1. Check if saw blade is tightened
While the saw blade is tightened securely for
immediate use when it is assembled at the factory,
be sure to check it out again for caution's sake. A
bolt can be tightened when it is turned clockwise.
Use the provided hex. bar wrench 5 mm to check it
out. For further details, refer to the item of [PRIOR TO
OPERATION] on Page 15.
2. Check if the lever is tightened
If the lever to adjust cutting depth (Fig. 12) is loose,
injury can result. Make sure that it is tightened
securely.
3. Operation of switch (Fig. 20)
(switch trigger and light switch)
For safe operation of the machine, a "lock-off button"
is provided on the side of a handle.
If the "switch trigger" is pulled in a state where "lock-
off button" is pressed in the direction of the arrow
mark, the main switch can be turned ON.
After the switch is on, the saw blade will continue to
operate as long as you pull on the switch trigger, even
if you release the lock-off button. Also, the LED light
will remain lit for Always-ON mode as well as during
SW interlocked mode.
