Maintenance of Tool
Lubrication
Closed-type, grease-sealed ball bearings are used throughout.
These bearings have sufficient lubrication packed in them at the
factory to last the life of the bearing.
Gears should be relubricated every 60 to 90 days, depending upon
use. This lubrication should only be attempted by experienced
power tool repairmen like the mechanics at D
service centers. (See "Tools, Electric in yellow pages.) The gear
case should be wiped clean and 3/4 oz. (20 grams) of grease
placed in the gear case.
Cleaning
Blowing dust and grit out of the main housing by means of an air
hose is recommended and may be done as often as dirt is seen
collecting in and around the air vents.
Motor Brushes (Fig. 7)
Be sure tool is unplugged before inspecting brushes. Brushes
should be regularly inspected for wear. To inspect brushes,
unscrew the plastic brush caps (located in the sides of the motor
housing) and the spring and brush assemblies may be removed
from the tool. Keep brushes clean and sliding freely in their
guides. When the brushes wear to the point that the wear line
shown in Fig. 7 is even with the end of the brush holder, the
brush/spring assemblies (both) should be replaced.
Mounting Methods
To improve stability during use, the saw should be firmly mounted
as described below. To enhance the tool's portability, it can be
bolted to a piece of 1/2" or thicker plywood which can be clamped
to a suitable horizontal work surface.
