Prior to operation
1. Power source

specified on the name plate of the hammer.
2. Power switch
Ensure that the power switch is in the position of OFF. If the plug is connected to power
receptacle while the power switch is in ON position, the demolition hammer will start operation
immediately, which can cause serious accident!
Operation
1.Press the 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 outside force. The performance will be better if it
is pressed or thrusted with properly force against the work surface.
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.
