What should I do if the motor fails to start when I press the trigger?

First, check that the battery is secure by making sure the latches on the battery compartment snap into place. If the battery is secure, charge the battery according to the instructions included with your model. If neither resolves the issue, there may be a wiring or electrical contact problem — call 1-888-3KOBALT (1-888-356-2258) for technical service. (Page 17)
