Speed change (Fig. 7)
To change the speed, first switch off the tool and then slide the speed change lever to the "A" side (2) for high speed or
"B" side (1) for low speed. Be sure that the speed change lever is set to the correct position before operation. Use the
right speed for your job.
CAUTION:
• Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever
positioned half-way between the "A" side (2) and "B" side (1), the tool may be damaged.
• Do not use the speed change lever while the tool is running. The tool may be damaged.
