Maintenance and Lubrication

• As with most mechanical devices, Restrictor Stays require periodic maintenance and lubrication. The restrictor in general and particularly the pivots, sliding shoe and track must be kept free from dirt, debris and any obstructions at all times.
• At Time of Installation - Lubricate all pivot points with light machine oil and wipe away excess, one drop per pivot is sufficient. We suggest one of the following lubricants or equivalent:
  • General light engineering oil with corrosion inhibitors such as Castrol Everyman or 3 in 1 oil (available in aerosol can for convenience).

Note: Solvent based aerosol sprays e.g. WD40 are not suitable for this application.

• Every Five Years - Carry out the following checks every five years:
  • Clean any dirt or debris from the hinge and clear any obstructions from the pivots, sliding shoe and track.
  • Apply lubrication as instructed
  • Check the tightness and security of all fixing screws and rivets.
