KTC Tire Air Gauge (AGT231, AGT232)

Thank you for purchasing KTC Tire Air Gauge (AGT231, AGT232).
This measuring instrument is used for adjusting the air pressure of
car tires. Please read the following instructions to ensure safe
and appropriate use.

Cautions in Handling

This gauge is provided with an air coupler (20PM made by Nitto
Kohki Co., Ltd.) as standard equipment.
When replacing the air coupler, fix the adaptor with a box-end
wrench to protect the packing between the grip and prevent tire
blowout.

How to Use

Air Pressure Measurement

Remove the valve cap.
Press the valve with the connector, avoiding air leakage from
between the tire valve and connector. (Note: Do not move the
operation lever.)

Compression / Decompression (Air Pressure Adjustment)

Attach the air hose.
Remove the valve cap.
Press the tire valve, avoiding air leakage from between the
valve and the connector.
Press the operation lever halfway (approx. 5 mm) to
decompress.
Press the operation lever completely (approx. 10 mm) to
compress. Tire air is decompressed by gradually releasing the lever
from the compression position.
Air pressure in the tire is displayed on the gauge with the
release of the operation lever. Adjust the air pressure until it
reaches the standard value. (Note: For the standard air pressure
value of the tire, refer to the label on the driver side door of
the automobile.)
After air pressure adjustment, check with soap water, etc. if
air is leaking or not.

TIRE AIR GAUGEAGT231,AGT232Instruction Manual
Thank you for purchasing KTC Tire Air Gauge (AGT231, AGT232). To use the instrument safely and appropriately, please be sure to read this handling instruction before use. (Please store it with the instrument.)
This is a measuring instrument used for adjustment of air pressure of car tires (measurement, compression, decompression).
Cautions in Handling
This gauge is provided with air coupler (20PM made by Nitto Kohki Co., Ltd.) as a standard equipment. . When replacing air coupler, fix the adaptor with box end wrench to protect the packing between the grip and
the adaptor. Do not use anything other than air from the air compressor. Use clean air. (Remove water from air compressor tank and air filter.) Do not disassemble or scratch the instrument. Do not use near fire, or in place where water or oil may be splashed. It may cause failure. Look at the gauge front ways to read measurement. Do not use gasoline, thinner, etc., for cleaning the gauge to avoid deformation. If dropped or cracked , or depending on the condition of use, check the accuracy of the gauge. Compress within the standard range of air pressure of the tire. Compressing beyond the range
may cause tire blowout.
Application AGT231
Applicable to passenger cars or commercial vans (Max. measurable value: 500 kPa)

How to Use
Air Pressure Measurement
Remove valve cap. (Fig.1) Press the valve with the connector
avoiding air leakage from between tire valve and connector (Fig.2) . (Note) Do not move the operation lever.

Compression / Decompression
(Air Pressure Adjustment)
Attach air hose. (Fig.3) Remove the valve cap. Press the tire valve avoiding air
leakage from between the valve and the connector (Fig.2). Press the operation lever half way (approx. 5 mm) to decompress. (Fig.5) Press the operation lever completely (approx. 10 mm) to compress. Tire air is decompressed by gradually releasing the lever from the compression position. (Fig.5) Air pressure in the tire is displayed on the gauge with release of the operation lever. Adjust the air pressure until it reaches the standard value.

(Note) For the standard air pressure value of the tire, refer to the label on the driver side door of the automobile.
(Note) After air pressure adjustment, check with soap water, etc. if air is leaking or not (Fig. 6).
