• Wear protective clothing, gloves, and eyewear.

Cleaning Solvent Hazard with Plastic Parts

Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious injury or property damage. See Technical Data on page 19 of this instruction manual and in all other equipment manuals. Read fluid and solvent manufacturer’s warnings.

Warnings

CAUTION

Water or material remaining in unit when temperatures are below freezing can damage motor and/or delay pump startup.

To insure water and material are completely drained out of unit:

1. Remove material line from sprayer.

2. Tip sprayer up as shown. Before adding material or starting unit in cold weather, run warm water through pump.

Install burp guard (J) before adding material to hopper. When only a small amount of material remains in the hopper, the burp guard prevents material from shooting out when the sprayer is turned off. This material could splash into the operator’s eyes or skin.
