SmarTraq Door Operator
• Check and adjust as needed:
• Motor V-belt: Mid-way between the pulleys, the belt should deflect 1/2-inch (13mm)
under moderate pressure. The belt should not slip. Replace if cracked or worn.
• Open and close stop rollers: Check for flat spots. Rotate or replace as needed.
• Chain tension: Adjust tension roller to remove slack if needed.
• Urethane dampening strips: Check urethane strips around chain pulley and sprocket.
Replace if broken. (These strips reduce operator noise.)
• Door linkage bearings: Oil or grease once a year.
• Clutch cable: Check tension. Adjust if undue slack.
• Door bumpers: Check for distortion or cracking. Replace if needed.
• Check that operator and motor mountings are tight and true.
• Clean, but do not lubricate chain. (Excess can drip down onto passengers.)
