Congratulations on the purchase of your new GIANT CONTACT SWITCH

situations and ultimately help you enjoy your rides. When used properly, this
product will provide years of use.
Precaution
Please read the instructions thoroughly before installation and using this

1. Adjusting the position of the saddle height during riding can cause the loss
of control.

worn. Do not modify the Contact Switch seatpost; any modifications will
void the warranty, and could cause invisible damages to the seatpost
and/or the seatpost malfunctions.
3. Loose, over tightened, damaged, or worn parts may cause unexpected
malfunction. Periodically check the seatpost for wear or damage. If there
are any indications of wear, cracks, or dents shown on the seatpost or any
of its parts, stop using the seatpost immediately and find an authorized
GIANT dealer for inspection, repair or replacement of the parts.
4. Please check that all bolts on the Contact Switch seatpost have been
properly fastened within the recommended torque settings before you ride
the bike.
5. Over tightening the seatpost clamp will affect the height-adjustment
functionality of the seatpost, please find the recommended clamping torque
etched on the seatpost clamp or in the bicycle user manual.
