Safety regulations for maintenance
Safety guidelines
No changes, modifications or additions may
be made to the tractor without approval from
the manufacturer.
DANGER
Incorrect inspection and maintenance procedures
can result in the malfunction of safety-critical com-
ponents.
Only carry out inspection and maintenance routines
if you have been trained, and are authorised to do
so.
DANGER
Do not make modifications to the drive or braking
parameters without informing the tractor drivers.
If modifications are made to the drive or braking
parameters, then it is imperative that drivers are
informed of such changes so that they are able
to familiarise themselves with the new operating
characteristics before taking the tractor into service.
DANGER
The majority of accidents and injuries that occur
in workshops are caused by the failure to observe
some basic rules of care and safety, and for this
reason, in most cases they can be avoided.
Follow the safety guidelines below, anticipate
potential hazards, and act with the necessary care
and caution to reduce the risk to a minimum.
An alert, cautious mechanic is a safe one.
– Tighten the parking brake before repair
work.
– Switch off the key switch.
– Disconnect the battery.
– Secure the front and rear wheels with wheel
chocks.
– Before electrical maintenance work or
checks, raise the drive wheels from the
ground and secure the truck with wheel
chocks.
– Always wear protective equipment (indus-
trial goggles and gloves) when working on a
battery.
– Always observe the required fire protection
measures when working on batteries.
– Always handle, charge and maintain
batteries according to the manufacturer's
instructions supplied with the battery.
– Always ensure that the lifting equipment
used has the required load capacity and
is certified accordingly. All blocks, jacks,
chains etc. are subject to regular checks
and must only be used for the purpose
intended.
– Only use marked lifting points for towing or
lifting. Attach the connections carefully.
Check that the pins/bolts provided are
secure before loading. Never stand close to
drawbars, slings or chains.
– Before releasing hydraulic connections,
ensure that the system is depressurised.
– Do not allow hydraulic oil under pressure,
for example at a leak, to penetrate the skin.
Medical aid is required if such an injury
occurs.
WARNING
Before working on or disconnecting any part of the
brake force booster system, the system must first
be depressurised.
Do this by actuating the foot brake twenty times with
the key switch turned off.
– Never wear rings, wrist watches, jewellery,
loose or dangling items of clothing such
as ties, torn clothing, scarves, unbuttoned
jackets or overalls with open zip fasteners
that could get caught up in moving parts.
Always wear approved safety clothing.
– Never carry out maintenance or servicing
operations on the tractor with anyone sat on
the seat, unless that person is fully trained
and involved in the operation being carried
out.
– Never switch on the tractor from any posi-
tion other than the driver's seat.
– The design of service steps or platforms
used for maintenance in the workshop or on
site must comply with current regulations.
