Inspect brush wear monthly in continuous operations or every 500 operating hours. Replace brushes at approximately 50% original bristle length; most brushes include an adjustment to compensate for up to 1/2" wear before requiring replacement. Rotate brush position periodically to distribute wear evenly and extend service life. Monitor for bristle degradation in high-temperature or abrasive environments requiring stainless steel brush assemblies.

Monitor reservoir oil level and refill before complete depletion to prevent air introduction that disrupts consistent flow. Inspect oil condition during refills—contamination indicates inadequate filtering or environmental ingress requiring system evaluation. Clean the acrylic reservoir during annual maintenance or when visible contamination accumulates. Verify self-closing filler cap seals properly to prevent dust and moisture ingress.

Verify 120V AC solenoid activation during conveyor startup. Listen for an audible click and confirm flow through the sight feed chamber. Check friction locks on the needle valves haven't drifted from vibration. Inspect the sight feed valve for flow visibility and blockage; contamination in the sight chamber indicates upstream filtration issues. Test solenoid coil resistance if activation fails (typical resistance 800–1200 ohms for 120V AC solenoids).

☐ ANSI chain designation (e.g., C2060H, C2062H, C2080H)

☐ Chain pitch and roller diameter

☐ Operating speed (RPM at drive sprocket or FPM linear velocity)

☐ Duty cycle (continuous, intermittent with hours per day)

☐ Single or multiple chain configuration

☐ Chain width and center distances (for multi-feed requirements)

☐ Electrical specifications: Confirm 120V AC 60 Hz available at lubrication point

☐ Motor control architecture (contactor, VFD, soft start)—determines wiring approach

☐ Mounting clearance constraints and preferred mounting method (pipe mount, remote thread mount)

☐ Ambient temperature range (minimum/maximum) for reservoir material selection

☐ Outdoor exposure or indoor installation

☐ Dust, moisture, or chemical exposure affecting material specifications

☐ Current lubrication method (if retrofit) and known issues (wear patterns, chain elongation rate, noise levels)
