|648744 brake bleeder
Just bought the model #648744 on man bleeder from advanced auto parts. The instructions are missing. Is there some place on your web site to download a new set of directions. Thanks for any help you can give.
Vacuum Pump mInstructions
I would make sure that the front collar is being slide forward
or back fully (see attached). Place a finger over the nozzle and see if
vacuum or pressure is created by pumping. If there is no vacuum or
pressure I would then check the o-ring under the collar to see if they
are worn. Replace o-ring if necessary. Other than that there is no other
serviceable parts and the unit is sealed with thread lock so checking
the internal valving is not possible.
