Needle Scaler SN 16 PG
Operation & Maintenance Guide
AIR SUPPLY:
The Scalers work best at 6.2 bar(90psi) air pressure. The air should be clean, dry and lubricated. Install a FRL unit as close as
operation will permit.
CAUTION:
Assemble Nipple and reducer in the Housing (12) (supplied separately)
REPLACING NEEDLES:
Always turn off the air supply and disconnect the air supply hose. Remove the safety band (8) from the groove. Loosen the stop
ring (6) and remove. Take out the needle supporter (2) by pulling out the needles (1) Topple down needle supporter (2) and
extract the needles (1) -29nos. Whenever the needles are damaged during operation, they must be replaced. After replacing
needles, assemble in the reverse manner of disassembly
MAINTENANCE:
To disassemble SN16PG Needle Scaler, disconnect air supply hose. Remove the safety band (8) from the groove. Loosen the
stop ring (6) and remove. Take out the needle supporter (2) by pulling out the needles (1) Topple down needle supporter (2) and
extract the needles (1) -29 nos. Slide out throttle anvil (3) unscrew rear bolt (12), remove rear washer (11). Topple down housing
(9) so that piston (4) will come out. Pull out cylinder (5) from front, remove ‘O’ Ring (10) To dismantle throttle valve assembly-
unscrew valve cap (13), remove valve packing (14). Pull out throttle valve assembly along with ‘O’ Ring(18) and spring (19). If
throttle lever (16) is to be removed,punch out lever pin(17) and remove lever(16).
Examine all components for wear after washing with light diesel oil or suitable solvent. Replace any worn or damaged parts.
Coat parts with recommended light oil and re-assemble carefully in the reverse sequence.
RECOMMENDED LUBRICANTS:
LUBRICATION REQUIREMENTS:
Always install a line lubricator on the air line as close to the tool as possible. A Filter Regulator Lubricator unit (FRL) is strongly
recommended. Keep the lubricator bowl topped up with recommended grade of oil and check that the oil is reaching the tool.
Running the tool without lubrication is likely to cause damage to the components causing premature replacement.
DAILY BEFORE OPERATION:
Disconnect air hose from the tool and pour in 1 to 2 ounce of recommended oil to the air line port of the tool. Then re-connect
and idle run the tool for a few seconds so that the oil should reach every part in the tool
OPERATION:
This tool is for scaling work pieces using needles. The quick reciprocating needles of the needle scaler adjust automatically to the
surface contour during cleaning. Slight depression of the needles against the work surface is sufficient for work performance. An
upright tool position is the best. The tool will clean uneven surfaces efficiently and get into grooves, corners and gaps, clean out
side and inside surfaces and clean spaces in access able or too confined for other types of tools.
