General safety rules

Every WALTER power tool is produced in accordance with applicable
standards governing the manufacture, performance and safety of power
tools.

WARNING – To reduce the risk of injury, user must read instruction manual.

Read all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury. The term “power tool”in
all of the warnings listed below refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area safety

a) Keep work area clean and well lit

. Cluttered or dark areas invite

accidents.

b) 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.

c) Keep children and bystanders away while operating a power

tool. Distractions 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.

b) 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.

c) Do not expose power tools to rain or wet 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.

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 safety equipment. Always wear eye protection. Safety

equipment such as dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate conditions will reduce
personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position

before plugging in. Carrying power tools with your finger on the

switch or plugging in 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 over-reach. 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 these devices can reduce dust-related hazards.

Operation of this power tool

a) This power tool is intended to function as a sander, wire brush,

or polisher. Read all safety warnings, instructions, illustrations
and specifications provided with this power tool. Failure to follow

all instructions listed below may result in electric shock, fire and/or
serious injury.

b) Operations such as grinding or cutting-off are not recommended

to be performed with this power tool. Operations for which the

power tool was not designed may create a hazard and cause personal
injury.

c) Do not use accessories which are not specifically designed

and recommended by Walter. Just because the accessory can be

attached to your power tool, it does not assure safe operation.

d) The rated speed of the accessory must be at least equal to the

maximum speed marked on the power tool. Accessories running

faster than their RATED SPEED can break and fly apart.

e) The outside diameter and the thickness of your accessory must

be within the capacity rating of your power tool. Incorrectly sized

accessories cannot be adequately guarded or controlled.

f) The arbour size of wheels, flanges, backing pads or any other

accessory must properly fit the spindle of the power tool.

Accessories with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.

g) Do not use a damaged accessory. Before each use inspect the

accessory such as abrasive wheels for chips and cracks, backing
pad for cracks, tear or excess wear, wire brush for loose or
cracked wires. If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After inspecting and
installing an accessory, position yourself and bystanders away
from the plane of the rotating accessory and run the power tool
at maximum no-load speed for one minute. Damaged accessories

will normally break apart during this test time.

h) Wear personal protective equipment. Depending on application,

use face shield, safety goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves and workshop apron

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your

application. 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 and in the manner intended for the
particular type of power tool, 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.

Further safety instructions for all operations

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel,
backing pad, brush or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the
accessory’s rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the work
piece, the edge of the wheel that is entering into the pinch point can dig
into the surface of the material causing the wheel to climb out or kick out.
The wheel may either jump toward or away from the operator, depending
on direction of the wheel’s movement at the point of pinching. Abrasive
wheels may also break under these conditions. Kickback is the result of
power tool misuse and/or incorrect operating procedures or conditions and
can be avoided by taking proper precautions as given below.

a) Maintain a firm grip on the power tool and position your

body and arm to allow you to resist kickback forces. Always
use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up. The operator can

control torque reactions or kickback forces, if proper precautions are
taken.

b) Never place your hand near the rotating accessory. Accessory

may kickback over your hand.

c) Do not position your body in the area where power tool will

move if kickback occurs. Kickback will propel the tool in direction

opposite to the wheel’s movement at the point of snagging.

d) Use special care when working corners, sharp edges etc. Avoid

bouncing and snagging the accessory. Corners, sharp edges or

bouncing have a tendency to snag the rotating accessory and cause
loss of control or kickback.

e) Do not attach a saw chain woodcarving blade or toothed saw

blade.

Such blades create frequent kickback and loss of control.

capable of stopping small abrasive or work piece fragments. The
eye protection must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be capable of
filtrating particles generated by your operation. Prolonged exposure
to high intensity noise may cause hearing loss.

i) Keep bystanders a safe distance away from work area.

Anyone entering the work area must wear personal protective
equipment. Fragments of work piece or of a broken accessory may

fly away and cause injury beyond immediate area of operation.

j) Hold power tool by insulated gripping surfaces only, when

performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory

contacting a “live”wire may make exposed metal parts of the power
tool “live” and shock the operator.

k) Position the cord clear of the spinning accessory. If you lose

control, the cord may be cut or snagged and your hand or arm may
be pulled into the spinning accessory.

l) Never lay the power tool down until the accessory has come to

a complete stop. The spinning accessory may grab the surface and

pull the power tool out of your control.

m) Do not run the power tool while carrying it at your side.

Accidental contact with the spinning accessory could snag your
clothing, pulling the accessory into your body.

n) Regularly clean the power tool’s air vents. The motor’s fan will

draw the dust inside the housing and excessive accumulation of
powdered metal may cause electrical hazards.

o) Do not operate the power tool near flammable materials. Sparks

could ignite these materials.

p) Do not use accessories that require liquid coolants. Using water

or other liquid coolants may result in electrocution or shock.

VOLTAGE

Before connecting the tool, make sure that the voltage shown on the rating
plate is the same as the power source.

Operating the tool on a voltage other than specified on its rating plate, may
result in personal injury to the user and damage to the unit.

EXTENSION CORD

When an extension cord is required, use one that is sufficient for the power
requirement of the tool. Extension cords of inadequate wire size cause a
serious drop in voltage, loss of power and possible motor damage. To limit
line voltage drop to a safe level, refer to the following table:

Length in meters 8 15 23 30
Length in feet 25 50 75 100
Wire size AWG

14 14 12 10

NOTE: Extension cords that are used outdoors must be approved for outdoor use.

Safety Warnings Specific for Sanding Operations:

a) Do not use excessively oversized sanding disc paper. Follow

manufacturers recommendations, when selecting sanding paper.

Larger sanding paper extending beyond the sanding pad presents
a laceration hazard and may cause snagging, tearing of the disc or
kickback.

Safety Warnings Specific for Polishing Operations:

a) Do not allow any loose portion of the polishing bonnet or its

attachment strings to spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning attachment strings can

entangle your fingers or snag on the work piece.

INTRODUCTION

Your WALTER power tool is precision built to meet the highest industrial
standards. For maximum performance and longest tool life, follow the
operating instructions and service procedures outlined in this manual.

This tool is CSA certified.
This tool is double insulated, it does not have to be grounded.

It may be safely operated from a grounded or ungrounded
receptacle. It is supplied with a 2-conductor power cord and
a polarized plug (one blade wider than the other). The plug
will fit only one way into a polarized outlet. If the plug does
not fit, have the outlet replaced by a qualified electrician. If an
extension cord is necessary, only one that is polarized must be
used. Do not change the plug in any way.

In order to maintain the safety features of the double insulation, the
housing must not be drilled to affix nameplates or the like. Self-adhesive
labels may be used for this purpose.

DIALSPEED™ SELECTOR

Select the required speed by rotating speed selector (4). Positions A-G
roughly equal the following no load revolutions per minute:

Pos. A B C D E F G
RPM 2,000 2,800 3,800 4,700 5,400 6,400 7,300

DIALSPEED™ SETTINGS

Set speed selector (4) to position D, and adjust either up or down until you
have found a speed that meets your surface finishing requirements.

The correct setting will depend on:

a) Type of material being worked
c) Amount of pressure being applied
b) Abrasive accessory being used
d) Surface finish required

DYNAMAX™ ELECTRONICS

The built-in electronic feedback circuit continuously monitors the load on
the motor and adjusts power as required to maintain a virtually constant
speed.

Should the machine be subjected to overload for an extended period, for
example when being run at a lower speed setting, the rotation speed will
be decreased electronically to protect the motor. Rather than stopping
completely, the machine will continue to run slowly to allow the motor to
cool. After a brief period, by switching the machine off and on again, it can
then be used again at the rated load.

When used for extended periods, it is quite normal for the machine to
become quite warm, with the thermal overload protection, as described
above, cutting in whenever necessary. With practice, the user will feel to
what extent the machine can be loaded at each speed setting for continuous
uninterrupted operation.)
