WARNING !
Drive the machine (forward - reverse) and
check the level. The level has to be between the [UP] and
[LOW] marks. If necessary, to up.
• Dispose used oil in an approved collection point.
7•2•2 HYDROSTATIC UNIT OIL CHANGE OR
REFILL (AK98X)
• Stop the engine for oil change or checks.
• Park the machine on a flat and horizontal area.
LEVEL CHECK
• Check the oil level when the system is cold. The level can be checked
from the rear of the machine at the reservoir (b picture 14) using the
level indicator (c picture 14).
• First oil change : after 15 hours
• Next changes : every 100 hours or once a year
• Recommended oil : HV 46 (ref. : 29592 - 2 liters)
OIL CHANGE
• Remove the rear part of the chassis.
• To drain the oil from the hydraulic unit on the rear axle, undo the
screw (a picture 15).
• To drain the oil from the hydraulic unit on the front axle, undo the
screw (a picture 14 bis). Allow the oil to drain, then re-tighten the
draining screws (not completely).
TO COMPLETE THE OIL LEVEL
• Raise the machine at the rear so that the tank is the highest part of the
hydraulic circuit.
• Fill the hydrostatic unit by the tank.
• Poor the oil slowly to avoid trapped air in the unit which could make
the restart harder.
• When oil starts to emerge from the front purging screw (a picture 14
bis), tighten it completely.
• Continue filling the tank until oil emergences from the rear purging
screw (a picture 15). Tighten the purging screw completely. Put a
little more oil in the tank.
• Place the machine horizontally again. According to the case, to ob-
tain the right oil level, top up or purge.
• Lift the machine off the four wheels using four jack stands (observing
the safety rules so the machine is stable) to check the functioning of
the wheels (let the engine tick over).
• Move the drive lever fully in both drive direction, keeping the lever
for 5 seconds in each position. Repeat this operation twice.
• Check that no bubbles appear in the tank during this operation.
• After these operations, top up the oil if necessary to the level indi-
cated on the tank.
7•2•3 TRANSMISSION GEARBOX OIL CHANGE
OR REFILL
• Stop the engine for oil change or checks.
• Place the machine on a flat and horizontal area.
• Check the oil level when the system is cold. The level should reach
the lower limit of the gauge and can be checked by unscrewing the
gauge (picture 17).
• First oil change : after 15 hours
• Subsequent changes : every 100 hours or once a year
• Recommended oil : SAE 90 or CKT 220 (ref. : 29590 - 1 liter)
• Capacity : 1 L.
• To change gearbox oil, unscrew the drain plug (a picture 17 bis). Let
the oil flow and tight the drain plug.
• To refill, unscrew the oil level gauge (picture 17) and fill with oil
through this opening.
WARNING !
When the machine is on a flat horizontal sur-
face, the level shoud not exceed the lower limit of the gauge.
• Dispose used oil at an approved collection point.
7•3 MAINTENANCE OF THE BATTERY
7•3•1 FRONT COVER REMOVAL AND ACCESS
TO THE BATTERY
To remove the front cover or for access to the battery, the front bum-
per (picture 18) must be removed by loosening the 2 screws (a picture
18). Open the ¼ turn of the front cover (b picture 18) and remove the
front cover by pulling it out of the 2 notches of the chassis. Now you
can mount or remove the battery by removing the retaining bracket
(a picture 18 bis) using the 2 rods (b picture 18 bis) and the 2 nuts (c
picture 18 bis).
7•3•2 MAINTENANCE OF THE 12 V BATTERY
• The 12 V battery is located under the front cover.
• This lead-acid battery requires very little maintenance.
• The level of the electrolyte should be checked every 50 hours, and
should always lie between the upper [Max] and lower [Min] level
markers. The level of the electrolyte in the cells can be checked wit-
hout removing the battery, by opening the front cover.
• If the electrolyte level of a loaded battery is close to the minimum
marker, add distilled water up to the level of the maximum marker.
Never overfill the battery or add acid.
• Check that the battery terminals are not oxidized.
• If necessary, clean the terminals and coat with special battery grease.
WARNING!
If, for any reason, it is necessary to disconnect
the battery, always disconnect the negative terminal first, fol -
lowed by the positive terminal.
• In case of overfilling of the battery when topping up, rinse the affec -
ted areas thoroughly to prevent corrosion.
7•3•3 CHARGING THE BATTERY
WARNING!
Remove the battery from the ride-on brush-
cutter by disconnecting first the negative terminal and then the
positive terminal.
• Check the electrolyte level. If necessary, top up with distilled water.
• Wear the individual protection equipment’s that are necessary while
making the maintenance of the battery (safety glasses and gloves…).
• Connect the battery to the charger.
- Charge voltage : 12 V
- Charging current : max.16 A
- Charge time : up to 12 hours, according to need
Lead-acid batteries emit explosive gas mixtures during char-
ging. Avoid naked flames and sparks and do not smoke. The
battery should always be charged in a well-ventilated area.
The battery contains sulphuric acid which is highly dangerous
and liable to cause serious injury upon contact with the skin.
Extreme care should therefore always be taken.
