Disconnect tool from power source.
Do not allow the wrenches to contact the columns (A) Fig. 9.
Columns could be damaged, restricting the plunge action.
Avoid possible damage to collet. Never tighten collet without a
bit.
If you remove the springs from the posts (E) Fig. 11 to use
the plunge base in a router table, remove the post plugs
carefully. They are spring-loaded and should be removed
only when the base housing is in the up position (Fig. 8B).
VACUUM HOSE
A standard 1" vacuum hose (A) Fig.
8A can be attached to the dust port
(B) Fig. 8A to connect the tool to a
vacuum cleaner or dust collection
system.
