Operation
1. Pull the trigger switch after applying the tip of the bit to crushing position. In some cases, it's
necessary to punch the tip of the bit against the crushing position forcibly in order to begin the
striking stroke. This is not due to malfunction of the power tool. It means that the safe guard
mechanism against no-load striking is working.
2. Operate this demolition hammer by utilizing its own weight. The performance will not be better
if it is pressed or thrust forcibly against the work surface. Hold with a force just sufficient to
counteract the reaction.
Note:
Sometimes the power tool does not begin the striking the stroke even the motor keep running,
because oil inside become thick. If the power tool is used at a low temperature, or it is used after
a long idle time, this demolition hammer should be kept running for above 5 minutes to warm up.
