Safety Instructions

Before using your Foredom®power tool, please read safety instructions.

They are for your protection and should always be followed to reduce the risk of
personal injury or damage to the tool.

• Always wear proper eye and face protection. Safety glasses or face shields
should be worn whenever you operate a Foredom or any power tool to prevent
serious eye or face injuries.

• Do not wear loose fitting clothing or jewelry. Loose clothing or jewelry can
become entangled in the rotating flexible shaft. Do not wear items such as neck
ties, necklaces, or bracelets when operating power tools. Be sure to tie back or

secure long hair.

• Secure power tool to motor hanger or work surface. Flexible shaft power
tools can vibrate during operation. The tool should be properly secured in order
to prevent it from vibrating off of the motor hanger or work bench.

• Never operate any accessory at speeds above it’s maximum rated speed.

When properly used, all of Foredom's accessories can be operated at the speed
ratings listed in the Foredom Accessory Catalog or on the accessory kits and
packages. Always find out the manufacturer's speed rating before using
accessories other than Foredom accessories.

• Never use or continue to use any accessory which appears to be damaged,
loose, vibrating, or out of balance. Inspect each accessory for cracks or flaws
before using it.

• Always insert the shank or arbor of an accessory or mandrel into the collet or
chuck of the handpiece as far as possible in order to provide proper support and
tighten the collet or chuck securely.

• Never use excessive side pressure which may tend to bend or break the
shank or arbor of an accessory. Let the speed of the accessory do the work.

• Do not stall the motor by jamming or using excessive pressure on the
accessory. This can result in damage to the motor or flexible shaft.

• Never operate the motor with the outer sheath removed from the flexible shaft.

• Always disconnect the power cord before servicing the motor or removing the

flexible shaft or sheath.

• Never operate your power tool during a perceptible power decrease. Turn
power tool off and do not use until power is fully restored.

• Use proper grounding procedures. This tool should be grounded while in use
to protect the operator from electric shock. The tool is equipped with an
approved 3-conductor cord and plug to fit the proper grounding receptacle.

Assembly Instructions

Always make sure your power tool is unplugged during assembly!

After identifying all the components of your power tool, it should be assembled in
the following manner:

Assembly and Adjustment of Flexible Shaft, Sheath & Handpiece

Proper assembly and adjustment of the flexible shaft and sheath are critical for
the correct operation of your Foredom power tool.

Important Note: The shaft and sheath should be checked and adjusted if
necessary even if you received them assembled and attached to the motor!

Please follow the directions below to assemble and adjust the shaft and sheath
and attach the handpiece.

Assembly:

1.Remove the motor connector (see figure 1). This has a left hand thread and
must be turned to the right to remove.

2.Loosen the set screw on the flexible shaft motor coupling and slide the shaft
coupling onto the motor shaft. Tighten the set screw onto the flat in the
motor shaft.

3.Put the motor connector back on the motor by sliding it up the flexible shaft and
tightening. Grease shaft (see page 12).

4.Now slide the sheath over the flexible shaft with the plain sheath fitting (not the
grooved fitting) going toward the motor and into the motor connection.

Adjustment:

5.Before attaching handpiece, shaft and sheath adjustment must be carefully
checked. Place the entire unit on a flat surface with shaft and sheath extended
straight. Adjust the exposed tip of the flexible shaft so that it extends 19mm
beyond the sheath, as shown in diagram above. This is done by moving the
sheath in or out of the motor connector. When the correct adjustment is made,
tighten the screw in the motor connector.
