Check Heating Fluid Level

Gradual fluid evaporation can occur, therefore, check
the level of heating fluid monthly.
1. Remove plug (6).
2. Place flexible object in port so that it protrudes
down. Pull out to observe level.
3. Refill heating fluid as necessary. See Fill Heating
Fluid, page 15, for instructions.

Check for Heating Fluid Leakage

When spray material is drained and heating fluid is full,
inspect the inside of the hopper for any signs of heating
fluid leakage.

pail directly beneath drain plug (37).
NOTE: Only 1-gallon (4-liter) pails fit beneath drain
plug if hoppers are mounted on the back of the
frame.
