How to Maximize Line Quality and Reduce Tip Wear. Observe the following suggestions to increase line quality
and minimize sprayer tip wear.
1. Select a larger tip orifice and run the sprayer at a reduced operating pressure.
2. Running larger tip sizes (example: use tip LL5321 @ 2000 psi instead of LL5317 @ 3300 psi) will significantly
increase tip life and reduce tip plugging. It will also produce a more uniform film build across the line.
