Operator‘s instruction
1. Main Applications
This tool is perfect for drilling hole on iron, steel,
cast iron, aluminum, nonferrous metal, wood,
synthetic resin etc.
2. Cautions for Use
2-1 Air pressure
Maximum performance is displayed at the proper
sanding speed, obtainable at a gauge pressure of 6.2
bar. Range-wise, this is an air pressure from 5 to 7
bar (70 to 100 psi)

2-2 Air line
Use a 3/8“ air hose between the compressor and the
tool . Compressed air is cooled and its water
content separated, as soon as the air leaves the
compressor.

A portion of the water content, however, is
condensed in the piping, and can enter the tool
mechanism, and may cause trouble. So, install an
air filter and on oiler between the compressor an
the tool. Use a 3 HP or larger compressor for each
sander.
2-3 Air hose
Clean the hose with a blast of compressed ai
efore connecting the hose to air tool. This will
revent both moisture and dust within the hose
from entering the tool and causing possible rust o
malfunction. To compensate for unusually long
hose (over 25 ft), the line pressure should be
increased accordingly.
Drainage
