Safety instructions
!Read the following safety instructions before
putting the leaf vacuum trailer into operation
Read this manual trough with care before using the leaf vacuum trailer.
Stricly follow all directions and always pay attention to t
Ensure that everyone using the leaf vacuum trailer knows and actually applies the instructions.
The leaf vacuum trailer is allowed to be used only by appropriately qualified persons.
Read the manual of the tractor
Read the manual of the PTO drive shaft (comes with the PTO drive shaft on delivery).
Only use universal joint shafts with CE marking. Never work with damaged protecting tubes
or while they are removed.
Wear ear protectors at noise levels exceeding 80 dB(A).
Be mindful of very hot parts after the hydraulic system has been (over)loaded.
Switch off the PTO shaft when not working with the leaf vacuum
trailer.
Do not work at dusk or in the dark, unless you have arranged for proper lighting.
Check te ensure that the speed as set and the direction of rotation
of the PTO shaft correspond tot the recommended rpm.
If there are no pertinent legal regulations, ask suppliers of oil, filters, batteries/accumulators,
fuel, antifreeze, cleaners etc. for information about the effects of these substances on human
beings and Nature as well as about the safety rules to be followed for their use, storage and
disposal or destruction.
Make sure that there is no one behind the leaf vacuum trailer before backing it. If you do not
have a complete view of the area behind the leaf vacuum trailer, you may back it only if
someone else positioned at sufficient distance from the rear of the leaf vacuum trailer is
directing you.

Take into account the height, width and length of the leaf vacuum trailer when moving it.
When using public roads, you are yourself responsible for complying with the local regulations
(marking. required documents, exemptions, lighting etc.)
Install replacement lighting if the tractor lighting is concealed by an implement.
Adjust your driving style to the circumstances. The driving characteristics of the tractor are
influenced by the leaf vacuum trailer and the condition of the road.
Work and drive with utmost caution if there are people in close vicinity. Attention! Make sure there
are no persons behind the leaf vacuum trailer when tipping.
Before remedying malfunctions, carrying out maintenance or settings/adjustments of the leaf
vacuum trailer: always place the red safety support under the container and wedges behind the
wheels. Turn off the implement, wait for the implement to come to a standstill, switch off the PTO
shaft, turn off the engine and remove the key from the ignition lock.
Bear in mind that the hydraulic system operates with oil under high pressure. An oil jet under
high pressure may be invisible, penetrate the skin and cause serious injuries. Therefore, never
try to locate or stop a leak by hand. In the event of injury caused by oil leakage, consult a
physician immediately because of the risk of infection.
Watch out for oil squirting out when a coupling is or has
been loosened. Oil can squirt out when a cylinder is
moved by a force from outside.
Only use hoisting elements which meet the current standards (NEN-EN 1492 hoisting belts).
Stickers and markings contained in this manual and provided on the leaf vacuum trailer give
important directions for nonhazardous use. Follow these directions for your own safety! Never
remove them.
!Replace stickers that have been damaged immediately.
As a user, wear close-fitting clothing/safety goggles and ear protectors! Avoid wearing loose
clothing/garments!
After switching of the leaf vacuum trailer. The fan working shaft will still continue rotating. Stay
away from the rotating parts until the leaf vacuum trailer has come to a complete standstill.
Caution! When switching on the PTO shaft, both the fan and the working shaft will start instantly.
Couple accessories as prescribed and fix them only to the intended device. And ensure
they are properly secured.
Safety instructions
Never loosen hose couplings before you are sure there is no pressure on them. A weight may
cause pressure in a line.

Safety instructions
Ensure proper maintenance according to the instructions for use contained in this book.
Repair any damage immediately, and definitely before working with the leaf vacuum trailer again.
Important! Any other use is not in accordance with the intended purpose. See chap. 1
Check the whole leaf vacuum trailer each time before using it. Use the leaf vacuum trailer only if
all functions are working properly and no parts have been damaged.
For work to be carried out under the container, the red safety support must always be placed.
See chapter 7.1 for the location.
The PTO drive shaft may be coupled and uncoupled only when the tractor engine has
stopped and the ignition key has been removed.
The tractor must be equipped with a PTO shaft 1.3/8" ASE DIN 9611/A for 540 rpm.
Use a locking clip for securing the tow-bar pin after coupling the leaf vacuum trailer.
The coupling points of the PTO driveshaft on the tractor side and on the side of the leaf
vacuum trailer must be in line. If it cannot be avoided that the maximum admissible working
angle as described in the manual of the universal joint shaft will be exceeded, it will be
necessary to choose an alternative universal joint shaft with large-angle elements.
When tipping the container, make sure that the container does not come into contact with
overhead electric cables or overhanging obstacles.
!When tipping the container, make sure that the leaf vacuum trailer is positioned on a
horizontal ground.
!Attention! Tipping the container is allowed only when the PTO shaft has been switched off.

Product description
4.1 Description
The Votex B.V. leaf vacuum trailer is a modularly constructed machine which can be used with a wide
vacuum funnel with brush shaft, scarifier shaft or flail shaft. It is also possible to work with a suction system.
The leaf vacuum trailer is to be coupled at the rear of a tractor.
Cuttings are sucked up by the vacuum funnel with brush shaft, scarifier shaft or flail shaft and blown into the
vacuum trailer. Also, mowing and cutting waste, leaves and small litter can be sucked up by the suction
system and blown into the container. The container of the vacuum trailer can be emptied by operating the
tractor hydraulic system. The suction system and the vacuum funnel with brush shaft, scarifier shaft or flail
shaft are driven by the 540-rpm PTO shaft of the tractor. The suction system consists of a fan casing
containing an impeller. A vacuum funnel and a suction hose are connected to the suction system. Using the
changeover valve, it is possible to choose working either with the wide vacuum funnel with working shaft or
with the suction hose.
The leaf vacuum trailer can be divided into various component groups:
The container has a capacity of 4,2 m³ . The Cuttings can
be collected in this container.
The wide vacuum funnel with working shaft is located
under the container. Leaves and cuttings thrown up by
the working shaft are sucked up by the fan and blown
into the container.
