The MART Corporation Standard Turntable Power Washer v. 4.0
2.1.4. PBM Swivel (Inspect/Adjust)
Inspect the PBM swivel to be sure it is rotating freely.
Follow this procedure :
1. Turn the main power supply OFF .
2. Disconnect the PBM linkage from the PBM upper bearing/shaft .
3. Open the washer cabinet door.
4. Push the manifold back and forth. If it does not move freely, and if you have
been greasing the manifold regularly, you need to adjust the jam nut. The
jam nut is located on the swivel at the bottom of the PBM manifold. The
swivel assembly allows for take-up of the packing after it wears.
5. Swivels with Jam Nuts only: Adjust the PBM swivel jam nut so that it swings
freely, but is as tight as possible in order to prevent leaking around the joint.
Follow this procedure :
·
Remove the lock bar.
·
Screw the nut clockwise to the next locking slot (until compression on
the packing causes the nipple to rotate with a mild amount of torque).
·
Re-install the lock bar.
·
You may repeat this process until the packing has worn too badly to
keep a tight seal.
