Wheels - Tern Quick Haul D7i Bedienungsanleitung

fig. 19
It is very important that you understand the type of wheel securing method on your bicycle,
that you know how to secure the wheels correctly, and that you know how to apply the correct
clamping force that safely secures the wheel. Ask your Dealer to instruct you in correct front
wheel removal and installation, and ask for any available manufacturer instructions.
DANGER: Riding with an improperly secured wheel can allow the wheel to wobble or fall
off the bicycle, which can cause serious injury or death. Therefore, it is essential that you:
1. Ask your Dealer to help you make sure you know how to install and remove your front wheel safely.
2. Understand and apply the correct technique for clamping your wheel in place.
3. Each time, before you ride the bike, check that the wheel is securely clamped.
The clamping action of a correctly secured wheel must emboss the surfaces of the dropouts.
Front Wheel Secondary Retention Devices
Most bicycles have front forks that utilize a secondary wheel retention device to reduce the
risk of the wheel disengaging from the fork if the wheel is incorrectly secured. Secondary
retention devices are not a substitute for correctly securing your front wheel.
Secondary retention devices fall into two basic categories:
1. The clip-on type is a part that the manufacturer adds to the front wheel hub or front fork.
2. The integral type is molded, cast or machined into the outer faces of the front fork dropouts.
Ask your Dealer to explain the particular secondary retention device on your bike.
DANGER: Do not remove or disable the secondary retention device. As its name implies,
it serves as a back-up for a critical adjustment. If the wheel is not secured correctly, the
secondary retention device can reduce the risk of the wheel disengaging from the fork.
Removing or disabling the secondary retention device may also void the warranty.
DANGER: Secondary retention devices are not a substitute for correctly securing your
wheel. Failure to properly secure the wheel can cause the wheel to wobble or disengage,
which could cause you to lose control and fall, resulting in serious injury or death.
Wheels With Cam Action Systems (Quick Release System)
There are currently two types of over-center cam wheel retention mechanisms: the
traditional over-center cam (fig. 16) and the cam-and-cup system (fig. 17). Both
use an over-center cam action to clamp the bike's wheel in place.
Adjusting the Traditional Cam Action Mechanism
The wheel hub is clamped in place by the force of the over-center cam pushing against one dropout
and pulling the tension adjusting nut, by way of the skewer, against the other dropout. 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 clamping force and unsafe clamping force.
WARNING: The full force of the cam action is needed to clamp the wheel 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 a cam action wheel safely in the dropouts. See also the first WARNING in this Section.
Adjusting the Cam-and-Cup Mechanism (fig. 17)
The cam-and-cup system on your front wheel will have been correctly adjusted for your bicycle by
your Dealer. Ask your Dealer to check the adjustment every six months. Do not use a cam-and-
