Read page 34 (MAINTENANCE) care-
fully.
The vehicle is provided with a single-unit
chain, in which the main joint is not used.
An excessive slackening of the
chain can cause its coming out
of the pinion, which often results
in accidents or serious damages to the
vehicle. Periodically check the slack
and if necessary adjust it, see p. 41
(ADJUSTMENT). To change the chain,
contact your
DSULOLD
Official Dealer,
who will ensure you careful and prompt
servicing.
If maintenance operations are
not carried out properly, the
chain may wear untimely and/or
the pinion and/or the crown may be
damaged.
CHECKING THE SLACK
To check the slack, proceed as follows:
◆
Stop the engine, position the vehicle
on the side stand and put the gears
into neutral.
◆
Make sure that the vertical oscillation,
in an intermediate point between pi-
nion and crown in the lower branch of
the chain, is about 20 ÷ 25 mm (Fig.
33).
◆
Move the vehicle forward, in such a
way as to be able to check the vertical
oscillation of the chain also when the
wheel turns; the slack must be con-
stant in all the wheel rotation phases.
If in some sections the slack is greater
than in others, this means that there
are crushed or seized links.
To eliminate the risk of seizures, lubri-
cate the chain frequently, see p.
41(LUBRICATION AND CLEANING).
If the slack is uniform, but exceeds
20 ÷ 25 mm, carry out the adjustment,
see p. 41 (ADJUSTMENT).
