5.2 ENGINE MAINTENANCE
As for the engine maintenance, make reference to the
specific engine instructions manual. Approximately,
every 8 working hours: check and top the engine oil
level up, if necessary. Check, moreover, the engine
air filter and clean it if necessary.
Every 50 working hours, replace the engine oil.
5.3 MACHINE MAINTENANCE
Periodically wash the machine and clean thoroughly
each part. If a high pressure washing system is used,
check that the fuel does not get wet and that no part
is damaged. After each washing, it is necessary to
lubricate all parts subject to friction.
At least once a year, if there are not visible oil leaks,
check and top up the hydraulic system, if necessary (
in the machines with a dumping hydraulic system).
The correct oil level is obtained when the oil level
reaches the“oil level” mark on the transparent plastic
tank (5 Fig. 6).
5.3.1 PRIMARY TRANSMISSION
(SPEED CHANGE UNIT)
(
Reference Fig. 7).
The primary transmission and the change gear is a
group of elements transmitting motion from the driv-
ing shaft for the forward speed (AM) to the driven
pulley (P) and from the snub pulley for the reverse
speed (AR) to the driven pulley (P).
The motion is transmitted by engaging the pulleys L
and P for the 1st speed; and L with P2 for the 2
nd
speed; for the reverse speed, instead, the pulleys R
with P3 are engaged.
The pulleys P1-P2-P3-P4-P5 are integral among them
and they form the P pulley with 5 grooves (races).
In order to engage the 1st speed, it is necessary to
actuate the control lever on the handlebar that, by
bringing the G1 guide pulley near the pulley, tensions
the same and transmits the power from A to P.
In order to engage the 2nd speed, it is necessary to
actuate the control lever on the handlebar that, by
bringing the G2 guide pulley near the pulley tensions
the same and transmits the power from R to P.
If an adjustment is required, perform the following
procedure, after shutting the engine off and remov-
ing the belts guard.
The F belt-braking system of the 1st and 2nd speed,
is fixed to the machine in the K and Q points and it
has holes bigger than the fastening screws so that it
may be adjusted by moving upward, downward, right-
ward and leftward and slightly rotate.
To adjust this parts do as follows:
1) With the wrench 17 loosen the hexagon nut placed
in K, then move the belt-braking system so to
obtain the following two conditions:
a) The distance X between the belt-braking sys-
tem and the pulley P (Fig. 8) shall be included
between mm 1 and 2.
b) The distance Y between the belt-braking sys-
tems F and the belt with the Q1 rod tensioned
(1
st
speed lever actuated) must be included
between mm 1,5 e 2,5.
2)
After complying with the conditions a) e b)
tighten the nut in K, by making sure that the belt-
braking system does not move during this op-
eration (if necessary use some pliers or another
instrument)
After adjusting the belt-braking system in this way,
reassemble the belts guard, start the engine and op-
erate and release the levers (1st, 2nd and reverse)
separately and check that the belts stop completely.
This happens only if you do not hear squeaking or
noises. If so, you must repeat the adjustment by pay-
ing more attention.
5.3.2 ADJUSTMENT OF THE FEED CONTROL
LEVERS
The adjustment of the feed control levers is very im-
portant because they control the guide pulleys en-
gaging the speeds that, by tensioning the several belts,
make the machine move.
A correct adjustment of the feed control levers and of
the reverse is obtained by making sure that the springs
M1-M2-M3 Fig. 9 lengthen of mm 25
÷
28 when the
respective control levers placed on the handlebar are
operated till the end of the stroke (as a support to the
knob).
In order to obtain this, operate on the forks F1-F2-FR
Fig. 9. if necessary.
N.B: While the machine is being used, the feed con-
trol levers must always be operated till the end of
the stroke (as a support to the rubber knob).
5.3.3 BELT ADJUSTMENT FOR REVERSE
In case of a belt replacement or in case it is neces-
sary to adjust the belt reversing the motion (belt con-
necting AT with
AR) act in the following way:
- Unloose the fastening screw of the AT cam on which
the bearing is assembled.
