The belt rake is easy to maintain. In order to prolong its life period we recommend that
you take into consideration the following:
5.1 Stretching and maintenance of the belts
V-belts should be properly stretched. Check the tension of the belts after first few hours
of operating. Stretch them if needed. The belt is properly stretched when it does not yield more
than 2-2.5 cm if pressed by a hand. The belt is to be stretched as follows:
a) Loosen the fastening screws (fig 1, pos.14).
b) The driving belt (fig.1, pos.4) is to be stretched with the help of stretching screw (fig.1,
pos.11). If the belts of the raking system (fig. 1, pos.6) get too stretched, you have to
loosen the stretching screw of the belts of the raking system (fig.1, pos.12).
c) The belts of the raking system (fig.1, pos.6) are to be stretched with the help of
stretching screw of the raking system (fig. 1,pos.12). Make sure that the drive belt (fig.1.
pos.4) stays properly stretched.
d) When the belts are properly stretched, tighten the fastening screws (fig.1, pos.14).
V-belts must be cleaned from time to time and lubricated with glycerin to keep them
flexible.
5.2 STORAGE AND LUBRICATION
The P.T.O Shaft should be lubricated every 10 working hours with grease.
Slide bearings on wheels should be lubricated with grease once a year.
After the season the machine should be thoroughly washed, dried and lubricated with an
oily rag. The belts should be lubricated with glycerine and released.
Slide bearings on the belts do not require any lubrication, but if the machine is left
unused for a long period of time, a layer of corrosion is formed that is much harder than
plastic , so prior to each season those spots should be lubricated with oil or grease.On
this occasion, the rake should be put into operation for a few minutes, so that the grease
could penetrate into the bearings.
Roller bearings do not need to be lubricated because these bearings are pre-lubricated
and sealed for dust and water
The machine should not be stored near mineral fertilizers and plant protection products
due to aggressive environment.
5.3 Tyre maintenance
You should regularly control the tyre pressure and keep it at 2.0 bar.
5.4 PERIODICAL OVERHAULS
The rake should thoroughly be overhauled every year. Occasional overhauls are
recommended before use.
The overhaul consists of:
• The examination of the tension of the raking system;
• The examination of the spring tines fastening;
• Pressure examination;
• Lubrication according to the instructions for lubricating and maintenance.
