Speed change For HM1202C only The blows per minute can be adjusted just by turning the adjusting dial. This can be done even while the tool is running. The dial is marked 1 (lowest speed) to 6 (full speed). Refer to the table below for the relationship between the number settings on the adjusting dial and the blows per minute. Number Blows on adjusting dial per minute 6 1,900 5 1,800 4 1,600 3 1,300 2 1,050 1 950 CAUTION: • The speed adjusting dial can be turned only as far as 6 and back to 1. Do not force it past 6 or 1, or the speed adjusting function may no longer work. Indicator lamp Indicator lamp 9 For HM1202C only The green power-ON indicator lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. If the indicator lamp does not light up and the tool does not start, the ON/OFF switch or the mains cord may be defective. The red service indicator lamp lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approx. 8 hours of use, the motor will automatically be shut off. ASSEMBLY CAUTION: • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. 002903 Side handle (auxiliary handle) The side handle can be swung 360° on the vertical and secured at any desired position.
