The air impact wrench is a tool driven by normal
compressed air. There w
ill be a risk of explosion if other
high-
pressure gases like oxygen, acetylene, and propane
are used for the tool.
●Choose the appropriate air hose.
Use oil- and abrasion-resistant air hoses
for the required air
pressure and of the recommended inner di
ameter. Avoid
using deteriorated or excessively long hoses.
●Prevent air leakage.
Make sure that air plugs be firmly attached to the air hose. If
the air hose comes off due to loose connection, it will
bounce around by the force of compressed air and ma
y
cause personal injuries or property damages.

Preparations before use
●Check the air pressure
The specified air pressure for this air tool is 0.6 MPa. If the input air
pressure surpasses this specified level, it will cause damage on the unit or
individual parts.
●Remove the drain
When moisture or impurities like rust in the pipe get into the mechanism, it
may cause malfunction. Remove accumulated drain in the compressor
before use. To secure dry air supply, install an air filter in order to prevent
moisture and any impurities.
●Use an appropriate air hoses
Please refer to Specifications for choosing an air hose of the appropriate
size for the applied air supply. If the internal diameter of the air hose is too
small, sufficient power may not be obtained as air pressure cannot
increase efficiently. It also happens when the hose is too long.
●Install the plug
・GT-CD60-34
Use a spanner of No.17 to hold Air Inlet Bushing
and fasten the plug.
・GT-CD60-34L
Use a spanner of No.19 to hold Air Inlet Bushing
and fasten the plug.
