secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
CAUTION:
Make sure to hang the tool
securely before releasing your hold. Insufficient
or unbalanced hooking may cause falling off and you
may be injured.

WARNING:
Never use the hanging hole for
unintended purpose, for instance, tethering the
tool at high location. Bearing stress in a heavily
loaded hole may cause damages to the hole, result-
