MAINTENANCE
DEPTH GAUGE CLEARANCE
See Figure 29 - 31.

The depth gauge should be maintained at a
clearance of .025 in. Use a depth gauge tool
for checking the depth gauge clearances.

Every time the chain is filed, check the depth
gauge clearance.
Use a flat file and a depth gauge jointer to lower
all gauges uniformly. Depth gauge jointers are
available in .020 in. to .035 in. Use a .025 in. depth
gauge jointer. After lowering each depth gauge,
restore original shape by rounding the front. Be
careful not to damage adjoining drive links with
the edge of the file.
Depth gauges must be adjusted with the flat file in
the same direction the adjoining cutter was filed
with the round file. Use care not to contact cutter
face with flat file when adjusting depth gauges.
MAINTAINING THE GUIDE BAR
See Figure 32.
CAUTION:
Make sure the chain has stopped and the bat-
tery pack has been removed 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 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
MAINTAINING THE SAFE-T-TIP™
NOSE GUARD
See Figures 33 - 34.
WARNING:
This saw comes without the Safe-T-Tip antikick-
back device installed. Install the Safe-T-Tip prior
to using the saw and check the tightness of the
mounting screw each time the saw is used.
Use the following instructions to tighten the mounting
screw of the nose guard. These are specially hard-
ened screws. If you cannot install the screw tightly,
replace both the screw and the SAFE-T-TIP™ before
further operation.
NOTE:
Do not replace the screw with an ordinary
screw. Use only identical replacement parts from the
manufacturer when replacing parts.
In addition to preventing chain contact with solid
objects at the nose of the bar, the SAFE-T-TIP™ also
