Frame Latch - DAHON - SERVICE INSTRUCTIONS 2010 Service Instructions Manual

Frame Latch

The frame hinge is the most
important part of a folding bicycle.
Care should be taken to check
that the hinge is adjusted correctly
before each ride.
Your frame hinge will need periodic
adjustment. If there is play or
looseness in the frame it may need
to be adjusted. A properly adjusted
hinge eliminates play or looseness
and a correctly tightened hinge will
close with a strong seal, and the
frame will feel solid.
WARNING: If you are in
any way unsure of how to
make these adjustments
yourself, take your bike to a
qualified technician for
professional adjustment.
WARNING: Failure to
appropriately tighten the
frame latch can lead to damage
to the bicycle or injury to the
rider. Do NOT cycle with a loose
frame hinge.
Dahon uses a variety of frame
hinges on its bikes. Please check
your bike to see which of the
following instructions is applicable.

The ViseGrip™ Hinge (also
applies to the Eco frame's
hinge)
Use a 6mm wrench (if you do not
have the right sized wrench you
can also use an adjustable wrench
or small pliers) to tighten or loosen
the hinge.
Adjust the hinge bolt so that the
hinge opens and closes with the
correct amount of force which is
49~59 N for aluminum frames and
29~59 N for steel frames.
NOTE: Adjust in 1/16-turn
increments only, otherwise you will
quickly over-tighten or over-loosen
the hinge.
