can cause damage to the sprayer components and the
environment. Unidentified chemicals left in the sprayer
tank can pose a serious health threat to anyone servicing
the unit and unaware of its presence!
Periodically clean and lubricate the pump chamber and
actuating linkage with a high quality lithium grease.
