HSE Information
Safe use of all-terrain vehicles (ATVs) in agriculture and forestry –AIS Sheet 33
Introduction
This information sheet gives advice on the safe use of ATVs. It covers
the two main types used in off-road working in agriculture and
forestry, which are:
•sit-astride ATV / sit-in machines
•side-by-side mini-utility vehicles,
The Full HSE information sheet can be found here or using the QR
Code at the bottom of the article:
https://www.hse.gov.uk/pubns/ais33.pdf and must be read prior to
any ATV/UTV use. Below are related extracts to trailed machinery.
REMEMBER - GET PROPERLY TRAINED AND ALWAYS WEAR
HEAD PROTECTION
Training
Under the Provision and Use of Work Equipment Regulations 1998
(PUWER), there is a legal requirement for employers to provide
adequate training, and to ensure that only employees who have
received appropriate training in their safe use, including the use of
any towed equipment or attachments, are permitted to ride ATVs.
The same requirements apply to the self- employed. HSE regards
training provided by recognised training providers as being
adequate for the purposes of PUWER.
Protective clothing
More than half of all ATV riders have been thrown off at some time.
As these machines are not fitted with either a cab or roll bar, your
only protection is what you wear.
● Head protection is vital. The majority of ATV fatalities in the
UK in the last ten years have been caused by head injuries.
Nobody who died from head injuries was wearing a helmet.
Helmets would certainly have prevented most, if not all, the
deaths. You should always wear a helmet when riding an
ATV. All helmets should have a chinstrap and be capable of
being used with suitable eye protection. The type of helmet
chosen should be based on an assessment of the
circumstances in which the ATV will be used, eg the types of
surface travelled over and anticipated speeds. The harder the
surface and higher the speed the greater the degree of
protection needed. NB: Forestry helmets and industrial hard
hats are not acceptable for any ATVoperations.
● Wear clothing that is strong and covers your arms and legs.
Gloves are useful for protection and to keep hands warm in
cold weather for good control of the ATV.Wear sturdy, ankle-
covering footwear, eg boots or wellingtons that are strong,
supportive and have good wet grip.
● Protect your eyes from insects and branches with either a
visor or goggles.
Trailed equipment and loads
Ensure all riders know the manufacturers recommended
towing capacity and drawbar loading limit. Always operate
within these requirements.
Remember that your ability to control the ATV by your body
movements will be considerably reduced when carrying a load or
towing a trailer.
● When selecting trailed equipment look for:
- over-run brakes;
- a swivel hitch drawbar;
- bead lock rims on wheels;
- a low centre of gravity and a wide wheel track;
- a long drawbar; and
- attachment points for securing a load.
● Check the weight ratio between your ATV and its trailed load.
This needs to be assessed for each operation. As a general
guide, on level ground, braked trailed equipment can be a
maximum of four times the unladen weight of the ATV.For
unbraked trailed equipment the maximum should be twice
the unladen weight. These loads should be reduced when
working on slopes, uneven ground or poor surface
conditions. Follow the manufacturers advice for your
particular machine.
● Weight transfer is also important. Stability and resistance to
jack-knifing is improved if some load is transferred onto the
ATVʼs drawbar. Approximately 10% of the gross weight of the
loaded trailer is recommended, but this should not exceed
the manufacturers drawbar loading limit. Remember that
weight transfer can change dramatically when you start going
up or down hill.
● When selecting mounted equipment, make sure it is within
the manufacturers approved weight limit, with a low centre
of gravity, and controls which are easy to operate but do not
create a hazard. Where equipment is added to one end of the
machine, add ballast at the other end to maintain stability.
● Loads carried on racks must be well secured, e.g. with ratchet
straps, and be evenly balanced between the front and rear,
except where they are deliberately altered to aid stability
when going up or down a slope.
● Only tow a load from the hitch point. Loads towed from other
points such as the rear rack have caused sudden rear
overturning even on slight slopes or with slight acceleration.
Ropes or chains should not be used to drag a load where they
can become caught on a wheel. This may lead to
entanglement with the brake cable, causing unexpected
braking.

Description
The W240 Weed Wiper is designed for the selective application of herbicide to weeds / vegetation on
pasture.
The W240 Weed Wiper is a trailed attachment, with applicator roller rotated around a horizontal plane in
direction counter to the direction of motion. This ensures even coverage of the waterborne herbicide to
the underside of the weeds. The herbicide itself is applied to the applicator roller via sprayer nozzles
located above, fed from a tank and pump fitted to the top of the machine.
These machines should however only be used to perform tasks for which they were designed - use of the
machine for any other function may be both dangerous to persons, and potentially damaging to
components. Use of the machine beyond the stated usage may invalidate any applicable warranty, as well
as being potential in breach of applicable safety regulations.
Weed wiping using herbicide is a controlled practice, and as such should only be undertaken by
operators with the correct licences / tickets for the territory the machine is being used in!
Identification
Each machine is fitted with a serial plate (shown below) which details the following:
1. Model
2. Date of Manufacture (DOM)
3. Serial Number
4. Mass
When enquiring regarding spares or additional
equipment, ensure you have this information to hand.
Implement Decals
If your implement does not contain all of the decals shown below, please contact Chapman Machinery for
replacement decals before use. Note: All decals must be present and visible. It is imperative that these are replaced
if damaged to prevent potential harm to users.

Attachment
Before Attaching the Machine
Before attachment, ALWAYS ensure the following:
•All safety guards & decals are in good working order and correctly fitted
•Lubrication points have been lubricated as per scheduled maintenance period
•The tyres are free of damage and inflated to the correct pressure
•Electrical connections are free of dirt and moisture
Attaching the Machine
NOTE: This machine is designed to attach to the towing vehicle through a 50mm diameter ball hitch.
1. Reverse the towing vehicle up to the machine.
2. Attach the machine onto the towing vehicle’scoupling.
3. Attach the control cable to the control socket fitted on the towing machine, ensuring a secure connection.
4. If required, adjust application rate on controller. Wiper controller should remember the previous setting used,
unless it has been stored for extended periods without power.
WARNING: ENSURE CONTROL EQUIPMENT IS SECURELY ATTACHED TO THE TOWING VEHICLE BEFORE USE!
Initial Set-up
Sprayer Pressure
The Weed Wiper has been factory pre-set with clean water to operate at the correct pressure for nozzle
atomisation - different herbicides or wetting agents may affect the viscosity, and as such the pressure may
need to be adjusted. The pressure regulator and gauge are located on top of the sprayer tank - with the
rear guard removed, adjust the pressure such that the nozzles are atomising the spray - this will normally be
around 2.75-3.5 Bar (40-50 psi) on the gauge.
Height
Hitch the weed wiper up to the towing vehicle, adjust the height of the roller to the desired level by
rotating the height adjustment jack to raise or lower as required. The height should be set so that the
roller contacts as much of the weed as possible without contacting the underlying grass sward. The more
contact that can be made with the weeds, the greater the chemical take-up and the better the wiping
result!
Initial Test Operation
In order to familiarise the operator(s) with the machine, first fill the spray tank with clean water, and test
operation using water only. The objective is to apply enough liquid to fully wet the applicator whilst moving
through the weeds, without overloading to such a point as the applicator drips onto the sward below.
Once the operator(s) are familiar with the machine and operation, the tank can be drained and refilled with
water / herbicide as per the herbicide manufacturers recommendations.

Page 8
Operation
Ensure that the operator is suitably qualified to use a machine of this nature and handle chemicals (inc.
suitable sprayer qualification) and that they have fully read and understood this manual. It is advisable that
all ‘first time’ operators familiarise themselves with operation using clean water only at first.
AFTER APPROXIMATELY ONE HOUR OF WORK WITH A NEW MACHINE, ALL NUTS, BOLTS AND DRIVE BELTS
SHOULD BE CHECKED FOR TIGHTNESS AND ADJUSTED AS NECESSARY!
Chemical Application Rate
The chemical used should be approved for use in Weed Wipers (eg. Bayer Round-up Power-Max) and the
chemical should be diluted in accordance with the product label. If in doubt check with the chemical
supplier representative. As a guide, a typical dilution ratio for glyphosate would be between:
•20:1 –For cooler conditions or outside of the main growing season.
•40:1 - For warm conditions during the main growing season.
The stronger the mix used the less liquid you want on the wiper brush roller; as a guide if using at 20:1
when the roller is completely stopped you would expect some dripping to occur after approximately 20
seconds, and at 40:1 the dripping would occur after approximately 5 seconds. Ultimately the operator must
use their own discretion and chemical knowledge to balance dilution rate, application rate and forward
speed in order to get effective coverage without unnecessary chemical usage or overkill.
Control Module
ON/OFF: Switches the control box on or off. When switched on, the applicator roller will run continuously.
APPLICATION RATE: The desired spray rate is set using the up/down arrows, with the current output value
(between 0 & 100) displayed on the 3-digit display. For example, the machine will run for 50% of the time
when set to 50 on the control box. RECOMMENDED START VALUE = 15%
PUMP RUN: Switches the sequenced pump on or off so that chemical is applied to the applicator at the
application rate set.
PURGE: This runs the pump continuously when pressed, ideal for clearing blockages, purging the system of
air or when flushing through with water after use.

Page 9
Procedure
1. Switch the unit on by pressing ON/OFF. The display will light-up and the roller will rotate.
2. After approx. 3 seconds the display will show the previous application rate last used between 0-100.
Use the UP / DOWN arrows to adjust if required.
3. Press the PUMP RUN button to commence the application of herbicide.
4. The machine will continue to run at this rate until the control is turned off or the amount is altered.
5. When finished, switch off by pressing ON/OFF. The unit should always be cleaned with fresh water
and the tank purged when application is finished, to prevent crystallisation of the chemical in
pipework and nozzles.
Forward Speed
The forward speed used should be proportional to the amount of weeds being encountered. In areas of thin
weed growth, a faster speed (for example 5mph) will result in an effective kill and improved workrate.
Conversely, in areas of thick weed growth, forward speed will need to be reduced to a slow walking pace
(around 2mph) in order to effectively wipe all the weeds.
Operating Limits
WARNING: DO NOT OPERATE BEYOND OPERATING LIMITS, DAMAGE TO MACHINERY OR INJURY TO
OPERATOR MAY OCCUR.
Minimum / Maximum Temperature: 5°C / +40°C
Storage
The machine should be thoroughly hosed down with clean, low pressure water and lubricated after use
to prevent corrosion due to herbicide residue left on the machine. The machine should only be put into
storage once fully dry, and should be kept under cover when not in use.
Wiring Colours
In cases where the plug /socket or wiring has been damaged, the wiring may need to be checked, the following
colours are used:
Red = Pin 1 = Motor –
Green = Pin 2 = Motor +
Brown = Pin 3 = Pump +
White = Earth = Pump -
