General Power Tool Safety Warnings

WARNING! Read all safety warnings

The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery­operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well lit.

b) Do not operate power tools in explosive

c) Keep children and bystanders away while

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet.

b) Avoid body contact with earthed or

c) Do not expose power tools to rain or wet

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

Cluttered or dark areas invite accidents.

atmospheres, such as in the presence of
flammable liquids, gases or dust. Power

tools create sparks which may ignite the dust
or fumes.

operating a power tool. Distractions can
cause you to lose control.

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.

grounded surfaces such as pipes,
radiators, ranges and refrigerators. There

is an increased risk of electric shock if your
body is earthed or grounded.

conditions. Water entering a power tool will
increase the risk of electric shock.

d) 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.

e) 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.

f) If operating a power tool in a damp

location 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. A moment of

inattention while operating power tools may
result in serious personal injury.

b) 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.

c) 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 energising power tools that
have the switch on invites accidents.

d) 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.

e) Do not overreach. Keep proper

footing and balance at all times. This
enables better control of the power tool in
unexpected situations.

f) Dress properly. Do not wear loose

clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair

can be caught in moving parts.

g) If devices are provided for the connection

of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce

dust-related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the

correct power tool for your application.

4

ENGLISH

The correct power tool will do the job
better and safer at the rate for which it
was designed.

b) 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.

c) 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.

d) 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.

e) Maintain power 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.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.

g) 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.

5) SERVICE

a) 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.

ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of

injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set­ups or when making repairs. Be sure

the trigger switch is in the OFF position.
An accidental start-up can cause injury.

Fitting Sanding Discs (Fig. 2)

The tool uses 125 mm (5") hook and loop sanding
discs with an 8 hole dust extraction pattern.

1. Place the tool on a table, sanding pad (f) up.

2. Place the sanding disc (i) directly on top of the
sanding pad.

3. Hold the sanding pad with one hand and align
the dust extraction holes.

4. Press the disc firmly onto the sanding pad.

ENGLISH

Setting the Electronic Speed Control
Dial (Fig. 1)

The speed is infinitely variable from 8,000–12,000
min-1 using the electronic speed control dial (b).

Turn the electronic speed control dial to the required
level. The correct setting, however, is a matter of
experience.

Generally, harder materials require a higher setting.

Dust Extraction (Fig. 3, 4)

WARNING: Since woodworking with a

sander produces dust, always install a
dust bag designed in compliance with
the applicable directives regarding dust
emission.

WARNING: Do not use a dust bag or

vacuum extractor without proper spark
protection when sanding metal.

Your sander has two dust extraction methods: a
built-in outlet (c) which allows either the supplied
dust bag (d) or a shop vacuum system to be
connected; and a dust skirt (n, Fig. 4). The built-in
outlet utilizes the DEWALT airlock connection making
it compatible with the DEWALT dust extractor and
airlock accessory DWV9000.

TO ATTACH THE DUST BAG

1. While holding the sander, fit the dust bag collar
(e) to the outlet (c) as shown in Figure 3.

2. Turn the collar (e) clockwise to lock the dust
bag (d) in place.

TO EMPTY THE DUST BAG

NOTE: Be sure to wear approved eye protection
and approved dust mask when performing this
procedure.

For efficient dust extraction, empty the dust collector
when it is about one third full.

1. While holding the sander, turn the collar (e)
anticlockwise to unlock the dust bag (d).

2. Remove dust bag from the sander and gently
shake or tap the dust bag to empty.

3. Reattach the dust bag back onto the outlet and
lock into place by turning the dust bag collar
clockwise.

You may notice that all the dust will not come
free from the bag. This will not affect sanding
performance but will reduce the sander’s dust
collection efficiency. To restore your sander’s dust
collection efficiency, depress the spring inside the
dust bag when you are emptying it and tap it on the
side of the waste bin or dust receptacle.

ENGLISH

Sanding

Start with the coarsest grit size.

As the tool produces small abrasion marks in all
directions, it is not necessary to sand with the grain.

Check your work at short intervals.

Always switch off the tool when work is finished and
before unplugging.

Lubrication

Your power tool requires no additional lubrication.

MAINTENANCE

Your DEWALT power tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.

WARNING: To reduce the risk of

injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing
set-ups or when making repairs.

Be sure the trigger switch is in the OFF
position. An accidental start-up can
cause injury.

Replacing the Sanding Pad and the
Speed Limiter Belt (Fig. 4)

Your sander is equipped with a replaceable belt (m)
which is located between the pad (f) and the sander
body (j). It is designed to control the pad speed
while the unit is off the work surface. The belt and
the sanding pad (f) are designed to be consumable
parts and will occasionally need to be replaced.
The sanding pad needs replacement when signs
of wear become evident. Replacement of the belt
is necessary when the pad speed increases very
dramatically when the unit is lifted from the work
surface. These parts are available at extra cost from
your local dealer or authorised D
centre.

1. Holding the platen firmly, remove the four
screws (o) from the bottom of the pad.

2. Remove the pad (f).

3. Replace worn or damaged belt (m) by wrapping
it around the shoulder screw (k) and bearing
retainer (l) as shown in Figure4.

4. Reinstall pad (replace with new pad if
necessary). Replace the four screws (o). Be
careful not to over-tighten screws.
