10. REPAIR GUIDE

WARNING: Without fail, remove the Type EB 14B or EB 1430H Battery from the main body before starting
repair or maintenance work. Because the tool is cordless, if the battery is left in and the
switch is activated inadvertently, the motor will start rotating unexpectedly, which could
cause serious injury.
