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.
