Maintaining The Guide Bar - Black Max BM3716 Manual Del Operador

MAINTAINING THE GUIDE BAR

See Figure 55.
CAUTION:
Make sure the chain has stopped before you
do any work on the saw to avoid accidental
starting or contact with the moving chain that
may result in injury.
Proper maintenance will maximize the useful life
of the guide bar.
Each day of use:
Clean the bar and check for wear and damage.
Feathering or burring of the bar rails is a normal
process of bar wear, but such faults should be
smoothed with a file as soon as they occur.
Each week of use:
 Reverse the guide bar on the saw to distribute
the wear.
 Lubricate the sprocket at the end of the guide
bar using a grease gun in the sprocket lubrica-
tion hole.
 Turn the guide bar and check that the lubrication
holes and chain groove are free from impurities.
A bar with any of the following faults should be
replaced immediately:
 Wear inside the bar rails that permits the chain
to lay over sideways
 Bent guide bar
 Cracked or broken rails
 Spread rails
MOUNTING THE ANTI-KICKBACK
NOSE GUARD
See Figures 56 - 57.
 Stop the engine and disconnect the spark plug
wire.
 Mount the anti-kickback nose guard on the bar
nose.
 Fit the locking tab in the recessed slot in the
guide bar.
 Tighten the screw with wrench until snug.
 From the snug position, tighten the screw an
additional 3/4 of a turn using a wrench.
