PREPARATIONS BEFORE USE
Caution
● Please ask your original dealer or authorized distributor of our company for installation work of a high
pressure hose to a regulator.
● When you tighten high pressure hose couplings with a spanner, please keep the tightening torque of 9.8N・
m (100kgf・cm or 1/36 rotation from the start of tightening.). Otherwise it may cause to damage the
threads portion.
● Please do not attach the hose guard made in other company.
Warning
● Please attach a hose in the state that the first stage of a regulator is not connected
to a tank. If the first stage is pressurized during work, a plug in the port flies and
it is dangerous.
● Please use the regulator with the coupling thread size of 7/16-20UNF of an “H.P.” port.
Otherwise, not only it causes the damage of equipment, but also a hose comes off and it
may cause an accident resulting in injury or death.
● Please be sure there is O-ring at the end of the threads portion of a high pressure hose. When there is
no O-ring, it causes the air leakage.
Check of the high pressure hose. Operation check.
Check of“0”display on the pressure gauge.
Setting to a tank.
Check of the air leakage.
Warning
● If you find an abnormality in your gauge by the following various checks, you must not use it.
● When there is an abnormality, contact your original dealer or authorized distributor of our company. Use
of the gauge which is not normal may cause an accident resulting in injury or death.
● Because of its structure, there is a possibility of causing a sand jam, so please be sure to perform
operation check. When foreign substances, such as sand, are jammed, it does not show a standard of tank
pressure.
Check whether the hose is damaged or has broken. Please push the end of a slide cover with a thumb or a palm, and check
that a slide cover moves smoothly.
Check if the indication button of the pressure gauge indicates“0”.
According to the operating manuals for a regulator and a tank for
scuba diving, install a regulator first stage to a tank valve, and
open the tank valve.
Check whether air is leaked at the connecting portion of a regulator
first stage, a gauge and a hose.
Warning
● When you open a tank valve, keep away the slide cover
of a gauge from a person and your face, and open the
valve slowly. When it goes off accidentally by a certain
reason, it may cause an accident resulting in injury or
death.
Warning
● When the air leakage is found in check, please stop use
and remove a regulator first stage from a tank.

(It is normal that it does not move when the residual pressure is
zero.)
The scale which the indication button pointed out is a residual
pressure in general.
READING AND USAGE
6
Warning
● Please perform operation check before start of pressure
gauge reading. (Page 5) Use of the gauge which is not
normal may cause an accident resulting in injury or
death.
● Before reading a scale, please push a slide cover with
a finger and confirm if it moves. When not moving, even
if there are indications, residual pressure has the
possibility of zero because of sand jam etc. If this
confirmation is not carried out, it may become the
accident of drowning caused by the running out of air.
Caution
● At the end of a diving, please be sure to leave 50bars
or more of air in a tank. If water goes into a tank,
there is a possibility that water may go into the inside
of pressure gauge at the next time of use.
CARE AFTER USE
【Note】
○ The residual pressure can be known by the positional relationship
of the indication button and the scale button.
【Note】
○ The residual pressure can be known by the stroke when a slide cover
is pushed. Standard is 100bar par 1 cm.
Wash.
Soak the whole equipment to fresh
water for about 15 minutes in the
state of being set with the
regulator. Then, rinse the whole
in water to wash away foreign
objects such as the salt and
sand.
Caution
● Equipment may be damaged if soaked in hot water
of 50℃ or more.
● Please do not wash a pressure gauge with water in
the state that it is not connected with a
regulator. Water comes in a hose and a gauge, and
may cause the trouble.
● Please be sure to put the dust cap of the
regulator first stage firmly. Otherwise water
comes in the hose and the gauge, and it causes
failure.
■Avoid direct rays, dry a pressure gauge fully in the shade with the
dry, cool and sufficient ventilation.
Drying-Out
■ Wash and dry a pressure gauge fully.
■ Avoid direct rays, and store a pressure gauge in the state being
set with a regulator in the place with the dry, cool and sufficient
ventilation.
The Way of Storage
Caution
● Please keep the hose in a natural form. Forced
bending causes kinking of a hose and shorten a hose
life remarkably.
● Please do not leave a pressure
gauge in the state of high
temperature, such as in a car or
on a beach.

【Note】
● Some parts carry out natural deterioration. Exchange of such parts
is also performed by periodic check.
Warning
● Regardless whether or not you use it, a pressure
gauge may not function normally when you ignore a
periodic inspection.
● Also when it passes with unused condition more
than one year, please use it after taking out to
a periodic inspection.
■Regardless of frequency and the number of times in use, please ask
your original dealer or authorized distributor of our company for a
periodic inspection per once in a year. (Pay Service)
