MAINTAIN PROPER CLEARANCE BETWEEN DOOR AND SURROUNDING FRAME AND THRESHOLD.

RE-ADJUST DOOR CHECK REGULATING VALVES IF REQUIRED FOR MAIN AND FINAL CLOSING SPEEDS. ADJUST BACKCHECK FOR "LIGHT" CUSHIONING ONLY. REFER TO INSTALLATION INSTRUCTIONS. CHECK DOOR CLOSING TENSION. ADJUST AT FLOOR WITH TENSION ADJUSTER IF NEEDED. BE SURE TO CLOSE LOCKING SCREW.

NEVER LUBRICATE THE TRACK IN THE HEADER OR TOP OF DOOR! REFER TO PARTS LIST, BEARINGS REFERENCED E-8, N-30, L 30 AND 32 AND K 25 & 28 ARE 100% GREASE FILLED AT TIME OF ASSEMBLY AND SHOULD NOT REQUIRE RE-LUBING FOR 5 OR MORE YEARS. MOST COST EFFECTIVE APPROACH IS TO WAIT FOR EVIDENCE OF DRYNESS AND THEN RE-LUBE OR REPLACE AS INDICATED.

BE SURE THE GUIDE ROLLERS (REF GE) ARE IN PROPER WORKING ORDER. THEY SHOULD TURN FREELY AND BE MOUNTED SECURELY IN THEIR PROPER LOCATION.
