OPERATION
4.2.2. CHAIN DRIVE UNITS
At delivery, the chain is optimally tensioned and must not be re-tensioned,
neither after the prolonged use of the drive. The chain is continuously sub-
mitted to tensile load by muscle and motor power. This will extend it over
time. Optimal chain tension is maintained by the chain tensioner which also
prevents the chain from sagging. However, check the chain at a specialist
worksite at regular intervals by, since a worn-out chain will damage the chain
ring and sprocket.
4.3. BRAKE SYSTEM
Your Ruffian is equipped with hydraulic brake discs for a fast and safe stop-
ping action. Use both brakes simultaneously for an optimal and safe braking.
The left brake lever has an effect on the front wheel brake, the right brake
lever has an effect on the rear wheel brake.
The brake system is provided with a fully automated lining compensation.
This offsets the wear of the brake pads, while the brake pressure point re-
mains equal.
The front wheel brake has a stronger delay effect than the rear
wheel brake. Exercise the purposeful use of the front wheel brake,
so that you become familiar with its force.
If you force too much the front wheel brake, a hazard of tipping over
exists. Your rear wheel might lift and have you fall over the handlebar.
-> Pull a little less at the left brake lever, or fully release the brake
lever, when you notice that the rear wheel is lifted.
After braking, specially after long rides down the hill, the brake discs,
brake calliper and quick release and axis nuts can become very hot.
-> Do not touch the brake discs after intense braking action. You
could burn yourself.
