Operation
(continued)
To cover vertical wall joints, lock the handle and begin covering the joint from the bottom up to a height
of about 30” (.75 m), sweep off and begin again at the top of the joint. Move down the joint until you
reach the previous stopping point. Then lock the handle and sweep off the surface, neatly joining the
two finished sections.
For door or window openings, always work from the corner, moving toward the opening. Just before
the wheels reach the opening, lock the handle and lift the wheels to keep them from dropping into the
opening, then sweep away from the wall.
Before starting the finish coat, lightly sand the dried topping coat to remove any small crumbs. Fill the
10” or 12” (250-300 mm) box and set the dial to #3 for a medium crown. Apply a finish coat to all joints.
For butt joints, apply a coat on either side of the center of the joint. After the two side by side coats
have dried, finish them with a 10” or 12” (250-300mm) wide skim coat over the center of the joint.
Reset the crown dial to #5 for a tight crown then cover the flat joints on the ceilings and walls.
The pressure plate on the Power Assist™ Box CANNOT be moved inward unless the wheels are triggered
and the pressure plate “catch” is released. This applies to both running the tool and emptying unused
compound. To refill the Power Assist™ Box pull back on the handle to open the pressure plate to its
open position.
Maintenance
Remove the springs from the mounts on top of the radius plate to open the pressure plate for cleaning.
The wheels must be triggered to re-install the pressure plate into the box after cleaning.
Clean thoroughly with brush and water (or water hose) to remove all joint compound from the tool.
Then, after the tool is clean, lightly oil with Ames® Bazooka® Oil or any light machine oil.
Box Blade Replacement
1. To remove the used blade, place the tip of a screwdriver against one end of the blade and tap the screwdriver with the
palm of your hand.
2. If the blade does not pop out, tighten the screw at one end of the brass blade holder, forcing the end of the blade out.
Back the screw up and again tap the end of the blade.
3. Use one end of the used blade to clean any dried compound from the blade holder slot.
4. Remove both right and left skids, but leave the repair clips in place.
5. Slightly bend the new blade approximately 2 inches from both ends. This will help secure the blade while the tool is in use.
6. Start at one end, pressing the blade all the way into the blade holder, working to the other end. Install new skids. The
“dog ear” on the skids should press against the back side of the new blade and be flush with the blade holder (about the
thickness of a thumbnail lower than the blade edge).
