Seatpost; Brakes - Tern Quick Haul D7i Bedienungsanleitung

6.B. Seatpost
Some bikes are equipped with a cam action seatpost binder. The seatpost cam action binder works exactly like
the traditional wheel cam action fastener (6.A). While a cam action binder looks like a long bolt with a lever on
one end and a nut on the other, the binder uses an over-center cam action to firmly clamp the seatpost (fig. 16).
WARNING: Riding with an improperly tightened seatpost can allow the saddle
to turn or move and cause you to lose control and fall. Therefore:
1. Ask your Dealer to help you make sure you know how to correctly clamp your seatpost.
2. Understand and apply the correct technique for clamping your seatpost.
3. Before you ride the bike, first check that the seatpost is securely clamped.
Adjusting the Seatpost Cam Action Mechanism
The action of the cam squeezes the seat collar around the seatpost to hold the seatpost securely in
place. The amount of clamping force is controlled by the tension adjusting nut. Turning the tension
adjusting nut clockwise while keeping the cam lever from rotating increases clamping force; turning it
counterclockwise while keeping the cam lever from rotating reduces clamping force. Less than half a
turn of the tension adjusting nut can make the difference between safe and unsafe clamping force.
WARNING: The full force of the cam action is needed to clamp the seatpost securely.
Holding the nut with one hand and turning the lever like a wing nut with the other hand
until everything is as tight as you can get it will not clamp the seatpost safely.
WARNING: If you can fully close the cam lever without wrapping your fingers around the seatpost or a
frame tube for leverage, and the lever does not leave a clear imprint in the palm of your hand, the tension
is insufficient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again.
INFO: Some bikes are equipped with telescoping seatposts that have two cam action mechanisms.
6.C. Brakes
Tern Pedelecs primarily use disc brakes, which operate by squeezing a hub-mounted
disc between two brake pads. Internal hub brakes may also be used. Please consult your
Pedelec's QuickStart Guide and any other documentation included with your bike for
more information. Both can be operated by way of a handlebar mounted lever.
WARNING:
1. Riding with improperly adjusted brakes, worn brake pads, or wheels on which the
rim wear mark is visible is dangerous and can result in serious injury or death.
2. Applying brakes too hard or too suddenly can lock up a wheel, which could cause
you to lose control and fall. Sudden or excessive application of the front brake may pitch
the rider over the handlebars, which may result in serious injury or death.
3. Some bicycle brakes, such as disc brakes (fig. 20) and linear-pull brakes (fig. 21), are extremely powerful.
Take extra care in becoming familiar with these brakes and exercise particular care when using them.
4. Disc brakes can get extremely hot with extended use. Be careful not to
touch a disc brake until it has had plenty of time to cool.
5. See the brake manufacturer's instructions for operation and care of your brakes,
and for when brake pads must be replaced. If you do not have the manufacturer's
instructions, see your Dealer or contact the brake manufacturer.
6. If replacing worn or damaged parts, use only manufacturer-approved genuine replacement parts.
6.C.1. Brake Controls and Features
WARNING: It's very important to your safety that you learn and remember which brake lever
controls which brake on your bike. In many countries, the right brake lever controls the rear
brake and the left brake lever controls the front brake; but this is not true for all countries. So
before riding, check to see how your bike's brakes are set up, squeeze one brake lever and look
to see which brake, front or rear, engages. Now do the same with the other brake lever.
Make sure that your hands can reach and squeeze the brake levers comfortably. If your hands
are too small to operate the levers comfortably (fig. 23), consult your Dealer before riding the
