Before You Start
10. Place reservoir into backpack. NOTE: The air compressor always needs to be on while the sprayer is
in operation (if the light is on, the air compressor is
on). If fluid level is at half or less, allow up to 2 minutes for reservoir to pressurize before initial use.
11. Pull strap until reservoir is firmly secured into backpack.
13. Place backpack system on operator. You are now
ready to spray!
NOTE: If the tip needs to be changed while spraying, be
sure to follow Pressure Relief Procedure (see sprayer
manual). Turn air compressor off and slowly remove
from lid assembly. This will ensure pressure is released
from reservoir before changing the tip.
System is now pressurized. Failure to properly
depressurize system will result in material discharging
from hose and possible injury.
Always turn off and slowly remove air compressor from
lid assembly to depressurize system before removing:
• Hose set from sprayer
• Hose set from lid
• Lid from reservoir
12. Close prime valve on sprayer.
