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 to 

minimize the accumulation of possibly flam-

mable or explosive dust. Wear a respirator to  

pre vent the inhalation of dust particles or  

other debris.
Keep work area clean and well lighted.  

Clutter invites accidents. Good lighting helps  

prevent them. 
Reduce the risk of unintentional starting. 
Make 

sure the Speed Control knob is in the OFF posi-

tion before plugging in the power cord. Always 

disconnect the power cord before  

servicing the lathe.
Never leave the lathe running unattended. Turn 

the power off and don’t leave until it comes to a 

complete stop.
Never operate an accessory at speeds above  

its maximum speed rating. Only accessories 

rated for 7,000 RPM or higher should be used 

with the Bench Lathe. When properly used, all of 

Foredom’s accessories can be operated at the 

speeds listed in Foredom catalogs or on  

the packaging. 
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 accesso-

ry 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.

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 percepti-

ble power decrease. Turn the power tool off and 

do not use until power is fully restored.
Use proper grounding procedures. This tool is 

grounded to protect the operator from electric 

shock by providing a low resistance path to 

ground if there is an insulation failure. The tool is 

equipped with an approved 3-conductor cord and 

a 3-prong grounding type plug to fit a matching 

receptacle which is properly installed and 

grounded in accordance with local codes and 

ordinances. If the plug on the provided power 

cord does not match the AC power outlet, do not 

substitute another type power cord. Have the  

outlet changed by a qualified electrician. 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. For 

long extension cords use heavier gage sizes. Too 

small a size can cause too high a voltage drop, 

which can affect performance and cause over-

heating. For North American cords, use 18 AWG 

up to 100 ft, 16 AWG if longer (lower gage  

number, heavier cord). For European cords, use 

1.00mm sq. up to 30 meters, 1.5mm sq.  

if longer. If the power cord or extension cord  

is worn or damaged, immediately have it  

repaired by a qualified electrician, or replaced.   

Remove the power cord from the AC receptacle in 

the rear of the base to expose the fuse holder  

drawer. Use the blade of a small screwdriver in the 

slot of the fuse holder and gently pry outward. The 

active fuse is in the back of the drawer and a spare 

fuse is in the front compartment. If the glass case of 

the active fuse is darkened, the fuse is blown. From 

the underside of the drawer, push out the blown 

fuse using a small screwdriver.
Be sure that the lathe is not being overloaded, the 

line voltage is not low, and the motor shaft turns 

freely, and then replace the blown fuse with the 

spare fuse. It is a good idea to always keep a spare 

fuse in the front compartment to avoid lost time if 

there is a future blown fuse. To avoid overloading 

the motor and speed control, and possible fire dam-

age, always use the same type and ampere rating as 

the original: 3 amp, 5 x 20mm, medium time 

delay, Bussmann GMC-3A or equivalent fuse.
If, after replacement, the fuse blows when the speed 

control knob is turned to the “Start” position, the 

control or motor has a fault. The unit should be ana-

lyzed by a qualified technician, or returned to the 

factory for service. See Repair Services.

Do not use a higher ampere fuse.

Installation  

Mount the BL lathe in a clean, dry location,  

which is free of flammable vapors.
Mounting Base: The Bench Lathe comes with suc-

tion 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. 

Assembly

  

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.
Using Attachments: 
The supplied A-TM6 tapered 

spindle, and optional A-CHA-5 collet holder, 

Figure 1

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 tempo-

rarily used for connecting plugs as shown in 

sketch A to 2-prong receptacles until a  

qualified electrician installs an approved 

3-prong receptacle. 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 jurisdic-

tions, including Canada, prohibit the use of  

3 to 2 prong adapters. Where prohibited, 

they should not be used. 

Use proper fusing procedures.
