DRUM MOTOR MAGNETIC SWITCH
This model 15-250 M1 drum sander is equiped with a
MAGNETIC SAFETY SWITCH ,
. located on the control
box, designed to protect the unit and the user from
power surges, power outages and unwanted or unin-
tentional start-up.
The switch assembly is equipped with a GREEN “START”
button,
, and a RED spring loaded “STOP” button,
.
Once the RED “STOP” button has been pressed, the
machine can only be started by turning the BLACK
inner part of the button to the right to release the stop
button,
.

This model 15-250 M1 is also equiped with a simple
ON/OFF switch for the conveyor motor, featuring a
removable lock out safety key.
To start the conveyor belt, insert the safety key,
, and
lift the switch up,
. To stop the machine, pull the switch
down,
.
To prevent unauthorized use or unintentional start-up,
remove the safety key and store it in a safe place
whenever the sander is not in use.
ON/OFF POWER SWITCHES
This sander is equipped with 2 different ON/OFF power switches: one magnetic switch for the drums motor and one
switch with a safety key for the conveyor motor.
OVERLOAD PROTECTION
The magnetic safety switch on this sander is equipped with an overload protection feature. To prevent an electrical
overload from damaging the motor, in the event of a spike in line voltage or amperage draw, the internal overload
protector will automatically be tripped, thereby cutting off power to the motor.
Note: The most common causes of such overloads are:
1.
Overworking the motor by attempting to remove too much material in a single pass, thereby causing an in-
crease in power consumption and a spike in amperage draw.
2.
An electrical extension cord that is too long or not the correct gauge of wire, which can also cause an increase
in amperage draw. If an electric extension cord must be used, follow the instructions and refer to the chart in
the electrical requirements section at the beginning of this manual.
3.
Overworked circuit caused by operating on a circuit that is close to its amperage draw capacity. Make sure the
circuit being used is capable of handling the amperage draw from this machine as well as any other electrical
devices operating on the same circuit. If you are unsure, consult a qualified electrician.
To reset the overload protection switch after it has been tripped proceed as follows:
Remove the switch key and store it in a safe place, out of the reach of children, whenever the sander is not in use.
To avoid unexpected or unintentional start-up be certain that both of the power switches have been set to the off
position before re-setting the overload protection switch.
