DIALSPEED™ SELECTOR
Select the required speed by rotating speed selector (4). Positions A-G
roughly equal the following no load revolutions per minute:
Pos.
A
B
C
D
E
F
G
RPM
2,000 2,800 3,800 4,700 5,400 6,400 7,300
DIALSPEED™ SETTINGS
Set speed selector (4) to position D, and adjust either up or down until you
have found a speed that meets your surface finishing requirements.
The correct setting will depend on:
a)
Type of material being worked
c)
Amount of pressure being applied
b)
Abrasive accessory being used
d)
Surface finish required
DYNAMAX™ ELECTRONICS
The built-in electronic feedback circuit continuously monitors the load on
the motor and adjusts power as required to maintain a virtually constant
speed.
Should the machine be subjected to overload for an extended period, for
example when being run at a lower speed setting, the rotation speed will
be decreased electronically to protect the motor. Rather than stopping
completely, the machine will continue to run slowly to allow the motor to
cool. After a brief period, by switching the machine off and on again, it can
then be used again at the rated load.
When used for extended periods, it is quite normal for the machine to
become quite warm, with the thermal overload protection, as described
above, cutting in whenever necessary. With practice, the user will feel to
what extent the machine can be loaded at each speed setting for continuous
uninterrupted operation.)

VOLTAGE
Before connecting the tool, make sure that the voltage shown on the rating plate is
the same as the power source.
Operating the tool on a voltage other than specified on its rating plate, may result in
personal injury to the user and damage to the unit.
EXTENSION CORD
When an extension cord is required, use one that is sufficient for the power
requirement of the tool. Extension cords of inadequate wire size cause a serious
drop in voltage, loss of power and possible motor damage. To limit line voltage drop
to a safe level, refer to the following table:

NOTE: Extension cords that are used outdoors must be approved for outdoor use.

SIDE HANDLE
Side handle (1) may be mounted on either side of the gear housing for greater
convenience in both right and left hand operation. For reasons of safety and better
control, the side handle must always be used.

SPINDLE LOCK
To mount or remove abrasive wheels and accessories, disconnect the
machine from the power supply. Depress spindle lock button (2), while
rotating the spindle by hand until the locking mechanism is engaged. With
the spindle in a locked position, use the appropriate pin key or open-end
spanner for the accessory being utilized. Never depress the locking button
while the tool is turned on.
SWITCH
To start, push locking switch (3) forward, locking it in the ON position.
To stop, press up on the long part of the switch, returning it to the OFF
position.
