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 does not have the click when second tongue is inserted then the buckle needs to
be washed or replaced. Contact our Customer Service Department 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. From the underside of the restraint pull each crotch 3-bar
slide then turn 3-bar slide and push through each slot to
remove the Harness Buckle from the restraint.
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.
C. Engage and disengage the Harness Tongues and Buckles
several times until a strong audible click is heard.
D. If you still cannot hear a strong audible click after
engaging the last Harness Tongues into Buckle,then repeat
cleaning several times. If the Harness Buckle cannot be
returned to its original working condition then contact
Britax Childcare Customer Service.
E. Refit the harness buckle to the restraint with the red button
facing out & feeding each 3-bar slide through appropriate
slot (see page 18).
