  Note!
t  To fix the lower part of the air filter to the upper part or to the intake lines use production self-threading bolts. If these bolts are loosened or tightened with a power screwdriver, the thread in the upper or lower part of the air filter may get damaged.
t  Therefore, a power screwdriver may only be used in the following conditions:
t  maximum power screwdriver revs, 200 rpm
t  tightening torque set to 3 Nm, maximum
