bout every 1000 hours or after approximately one
year of continuous operation. To access the motor,
the cover of the unit needs to be removed. Turn the
unit over and remove the screws embedded in the

end of the brush is in line and conforms to the com­mutator surface. Replacement brushes are available

to

Never operate any accessory at speeds above its
maximum speed rating. When properly used, all of
Foredom’s accessories can be operated at the
speeds listed in the Foredom Rotary Accessories
catalog or on the packaging. 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
into the collet as far as possible in order to provide
proper support. Tighten the collet or
chuck securely.

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

not use until power is fully restored.

Always replace or repair a worn cord immediately.

Use proper grounding procedures. This tool should

be grounded while in use to protect the operator

approved 3-conductor cord and a 3-prong ground­ing type 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
(or green and yellow) wire to a live terminal. If your
unit is for use on less than 150 volts, it has a plug
that looks like sketch A in Figure 1. An adapter
(sketches B and C) can be used for connecting
plugs as shown in sketch A 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.

Some jurisdictions, including Canada, prohibit the
use of 3 to 2 prong adapters. Where prohibited,
they should not be used.
