It's a simple install. The hook is designed to go on either side of the tool, so you can choose which is more comfortable for you.
- Locate the groove on the tool housing on the side where you want the hook.
- Insert the hook into that groove.
- Secure it firmly with the provided screw. Tighten it well.
To remove it later, just loosen the screw and take it out. The hook is meant for temporarily hanging the tool, not for supporting its weight during operation.
Heads up: Always secure the hook with the screw firmly. If not, the hook may come off and cause personal injury.
