DEPTH GAUGE CLEARANCE
See Figures 43 - 44.
 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 adjust-
ing depth gauges.
MAINTAINING THE GUIDE BAR
See Figure 45.
CAUTION:
Remove the battery pack from the chainsaw and make
sure the chain has stopped before you do any work on
the saw. Failure to do so may result in accidental starting
and possible serious 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.
Chain specifications: 3/8 in. pitch, low profile, .050 in. chain gauge, 7-tooth drive sprocket.
Length of Bar
20 in.
MAINTENANCE

BAR AND CHAIN COMBINATIONS

Guide Bar Part Number
682773001
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
TRANSPORTING AND STORING
See Figure 46.
WARNING:
Always remove the battery pack before transporting or
storing chainsaw. Place battery pack indoors in a dry,
secure location out of the reach of children when storing.
Failure to follow these instructions may lead to accidental
starting or unauthorized use and result in serious personal
injury.
 Do not store or transport the chainsaw when it is running.
The chainsaw should always be idle before storing or
transporting.
 Always place the guide bar scabbard on the bar and chain
before storing or transporting the chainsaw. Use caution
to avoid the sharp teeth of the chain.
 Clean the chainsaw thoroughly before storing. Store the
chainsaw indoors, in a dry place that is locked and/or
inaccessible to children.
 Keep away from corrosive agents such as garden chemi-
cals and de-icing salts.
