General Maintenance Instructions

for Straight Sliding, Tangent, Council & Runways 290, 301, 301H, 305, 307


  • Keep track free from obstruction and excessive dirt or water.
  • Where fitted to the outside of the building, it is recommended that a protective canopy is fitted (not by PCH).
  • Lubricate track running surfaces with a suitable, good quality automotive grease every six months.� Increase lubrication frequency�in exposed locations or where doors are constantly being operated.� In very dusty locations greasing is not recommended, and if possible nylon wheeled hangers should be fitted, which eliminates the need for track greasing.


  • All hangers are fitted with sealed lubricated ballbearings or plain bearings, requiring no greasing.
  • If doors 'settle' and door clearance is reduced causing friction, raise the door by the hanger adjustment nuts.


  • Guide roller and guide channel must be kept clear and free of obstructions.
  • Guide roller spindles must be oiled and greased every six months.


  • Inspect all fixing bolts for tightness every six months, including those securing brackets. Tighten if necessary.
  • Lubricate all moving parts and check for wear. If excessively worn, the part should be replaced.
