Interventions On The Machine - Mountfield MJ 66 Series Operator's Manual

6.2.1 Engine (Fig. 6.1)
Follow all the instructions in the engine manual.
The engine oil is emptied using a syringe (2) (at-
tachment on request) suited for that use, after
unscrewing the cap (1).
Fit a small pipe (3) of the right size and at least
400mm long on to the syringe (2) ; push the
small pipe (3) into the hole completely, then
suck all the oil out; please remember that this
operation has to be repeated a few times to
empty it completely.
6.2.2 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.
6.2.3 Battery (Fig. 6.2)
To ensure good performance of the battery it is
essential to keep it carefully maintained.
The battery must be periodically recharged us-
ing the battery-charger provided (if included).
The machine battery must always be fully
charged:
– b efore using the machine for the first time
after purchase;
– e very 20 starts of the engine;
– b efore leaving the machine disused for a long
period;
– b efore starting up the machine after a pro-
longed period of inactivity.
Carefully read and observe the battery recharg-
ing instructions in the booklet provided with the
battery. Failure in following the procedure or in
charging the battery could permanently damage
the battery elements.
A flat battery must be recharged as soon as
possible.
IMPORTANT Recharging must be done us-
ing a battery charger at constant voltage. Other
recharging systems can irreversibly damage the
battery.
The machine comes with a connector (1) for re-
charging; this is connected to the corresponding
connector for the special maintenance battery-
charger supplied (if included) or available on
request (see 8.2).
IMPORTANT This connector must only be
used for connection to the maintenance battery-
charger indicated by the Manufacturer. For its
use:
– follow the instructions given in the relative in-
structions manual;
– follow the instructions in the battery manual.

6.3 INTERVENTIONS ON THE MACHINE

6.3.1 Aligning the cutting-means
assembly (Fig. 6.3)
The cutting-means assembly should be prop-
erly adjusted to obtain an evenly mown lawn.
If mowing is uneven, check the tyre pressure.
If this is not sufficient to achieve an even cut,
please contact your Dealer to adjust the align-
ment of the cutting-means assembly.
6.3.2 Replacing the wheels (Fig. 6.4)
Stop the machine on flat ground and put a block
under a load-bearing part of the frame on the
side that the wheel is to be changed.
The wheels are held by a snap ring (1) which
can be removed 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; on
the contrary, you must adjust the cutting-means
assembly alignment to prevent uneven mowing.
IMPORTANT Before remounting the wheel,
apply grease to the axle. Put the snap ring (1)
and shoulder washer (2) back in place.
6.3.3 Repairing or replacing tyres
All puncture repairs or replacements will have to
be carried out by a tyre repair expert in accord-
ance with the methods for the kind of tyre used.
6.3.4 Replacing a fuse (Fig. 6.5)
The electric system and the electronic circuit
board are protected by a fuse. When it blows the
machine stops. In this case, remove the cover
(1) to reach the fuse (2) next to the battery.
The fuse capacity is indicated on the fuse.
IMPORTANT A blown fuse must always be
replaced by one of the same type and ampere
rating, and never with one of another rating.
If you cannot find out why the fuse has blown,
consult a Licensed Service Centre.
