Birchmeier 10517301 Grease
One of the most important things you can do to extend the life of your backpack is to keep it properly lubricated. This grease is custom formulated for your Birchmeier backpack. Two 1 oz. jars.
We have seen many technicians force pump their backpacks without grease. What usually happens is either the pump handle snaps off at the threads or the steel frame breaks where it connects to the tank. Birchmeier will NOT warranty these situations. GREASE YOUR BACKPACK! If you are the owner or supervisor, inspect your technician's backpacks to ensure proper lubrication.
