WARNING!
Remove all chemicals and wash before storing the
sprayer. Chemical products have different reactions and
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.
