Foredom Series SR - Manual (Page 7)

Do not bend shaft and sheath
at tight angle
When operating your Foredom tool be careful not
to bend the flexible shaft too much at either the
handpiece or motor shaft connections. Shafts and
sheaths last longer when they are used without
sharp bends. If used at angles or loops, wear will
occur at the points of greatest friction. Excessive
heat and wear will occur if the bend is too great.
Torsional Breaking Point:
Key Tip (Standard) Shaft 24-lbs.-in.
Square Drive (Heavy Duty) Shaft 50-lbs.-in.
Slip Joint (European) Shaft 24-lbs.-in.
Follow these guidelines for trouble-free use:
a 4 ″or larger radius, as shown, should be
maintained for shafts on all motors. There is no
way to avoid ultimate wear and under normal
conditions a flexible shaft machine may require
several replacement shafts and sheaths during its
lifetime. (Follow shaft and sheath assembly
instruction in the Assembly section of
this manual.)

General Guidelines
Read all the safety instructions in this
manual before operating your Foredom ®
Power Tool. Proper eye and face protection
must be worn to protect you from injuries
caused by flying debris, chips, or sparks
which might result from the work
being done.
It is possible to use rotary or chisel
handpieces not made by Foredom with
your Foredom flexible shaft power tool.
However, this is not recommended since
their function and safety cannot be
assured by Foredom.
Your Foredom motor may be operated in a
vertical or horizontal position, but it should not
be enclosed or confined so as to restrict air
circulation. If the motor is hung up above a
workbench, be sure it is fastened securely to
the wall or motor hanger. The motor may devel-
op a high operating temperature (up to 100 o F +
ambient) after prolonged use, and it will be too
hot to hold. This will not harm the motor which
is designed to operate at this temperature for
prolonged periods.
Do not force the tool
Let the speed of the tool do the work. Avoid
using too much pressure. Generally, slower
speeds are used for rougher, heavier work or
when greater control over the accessory is
required for precise, delicate work. Higher
speeds are used for buffing, cutting and
polishing. Read Accessory Recommendations
on pages 11 and 12 of this manual.
Voltage Decreases
Never operate a power tool during a perceptible
power decrease. Turn off tool and unplug until
full power is restored.
Always wear proper eye and face
protection when operating a Foredom
power tool.
Wait for motor to stop rotating before
switching between forward or reverse.
To turn motor off, remove foot from foot pedal
speed control, or turn dial speed control to “off”
position, and set rocker switch to “off” (center)
position on motor.
