The A60 sweeper vehicle is used for cleaning paved surfaces.
1.2. Operators
In this manual "the operator" refers to anyone who comes into contact with the A60 sweeper
or any of its components under operational circumstances. The organization itself should
ensure that every operator is sufficiently qualified to work with this type of vehicle and is
capable of taking the stipulations and safety aspects into account. A clear distinction is made
between two groups of operators:
-
”The driver" is the person who actually operates the vehicle in preparation of or
during the production process (sweeping process). The driver must be older than 18
years of age and be aware of his responsibilities.
-
”The technician” is the person who repairs or carries out maintenance on the vehicle.
The technician must be qualified and trained in technical actions. It is mandatory that
the technician has thorough technical understanding and is able to read technical
drawings.
The driver and the technician must be instructed properly before operating or carrying out
maintenance on the vehicle. The initial instructions are given by specialists from Tennant
N.V. an exception is made if the organization in question already operates several vehicles of
the same type, or has sufficient in-house expertise.
Tennant N.V. cannot be held responsible for work carried out by inadequately instructed or
unqualified operators.
1.3. Emission data
The hydraulic system of the A60 sweeper vehicle contains hydraulic oil and is powered by a
diesel engine, which complies with the euro-4 legislation. The battery of the A60 sweeper
vehicle contains battery acid.

Identification plate
The identification plate of the A60 is attached on the (lower) side of the passenger seat.
1.5. Functionality description
The A60 is a sweeper vehicle, exclusively designed for the cleaning of paved surfaces. The
refuse in front of the vehicle is collected beneath the vehicle by two brushes. There it is
sucked through the suction mouth and transported to the dirt hopper. The suction force in the
suction mouth is created by under-pressure in the dirt hopper. The fan on the dirt hopper
pumps the air out of the dirt hopper and releases it to the outside air through the air extraction
duct in the top of the dirt hopper. A labyrinth inside changes the direction of the air stream
several times, thereby reducing the noise. The refuse is moistened in the suction mouth so that
it precipitates onto the floor of the dirt hopper and cannot be blown out again.
The power supply for all the motorized components of the sweeper vehicle is supplied by a
hydraulic system. This hydraulic system is in turn powered by the diesel engine. This type of
power supply ensures that the diesel engine can maintain a constant engine speed and that all
other actions (steering, linear or rotating) are generated by regulating the hydraulic fluid flow.
For instance, the driving action, the steering mechanism, the hydraulic cylinders, the
sweeping unit and the suction fan are all driven hydraulically.
Only the driving speed and fan speed are directly affected by the power and speed of the
diesel engine.

Only drain cold hydraulic fluid.
Under no circumstances may the engine be started or operated manually once the hydraulic
fluid has been drained.
Collect spilt and drained-off hydraulic fluid in a container and dispose of in an
environmental-friendly manner.
Always check the hydraulic system for leaks when work of any kind has been completed.
Changing hydraulic hoses
» Hydraulic hoses must be regularly inspected.
» Hydraulic hoses should be replaced immediately in the event:
- that the outer mantle is damaged (e.g. graze marks, cuts, tears),
- that the outer mantle is brittle (tears in the hose material),
- that under pressurized or non-pressurized conditions, deformation occurs which is not
due to the original shape of the hose,
- that deformation occurs where the hose is bent (e.g. pressure points, bending points,
the outer mantle is detaching, bubble formation),
- of leaks,
- that a component is installed according to the guidelines,
- that the hydraulic hoses get separated from the couplings,
- corrosion of the couplings which reduces function and rigidity,
- of damaged or deformed couplings reducing function and rigidity.
Only original replacement hydraulic hoses from Tennant N.V. guarantee that
the proper hose type is used at the applicable place.

2.8. Emergency situations
An emergency situation occurs when people and/or the vehicle are in acute danger or if an
acutely dangerous situation is imminent. If an emergency situation develops, the operator
should immediately press the emergency stop. The vehicle will come to a complete standstill
immediately and all functions will be switched off.
The A60 sweeper vehicle is equipped with three emergency stops:
-
one in the cabin on the dashboard
one on the remote control
one in the engine compartment
The emergency stop on the dashboard is fitted with a key so that they can be locked during
maintenance or repair work.
The remote control can be carried anywhere in or around the vehicle. This ensures that the
operator or technician always has an emergency stop at hand in every situation and
workplace.
Only when the emergency situation is resolved the emergency stop may be
deactivated by turning the switch in the direction indicated by the arrow.
The driver can use the foot brake as an emergency brake while driving.

4. VEHICLE OPERATION
Always observe the safety regulations and measures described in section 2.2,
2.3, 2.4 and 2.7.
Before entering traffic, the operator should be sufficiently familiarized with the handling of
the sweeper vehicle. This applies particularly to the large steering radius (60°) and the
hydraulic drive mechanism.
After sufficient practice with the sweeper vehicle the operator may participate in traffic as
long as local traffic regulations are observed.
Drive carefully at all times, particularly when driving up or down gradients. This means that
the driving style should always be adapted to prevailing conditions.
•
•
All manoeuvres should cease if traffic conditions do not allow for their
execution.
In connection with safety:
o the vehicle must have sufficient lights, and
o the warning beacon must be switched on.
4.1. Before driving
Before driving the vehicle the “checkpoints for sweeping” in section 9.1 should
be studied.
» The seat must be adjusted to the driver’s preferences to improve seating comfort and
prevent physical complaints. For the adjustment options please refer to the original
operating manual of the chair (supplied).
» The mirrors should be adjusted manually so that the driver can observe the following
from his seat:

5. THE SWEEPING PROCEDURE
Always observe the safety regulations and measures described in section 2.2, 2.4
and 2.7.
Sweeper vehicles are mainly used to clean public roads. The type of refuse usually consists of
litter, sand, grit and leaves. The dust that develops during sweeping is settled by continuously
spraying it with water.
The quality of the sweeping results is largely determined by the adjustments and settings. The
adjustment of the brushes depends on various factors (see also section 9.2.2 and 9.2.3). When
selecting the driving speed and the brush speed, prevailing conditions should be taken into
account.
The joystick control of the sweeping unit and the wide steering angle make the vehicle highly
manoeuvrable during the sweeping procedure. Always adapt the manoeuvring to the
prevailing conditions.
In due course, the operator will become sufficiently experienced to assess the conditions
accurately and adapt the sweeping techniques accordingly.
5.1. Sweeping conditions
The settings of vehicle's functions must be based on prevailing conditions. These settings can
be adjusted while sweeping, as long as the vehicle and the sweeping procedure remain under
control and the operator's attention is not distracted from the traffic.
Adjustment of the sweeping unit and/or third brush must always be done very
carefully.
No obstacles or people may be within the danger zone.
Road speed
While sweeping, the road speed must be adapted to the prevailing conditions. A maximum
speed of 7 km/h is recommended. During sweeping the tortoise-speed is automatically
selected. This means that the maximum vehicle speed is set at ± 12 km/h forward and ± 8
km/h in reverse at an engine speed of ± 1300 revs/min.
The engine speed during sweeping is set by means of the speed regulator in the central cab
switchboard (fig. 6, no. 1). The accelerator pedal therefore only influences the driving speed.
A sudden switch to reverse at normal sweeping speed could cause hazard to
traffic approaching from the rear.

Suction power
The vehicle's suction power is determined by the diesel engine's speed. Under standard
conditions and at engine speeds between 1300-1500 revs/min, wear, fuel consumption and
noise levels will be reasonably attuned to the vehicle's performance.
Suction mouth
Larger pieces of rubbish or large amounts of leaves can be sucked in through the front of the
suction mouth which can be opened by means of the joystick (fig. 21, no. 4).
Keep in mind that the suction power is reduced when the mouth is open.
If the suction mouth is blocked (by twigs, for example), it can be unblocked by switching off
the fan (fig. 6, no. 10), drawing the suction mouth upwards (fig. 6, no. 14) and reversing a
small distance to check that the blockage has been removed.
Brush speed
The brush speed must be adapted to prevailing sweeping conditions, such as the litter
situation, the surface or the road speed.
When the brush speed has to be adjusted, the vehicle must first be brought to a
halt. This must be done in order to keep track of the traffic situation.
The brush speed can be regulated by means of a knob on the central switch panel (fig. 6, no.
3). The knob can be turned down to 0. Select an appropriate brush speed, but not too high.
High brush speeds lead to increased brush wear and can cause objects, like
small stones, to be flung away.
Water pressure
The water circuit is set to a fixed pressure. Under normal conditions this pressure is sufficient
to keep the suction mouth clean and prevent accumulation of dust.
Sprayers
The sprayers must be activated in dry conditions to prevent dust from developing
(fig. 6, no. 6).
Excessive use of water should be avoided during sweeping!
The amount of water in the vehicle is limited.
Inspection hatch
The inspection hatch is located on the right-hand side of the dirt hopper. The hatch can be
opened to put pieces of rubbish that are too big for the suction mouth (for instance branches)
into the dirt hopper. It is recommended to switch the suction fan off before opening the hatch
(fig. 6, no. 9).

Outside temperature
Because the water is heated permanently by the hydraulic fluid coolers which are located in
the water tanks it is possible to sweep in temperatures below 0 degrees Celsius.
However, only use this option if circumstances actually warrant it.
There is always the risk of ice formation and freezing. After all, freezing
increases the risk of possible breakdowns and damage.
Sweeping techniques
Sweeping techniques can help the driver to:
•
obtain good sweeping results, and
•
carry out the work at an effective speed.
Low driving speeds ensure that the manoeuvrability of the vehicle is used optimally.
Excessive steering manoeuvres result in increased tyre wear.

When the brushes are set at a forward angle, the rear of the brush does not touch the surface.
This brings the rubbish in front of the suction mouth so that it does not revolve with the brush.
The sideways angle is adjusted to the shape of the surface or the degree of brush wear. Some
vehicle models are equipped with a hydraulic sideways adjustment that can be operated from
the cabin.
If the sideways angle is too large, it will create space between the brush and the
suction mouth, leaving a line of rubbish behind. This effect increases with
increased brush wear.
Figure 31:
1) Unscrew the 2 nuts "A" of the brush suspension.
2) Set the forward angle:
- Turn bolts ‘B’ to the right to increase the
forward angle.
- Turn bolts ‘B’ to the left to decrease the
forward angle.
3) Set the sideways angle:
- Tilt the brush by hand to adjust the sideways
angle to the surface.
4) Once the correct setting has been obtained, tighten
the 2 nuts ‘A’.

Adjusting the brush pressure
Figure 31: Adjusting the brush angle
The correct setting for the brush pressure among other
things depends on the type of litter, the surface, the brush wear and the driving speed. Taking
into account these circumstances an acceptable brush pressure must be selected.
The brush pressure is regulated hydraulically. For this purpose operate the following two
switches on the central cab switchboard (fig. 6):
•
Switch 11
: pressure adjustment left-hand brush
•
Switch 12
: pressure adjustment right-hand brush
Excessive brush pressure results in increased brush wear

9.3. Maintenance after sweeping
A number of fixed maintenance tasks must be carried out daily after sweeping is completed.
For this maintenance work the high-pressure lance (optional) or a high-pressure cleaner can
be used. Chapter 6 contains a detailed description of the use of the high-pressure lance
(optional).
•
The handbrake must be engaged during cleaning of the vehicle.
•
The doors and windows of the cabin must be closed during cleaning of the
vehicle with the high-pressure lance or high-pressure cleaner.
•
The engine compartment may only be cleaned when the engine is switched
off. Therefore, the high-pressure lance cannot be used for this purpose.
1) Suction mouth and suction hose
•
Clean the suction mouth and suction hose.
•
Also clean the inside of the suction hose:
o Carry out the "Starting the vehicle" procedure (section 4.2) (engine speed ±1400
revs/min.).
o Temporarily switch on the suction fan and the water pump.
o Clean the inside of the suction hose:
Maintain a sufficiently safe distance from the vehicle while the diesel
engine is switched on.
2) Sweeping unit
Remove dirt from the sweeping unit with excess water.
3) Blow-off chamber and dirt hopper
•
Open the top door; respectively fully tip the dirt hopper.
•
Once the hopper is fully tipped, insert the safety pins.
•
Clean the blow-off chamber and dirt hopper with water.
•
Fully lower the dirt hopper.
•
Clean the ventilation grid via the inspection hatches.
4) Engine compartment and chassis
Before cleaning the engine compartment:
•
Fully tip the dirt hopper and insert the safety pins.
•
Switch off the engine completely.
Clean the entire engine compartment and chassis with water. Care should be taken when
cleaning with high pressure.
5) Exterior of the vehicle
Once the cabin is closed properly, clean the vehicle on the outside with water.
6) Cabin
•
The interior of the cabin may only be cleaned with a brush and a moist cloth. So no
excessive use of water!
•
The see-through hatch on the passenger side and the windows must be cleaned
thoroughly.

11. INTEGRATED AIR CONDITIONING/HEATING SYSTEM
11.1. Setting the temperature of the heater (5P1) and the airco system (5P2)
Temperature setting heater
(heater switched: lamp out 1 on)
•
Press “Set” once.
•
Go to 5P1 with the arrow keys.
•
When 5P1 appears in the display, press “Set”.
•
Adjust the temperature by pressing the up or down arrow keys.
•
After the adjustment, press “Set”.
•
Wait 15 seconds: the actual cabin temperature appears in the display.
This completes the temperature setting for the heater.
Temperature setting airco system
(airco system switched: lamp out 2 on)
•
Press “Set” once.
•
Go to 5P2 with the arrow keys.
•
When 5P2 appears in the display, press “Set”.
•
Adjust the temperature by pressing the up or down arrow keys.
•
After the adjustment, press “Set”.
•
Wait 15 seconds: the actual cabin temperature appears in the display.
This completes the temperature setting for the airco.
Attention!
» The heater and airco system only function when the blower has been switched on (fig. 7,
no. 27).
» To prevent the heater from switching on during hot spells, the heater temperature must be
set lower than the temperature for the airco system.
» If the cabin has been heated too strongly, the best thing to do is to open the window for a
little while to allow the hottest air to escape. However, the best cooling is achieved when the
windows are subsequently closed entirely.
» The optimum difference between the inside and outside temperature lies between 4 and 6
degrees. A larger temperature difference may cause colds.
» The adjustable outflow mouths can best be aimed at the source of heat or the window and
not directly at the people inside the cabin.
» The heating and air conditioning can be used simultaneously for a large part of the year.
The air is then first dehumidified by the airco system and subsequently brought up to an
agreeable temperature by the heater. This results in a very quick demisting of the windows,
even when the people inside are wearing damp clothes. The setting should then be as follows:
set the airco system 2° lower and the heater 2° higher than the inside temperature.
