MAINTENANCE
Fig. 46
MAINTAINING THE GUIDE BAR
See Figure 45.
CAUTION:
Make sure the chain has stopped and the bat-
tery pack has been removed 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 socket at the end of the guide bar
using a grease syringe in the lubricating 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
Chain specifications: 3/8 in. pitch, low profile narrow kerf, .043 in. chain gauge, 5-tooth drive sprocket.


Do not store or transport the chain saw when
it is running. The chain saw should always be
idle before storing or transporting.

Always place the guide bar scabbard on the
bar and chain before storing or transporting the
chain saw. Use caution to avoid the sharp teeth
of the chain.

Clean the chain saw thoroughly before storing.
Store the chain saw indoors, in a dry place that
is locked and/or inaccessible to children.

Keep away from corrosive agents such as gar-
den chemicals and de-icing salts.
