Regular maintenance keeps spray foam equipment ready for demanding projects and application schedules. However, daily maintenance is not always enough to keep them in good condition. Use this annual maintenance checklist for spray foam equipment to catch wear that routine daily inspections may miss. A yearly maintenance service also lets you review the proportioner, transfer pumps, and supporting rig components more closely. Always follow the service intervals and procedures in the manual for your specific equipment.
Start With the Proportioner
Before starting your yearly inspection of the proportioner, shut down the system according to the manufacturer’s instructions. Relieve pressure before opening or servicing any fluid components. Graco recommends changing hydraulic oil and filters annually on hydraulic Reactor systems. Electric and pneumatic models have different requirements, so always follow the schedule for your specific machine instead of using hydraulic procedures for every proportioner.
Inspect the machine for leaks or visible wear. Use service records from the previous year to identify parts that required repeated attention.
Inspect the Heated Hoses
Since crews move heated hoses across job sites so often, inspect them thoroughly each year to catch damage that might go unnoticed during daily use. Check the hose covering for worn insulation or exposed wiring, and pay close attention to both hose and electrical connections.
Graco also recommends checking heated hoses for leaks at the connections and for damaged electrical connectors during routine maintenance. Repair worn insulation or damaged hose sections as soon as you notice them! Don’t let these issues carry over into another season.
Service the Transfer Pumps
Transfer pumps move the chemical components from their containers to the proportioner. Seals and motor components can wear over time with regular use. Replace the seals in the transfer pump and motor as needed during your annual service. Inspect the pumps for leaks and make sure they operate smoothly before you return the rig to regular production.
Give the Spray Gun a Detailed Inspection
During annual service, go beyond a quick cleaning for the spray gun. Remove any built-up material according to the manufacturer’s instructions and check all components that affect material flow.
Check inlet filters and other wear components for contamination or damage. For Graco Fusion guns, routine maintenance may also require you to check valves, side seals, and the grease system depending on the model and its condition.
Keep Maintenance Consistent Throughout the Year
Treat this annual maintenance checklist for spray foam equipment as an addition, not a replacement, for your daily or monthly care routine. Keep up with regular checks on items like pump seals and spray gun components throughout the year. When you stay on top of those smaller tasks, your annual inspection becomes a deeper review rather than a catch-up session.
