Operator‘s instruction
1. Main Applications
This tool is perfect for scraping out plastic or
rubber protuberance from a mineral/metal
material surface to make the surface smoother.
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)
57
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.

daily
A portion of the water content, however, is
condensed in the piping, and can enter the tool
mechanism, and may causetrouble. So, install
an air filter and on oiler between the
compressor and the tool. Use a 3 HP or larger
compressor for each sander.
2-3 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.
Drainage
2-4 The approved eye protector, ear-muff,
mouth-muffle, and gloves should be worn
when operate this tool.
2-5 The working place shall be ventilative.
2-6 Release the on-off device in the case of
energy supply failure.
2.7 Always disconnect tool from the hose
before changing blade or making any
adjustment.

4. Maintenance
4-1 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,
wipe it away immediately. Also, every 3 or 4
hours of operation, oiling is necessary.
4-2 Storage
Avoid storing the tool in a location subject to
high humidity. If the tool is left as it is used , the
residual moisture inside the tool can cause rust.
Before storing and after operation, oil the tool at
the air inlet with spindle oil and run it for a short
time.
4-3 Disposal
If the tool is too seriously damaged to be used
anymore, drop it in a resource recycling can.

General preparation and connection:
1. Before connecting the air hose, apply 4 to 5 drops of SAE#10-20 spindle oil at the air inlet. Also, every 3 to 4 hours of operation, oiling is
necessary. Twist Teflon thread tape to ensure a proper seal air inlet. Then tighten the air coupler into air tool.
2. The supplied compressed air must be clean and dry, with the appropriate oil mist. Use an air treatment unit; filter, regulator and
lubricator.
3. Please refer Fig.1 illustration shows the correct mode of connection to the air supply system which will increase the efficiency and useful
life of the tool.
4. The quick connect coupling and hose must have sufficient air flow capacity. We recommend an air hose with a diameter of 10mm (3/8”).
5. To ensure a good performance. The operation pressure at the compressed air inlet should not exceed 6.3bar (90psi) (unless indicated
otherwise). Higher operating pressures may cause damaged or excessive wear. Operating pressures below 5.3bar may cause pressure
or power loss.
Risk of injury
