Operation
The needle scaler must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Place needles with spring and needle holder
into needle tube. (See exploded view for
proper orientation.)
2.
Place needle tube over barrel. Push until
retainer lever reaches desired notch, then
twist needle tube to secure retainer lever in
notch.
3.
Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
4.
Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT:
Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
Note: For best results, prepare work surface by
removing any oil, grease, or dirt before using
needle scaler. Clean only 6 to 8 inches of surface
area at one time, and make 2 or 3 passes.
5.
Hold needle scaler firmly with both hands, at
approximately 45 degree angle from work
surface.
6.
Place needles upon work surface and press
throttle lever. Pressure against throttle lever
determines speed of tool. Do not exert
excessive pressure against work surface –
let the tool do the work.
7.
Release throttle lever to stop needle scaler.
Maintenance
Lubrication
The needle scaler should be lubricated
daily
(or
before each use) with air tool oil through the air
inlet. During continual operation, it should be re-
oiled every 1 to 2 hours. This can be done with an
in-line oiler, or manually. If done manually,
proceed as follows:
1.
Disconnect air hose from tool.
2.
Place 4 or 5 drops of air tool oil into air inlet.
NOTE: Air tool oil not provided; it is available
at most major hardware and tool stores. SAE
#10 oil or sewing machine oil may be used
as a substitute. Do not use detergent oil.
3.
Re-connect air. Run needle scaler at low
throttle without load for a few seconds to
distribute the oil throughout tool.
4.
When finished operating needle scaler,
disconnect air hose. Wipe off housing with a
dry cloth. Place 4 or 5 drops of air tool oil into
air inlet; re-connect air and run tool for a few
seconds to distribute the oil. Disconnect air.
Storage
Avoid storing the needle scaler in very humid
locations which promotes rusting of internal
mechanisms. Always oil the tool and disconnect
air hose before storage.
