TELESCOPING GUARD
The telescoping guard (A) Fig. 3, is a safety device
important to your protection. Every time you use the saw, see that
the telescoping guard rotates freely and returns quickly and
completely to its closed position. At least once a month, remove
any accumulated sawdust, pitch, etc., from the area around the hub
(B), of the telescoping guard. DO NOT LUBRICATE THIS AREA. The
hub has a dry film lubricated surface that does not need oiling.
NEVER block or wedge the telescoping guard in the open position.
NEVER use your saw if the telescoping guard is not
in working order. If telescoping guard movement is sluggish or
binding exists, return the saw to your nearest AUTHORIZED
PORTER-CABLE SERVICE STATION or PORTER-CABLE SERVICE
CENTER for repair.
