E. MAINTENANCE
E.1 Warnings during maintenance
The hay tedder is agricultural equipment that
does not require special maintenance, nor
relative programs. However, there is a regular
intervention, described below, which, if done with
care by the Client, will keep unchanged the
efficiency and the working capacity of the
machinery avoiding any operating damage.
The operator, which must be of age, qualified and
trained to perform such interventions must
necessarily observe what follows:
HAZARD
- any type of intervention has to be
performed on a flat surface, sufficiently
lit and clear of people, animals or things
that might hinder the manoeuvre. The
equipment must be placed firmly on the
ground, the tractor blocked, the parking
brake pulled, the engine switched off and
the ignition key removed from the
dashboard. Should it be necessary to lift
the hay tedder, it is appropriate to secure
it by placing beneath pieces of wood or
metal, as shown in figure
;
- before operating, for his safety and to
prevent damage to the hay tedder, he must
apply, well in view on the tractor dashboard,
the
warning sign " Machine under
Maintenance
”;
-
both maintenance and repair operations,
once started, must always be finished and
never postponed;
-
he must rely on his memory, but always read
the instructions in this manual and execute
them accurately;
-
the use of equipment to perform
maintenance work is subjected to the
accident prevention.
At the end of maintenance or repair operations,
remove from the area any water, oil, grease oily
rags, tools or other material that may be present.
E.2 Maintenance tasks
The intervention times are for information only
and refer to normal conditions of use. Therefore,
they are subject to changes in relation to the kind
of service, the environment in which the work is
done (more or less dusty) seasonal factors etc.
The more
the machinery conditions are
burdensome, the more the interventions must be
increased.
The maintenance tasks to be performed every
week or after 40 operating hours are:
-
refuelling of grease by using the specific
pump, in all the grease nipples present on the
equipment and identifiable through the
adhesive labels like the one shown on the side
and sticked in their proximity. Grease agip MU
EP 2;
-
check the fastening of nuts and screws that
secure the various parts of the equipment;
-
check for the presence of the various safety
pins and R cotter pins that lock the various
parts of the equipment;
-
verify that the structural integrity of all the
equipment parts especially those more
subject to wear such as wheels tires;
-
check the integrity of the rotary units and that
the transmission gear box does not present
any oil leakage.
Note: all types of hay tedder have an oil
immersed transmission gear box which
means that all internal components operate
immersed in the lubricant..
Consequently, they are subject to a rapid
wear out if the oil runs out and therefore to
seizure. Therefore, if from the box any loss
or leakages are to be verified, it is essential
to check the inside oil level.
To check simply unscrew the cap level on
the side of the head as shown in the figure. If
the oil level does not reach the bottom of the
hole, its quantity is to be considered
insufficient and its refilling must be operated
through the same hole until the oil begins to
overflow.
