_,WARNING: Some dust created by power sanding, sawing, grinding, drilling
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 chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemical: work in a well ventilated
area, and work with approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.

GENERAL POWER TOOL SAFETY WARNINGS
,_ WARNING: Read aii safety warnings and 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.
The term "power tool" in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas 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.
ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adaptor plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of
electric shock.
Avoid body contact with earthed or 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 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 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 location is unavoidable, use a
ground fault circuit interrupter (GFCl) protected supply. Use of a GFCI
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 tool while 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, or hearing protection used for appropriate conditions will reduce
personal injuries.
* Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your finger on the switch or
energizing in power tools that have the switch on invites accidents.
* Remove any adjusting key or wrench before turning 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. This
enables better control of the power tool in unexpected situations.
*Dress properly. Do not wear loose clothing or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
* If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used. Use
of these devices can reduce dust-related hazards.
POWER TOOL USE AND CARE
* Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and more safely at
the rate for which it was designed.
* Do not use the power tool if the switch does not turn it on and off. 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
from the power tool 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.

= Maintainpower tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tool's operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained power tools.
= Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
= Use the power tool, accessories and tool bits etc., in accordance with
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
SERVICE
Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
Follow instructions in the Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance instructions may create
a risk of shock or injury.
SPECiFiC SAFETY RULES FOR DETAIL SANDER
= Hold power tools by their insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will also make exposed metal parts of
the tool "live" and shock the operator.
= Know your power tool. Read the operator's manual carefully. Learn its
applications and limitations, as well as the specific potential hazards
elated to this tool. Following this rule will reduce the risk of electric shock,
fire or serious injury.
= Always wear safety glasses with side shields. Everyday glasses have
only impact resistant lenses. They are not safety glasses. Following this
rule will reduce the risk of eye injury.
= Protect your lungs. Wear a face or dust mask if the operation is dusty.
Following this rule will reduce the risk of serious personal injury.
= Protect your hearing. Wear hearing protection during extended periods
of operation. Following this rule will reduce the risk of serious person injury.

SELECTING THE CORRECT GRIT OF SANDPAPER
Use a coarse grit to sand down rough finishes, medium grit to smooth the work
and fine grit to finish off.
It is best to make a trial run on a scrap piece of material to determine the
optimum grades of sandpaper for a particular job.
SANDPAPER GRIT CHART
Grit Type Example of use
80-100 Coarse Paint removal, rough surface preparation
(e.g., non-planed wood)
120-150 Medium Surface preparation planed wood
180-220 Fine Sanding between coats
SANDING
This detail sander can be used for most sanding operations on materials such
as wood, plastic, metal and painted surfaces. The removal rate and the sanding
pattern are determined by the choice of sandpaper and the work surface.
A sandpaper sheet that has been used for metal should not be used for
other materials.
3.
4.
Always attach the dust bag or a suitable adapter and vacuum when sanding
with the detail sander
WARNING: Do not touch sander vents after prolonged use; the gear box
could be very hot.
1. Wear safety goggles, a dust mask, and hearing protection.
2. Apply uniform sanding pressure to extend the life of the sandpapers.
Intensifying the sanding pressure does not lead to an increase of the sanding
capacity, but instead it increases wear on the machine and the sandpaper.
Use only the tip or an edge of the sandpaper for precise sanding of edges,
corners and hard to reach areas.
When selectively sanding on one spot, the sandpaper can heat up
considerably. Remove the tool from the surface periodically to permit the
sandpaper to cool down.
_, CAUTION: Where possible, clamp smaller workpieces to a workbench.
