HAMMERHOOK

Your tool is equipped with a convenient hook for hanging your tool. To use, simply open hook until it snaps into the open position (Fig. 7).

When using the HAMMERHOOK™ always be aware that the accessory is exposed. Always hang the tool in an area where yourself and bystanards can not accidently make contact with the accessory.

!WARNING To reduce the risk of injury, use care in

selecting the location for hanging the tool.

Select a suitably sized and shaped object that will provide adequate hanging stability. An unstable hanging surface could result in the tool unexpectedly falling.

Insure that the tool is hung out of the way of walkways and working areas with bystanders. The tool could be bumped or a bystander could become entangled in the power supply cord causing the tool to unexpectedly fall.

!WARNING To reduce the risk of injury, Do not use the

hanging hook if it appears damaged or deformed. This could result in unstable hanging and the tool unexpectedly falling.
