SETTINGS AND ADJUSTMENTS

Chain adjustment

Chain should be checked, adjusted and lubricated as per the "Maintenance
Chart (see Section B)" to ensure safety and prevent excessive wear. If the chain
becomes badly worn or is poorly adjusted (i.e., if it is too loose or too taut), it
3
could escape from sprocket or break.
Remove chain protective guards, as indicated in the corresponding paragra-
ph.
2 Position minicross onto a stand, and insert a 2÷5 mm dia. shim above upper
chain guide.
Adjust chain tension so as to allow shim slide without any forcing, and without
the chain being too slack.

If it is not, proceed as follows:
- Loosen hexagon nut (1).
- Loosen check nuts (2) on both sides.
- Turn screw (3), on both sides of rear swinging arm, to increase or decrease
chain tension, taking special care to centre wheel inside rear swinging arm
using the notches on swinging arm as a reference.
- Once the desired tension has been reached, lock rear wheel axle (4) with
4
hexagon nut (1) to the tightening torque of 80 Nm; 8 kgm; 59 ft/lb, and lock
screws (3) with check nuts (2).
With the chain fully tensioned, insert a suitable shim to check whether
chain is slackened. Should this be the case, contact a Husqvarna autho-
rised Dealer to have the chain changed.
