CARE & MAINTENANCE
BUCKLE OPERATION
To ensure the buckle remains operational the inside of the buckle must be kept free of liquids, sand,
dirt, fluff, food or similar substances. If the buckle is not operating or you do not hear a strong audible
click when second tongue is inserted then the buckle needs to be washed or replaced. Contact
Customer Service for assistance.
TO CLEAN HARNESS BUCKLE:
If sticky liquids such as baby formula, fruit juice, etc. get inside
your harness buckle, it may become sluggish. An indication of
a sluggish harness buckle is that you cannot hear a click when
engaging the harness tongues. To restore the harness buckle to
good working order it needs to be cleaned as follows:
A. Remove the harness buckle from the restraint: From the
underside of the restraint pull each crotch 3-bar slide then turn
the 3-bar slide and push through each slot.
B. Place the harness buckle under warm (max. 40 degrees
Celsius) running water as shown below. Let the water run
through the mouth of the buckle for five minutes. Check the
harness buckle is clean by engaging the harness tongues and
buckle several times until you hear a click.
C. If you still cannot hear a strong audible click then repeat the
cleaning process several times.
D. Refit the harness buckle to the restraint ensuring the red button
facing outwards and the 3-bar slide is fed through the same
slots.
If the Harness Buckle cannot be returned to its original
working condition then contact BRITAX Customer Service for
assistance.
