and authorised person. Preferably, you make yourself familiar with its basic
functions and its operation by testing it for the first time on an open and plane
ground.
•For further information and in case any problems occur whatsoever they
may be, please contact your seller, importer or directly ask the manufacturer.
•Also inform all other users about these safety instructions!
Apart from these, the local industrial safety regulations and the general safety
provisions are applicable for the area of use of the machine.

2.3 Intended use
WARNING
Risk of injury / risk damage to environment due to improper use of the
machine!
There is a risk of injury, as well as a risk of damage to environment and material
damages (on the machine or system) due to improper use of the machine!
•The one-axle carrier vehicle as well as the attachments released by the
manufacturer are built for the use für den respective usual or common
application and works in the field of agriculture and forestry, e.g. green
area conservation and premises upkeep as well as for winter service.
•Any other use will be regarded as unintended use. The manufacturer shall
not be liable for damages resulting from this; the risk is borne solely by the
operator.
•The intended use also includes the observance of all operating,
maintenance and servicing instructions prescribed by the manufacturer.
•The one-axle carrier vehicle is only allowed to be used, maintained and
repaired by persons who are familiar with it and have been instructed about
the risks.

UBS Hydro II
Safety EN
2018-05-02 11 / 60
•The applicable accident prevention regulations and the otherwise generally
approved regulations for safety and occupational health must be complied
with.
• Unauthorized changes on the machine cause the manufacturer’s exclusion
of liability for the resulting damages.
2.4 Work areas and danger zones
Fig. 1: Danger zone (top view)
Basically, the scope of delivery includes the machine as displayed and listed. It
refers to the UBS Hydro series.
•RED Danger zone
•GREEN Work area
WARNING
Risk of injury / risk damage to environment when working / staying within
the danger zone!
There is a risk of injury, as well as a risk of damage to environment and material
damages (on the machine or system) due to improper use of the machine!
•In the danger zone of the machine, the user has to ensure the safety of
third party!
It is not allowed to stay within the danger zone of the machine! Expel all people
from the danger zone.
•If any people approach the danger zone, the machine must be switched
off.

UBS Hydro II
Safety EN
2018-05-02 12 / 60
•The operator has to ensure that no persons or objects are within the
possible discharge area of an attachment.
•Before switching on the attachment and starting up of the machine, check
the danger zone. Mainly pay attention to children and animals. Provide for
sufficient sight!
•In poorly visible areas, switch the attachment off and make sure that
nobody is within the danger zone.
•Before starting work, remove all foreign bodies from the area to be treated.
While working, pay attention to other foreign bodies and remove them early
enough.
•When working in bordered areas, the safety distance to the border must be
kept to prevent the machine from being damaged.
•When working in close vicinity to public roads and paths make sure that the
discharge area is with the work area because there is a risk of injury for
third parties. Therefore, approach the working paths with rotating brushes
in longitudinal direction. If a weed brush is used, approach the working
path in transverse direction.
•When working near or in close vicinity to public roads and places, put up
information and danger signs to draw third parties’ attention.

accompanying person secures the host vehicle using a bar or a rope. The
accompanying person has to be above the vehicle at a sufficient distance
from the working tools! The assistant should wear pole climbers.
•Drive across the slope, if possible.
•Under humid and rainy conditions, do not use the machine at the slope.
•On steep slopes, use grid wheels or spike wheels to avoid sliding off.
•In case steering is troubled, immediately stop the self-propelled working
machine and switch the engine off. Immediately eliminate the malfunction.
•Before each commissioning, check the machine for operational safety!
•If the working machine starts sliding down at the slope, immediately let off
the handles.

cleaning works, should be rectified only when it is ensured that the
machine is at a standstill and is safeguarded against a restart.
•Release the blockages only when it is ensured that removing them will not
result in any dangerous movements of machine parts.
•Ensure adequate freedom of movement before starting the work.
•Pay attention to order and cleanliness at the assembly place! Parts lying
around loose or one above the other are sources of accidents.
- If components have been removed, pay attention to correct assembly,

WARNING
Risk of injury / risk damage to environment due to poor / missing
maintenance!
There is a risk of injury, as well as a risk of damage to environment and material
damages (on the machine or the system) due to poor maintenance!
•Only perform maintenance and cleaning works when the engine stands
still.
•When working on the engine, generally pull the spark plugs off.
•The operating personnel are allowed to perform simple cleaning and
adjusting works. Maintenance and service works are only allowed to be
done by instructed specialist personnel.
•Observe the instructions given in the original Operating Instructions of the
subcontracted parts.
•If safeguards and tools are subject to wearing, they have to be checked
regularly and replaced, if necessary.
•For the replacement of cutting tools use the appropriate tool and suitable
protective equipment.
•After maintenance and cleaning works, it is definitely necessary to remount
the safeguards and to place them in their protecting position!
•Only use original spare parts from the manufacturer because these meet
the technical specifications and with this, the risk of accidents will be
minimised!
•Cleaning works with the high-pressure cleaner should be done in a way
that the water jet does not directly meet the bearing, rotating parts,
lubricating nipples, shaft sealing rings, wheel hubs, etc. After each cleaning
procedure with the high pressure cleaner, the lubricating points must be re-
greased. If this is not observed, the warranty claim will be rendered null
and void!
•After 5 operating hours and then regularly, check the screws and nuts for
tight fit and retighten them, if necessary.
•After maintenance mount the safeguards and place them in their protecting
position.
•If the machine is maintained, cleaned, or repaired in a raised position,
always secure it by suitable supporting elements.
When working on the electrical system, the earth strap must be removed from the
battery.
•If welding works are done on the machine, disconnect the battery.
•Repair works like welding, drilling, grinding, etc. may not be done on load-
bearing, safety-related parts.
•Before starting any repair works, make sure that the hydraulic system has
been depressurised, because pressurised fluids can penetrate skin and
cause serious injuries! Therefore, immediately consult a doctor - risk of
infection!
•Check hydraulic connections after 5 operating hours for the first time,
retighten if necessary!
Only re-tightening is not successful!
First release a leaky hydraulic screwed connection, then move hose or screwed
connection. After that, the screwed connection can be tightened again.
