Maintaining The Guide Bar - Ryobi RY3818 Manuel D'utilisation

MAINTAINING THE GUIDE BAR

See Figure 55.
CAUTION:
Make sure the chain has stopped before you
do any work on the saw.
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 SAFE-T-TIP NOSE
GUARD
See Figures 56 - 57.
 Stop the engine and disconnect the spark plug
wire.
 Mount the SAFE-T-TIP 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.
 Check the security of the SAFE-T-TIP nose
guard and its mounting screw before each use
of the chain saw.
