Sr Motors And Speed Controls - FOREDOM SR Series Owner's Manual

Never change motor direction while the motor is running.
P O Q
OFF – no rotation.
FORWARD – clockwise shaft rotation as
you work. It is the most commonly used
setting. Right-handed people will get
the most control in Forward.
REVERSE – counterclockwise shaft
rotation as you work .
Motor rotation
If you point a powered handpiece toward
your face as it runs the accessory will
appear to be running counterclockwise.
When the handpiece/accessory is in use
on a workpiece, forward rotation direction
is clockwise.
Forward Motor Rotation, ONLY
• Some handpieces can ONLY work in
Forward Motor Rotation, including:
Chisel or Hammer handpieces or Angle
Grinder attachment for H.30
piece. Using them in reverse can damage
the handpiece, attachment, flexible shaft,
or motor and may cause injury.
• Use the forward motor direction ONLY
for fluted burs, drills and cutters. Most
will cut efficiently only when turning in
this direction.
• Many mandrels have right-hand
threaded arbor screws which will un-
screw in the reverse direction.
• Dust and debris flies away from the
user when operated in forward in the
left hand.
• Whether you are right or left handed or
operate in forward or reverse, precautions
taken against dust and debris are always
necessary and important.
• Always securely tighten chuck nut
or chuck jaws of any handpiece with
wrench or chuck key so that it will not
come loose in the reverse or forward
operating directions.
Advantages of Reverse Rotation
• Left-handed users will have better
control in the reverse direction.
• For right handed use, dust and debris
flies away in reverse.
• Alternating motor direction can extend
the life of mounted abrasive points,
buffs, brushes, sanding bands, and
Typhoon
®
• Reverse helps with accomplishing
symmetrical grinding and carving
techniques.
• Reverse is good for "backing out"
stuck drill bits.
• Alternating motor direction makes it
easier and faster to polish metals.
• Be sure to use a mandrel with a left-
hand threaded arbor screw.
