WARNING!
In case of contact with the skin or eyes, rinse
thoroughly with clear water. Seek medical attention imme-
diately when necessary. Always keep the battery and acid out
of the reach of children.
WARNING!
Measures taken for the application of Direc-
tive 2006/66/EC relating to the marketing of batteries and ac-
cumulators containing certain hazardous materials and their
elimination.
ELIMINATION OF BATTERIES
Batteries contain hazardous materials and must under no circumstances
be disposed off into the environment. They are the subject of specific
rules governing their elimination. For the disposal of batteries marked
ETESIA, we participate in the schemes in place in the countries where
the machine is sold.
WARNING!
Batteries kept in a discharged state cannot
subsequently be recharged and are not covered under the
terms of the warranty.
7•4 MAINTENANCE OF THE TYRES
• Always ensure that the tyres are inflated to the recommended pres -
sure. Different pressures from these those recommended may adver-
sely affect driving performance and may even result in loss of control
of the ride-on brush-cutter.
- Front tyre pressure : 1,2 bar
- Rear tyre pressure : 1,0 bar
DISPOSAL OF USED PNEUMATICS
It is forbidden to dispose off, to lay down or to burn pneumatics in
nature. Our dealer network has been informed about its obligation to
take back, free of charge, all used pneumatics from ETESIA ride-on
brush-cutters.
7•5 MAINTENANCE OF THE BLADE
WARNING!
Before carrying out any work on the cutting
mechanism, always switch off the engine and remove the
ignition key. Protective gloves should also always be worn.
7•5•1 CUTTING UNIT (BLADE) CONDITION
• Blade condition must be checked for any damage or wear every time
ride-on brush-cutter is used (picture 19). The blades wear quickly when
you work on dry or sandy ground.
• If a blade is blunt or twisted, cutting quality will suffer. A damaged
blade can be very dangerous if a piece falls off and is ejected from
cutting unit housing.
• Change any worn or damaged blade immediately (see 7•5•3).
• Replace the damaged blades and fixation bolts by complete set in
order to keep the cutting device balance.
• Check the knife holders on the blade. Even of the knife holders are
not bent or worn, they must be replaced every 100 hours or every 2
years of use.
• We recommend buying spare blades and blade setting nuts in ad-
vance and keeping them close to hand.
• When the head of the nut (picture 20) of the knife is worn, this can
cause serious accidents (the knife may, for example, be propelled by
centrifugal force). Replace the blade nut immediately when the tooth
has disappeared. In addition, replace (or invert) the knife when it is
worn to 30% (picture 20).
• After sharpening, check the coupling and the state of the cutting device.
• If significant damage is noticed on cutting unit housing, a more de -
tailed examination of the complete system should be carried out by
your Dealer.
IMPORTANT !
For re-assembly of blade unit refer to pic-
tures 21 and 22.
7•5•2 DISMANTLING CUTTING SYSTEM
• Stop engine and remove key from ignition. Before proceeding with
dismantling, protect your hands with work gloves.
• Engage parking brake.
• Put the cutting height lever in the transport position (highest) to dis-
assemble the two springs A (right and left) of the chassis (see picture
23a).
• Place 2 wedges (across the entire width of the cutting deck) with a
height of more than 60 mm (see picture 24) to lay the cutting deck.
• Lift the seat support assembly to access the elements above the cutting
deck. Disassemble the belt guard B (3 screws) (see picture 23b).
• Loosen the two anti-jump tabs C in order to remove the D-belt from
the pulley E (see picture 23b).
• Disassemble the clutch cable + blade brake F from the frame (see
picture 23b).
• Remove the four V-rings G from the two front arms of the cutting
height lever H and completely disassemble the two H-arms (see pic-
ture 23c).
• Remove the four V-rings I and the two beta pins J to completely dis-
assemble the rear arms K from the cutting height (see picture 23a).
• Disengage cutting system from ride-on brush-cutter.
For re-assembly, proceed in reverse order.
7•5•3 CHANGING CUTTING UNIT (BLADE)
• Blade may be checked and removed via deflector on right-hand side
of cutting unit housing.
• To change cutting unit, the ideal method is to dismantle cutting sys-
tem (see dismantling cutting system §7•5•2).
• Unscrew central screw to take off complete blade with coupling.
• Tighten blade screw to 50 Nm.
• Mount blade in such a way as to direct cutting edge towards ejection side.
7•5•4 BLADE REPLACEMENT (PICTURES 19
TO 22)
• The blades are reversible. Simply turn them through 180°.
• Swing deflector on right side of casing upwards.
• Wrap a cloth around cutting edge.
• Block beam with a steel rod Ø 10 mm.
• Unscrew nut (1) then take out Jappy screw (2) (picture 22).
WARNING !
Take care not to lose spacer and washers.
For re-assembly, proceed in reverse order.
7•6 BRAKE ADJUSTMENT
ADJUSTMENT OF FRONT BRAKE (EXCEPT
AK98X) (PICTURE 25)
• Front brake is inside of front wheel (right and left). Adjust by brake
wire on it.
• Front brake should be adjusted at brake wire nut fixing point to lock
front wheel when brake pedal is stepped (pedal is locked).
