GENERAL SAFETY RULES
Every WALTER power tool is produced in accordance with applicable
standards governing the manufacture, performance and safety of power
tools.
WARNING: Read all instructions. Failure to follow all
instructions listed below may result in electric shock, re and/
or serious injury.
The term “power tool” in all of the warnings listed below refers to the
Dialspeed straight grinders model 6141 and model 6145.
1) Work area
a) Keep work area clean and well lit. Cluttered and dark areas
invite accidents.
b) Do not operate power tools in explosive atmospheres, such
as in the presence of ammable 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. Unmodied 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 inuence 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 o-
position before plugging in. Carrying power tools with your
nger 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 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 these devices 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. 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 o. 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.
EN

e) Maintain power tools. Check for misalignment or binding of
moving parts, breakage of parts and any other condition that
may aect the power tools 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 qualied repair person using
only identical replacement parts. This will ensure that the safety of
the power tool is maintained.
6) Safety instructions for all operations
Safety Warnings Common for Deburring, Fitting, Wire Brushing,
Polishing or Abrasive Cutting-O Operations:
a) These power tools are intended to function as tting (6141 only),
deburring (6141 only), brushing (6145 only) abrasive cutting-o
(6145 only) or polishing tool (6145 only). Read all safety warnings,
instructions and specications provided with this power tool.
Failure to follow all instructions listed below may result in electric
shock, re and/or serious injury.
b) Operations such as brushing, polishing or cutting are not
recommended to be performed on the 6141. Operations such as
deburring and tting are not recommended to be performed on
the 6145. 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 specically designed
and recommended by the tool manufacturer. 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 y apart.
EN
7DialSpeed
TM
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, anges, backing pads or any other
accessory must properly t 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
capable of stopping small abrasive or workpiece fragments. The
eye protection must be capable of stopping ying debris generated
by various operations. The dust mask or respirator must be capable
of ltrating 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 workpiece or of a broken accessory may
y away and cause injury beyond immediate area of operation.
j) Hold power tool by insulated gripping surfaces only when
performing as the 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 ammable materials. Sparks
could ignite these materials.
p) Do not use accessories that require liquid coolants. Using water
or other liquid coolants may results in electrocution or shock.
7) 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
workpiece, 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 rm 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.

8) Additional safety instructions for grinding and cutting-o
operations
Additional Safety Warnings Specic for Abrasive Cutting-O
Operations:
a) Use only wheel types that are recommended for your power tool
and the specic guard designed for the selected wheel. Wheels
for which the power tool was not designed cannot be adequately
guarded and are unsafe.
b) The guard must be securely attached to the power tool and
positioned for maximum safety, so the least amount of wheel is
exposed towards the operator. The guard helps to protect operator
from broken wheel fragments and accidental contact with wheel.
c) Wheels must be used only for recommended applications. For
example: do not grind with the side of cut-o wheel. Abrasive
cut-off wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
d) Always use undamaged wheel anges that are of correct size
and shape for your selected wheel. Proper wheel anges support
the wheel thus reducing the possibility of wheel breakage. Flanges
for cut-off wheels may be different from grinding wheel anges.
e) Do not use worn down wheels from larger power tools. Wheel
intended for larger power tool is not suitable for the higher speed of a
smaller tool and may burst.
9) Additional safety instructions for cutting-o operations
Additional Safety Warnings Specic for Abrasive Cutting-O
Operations (6145 only):
a) Do not “jam” the cut-o wheel or apply excessive pressure. Do
not attempt to make an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind the rotating
wheel. When the wheel, at the point of operation, is moving away
from your body, the possible kickback may propel the spinning wheel
and the power tool directly at you.
c) When wheel is binding or when interrupting a cut for any reason,
switch o the power tool and hold the power tool motionless
until the wheel comes to a complete stop. Never attempt to
remove the cut-o wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
EN
10 DialSpeed
TM
d) Do not restart the cutting operation in the workpiece. Let the
wheel reach full speed and carefully reenter the cut. The wheel
may bind, walk up or kickback if the power tool is restarted in the
workpiece.
e) Support panels or any oversized workpiece to minimize the
risk of wheel pinching and kickback. Large workpieces tend to
sag under their own weight. Supports must be placed under the
workpiece near the ne of cut and near the edge of the workpiece on
both sides of the wheel.
f) Use extra caution when making a “pocket cut” into existing
walls or other blind areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can cause kickback.
10) Additional safety instructions for polishing operations (Model
6145 only)
Safety Warning Specic for Polishing Operations (Model 6145 only):
a) Do not allow any loose parts or its attachment strings to spin
freely. Tuck away or trim any loose attachment strings. Loose
and spinning attachment strings can entangle your ngers or snag on
the workpiece.
11) Additional safety instructions for wire brushing operation (Model
6145 only)
Safety Warnings Specic for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even during
ordinary operation. Do not overstress the wires by applying
excessive load to the brush. The wire bristles can easily penetrate
light clothing and/or skin.
b) If the use of a guard is recommend for wire brushing, do not
allow any interference of the wire wheel or brush with the guard.
Wire wheel or brush may expand in diameter due to work load and
centrifugal forces.
EN

12) Addition:
a) Recommended diameter of accessories for the tool.
Flap wheel: Maximum 1- ½” (Model 6145 only)
Brushes: Maximum 3” (Model 6145 only)
b) Storage and handling of recommended accessories
Keep your power tool and accessories in a low humidity and
ambiant temperature at all time. This will prevent premature
breakage of your tool.
