Lubricating The Blade - Craftsman 172.79957 Operator's Manual

SHARPENING THE BLADE
1. Allow your hedge trimmer to come to a stop with
the cutter blade and guard positioned as shown
in Figure 8. This will allow clearance for the file
between the cutter teeth and the guard teeth.
2. Disconnect the trimmer from the power supply.
3. Clamp the blade assembly in a vise and file the
exposed cutting surface of each blade tooth with
an 8-inch fine round file, having a 1/4 or 7/32-inch
diameter. Be sure to retain the tooth's original
angle when filing.
4. Remove the hedge trimmer from the vise, restart
it, and stop it so the unsharpened edges of the
blade teeth are exposed.
5. Disconnect the tool and repeat the sharpening
procedure as described above.

LUBRICATING THE BLADE
To lubricate the cutting blade, disconnect the hedge trimmer from the power
supply.
For easier operation and longer blade life, lubricate the hedge trimmer blade
before and after each use. Before lubricating, be sure the unit is OFF and
unplugged from the power supply. Apply light machine oil along the edge of
the top strap (see Figure 8).
,_ CAUTION: Some spray-on lubricants contain solvents and
will cause some types of grease to break down. To prevent
damage to the unit, only use a quality machine oil.
