Dremel 670 Saw User Manual


 
coasting blade will cause the saw to cut whatever
is in its path. Be aware of the time it takes for the
blade to stop after switch is turned off.
NEVER hold piece being cut in your hands or
across your leg. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
Always use blades with correct size and shape
arbor holes. Blades that do not match the
mounting hardware of the saw will run
eccentrically, causing loss of control.
Do not run the tool while carrying it at your side.
Lower guard may be opened by a contact with
your clothing. Accidental contact with the spinning
saw blade could result in serious personal injury.
Know how to turn slide switch “OFF” in an
emergency. If switch cannot turn “OFF” the tool
quickly, unplug the tool immediately.
CAUSES AND OPERATOR PREVENTION OF KICKBACK:
Kickback is a sudden reaction to a pinched, bound
or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward
the operator.
When the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward
the operator.
If the blade becomes twisted or misaligned in the
cut,the teeth at the back edge of the blade can dig
into the top surface of the wood causing the blade
to climb out of the kerf and jump back toward
the operator.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
Maintain a firm grip with both hands on the tool
and position your body and arm to allow you to
resist KICKBACK forces. KICKBACK forces can be
controlled by the operator, if proper precautions
are taken.
When blade is binding, or when interrupting a
cut for any reason, turn off the tool and hold the
tool motionless in the material until the blade
comes to a complete stop. Never attempt to
remove the saw from the work or pull the tool
backward while the blade is in motion or
