A light, spot lubrication of the axles where they pass through the wheel/cam should be done on a regular basis (1,500-2,000 shots). In adverse hunting conditions where dirt, dust, and moisture are encountered, lubrication may be done on a daily basis. Hoyt recommends that you use a silicone or Teflon based lubrication or any other quality grease available at your local Hoyt Pro Shop. It is not recommended that you use "penetrating oils" such as WD-40, EZ #7, Fast Break, etc. Note: Cam & 1/2 System bows feature sealed stainless steel ball bearings which do not require lubrication.
Hoyt recommends applying a light coat of bowstring wax to your bow's strings and cables on a regular basis. Hoyt suggests once every two weeks during peak use. Use a high quality bowstring wax available at your local Hoyt Pro Shop.
Hoyt recommends that a bow's strings and cables should be changed when wear is evident or every two years under normal use conditions.
