BASIC GUIDE-BAR MAINTENANCE (CONTINUED)
Turn nose sprocket while
pumping grease until whole
sprocket has new grease.
Do not push dirt into the
hole.

◆◆
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
straightedge and bar body.
A worn groove will let the chain lean until straightedge
is flush with bar body. Replace bar if groove is worn.
On sprocket-nose bars,
check for clearance around the
bar’s tip between the tops of
rails and the bottoms of cutters
or tie straps. Replace nose
sprockets before cutters or tie
straps contact the bar rails.
