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