Failure to follow
The term “power tool” in the warnings refers
to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1 WORK AREA SAFETY
a)
Keep work area clean and well lit.

Do not operate power tools in explosive
b)
atmospheres, such as in the presence
Clut-
of flammable liquids, gases or dust.
Power tools create sparks which may ignite
the dust or fumes.
Keep children and bystanders away
c)
while operating a power tool.
Distrac-
tions can cause you to lose control.
2 ELECTRICAL SAFETY
a)
Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with
earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or
b)
grounded surfaces, such as pipes, radiators, ranges and refrigerators.
There is
an increased risk of electric shock if your
body is earthed or grounded.
Do not expose power tools to rain or
c)
wet conditions.
Water entering a power
tool will increase the risk of electric shock.
Do not abuse the cord. Never use the
d)
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,
e)
use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor
use reduces the risk of electric shock.
If operating a power tool in a damp lo-
f)
cation is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
3 PERSONAL SAFETY
a)
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.

Protective
equipment such as dust mask, non skid

personal injuries.
Prevent unintentional starting. Ensure
c)
the switch is in the off-position before
connecting to power source and/or

Use of dust collection
can reduce dust-related hazards.
4 POWER TOOL USE AND CARE

Machine-related safety instructions
–
Harmful/toxic dusts can be produced
during your work (e.g. lead-containing
paint, some types of wood and metal).
Contact with these dusts, especially inhaling
them, can represent a hazard for operating
personnel or persons in the vicinity. Comply
with the safety regulations that apply in
your country. Connect the electric power
tool to a suitable extraction system.
To protect your health, wear a P2 protective mask.
Always wear protective goggles to protect against sanding hazards.
Prevent liquid polish from entering the

Metal processing
When processing metal, the following
measures must be taken for safety
reasons:
– Install an upstream residual-current cir-
cuit-breaker (FIG, PRCD).
– Connect the machine to a suitable dust ex-
tractor.
– Regularly remove dust deposits in the mo-
tor housing.
Wear protective goggles.
Health hazard by dust
WARNING!
power sanding, sawing, grinding, drill-
ing and other construction activities
contains chemicals known (to the State of
California) to cause cancer, birth defects or
other reproductive harm. Some examples of
these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemical-
lytreated lumber.
Various dust created by
The risk from these exposures varies, depending on
how often you do this type
of work. To reduce your exposure to these chemicals:
work in a well ventilated
8
area, and work with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles.
Wash hands after handling.

If an extension cord is required, it must have
sufficient cross-section to prevent an excessive drop in voltage or overheating. An excessive drop in voltage reduces the output

Smooth start-up
The electronically controlled smooth start-up
ensures that the machine starts up jolt-free.
Speed control
You can regulate the speed steplessly with
the adjusting wheel
(see Technical data). This enables you to optimise the cutting speed to suit the surface
(see table).
Constant speed
The preselected motor speed remains constant through electronic control to ensure a
uniform cutting speed even when under load.

Work in corners and on edges tends to subject the tip to increased stress and results in
increased heat development. In such cases,
work with reduced contact pressure.

Dust can be hazardous to health. Always
work with a dust extractor.

WARNING
Risk of injury
X
Always secure the workpiece in such a
manner that it cannot move while being
machined.
Observe the following instructions:
– Do not overload the machine by pressing
with excessive force! The best sanding re-
sults are achieved with moderate application pressure. The sanding capacity and
quality are mainly dependent on the selection of the correct abrasive.
– Hold the machine with two hands, one on
the motor housing and one on the gear
head.

Service and maintenance
rupted automatically and the machine comes
to a standstill.
Any maintenance or repair work that
requires opening of the motor or gear
housing should only be carried out by
an authorised Customer Service Centre
(name supplied by your dealer)!
X
Maintenance or repair work carried out by
an unauthorised person can lead to the
wrong connection of the power leads or
other components, which in turn can lead
to accidents with serious consequences.
WARNING
To prevent accidents, always remove
the plug from the power supply socket
before carrying out any maintenance or
repair work on the tool!
X
Do not use compressed air to clean the
electrical tool! Do not try to clean parts inside the tool in this way, as you could let
foreign objects in through the openings of
the tool housing.
Sanding pad brake
The rubber collar
and the stop ring
prevent uncontrolled excessive turning of the
sanding pad during eccentric motion (fine
sanding). As these parts are subject to wear
in the course of time, they must be replaced
when reduced braking force is observed (for
order no., see spare parts list).

Accessories
Use only original Festool accessories and
Festool consumable material intended for
this machine because these components are
designed specifically for the machine. Using
accessories and consumable material from
other suppliers will most likely affect the
quality of your working results and limit any
warranty claims. Machine wear or your own
personal workload may increase depending
on the application. Protect yourself and your
machine, and preserve your warranty claims
by always using original Festool accessories
and Festool consumable material!
Only use original sanding and polishing pads
from Festool. Low-quality sanding and pol-
ishing pads may cause serious machine imbalance that decreases the quality of the
working results and increases machine wear.
The order numbers of the accessories and tools
can be found in the Festool catalogue or on the
Internet under "www.festoolusa.com".
Systainer
Many Festool products are shipped in a
unique system container, called "Systainer".
This provides protection and storage for the
tool and accessories. The Systainers are
stackable and can be interlocked together.
They also can be interlocked atop Festool CT
dust extractors.
