Green Machine Operator Manual Page 5
Chapter 2
Getting to know your Green Machine.
How the machine works
The Green Machine works by airflow. As long
as airflow is maintained the machine should
sweep correctl y.
Two front brushes sweep any debris towards
the center of the machine.
The debris is then picked up by the flow of air
through the vacuum hose (a).
A powerful impeller fan not only creates the
vacuum, but also mulches the debris as it
passes through.
The impeller fan is very strong and robust.
Broken glass or bottles which pass through
the fan come out looking like rock salt with
no sharp edges for you to cut yourself upon.
The air and mulched debris is next blown up
through the back trunking (b).
A water spray jet inside the back trunking
dampens the dust-laden debris down as it
passes through.
The debris and air are then blown downwards
through a nylon filter screen that filters out
the debris and collects the debris in a
regular plastic trash bag.
The air escapes through the filter screen and is
finally blown out through a special fabric
filter bag that screens out any remaining
dust.
As this air escapes, then the suction hose
vacuums up more new air and debris.
The Green Machine is easy to drive. Simple
hand controls allow you to vary the speed in
forward and reverse, and there are
automatic brakes.
A powerful and quiet diesel engine provides
power not only for the impeller fan, but also
for the hydraulic system that runs both the
brushes and drive.
Depending on your model, you can either ride-
behind or walk behind your Green Machine
as you work.
The machines are equipped with lights, a
beacon and a horn or voice warning
message so that you may work safely
among pedestrians or motor vehicles.
All in all, you will quickly learn that your
machine saves a lot of time and physical
labor when sweeping compared to pushing
a broom.
We’ll next look at identifying the major
features of your Green Machine.

Chapter 3
Preparing for your first use.
This chapter will guide you through the adjustments needed to optimize your Green
Machine for its first use.
Setting the suction nozzle
height.
It is important to check that the suction nozzle
height is correctly set.
If the suction nozzle is too high off the
ground, then suction performance will be
reduced.
If the suction nozzle is too low to the
ground, then the suction nozzle will
make contact with uneven surfaces and
the horseshoe-shaped skid underneath
the suction nozzle will get worn down
and will need to be replaced.
Always set height with machine on level ground.
Remove the castor locking pins (one on each
side).
It helps to move the wander hose to the side to
allow access to the left-side locking pin.
rotating the castor caps on each side.
Turn the caps clockwise to raise the nozzle, or
anti-clockwise to lower the nozzle.
You should adjust both sides to leave just
enough space for your fingers to fit between
the horseshoe-shaped skid and the ground about ¾ “ (20mm) at each side is good.
If the surface that you are sweeping is very
uneven, then you may wish to raise the
nozzle a little more.
You will have to check and readjust the
nozzle height from time to time. This is
because the castor wheels that hold the
suction nozzle off the ground will wear
down as you use your machine. Failure
to periodically check the nozzle height
can mean expensive repairs if your front
nozzle wears down.
Fitting the brushes.
Adjust the nozzle to the correct height by
Green Machine Operator Manual Page 8
Tilt the machine rearward to gain easier access
to the front of the machine.
Turn the plastic locking cam (a) so that the lugs
on the cam line up with the lugs on the
metal drive hub (b).
Unhook the brush.
Push down on the brush assembly until you feel
the brush can move down no further.
Fit the new brushes and turn the locking cam
until you feel a solid click. This click means
that the brushes are now in the fully locked
position.
The cam on the left side of the machine locks in
the opposite way to the cam on the right
side. This is so that both cams are selftightening when the brushes are turning.
Setting the brush height.
Always check the suction nozzle height is
correct before adjusting the brush height.
The correct brush height is when the tips of the
brush bend slightly as shown.
If when you push down, the brush spreads out
too far then the brushes are set too low.
This will not improve the quality of
sweeping, but your brushes will wear out
much faster.
As you use the machine and the brushes
wear down, you will have to re-adjust the
brush height from time to time.
Green Machine Operator Manual Page 9
Removing the protective
plastic sheet.
Your Green Machine is often shipped with a
protective plastic sheet fitted inside the back
trunking that must be removed prior to first
use.
First ensure you remove the ignition
keys so that the machine will not start
accidentally.
Never start the machine with the back
trunking open.
Fitting the plastic trash
sack.
Open the zipper (a) on the filter bag (b).
Undo the two toggle clamps (b) and swing out
the back trunking (a).
Remove the protective plastic (c).
Close the back trunking by first lifting the hinge
lock pin and then swinging the back trunking
closed.
Re-fasten the toggle clamps.
Un-fasten the toggle clamp (a) and pull out the
sliding frame (b) towards you.
Remove the plastic screen and holder (a) and
insert the screen inside a regular 30 gallon
Page 10 Green Machine Operator Manual
(70 Litre) plastic trash sack.
Now insert the plastic sack and screen back
into the sliding frame.
Please make sure that the plastic sack
edges are folded around the outer sliding
frame, and not around the inside screen
holder (a).
If you fit the plastic sack in the wrong way,
your machine will not pick up properly.
Close the sliding frame and refasten the toggle
clamp.
Zip up the filter bag and close the top cover.
Now you are ready to go to the next chapter
– daily operator checks.
Green Machine Operator Manual Page 11
Chapter 4
Daily checklist.
These checks must be done daily before starting
Check the engine oil level.
Ensure that the engine oil level is between the
minimum and maximum marks on the
dipstick (a). Top up as required.
Use regular motor oil – 10W40 grade is
recommended.
If you need to top-up the oil, you can do so
through the filler cap (b) that is located just
below the dipstick.
Add a small quantity of oil at a time and recheck
the level frequently. Take care not to overfill.
Check the water tank
level.
Fill up the water tank with cold water by opening
the red filler cap (a).
You can see the water level in the tank using
the clear plastic sight tube (b).
You may wish to add a disinfectant to the water
system. Please see Chapter 6 for more
details.
Page 12 Green Machine Operator Manual
Check the diesel fuel
level.
Top up the fuel tank with regular diesel fuel if
required.
A full tank should last you about ten hours
running time.
Be careful not to spill any fuel– if you do so then
wipe off with a dry rag.
Avoid spilling diesel fuel on the air intake screen
that is located beneath the air filter housing.
If fuel spills on it, then dirt will stick to the screen
and may result in the engine starting to
smoke after some time. (Please see
Chapter 15 - Faultfinding).
Check the radiator
coolant level.
Open the radiator header tank pressure cap.
Take care when opening the pressurized
cap when the engine is hot. This is a
pressurized system with very hot liquid
inside.
The level should be 2” (50 mm) below the top of
the tank when the engine is cold.
Top up with a mixture of 50% water / 50% anti-
freeze when necessary.
Do not overfill, or else excess coolant will
escape out of the tank when the engine
heats up!
Check all electrical Items.
With the ignition key switched on to the first
position, check that the lights (a) and (b),
Green Machine Operator Manual Page 13
the beacon (c) and beeper (or optional voice
message) are all working correctly.
The switches are located on the control console
as shown.
Switch (a) operates the lights.
Switch (b) is a two-position switch.
The first position operates the beacon only.
The second position operates both the beacon
and the beeper or voice warning.
Your Green Machine incorporates Safety Inter-
Lock switches on the Suction Fan Front
Access Panel and on the Rear Trunking.
If either of these items are opened or removed,
the engine will be stopped and the engine
starter will be Isolated.
However, Prior to opening or removing these
items, the engine should be switched off
and the ignition keys removed.
To check that these switches are functioning
correctly, switch off the engine and swing
open the Rear Trunking. STANDING WELL
CLEAR of the open trunking, turn the
ignition switch to the engine start position.
The engine SHOULD NOT CRANK. If it
does, report immediately to your supervisor.
If the engine does not crank with the rear trunk
open, then the safety switches are operating
correctly.
Close the rear trunking. NOTE:- In spite of the
fact that the machine is fitted with safety
Inter-Lock switches, the engine should
always be switched off and the ignition keys
removed before opening the Suction Fan
Front Access panel or the Rear Trunking.
Check the water sprays.
Check that the water spray jet in the back
trunking is working – see Chapter 6 for more
information.
Check that the water spray jets for the brushes
are working – see Chapter 6 for more
information.
Page 14 Green Machine Operator Manual
After all checks have been completed close the
top cover, ensuring that it is correctly
secured.
Replace the wander hose (b) correctly in its
holster (a).

Starting, stopping and driving
Starting the engine.
Never start the engine if the front suction
hose is removed or the back trunking is
open.
Never run the engine continuously in a
confined, or enclosed space.
Insert the starter key into the key-switch.
Turn the key to position I.
When the engine is cold : turn the key to
position II and hold for five seconds. The
orange light on the control console will
indicate that the glow plug engine preheater is warming the engine.
When the engine is warm you can omit this
step.
Now turn the key to position III and the engine
will start.
After the engine starts, immediately let go of the
key and it will return to position I.
Stopping the engine.
Turn the Key to position 0 and the engine will
stop.
The emergency engine
shut-off button.
If the engine fails to stop when the key is turned
to position 0, then it is likely that there has
been an electrical problem that is preventing
the engine from shutting down correctly.
Should either of the red warning lamps
on the operator console for OIL or
CHARGING remain illuminated when the
engine is running, then the engine must
be shut down and the fault reported to
maintenance.
Green Machine Operator Manual Page 17
To stop the engine in this case, pull the red
button (a) located under the handlebars on
the right side of the machine.
Report the fault to your maintenance staff.
Setting the brush speed.
The brush speed lever is the bottom lever (c) on
the right hand side of the operator console
and has a black handle.
For normal sweeping set the lever at mid
position.
The brush speed can be changed for different
conditions.
For example, when sweeping a high volume of
leaves or when scrubbing you can set the
brush speed higher.
When sweeping glass, dog fouling, vomit,
spilled food etc., then slow the brushes
down.
If the brush speed is set too high, trash will be
thrown too far across the path of the
machine and the brushes will also wear
faster.
If the brush speed is set too low, then trash will
not be thrown far enough to allow pick-up,
and also the brushes will tend to bounce up
and down as you drive forward.
Setting the engine speed.
The throttle lever (b) is also on the right hand
side of the operator console and has a red
handle.
When running your machine, always use the
minimum engine revs that you need to pick
up the material being swept.
Start off with just under half power.
For machines equipped with a tachometer (rev
counter) this would be 2200 r.p.m.
The throttle speeds will need to be set
according to the nature of the debris you are
sweeping.
Use a mid position for general sweeping such
as dry litter and leaves.
You may need a three-quarter position for large
volumes of litter.
You may have to use almost full throttle when
sweeping heavy material such as thick
deposits of grit and dirt.
Wet conditions will also need a higher throttle
setting.
Try not to use too much throttle, particularly
when your filter bag is clean at the start of
your shift.
Too much throttle means too much airflow. The
dust and debris that you pick up will blow
into the plastic trash sack and will blow
straight back out again. The dust will then
be blown hard against the surfaces of the
filter bag, which results in a loss of suction
performance.
So although it seems strange at first, the lower
Page 18 Green Machine Operator Manual
the throttle setting that you use, the longer
your machine will sweep efficiently.
The Front Flap
There is a flap opening at the front of the
machine.
Opening the flap allows the pick-up of bulkier
debris such as plastic bottles, paper cups,
leaves etc.
When sweeping heavier debris such as sand or
dust, the machine works best with the flap
closed.
Check that the parking brake (a) is released.
Using the right or left hand drive lever (a),
slowly squeeze the lever until the machine
moves forwards .
The more you squeeze, the faster the machine
will drive.
Stopping.
To stop the machine in forward or reverse just
let go of the drive levers.
The machine has what is called “hydrostatic
braking” or a “dead man’s handle” so that it
The topmost lever (a) on the control console
operates the flap.
will come to a controlled stop as soon as
you let go of the drive levers.
Driving in reverse.
Driving forwards.
Always have both hands holding the handles.
Check that it is all clear around you before
moving off.
Green Machine Operator Manual Page 19
Always ensure that there is sufficient room
behind you before reversing.
Pull back on the reverse drive lever (b) using
your left thumb until the machine starts to
reverse.
To stop the machine in forward or
reverse just let go of the drive lever.
The parking brake.
The machine is driven by hydraulics. When the
drive lever is operated the machine moves
in the direction chosen. On releasing the
drive lever the hydraulic system applies a
braking force to bring the machine to a
controlled stop. (This is called “Hydrostatic
Braking”).
However hydrostatic braking systems are not
sufficient to stop the machine gently
creeping down hills or inclines when the
machine is left on unleveled ground.
Therefore there is also a parking brake fitted to
the machine that should be used when the
machine is to be parked unattended.
To release the parking brake, press the button
on the end of the parking brake lever and
then move the lever to the fully up position.
Parking brakes are not fitted as standard
on model 414S2D walk-behind models.
Therefore do not leave this model parked
on any hill or incline.
The emergency brake
release.
Because the hydrostatic braking system is
engaged automatically when the machine is
not being driven in forward or reverse, then
the machine will be unable to be moved
when the engine is not running.
If a situation occurs where the engine cannot be
started and the machine needs to be
moved, the emergency brake release can
be opened. This is located on the right side
of the machine as shown.
Open the emergency brake release (a) by
turning it anti-clockwise just like a faucet.
When done, close the brake release valve
hand-tight only.
Do not use wrenches etc. since over-
tightening can damage the valve.
Do not open the emergency brake release
To engage the parking brake (a), push the
brake lever downwards until it locks.

if the machine is on a gradient unless the
road wheels are chocked or the parking
brake is applied.
