② When cutting the buried pipe, the saw blade may be caught in the pipe by influence of earth
pressure. In this case, use a magnet-attached wedge at the cutting port．
③ In case of which the blade is stuck between the pipes,
・Release Trigger switch immediately.
・Unlock On-lock and stop the motor.
・Drive in Magnet-attached wedge or Chisel and remove the blade.
■ How to use the magnet-attached wedge
① Drive a magnet-attached wedge at the position
where the back of the guide plate is about 30
㎜ from the cutting start position.（For the thin
pipe, remove the guide plate at the position
where the back of saw blade is at about 30 ㎜
from the cutting start position, and drive the
magnet-attached wedge．）
② If the wedge cannot be driven by hand, use a
plastic hammer etc.
