PRODUCT DESCRIPTION
From low-viscosity paints to high-viscosity mortars these
electric mixers will get your job done quicker, safer and eas-
ier than a conventional ½” drill motor. e ergonomically
designed handles and the variable 2-speed motor with soft-
start make the job quicker, safer and easier. e heavy-duty
gearbox and high-torque motor will outlast a standard ½”
drill motor by 3-4 times.
e machines have been designed to mix liquid and powder
building materials such as paint, mortar, adhesive, plaster,
epoxy and similar substances.
e relevant mixing action depends on the consistency of
the materials and the quantity that has to be mixed. is
must be set up for the appropriate mixing paddles.
You must abide by certain safety precautions when
using the equipment, in order to prevent injuries
and damages from occurring. Therefore you must
always read through this operating manual care-
fully.

GENERAL SAFETY RULES
WARNING! Read all safety warnings and all Instructions.
Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
e term “power tool” in the warnings refers to your elec-
tric power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark ar-
eas invite accidents.
• Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the
dust or fumes.
• Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.

ELECTRIC SAFETY
• Power tool plugs must match the outlet: Never mod-
ify the plug in any way. Do not use any adapter plugs
grounded power tools. Unmodified plugs and match-
ing outlets will reduce risk of electric shock.
• Avoid body contact with grounded surfaces, such as
pipes, radiators, ranges and refrigerators. ere is an
increased risk of electric shock if your body is ground-
ed.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not, use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
• Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat. and/or hearing protec-
tion used for appropriate conditions will reduce per-
sonal injuries. .
• Prevent unintentional starting. Make sure the switch is
in the off-position before connecting to power source.
• Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
• Remove any adjusting key or wrench before starting
the power tool. on. A wrench or a key left attached to
a rotating part of the power tool may result in personal
injury.
• Do not overreach. Keep proper footing and balance at
all times. is enables better control of the power tool
in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from mov-
ing parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
• If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can
reduce dust-related hazards.
POWER TOOL USE AND CARE
• Use the correct power tool for your application. e
correct power tool will do the job better and safer at the
rate for which it was designed.
• Do not use the power tool if the switch does not turn
it on and off properly. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
• Disconnect the plug from the power source and/or the
battery pack before making any adjustments, changing
accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power
tool accidentally.
• Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
