SELECTING THE ABRASIVE
The best finishes can be achieved by selecting the proper type of abrasive.
coarser grit abrasives will remove the most material while finer grit abrasives
will produce the best finishes.
Achieve best results by selecting the proper size and type of abrasives.
Start the work with an abrasive grit just coarse enough to remove high spots
and excessive roughness. Follow with a second sanding using a grit one or
two grades finer. Continue using successively finer grits until the desired
finish is obtained.
ATTACHING PAD OR PROFILE MOUNTING PLATE
All of the accessory pads and profile mounting plates are attached to the tool
in the same way. Each pad or mounting plate has two posts (A) Fig. 7 used
to attach it to the Profile Sander.
One pad post fits into a pocket (B) Fig. 7 in the tool, and the other post is
locked into place by a tab (C) Fig. 7. The mounting post area (of all the pads
and mounting plates) is symmetrical. The pad (or mounting plate) can be
attached to the Profile Sander with either end forward, which allows the use
of both pointed ends of each sheet of pad abrasive, and permits the profile
holders to be mounted in the best position for each particular application.
To attach a pad or mounting plate to the Profile Sander:
1. DISCONNECT TOOL FROM POWER SOURCE.
2. Position one of the pad (or mounting plate) posts (A) Fig. 7 into the
pocket (B) Fig. 7 of the Profile Sander (Fig. 8).
3. Depress latch button (D) Fig. 9, seat pad to sander, and release latch
button to secure the pad in place (Fig. 10).
4. To remove pad (or mounting plate), depress latch button (D) Fig. 9, and
pull pad away from sander.
