Interventions On The Machine; Environmental Protection (Advice On Using The Machine In Ways That Respect The Environment) - EMAK MISTRAL 72/13 H Manual De Uso

Used oil must be taken in a sealed container to your
local service centre for reclamation. Do not throw it
in the rubbish bin or pour it down a drain, on the
GB ground or into the water system.
Rear axle
This is a sealed single unit that does not require maintenance.
It is permanently lubricated and its lubricant does not need
changing or topping up.
Carburettor
WARNING: Do not modify the carburettor. This could
lead to violation of exhaust gas emission laws.
Battery
To ensure long life to the battery it is essential to keep it
carefully maintained.
The machine battery must always be charged:
- before using the machine for the first time after purchase;
- before leaving the machine for a prolonged period of disuse;
- before starting up the machine after a prolonged period of
disuse.
Carefully read and comply with the procedure for recharging
described in the Battery chapter on page 23. If the procedure
is not followed or the battery is not charged, irreparable
damage could be caused to the elements inside the battery.
A flat battery must be recharged as soon as possible.
Recharging must be done using the special maintenance
battery charger supplied, which must be connected to the
corresponding red (+) and black (-) terminals on the battery.
For use follow the instructions given in the Battery charger
chapter on page 23.
Major servicing
It is advisable to have the machine inspected by a specialist
technician at an Authorised Service Centre at the end of each
season, if used intensively, or every two years in the case of
normal use.

7.4 Interventions On The Machine

Changing wheels
WARNING: Periodically check the condition and
pressure of the tyres; tyres that are in poor condition
or inflated to an incorrect pressure may affect the
machine's weight distribution.
Stop the machine on a flat surface and put blocks under a load-
bearing part of the frame on the side of the wheel to be
changed. The wheels are held by a snap ring (A, Fig.20) protected
by a cover (B), which can both be eased off with a screwdriver.
NOTE: If you have to replace one or both rear wheels, make
sure that any differences in their external diameter does not
exceed 8-10 mm.
Before remounting a wheel, apply grease to the axle. Carefully
refit the snap ring (A) and supporting washer (C). When
refitting the rear wheel ensure you also refit spacer (E) and
washer (D).
WARNING: Incorrect fitting of the snap ring may
cause the wheel to come off while the machine is
moving.
Repairing or replacing tyres
The tyres have inflatable inner tubes:
- front 11"x4.00"-4
- rear 15"x6.00"-6
32
All replacements or repairs following a puncture must be
carried out by a specialist tyre repair company.
Replacing a fuse
The machine has three fuses (G fig. 3) with different ratings,
the functions and specifications of which are as follows:
- 5 A fuse that protects the main and power circuits of the
electronic circuit board. When it blows, the machine stops
and the dashboard light switches off.
- 15 A fuse that protects the battery charger circuit. When it
blows, the battery gradually runs out and the machine will
have problems starting.
- 100A fuse protecting the starter motor; if this fuse blows
the engine cannot be started.
The fuse capacity is indicated on the fuse.
A blown fuse must always be replaced by one of the same
type and ampere rating, never one of a different rating.
If you cannot find the cause of the fuse blowout, contact an
Authorised Service Centre.
The fuses are housed under the cover (C); for removal and
refitting the cover see Connecting the battery on page 23.
Cutter assembly
The cutting deck should be properly set to obtain an evenly
cut lawn and reduce vibrations.
If the cut is uneven, check the tyre pressure.
Blade
WARNING
- Always wear work gloves to check the condition of the
blade.
- A damaged or bent blade must always be replaced.
Never repair a damaged blade by welding, straightening
or modifying it. This may cause the blade to come off
and result in serious or fatal injuries.
- Always use original marked blades (Fig.21).
- Check periodically that the bolt is tightened to 35 Nm
(3.5 kgm).
If the grass mowing becomes unsatisfactory as time goes by,
the blade probably needs to be sharpened. A badly
sharpened blade pulls out the grass and causes the lawn to
turn yellow.
- Sharpening the blade is a very delicate operation. If its
perfect balance is not taken into consideration, it can lead
to abnormal vibrations that cause the blade to become
loose, with consequent danger for the operator.
- The blade must be assembled with the right angle.
Erroneous assembly can cause incorrect tightening,
resulting in the loosening of the blade when working, with
dangerous consequences for the operator. For these
reasons the blade must be balanced and replaced by an
Authorised Service Centre.
8. ENVIRONMENTAL PROTECTION
Environmental protection should be a priority of considerable
importance when using the machine, for the benefit of both
social cohesion and the environment in which we live.
- Try not to cause any disturbance to the surrounding area.
- Scrupulously comply with local regulations and provisions
for the disposal of waste materials after mowing.
- Scrupulously comply with local regulations and provisions
for the disposal of oils, petrol, batteries, filters, deteriorated
parts or any elements which have a strong impact on the
environment. This waste must not be disposed of as normal
