MAINTENANCE
GUIDE BARS
• The guide bar is designed to be used on both sides. If the cut is consistently leading to one side, turn
the guide bar over to expose a new set of guide rails.
• A table mounted belt or disc sander can be used to square the rails of a worn guide bar. A badly worn
guide bar can quickly damage an expensive diamond chain. If the diamond chain is touching the
bottom of the guide bar groove, replace the guide bar.
• Check the guide bar for straightness. Minor adjustments can be made by bending the guide bar
slightly.
• Proper diamond chain tension will extend guide bar life. See page 9.
• Under some circumstances, especially low water pressure, the sprocket nose can wear out before the
guide bar body. Sprocket nose replacement kits may be purchased from an Authorized Dealer
(part #70249).
• Spray the diamond chain and guide bar with lightweight oil for storage.
• Store guide bar with the sprocket nose up.
• Periodically clean the water ports inside the groove of the guide bar using a small diameter piece of
wire.
• The guide bar is solely a guide track for the diamond chain. Never use the guide bar to lift, twist or pry
concrete material.
