BASIC GUIDE BAR MAINTENANCE TASKS
BAR CLEANING Clean bar channel (1), oil hole (2), and grease hole (3), daily.
CHAIN TENSION Inspect before use and after every hour of use.
CHAIN AND BAR OIL Inspect before use and after every hour of use. For gas saws, add oil when you refuel. For electric saws, check intermittently.
CHECK FOR DAMAGE Inspect bar for damage and component wear daily and before each use. Replace as needed.
BAR NOSE GREASE Turn nose sprocket while pumping grease until whole sprocket has new grease. Do not push dirt into hole. Clean grease hole before adding new grease.
WEAR EQUALIZATION Turn your guide bar over weekly to equalize bar wear.
FILE BAR EDGE File bar edge to 90° with a flat file weekly.
BAR TIP CLEARANCE On sprocket nose bars, check for clearance around the bar tip between top of rails and the bottom of cutters or tie straps weekly. Replace nose sprockets before cutters or tie straps contact the bar rails.
CHAIN LEAN With chain on the bar, hold a straightedge against the bar body and against a cutter side plate. A good groove will hold the chain straight, leaving a small gap between the straight edge and bar body. A worn groove will let the chain lean until straightedge is flush with bar body. Replace bar if groove is worn. Check weekly.
