BUCKLE OPERATION
To ensure the buckle remains operational the inside 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 the second tongue is inserted, the buckle needs to be washed
or replaced. The buckle is fully engaged when both tongues are inserted. 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 final harness tongue. 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 strap 3-bar
slide, turn the 3-bar slide on its side and push back
through the 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.
