Perform  regular inspections fo r
function and accuracy.

Periodical  inspections  are essential to
insure the torque wrench is in optimal
condition thus preventing injury.

Loading direction.

The loading  direction  must be a right
angles to the torque wrench (tolerance:

±

15

°

) (Fig.4). This tolerance applies  to

both horizontal and vertical deviation. 

使用後は、ゴミ・ホコリ・ドロ・油・水
分等の汚れを取り除いて保管する。

汚れがついたまま保管すると、作動不良、
精度不良の原因となります。

13

Remove any dirt such as dust, mud,
oil and water, etc. after each use and
before storing torque wrench. 

長期間使用しないときは、最低目盛りに
セットし、防 錆 油 を 塗 布し、乾 燥した 場
所に保管する。

保管方法が悪いと、精度劣化や耐久性の
低下が早まります。

14

When storing the torque wrench for a
long time, apply rustproof oil, and
keep in a dry place. 

If improperly stored, the accuracy  and
durability will decrease rapidly.
Store the wrench with torque graduation
set to the lowest setting.
