Insufficient tightening may cause loosening of the nozzle.
1. Do not apply the blow gun to flammable,
explosive or toxic substances such as gas,
fuel gas or refrigerant. Such substances
may exude from inside the blow gun.
1. Install a stop valve on the supply pressure
side of the blow gun to enable emergency shut
off in case of unexpected leakage or damage.
2. When installing a nozzle on the blow gun, wrap
pipe tape around the threads of the nozzle.
3. When installing the nozzle, secure the
nozzle holder of the blow gun by applying a
spanner of 22 mm width across flats to the
two chamfered surfaces of the holder
without applying force to the body. Then,
tighten the nozzle with force within the
below torque range. As a guideline, it is
equivalent to 2 to 3 additional turns with a
tool after manual tightening.
1. Check the specifications.
The products in this catalog are designed to be used in
compressed air systems only. If the products are used in an
environment where pressure or temperature is out of the specified
range, damage and/or malfunction may result. Do not use under
such conditions.

Warning
Warning
1. Check the model, type and size before
installation.
Also, confirm that there is no scratches, gouges or cracks on the
product.
2. Before piping
Before piping, it should be thoroughly blown out with air (flushing)
or washed to remove chips, cutting oil and other debris from
inside the pipe.

3. Wrapping of pipe tape
When screwing together pipes and fittings, etc., be certain that
chips from the pipe threads and sealing material do not get inside
the blow gun. Also, when the pipe tape is used, leave 1.5 to 2
thread ridges exposed at the end of the threads.
Piping
Caution
4. When tightening the threads, secure the
nozzle holder of the blow gun by applying a
spanner of 22 mm width across flats to the
two chamfered surfaces of the holder
without applying force to the body. Then,
tighten the nozzle with torque specified in
the below table. As a guideline, it is
equivalent to 2 to 3 additional turns with a
tool after manual tightening.
Be careful that tightening with torque beyond the ranges in the
below table may cause damage to the body.
5. Allow extra length when connecting a tube
to accommodate changes in tube length due
to pressure.
6. Confirm that no twisting, turning or tensile
force or moment load is applied to the port
or tube. This may cause fittings to fracture
or tubes to be crushed, burst or come loose.
7. Do not abrade, entangle or scratch the tube.
This may cause the tube to be crushed,
burst or come loose.
1. Use clean air.
Do not use compressed air which includes chemicals, synthetic
oils containing organic solvents, salt or corrosive gases, etc., as it
can cause damage or malfunction.
