INSTRUCTIONS AND PARTS LIST FOR
SC41011AS PNEUMATIC SCALERS
INTENDED USE
The intended use of this tool is for cleaning, paint stripping, and chiseling on metal surfaces. Do not use this tool for
any other purpose.
AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at 90 psig (6.2 bar). The use of an in-line
filter and pressure regulator will insure maximum output and tool life. Before connecting the tool, blow out the air line to
remove water and dirt which may have accumulated.
LUBRICATION
An airline lubricator, set to deliver one drop per minute, is recommended. If a lubricator is not used, add
.04 oz (1.2 cc) of Sioux No. 288 air motor oil into the inlet daily.
HOSE AND HOSE CONNECTIONS
The supply hose I.D. should not be less than 5/16”(8mm). Do not use coupling or fitting with a smaller I.D. than the
supply hose. When using quick couplers, install a leader hose between the tool and the quick coupler.
GENERAL OPERATION
Operation
Scaler tools with a solid back head do not have on/off valve control integral with the tool. Trigger control is provided
with add on components. Be sure the needles or chisel are against the work piece before depressing the throttle.
Release the throttle to stop the tool.
The scalers are convertible to be used as either a chisel scaler or needle scaler. The needle housing is removed or
installed by pushing the needle housing onto the front of the tool to interlock on the tab extending out the side of the
tool.
The chisels or needle scaler driver are installed or removed by pulling up on the tab extending from the side of the tool
to release the chisel.
Never operate the scaler without a chisel because internal damage can occur to the tool.
Always unhook tool from the air supply before changing chisels.
IF THE TOOL LOSES POWER, CHECK THE FOLLOWING:
• Air pressure
Ensure that there is adequate supply of clean, dry air at 90 psig (6.2 bar).
• Chisels and needles
Check for worn and broken chisels or needles.
• Hose size
Ensure that the hoses, couplers, and fittings meet the criteria in “HOSE AND HOSE CONNECTIONS”.
• Sluggish or erratic operation
Flush tool out with a small amount of petroleum solvent and operate for a few seconds, then re-lubricate the tool
using air motor oil. If the tool still does not perform correctly it will need to be disassembled and repaired.
