Compound can be loaded into the Blue Line Flatbox either with the aid of a Loading Pump
and appropriate filler nozzle or by hand.
1. Attach the filler nozzle to pump.
2. Fit the nozzle into the slot on the bottom of the Blue Line Flatbox.
3. Pump the compound in to the Blue Line Flatbox, moving the box from side to side
while pumping to ensure the compound is evenly distributed. Do not overfill.
4. Remove any excess compound from around the slot.

2. Evenly fill the Blue Line Flatbox with compound using a joint knife. Do not overfill.
3. Close the lid.
4. Remove any excess compound.
1. Set the box at a slight angle from the handle and apply the brake so the head
remains stationary.
2. Place the Blue Line Flatbox on the joint and while applying pressure, release the
brake allowing the box and the handle to find is own natural position.
3. Run the Flatbox along the joint applying pressure evenly to ensure a consistent
finish.
4. Reapply the brake toward the end of the joint.
5. Remove the box from the wall in a sweeping motion about 12” from the end of the
joint.
6. Using the same technique, turn around, and coat the remaining 12” of the joint.

General Maintenance
Flatbox Blade
Your Blue Line Flatbox should be cleaned after every use to maximize lifespan and maintain
optimal performance.
Remove any compound from your Blue Line Flatbox with a hose and stiff brush. The Blue
Line Flatbox can be dismantled for a more thorough clean when required.
To maintain smooth unrestricted movement, once a week spray with a silicone spray.
Avoid spraying the rubber seals as this may reduce their lifespan due to perishing.
Regular wear parts should be replaced as needed.
If the Blue Line Flatbox Blade cannot be adjusted to the required height it will need to be
replaced by following these simple steps.

CARE OF YOUR TOOLS
1. Tighten the screws on the blade holder so that the blade is forced out of the blade
holder groove.
2. Remove the blade from the blade holder. If there is resistance, a screwdriver can
be used to gently lever it out.
3. Remove all dry joint compound from under the blade and in and around the blade
holder using a wire brush.
4. Bend the new blade into a slight ‘w’ shape, this keeps the blade secure.
5. Adjust the screws on the blade holder so the blade is the thickness of a fingernail
above the skids. (refer to illustration from 'before use' regarding the width of the
Tapepro Flatbox Blade).
