PRECAUTIONS ON USING THE MACHINE
1. Do not use the power tool for explosive materials
(e. g., easily inflammable solvents).
Power tools produce sparks which could ignite
developing vapours.
2. In case the power tool should fall into the material to
be stirred, pull the plug immediately and have the
power tool checked by an after-sales service agent.
Material that has penetrated the power tool can cause
damage and lead to an electric shock.
3. When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
The power tool is guided more secure with both
hands.
4. Do not work materials containing asbestos.
Asbestos is considered carcinogenic.

APPLICATIONS
Mixing pulverised building materials such as mortar,
plaster, adhesives, as well as solvent-free paint,
varnish and similar substances.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, inviting serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.

5. Take protective measures when dust can develop
during working that is harmful to one's health,
combustible or explosive.
Example: Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip extraction
when connectable.
6. Always wait until the machine has come to a
complete stop before placing it down.
The tool insert can jam and lead to loss of control
over the power tool.
7. Never use the machine with a damaged cable. Do
not touch the damaged cable and pull the mains
plug when the cable is damaged while working.
Damaged cables increase the risk of an electric shock.
8. When operating a mixer with wet material avoid
splashes up to the motor part.
9. Connect machines that are used in the open via a
residual current device (RCD).

CAUTION
To avoid serious accident, ensure the switch is in the
OFF position, and the power source is disconnected.
(1) Screw the stirrer paddle onto the spindle. Hold the
spindle in place with wrench and turn the stirrer
paddle with another wrench in the clockwise direction
(viewed from the front side). Tighten securely.
(2) The stirrer paddle is disassembled in reverse order.
5. High-speed/Low-speed changeover
Prior to changing speed, ensure that the switch is in
the OFF position, and the machine has come to a
complete stop.
To change speed, rotate the gear shift dial as indicated
by the arrow in Fig. 3. The numeral "1" engraved on
the machine body denotes low speed, the numeral
"2" denotes high speed.
If it is hard to turn the gear shift dial, turn the spindle
slightly in either direction and then turn the gear shift
dial again.
HOW TO USE
1. Switch operation (Fig. 4)
When the trigger is depressed, the tool rotates. When
the trigger is released, the tool stops.
Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
2. Adjusting the speed
The desired rotation speed can be pre-selected with
the speed control dial. (Fig. 5)
