4. Place the needle driver (Fig. 1-5) against the needle holder and align the tab
(Fig. 1-6) with the slot in the needle tube. Push the needle tube onto the main
body (#1) until the tab reaches one of the notches. Rotate the needle tube to lock
the tab into the notch.
OPERATION
PRESSURE DROP
Apply the air consumption and pressure rate numbers to the tool’s air inlet, not the
compressor’s outlet. Calculate the pressure drop for your air supply set-up and
increase the compressor outlet pressure to compensate. Make sure you do not exceed
the maximum pressure for any part of your air supply system.
Installing a pressure gauge at the tool inlet is the best way to measure the air pressure
and adjust the compressor’s output.
TOOL OPERATION
1. Select the amount of force the needles will apply to the workpiece. Each notch
closer to the front reduces the stroke length and force.
2. Grip the tool with both hands. Place one hand on the needle tube (#29) and the
other hand on the main body (#1).
3. Press the lever (#9) to operate. Make sure the needles are not touching any
surface when you turn on the tool.
4. Place the vibrating needles on the work surface at an angle between 60º and
70º. Move the needle scaler around in the area from which you wish to
remove the material.
5. Keep only light pressure on the tool while in use. Do not apply heavy pressure as
it may damage the surface area.
6. Do not hold the needle scaler in any one area of the work surface for more than a
few seconds. Longer intervals could damage the surface.
7. If the needle scaler will not remove the material from the surface after a few short
attempts, do not continue. Use another method to remove the material.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is efficient, easier to control
and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace damaged or worn
components. Only use identical replacement parts when servicing.
