Foredom M.402 - Manual (Page 2)

Do not stall the motor by jamming or using
excessive pressure on the Typhoon ® bur or other
accessory. This can result in damage to the motor.
Never operate your Arch Trimmer during a perce
tible power decrease. Turn power tool off and do
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
from electric shock. The tool is equipped with an
approved 3-conductor cord and a 3-prong ground-
ing 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. Use only 3-wire extension
cords that have 3-prong grounding type plugs and
3-pole type plugs and 3-pole receptacles that accept
the tool’s plug. Always disconnect the power cord
before servicing the lathe. Never use in an area
where flammable vapors are present.
Safety Instructions
The Foredom ® Arch Trimmer is manufactured to
high standards of precision and performance and,
with proper use and maintenance, will give you
years of trouble-free operation.
Before using your Foredom Arch Trimmer, please
read all 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 use the safety shield.
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 clothing or jewelry, and be sure
to tie back long hair.
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 dam-
aged, 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
do the work.

Cleaning, Maintenance, and Parts
Cleaning: At least once a week you should remove
and clean the area beneath the stainless steel work
surface to insure proper air flow and prevent
build-up of dust or powder around the motor shaft.
If you do more than 5 models a day you should
clean the Model 400 Arch Trimmer at the end of
each day. Remove the stainless steel work surface
and vacuum the dust. Remove the collet or chuck
and vacuum the collet holder socket in the spindle.
Clean the chuck nut and collet. Wipe the Collet with
light lubricating oil before replacing.
Lubrication: The Foredom Arch Trimmer has
pre-lubricated ball bearings and a sealed dust-proof
motor housing that do not require any lubrication.
