Operation Manual
Check the following items prior to operation.
Working Environment
Make sure that the work site is in order prior to polishing operations.
Air supply Quality
Select and install a compressor with sufficient capacity for the recommended air
consumption. Use of compressed air with water and oil may cause rusting and
other problems. Before operating the compressor, drain out the water and oil
completely through the drain port provided at the bottom of the compressor tank.
The Operating Air Pressure
This sander is designed for operation in the optimum air pressure at 90 PSI/6 BARS

(Max. air pressure at 8.0 kgf/cm²). Excessive air pressure levels can cause the
sander to run at excessively high r.p.m. and may cause harm to the operators. Only
operating this sander within the specified air pressure ranges.
The Air Regulator Function
Grip the body while press the lever. Then switch the air regulator to turn the
tool“on”. For faster r.p.m, turn the air regulator valve for air flow control from zero
to max.
Conncetion Of The Air Hose From The Compressor To The Tool
Check the air hose conection plug for small stone particles and dust. Foreign
Object damage (FOD) can be caused by these small stone particles if they get into
the tool.
