SECTION 4
Routine Maintenance
4.1 MAINTENANCE
We here below describe the maintenance and
adjustment operations. A low operating cost and a
long life of the machine depend also on a
methodical and constant compliance with these
instructions.
The operations of maintenance, adjustment
and preparation for working shall be carried
out when the engine is off and when the
machine is locked.
Use original spare parts only.
In this way the warranty terms will not be
declared void and the technical specifications
of the machine will not be changed.
4.2 MAINTENANCE OF THE CUTTER
BARS
- Stop the engine before any cleaning and
maintenance operation.
- Make sure that all the nuts, screws and bolts
are perfectly tightened, so that the safety
conditions are complied with.
- Make sure that all teeth and the blades are
straight.
- Replace the damaged or worn parts whenever
necessary (knife clips, knives, blades, wearing
plates).
- After mowing, wash and clean the cutter bar and
remove the dirt (if necessary, extract the knife).
- Periodically check that the knife clip is adjusted
properly (make reference to the manual of the
cutter bar).
- Use original spare parts only, for any
maintenance and adjustment operation. In this
way the warranty terms will not be declared void
and the technical specifications of the machine
will not be changed.
4.3 CUTTER BARS WITH OIL-BATH
MOVEMENT
Check the oil level according to the type of
gearcase (Fig. 10 - 11).
Before using the machine, check the oil level in
the gearcase and, if necessary, top it up. The oil
level shall be checked as follows:
- Position the cutter bar on a flat surface.
- Unscrew the screw plug (2). When the oil
reaches the lower edge of the hole, the oil level
is correct.
- If necessary, top it up through the hole (1) with
oil EP 320 (IT IS NOT NECESSARY TO
CHANGE THE OIL COMPLETELY).
- Then screw the plugs again.
Warning! Periodically check the seals (3) and
(4). If they are loose, they might leak.
Moreover, make sure that the sleeve (8) is in
perfect working order and that it is not damaged.
Before inserting the attachment in the housing of
the machine power take off, grease the part 7 (Fig.
10) and the part. 6 (Fig. 11) of the sleeves.
If your cutter bar is the one shown in Fig. 11,
periodically grease part (5) with multipurpose
lithium-based grease.
4.3.1 LUBRICATION
The lubrication is an easy operation but it is
necessary so that the moving parts are not
damaged.
- Every 2 or 3 working hours (always when the motor
is off) we suggest to lubricate or grease the knifes
in their slides or guides (as shown in Fig. 8).
4.3.2 KNIFE SHARPENING
We suggest to sharpen the knife every 3 - 5 working
hours or as soon as you notice that they are worn
out; this, however, depends on how often you use
the attachment and how you use it.
Before sharpening the knife, remove it from the
cutter bar and clean it.
Warning! Use protective gloves.
Make sure that the blade-holding rod (5) (Fig. 5 -
6) and the blades are not damaged or deformed
because of some impacts. If so, it is necessary to
straighten or replace them. Check also the
counterknife blades. We remind you, in fact, that
you get the best cutting only when the knife
perfectly adheres to the counterknife. Now it is
possible to sharpen the knife by means of a
grinding wheel. Pay attention not to change the
original sharpening angle of the single blades, by
sharpening the blades starting from the bottom to
the tip (see Fig. 9).
The same operations shall be carried out to
sharpen the counterknife, but less frequently.
