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.
• Always use a proper dust collection system or wear a respirator to prevent the
inhalation of dust particles or other debris into your lungs.
• Do not wear loose fitting clothing or jewelry. Loose clothing or jewelry can become
entangled in the rotating bur
when operating power tools. Be sure to
• Secure power tool to motor hanger or work surface. Substantial torque is generated
when starting or accelerating it with the foot pedal. Securely attach it to the motor hanger
to prevent it from “jumping off” the hook.

. Do not wear items such as neck ties,necklaces, or bracelets
tie back or secure long hair.
• Never operate any accessory at speeds above it’s maximum rated speed. All of Foredom's
accessories, when properly used, can be operated at the speed ratings listed in the Foredom
Accessory Catalog or on the accessory kits and packages.
Always find out the manufactur-
er's speed rating before using other accessories.
• Never use or continue to use any accessory which appears to be damaged, loose, vibrat
ing, or out of balance.
Inspect each accessory for cracks or flaws before using it. Avoid
knots, imperfections in the wood or metal objects like nails, which could damage or catch
the accessory. Let the speed of the tool do the work rather than apply heavy pressure to
the accessory.
• Always insert the shank or shaft 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 shaft 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. The green (or green and yellow) conductor in
the cord is the grounding wire. Never connect the green wire to a live terminal. It has a plug
that looks like sketch A in the diagram below. An adapter, sketches B and C, can be used for
connecting plugs as shown below to 2-prong receptacles. The green colored rigid ear, lug,
etc., extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Use only 3-wire extension cords that have 3-prong grounding type
plugs and3-pole receptacles that accept the tool's plug.
