HOW TO REPLACE THE BLADE (Continued)
NOTE: Saw teeth point toward the right of the saw when
held in normal operating position. The direction of rotation
is marked on the saw blade. An arrow on the bottom of
the front base assembly also indicates direction of
rotation.
See Figure 24.
16. Tighten blade screw securely. NOTE: Turn blade
screw clockwise to tighten.
17. Replace rear base assembly. Position adjustment rod in
its proper place as shown in figure 25.
18. Secure rear base assembly in place with the two springs.
Hook one end of each spring in notch on each side of
base assembly. Using needle nose pliers, stretch each
spring and hook it over tabs on bearing plate.
19. Reassemble front base assembly.
20. Replace screws and tighten securely with a screwdriver.
21. Replace dust bag.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
MAINTENANCE
When electric tools are used on fiberglass it has been
found that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and grindings are
highly abrasive to bearings, brushes, commutator, etc.
Consequently it is not recommended that this tool be used
for extended work on any fiberglass material. During any
use on fiberglass it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. come in contact
with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.
