6Descripon
6.1 General descripon of WEEDO
The WEEDO consists of a non self propelled power unit with a petrol engine
which powers a hydraulic driven brush for weed and debris removal from
hard surfaces.
The WEEDO is composed of a steel structure supporng control handles,
wheels, a petrol engine and the rotary tool holder (1 : F) to which wire
brushes (1 : H) are aached. The rotaon of the brush propels the unit
forwards and scrapes weeds from the surface towards a laterally mounted
splash guard (1: D)
7Assembly
8Operaon
8.1 Starng the Engine
Open Fuel valve ( Set to on)
To start engine from cold, slide the throle lever (1 : B) fully forwards away
from the stop posion. this is known as the choke posion where the engine
receives an enriched fuel mixture. Pull the starter cord. When the engine
starts return the throle lever slightly towards the stop posion unl it
locates in the rst detented posion. In this posion the engine rotates at its
maximum operang RPM and also the posion where the engine may be
started when warm. During the starng process the lever for the PTO (1 : C)
must not be actuated. Further informaon regarding starng the engine may
be found in the engine manufacturers instrucon manual.
8.2 Driving O
The single axle machine does not have a facility to be self propelled and must
be moved by hand.
It is possible to raise the brushes clear of the ground by pushing down on the
handlebar (1 : A). This will help manoeuvring the machine to the correct
locaon. and enable the brush to be engaged prior to contact with the
surface.
The brush rotor is power driven and engaged by the operaon of pressing
down the actuaon lever ( 1: C). This should be done carefully with the brush
in the slightly raised posion so that it is just clear of the ground to avoid any
unwanted reacons as the brush starts to rotate.
Gently lower the brush in to work and rest on the surface. There will be
some jerky movements as the brushes bite in to the debris on the surface.
Hold the handle bar rmly at all mes. The rotaon of the brush we pull the
wheels to provide forwards travel. The operator must remain alert during this
operaon to guide the machine in the desired direcon and speed.

15
8.3 Seng the Brush Rotor
8.3.1 General
The angle of the WeedBrush head is adjustable on 2 axis.
Figure ( 2 : K ) shows the favoured working area of the brush to provide the
best performance in most cases. Generally speaking it is with the brush to
the right and slightly to the rear.
It has been noced that parcularly good results may be obtained aer
rainfall and damp weather.
The forwards speed is generally determined by the strength of the vegetaon.
8.3.2 Adjusng the Angle of the Brush
The fore/a incline adjustment of the brush plate is via the adjustment screw
(3: G). Before the adjustment may be made the clamping lever (3: J) must
be loosened. Once the desired seng is achieved the clamping lever must be
re-ghtened to lock the posion.
The le an right rotaon of the brush is made by adjusng the screws located
on the right hand side of the brush head unit ( 1 : K ). By loosening the top
and ghtening the boom more pressure is applied to the preferred working
area of the brush. By loosening the boom and ghtening to top less
pressure is applied to the preferred working area of the brush. This
adjustment will also have an impact on the forward progression of the unit.
8.4 Adjusng the Debris Guard
Following any adjustments to the brush angles and in the normal event of
brush wear the height of the debris guard must be checked as it is directly
linked. The guard reduces the possibility of material being thrown from the
machine working area during operaon. Its correct use and seng is
therefore very important.
Under no circumstances should the machine be operated without the
guard in its correct posion.
By loosening clamping lever (4: M), the splash guard (4: D) is adjustable in
height. The rubber ap (4: E) from the splash guard must be in working
posion lightly resng on the oor.

16
9Maintenance
9.1 General
The general safety rules found in secon 3.3.5 must be followed
Engine oil changes must take place at the recommended intervals according
to the manufacturers recommendaons.
Waste oils, fuels and lters must be disposed of separately and properly.
The WeedBrush must be regularly maintained. Failure to comply may result in
damage to the machine , persons or property.
Check all safety devices and parts for correct operaon before every use.
When carrying out repairs, maintenance, cleaning as well as reccaon of a
malfuncon ensure the PTO drive is disengaged and the engine has be
isolated by removing the key or sparkplug cap.
Following any work carried out on the machine , replace all guards and safety
features enrely before tesng and using.
Check all hydraulic connecons following the rst 5 hours of operaon.
Tighten as required. Should a leak sll remain then the following course of
acon should be tried. Ensure the system is depressurised. Loosen the pipe
securing nut around 1 turn, twist the pipe clockwise and anclockwise
around 1/2 turn around 3 mes and then reghten the lock nut. If this
fails to x the leak the seek further help from the supplier. Always use
protecve gloves and goggles when working on the hydraulic system.
9.2 Daily Maintenance .
Before each use check the hydraulic oil level. To carry out this procedure;
Ensure the machine is on level ground and engine isolated. Remove oil ller
cap ( 1 : L ), check the level on the dipsck. The oil should be showing on the
lower level on the dip sck sha. To conrm reading wipe the dipsck clean
and retest.
Check engine air intake lter for cleanliness. Clean or replace if required. See
engine manufacturers operator manual for further details.
Check engine oil level. Adjust as required. See engine manufacturers operator
manual for further details.
When cleaning do not use water on the engine. A brush and/or high pressure
air is desirable.
Check hydraulic ngs and hoses.
Check brush secons are mounted securely. Damaged brushes should be
replaced and any debris eg wire aached to the brush head must be
removed.
Check all moving parts for correct operaon and carry out trial run.
Check wheels for correct air pressure.
