Foredom BL - Manual (Page 2)

You have purchased a fine quality power tool
which will do a wide variety of tasks difficult to
do with any other kind of power tool. Foredom ®
Power Tools are manufactured to high standards
of precision and performance and, with proper
operation and maintenance, will give you many
years of trouble-free use.
Safety Instructions
Before using your Foredom Bench Lathe, 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 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.
Always use a proper dust collection system or
wear a respirator to prevent the inhalation of dust
particles or other debris into your lungs.
Never operate an accessory at speeds above its
maximum speed rating. When properly used, all
of Foredom’s accessories can be operated at the
speeds listed in Foredom catalogs or on the
packaging. Only accessories rated for 7,000 RPM
or higher should be used with the Bench Lathe.
Always determine the manufacturer’s speed rating
before using accessories other than Foredom’s.
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 collet holder chuck or
chuck arbor) as far as possible in order to provide
proper support. Tighten the collet or
chuck securely.
Always make sure that accessory tightening tools
such as the pin and wrench are removed before the
lathe is turned on.
Assembly Instructions
BL Bench Lathes have 5/16” (8mm) straight motor
shafts and come with A-TM5 (left hand) and A-TM6
(right hand) tapered spindles. These precision
made spindles are suitable for speeds of 500 to
7,000 RPM. Similar spindles, supplied for slower
speed polishing motors, often do not run as true
which can cause vibration and be a potential
hazard. Using spindles and other precision
accessories supplied for slower speed motors
is not recommended with this bench lathe.
Mounting Base: The Bench Lathe comes with
suction cup feet that help to secure the lathe to a
smooth work surface. To further prevent movement
while pressure is being applied to a buff or wheel,
the base should be bolted or screwed down to a
solid work bench or table. Use the four mounting
holes in the base for this purpose.
Using Attachments: The supplied A-TM6 tapered
spindle, and optional A-CHA-5 collet holder,
A-JCA-2 chuck arbor, A-WM6 wheel mandrel and
S.B0 flexades ® are right hand side accessories,
intended for use on the right hand side of the lathe
as you face it. Do not use them on the left side as
buff, wheel or tool may unscrew under load. The
supplied A-TM5 tapered spindle and optional
A-WM-5 wheel mandrel is intended for use on the
left side only. (Every spindle and mandrel is
marked with an R or L to indicate left or
right hand.)
Attach the spindles or mandrels by sliding them
onto the motor shaft until there is only a 1/8 ″ space
between the motor housing and inside edge of the
spindle or mandrel. Be sure that the two set screws
line up with the flat on the motor shaft. Tighten
both screws securely with supplied hex key.
See Figure 2 for mounting rubber wheels or other
accessories with 1/4 ″ diameter center holes on
A-WM-6 wheel mandrel.
Use only 115 Volt AC 60 Hz for M.BL and use only
230 Volt AC 50 Hz for M.BL-2CE. Run the lathe at
slow speed without a buff (or wheel) to see that the
spindles, mandrel, or collet holder on the lathe
are running true.
Never use a buff, brush, abrasive wheel, or any
other accessory that is rated under 7,000 RPM.
Never use one that appears to wobble or vibrate.
It could damage the lathe or injure you.
Never use buffs over 4 ″ in diameter.
Never use a grinding wheel over 2 ″ diameter nor
rubber bonded wheels over 3 ″ in diameter.
Please refer to Figure 2 for the proper mounting
procedure for wheels or brushes on the A-WM-6
(or A-WM-5) mandrel.
Tapered Spindles: For use with cotton, felt,
and chamois buffs with shellac hardened leather or
lead centers. Also for felt inside ring buffs mounted
on wooden mandrels, EXL Wheels, Radial Bristle
Discs (with A-4561 or A-4562 tapered spindle
adapters), and any 3 ″ or smaller wheels with arbor
holes up to 7/16 ″. Mounting Wheels onto Tapered
Spindles: Turn lathe on and run at low speed.
Align arbor hole of accessory with screw-like
threads of tapered spindle. The accessory will self
tighten as it travels up the spindle threads. To
remove, turn lathe off and manually unscrew
your wheel or buff.
Collet Holder: Loosen the two hex or allen screws
on A-CHA-5 Collet Holder and slide onto exposed
motor shaft of BL Lathe. Position screws over the
flat area of the shaft and re-tighten. Changing
Collets and Accessories: The Collet Holder comes
with 3/32 ″, 1/8″ and 1/4″ collets for use with
accessories and mandrels with 3/32 ″, 1/8″ and
1/4 ″ diameter shanks. The 1/4″ collet typically
comes installed. To switch out a collet and/or an
accessory with a different shank size, insert
supplied pin with safety spring into hole next to
the two set screws. Insert the wrench onto the flats
at the tip of the chuck nut and unscrew nut while
holding pin in place to keep spindle from turning.
Remove chuck nut and switch out collet. This may
require the use of a needle nose pliers. Replace
chuck nut and tighten after installing the shank of
the desired accessory or mandrel. Never tighten a
chuck nut without an accessory installed, as
damage to the collet may occur.
Chuck Arbor: Loosen the two hex or allen screws
on A-JCA-2 Chuck Arbor and slide onto exposed
motor shaft of BL Lathe. Position screws over the
flat area of the shaft and re-tighten. Changing
Collets and Accessories: The A-JCA-2 has a
geared 3-jaw #0 chuck. Open chuck jaws as far
as necessary with key provided. Insert shank of
accessory fully into the chuck. Tighten each of the
jaws with chuck key until accessory is secure and
centered. If accessory does not run true, reopen
jaws, rotate accessory and retighten. To release
accessory, simply reopen chuck jaws with key
and pull out accessory. Figure 1
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.
Do not overload the lathe by jamming or using
excessive pressure on the polishing wheel, buff
wheel, or accessory. Do not apply long time
continuous loading. This can result in damage to
the lathe.
Never operate your power tool during a perceptible
power decrease. Turn the power tool off and do not
use until power is fully restored.
Use proper fusing procedures. The fuse holder is
located on the rear of the base. If a fuse blows,
make sure lathe is not being overloaded, line volt-
age is not low, and motor shaft turns freely.
Replace fuse with same type and ampere rating.
Use type 3AG “slow blow” fuses, 3 Amp for model
M.BL and 1.5 Amp for model M.BL-2CE.
Do not use a higher ampere fuse.
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
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. Use only
3-wire extension cords that have 3-prong ground-
ing 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.
