Needle Scaler
INSTRUCTION MANUAL
Air Supply Requirements
1. Supply tool with 90 psig (6.2 bar) of clean, dry air. Higher
pressure drastically reduces tool life.
2. Connect tool to air line using pipe, hose, and fitting sizes
shown in the diagram.
Lubrication
1. Use an air line lubricator with SAE #10 oil, adjusted to two (2)
drops per minute. If an air line lubricator cannot be used, add
air motor oil to the inlet once a day.
2. The use of synthetic oils for air line lubrication is not
recommended because of possible damage to seals, o-rings,
hose, rotor blades and polycarbonate oiler/filter bowls.
Operation
For Needle Scaler
1. Push in the front assembly and twist to the open slot, then
pull needle assembly out of housing.
2. Remove worn needles from holder and replace with new
needles, making sure the needle heads fit into the
countersunk holes in needle holder.
3. Slide needles through spring and front nosepiece. Check that
driver is not damaged and placed inside housing correctly.
4. Lubricate entire needle assembly with a light coating of oil.
Reassemble by sliding assembly into the housing, line up
slot, then push in and twist to lock in place.
For Chisel Scaler
1. To insert chisel, press loop on retainer aside, push chisel into
cylinder and release loop.

Caution: Do not operate tool without chisel in cylinder,
or allow the chisel to be driven out of cylinder. Internal
damage will result if piston is allowed to strike cylinder
wall.
Maintenance
1. Disassemble and inspect air motor every three months if the
tool is used every day. Replace damaged or worn parts.
2. High wear parts are underlined in the parts list.
3. Dirt or gum deposits cut tool power. To correct this, flush out
the tool with gum solvent oil or an equal mixture of SAE #10
oil and kerosene. If outside conditions are in order,
disassemble tool, replace worn or damaged parts, clean,
reassemble and relubricate.
