Foreword
Sumake is a manufacturer and exporter of air tools since established. We have devote all our effort in
improving quality and tools life. As well as the noise and vibration of tools. Bring all of your working efficiency,
profits and en oy using the tool is our principle.
Features
This tool is designed to meet an extremely wide range of materials which need hole drilling by means of
proper drill bit.
Operator's instruction
Main Applications
This tool is perfect for drilling hole on iron, steel, cast iron, aluminium, nonferrous metal, wood, synthetic
resin etc.
Cautions for Use
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)
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 and the tool. Use 3 HP or larger compressor for each sander.
Air hose
Clean the hose with a blast of compressed air before connecting the hose to air tool. This will prevent
both moisture and dust within the hose from entering the tool and causing possible rust or malfunction. To
compensate for unusually long hose (over 25 ft), the line pressure should be increased accordingly.

Maintenance
Lubrication
Before connecting the hose, apply 4 or 5 drops of #60 spindle oil at the air inlet. Use of a thicker oil can
lead to reduced performance or malfunction. If a thicker oil is used by accident, wash it away immediately.
Also, every 3 or 4 hours of operation, oiling is necessary.
