KTM 990 - Manual (Page 41)

– When cleaning the motorcycle, do not use a high pressure cleaning unit if possible, otherwise water will penetrate the bearings, carbu-
retor, electric connectors etc.
– Do not use toothed washers or spring washers with the engine fastening screws, as these work into the frame parts and keep working
loose. Instead, use self-locking nuts.
– If you unscrew any screwed connections with self-locking nuts, they must be replaced when mounting. If no self-locking nuts are avail-
able, apply Loctite 243 to the thread. The screws and nuts must be replaced if the thread is damaged.
– All screws and nuts must be tightened to the specified torque figures using a torque wrench. If screws or nuts are not adequately tight-
ened, they can become loose and cause the motorcycle to go out of control while you drive. Tightening the screws and nuts too tightly
can damage the thread and components.
– Let your motorcycle cool down before beginning any maintenance work in order to avoid getting burned.
– Dispose of oil, grease, filters, fuels, cleaning agents etc. according to your local regulations.
– Under no circumstances may used oil be disposed of in the sewage system or in the open countryside. 1 liter used oil contaminates
1,000.000 liters water.
