Spray System
Maintenance
Chemical substances used in the spray system
may be hazardous and toxic to you, bystanders,
animals, plants, soils or other property.
• Carefully read and follow the chemical
warning labels and Material Safety Data
Sheets (MSDS) for all chemicals used
and protect yourself according to the
chemical manufacturer's recommendations.
For example, use appropriate Personal
Protective Equipment (PPE) including
face and eye protection, gloves, or other
equipment to guard against personal contact
with the chemical.
• Keep in mind that there may be more than
one chemical used and information on each
should be assessed.
• Refuse to operate or work on the sprayer if
this information is not available!
• Before working on a spray system
make sure the system has been triple
rinsed and neutralized according to
the recommendations of the chemical
manufacturer(s).
• Verify there is an adequate supply of clean
water and soap nearby, and immediately
wash off any chemicals that contact you.
Inspecting the Hoses
Service Interval: Every 200 hours—Inspect all hoses
and connections for damage and
proper attachment.
Examine each hose in the spray system for cracks,
leaks or other damage. At the same time, inspect the
connections and fittings for similar damage. Replace any
hoses and fittings if damaged.
Pump Maintenance
Inspecting the Pump
Service Interval: Every 400 hours/Yearly (whichever
comes first)—Inspect the pump
diaphragm and replace if necessary.

Adjusting the Air Pressure in Dampener
The air pressure in the dampener on the pump is set at
15 psi (1 bar) by the manufacturer. The recommended
pressure in the dampener is 1/3 of the spraying pressure.
If using a spray pressure greater than 45 psi (3.1 bar)
adjust the dampener accordingly.
