Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
7.
In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-

immediately after operation; they may be
extremely hot and could burn your skin.

toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
