GENERAL SAFETY RULES

WARNING! Read all instructions

Failure to follow all instructions listed below may result in electric shock, ﬁ re 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 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 ﬂ ammable liquids, gases or dust.

Power tools create sparks which may ignite the dust

of 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.

Unmodiﬁ ed 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.

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 inﬂ uence 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 ﬁ nger 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 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 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

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 aﬀ ect 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 diﬀ erent from

intended could result in a hazardous situation.

5) Service a) Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement parts.

This will ensure that the safety of the power tool is

maintained.

PRECAUTION Keep children and inﬁ rm persons away. When not in use, tools should be stored out of reach of children and inﬁ rm persons.

PRACTICAL OPERATING PROCEDURES

CAUTION

Never apply water or grinding ﬂ uid when sanding. This

could result in electrical shock.

1. Switching the sander ON and OFF

By pulling the trigger and pushing the stopper, the

switch will remain ON even when the trigger is released, promoting continuous, eﬃ cient operation. By pulling the trigger again, the stopper is released and the switch is turned OFF.

CAUTION

Never turn the power switch ON when the sander is

contacting the surface to be sanded. This is necessary to preclude damage to the material. The same applies when switching the power OFF.

2. How to hold the orbital sander

While gripping the knob with one hand and the handle

with the other, lightly press the sander against the surface to be sanded so that the sanding paper uniformly contacts the surface, as shown in Fig. 6. DO NOT apply excessive pressure to the sander while sanding. Excessive-pressure may cause overload of the motor, reduced service life of the sanding paper, and lowered sanding or polishing eﬃ ciency.

3. How to move the orbital sander

For optimum operating eﬃ ciency, alternately move the

sander forward and backward at a constant speed and balance.

4. Changing the rotating Speed (model SV12V only)

SV12V has an electronic control system which can be

used to set the rotating speed between 4000 and 10000 revolutions per minute.

As shown in Fig. 7, dial position “1” is for minimum speed

and position “5” for maximum speed.

MOUNTING THE OPTIONAL ACCESSORIES

1. Mounting the magic pad.

Loosen the six screws. Remove the pad and attach the magic pad.

CAUTION

Replace the pad only. Use the other parts without

removing them.

2. Mounting the cleaner adapter (for models SV12V and SV12SD) (Fig. 8)

After mounting the dust collector hose onto the cleaner

adapter, mount the cleaner adapter onto the unit in the same way as mounting the dust bag.

MAINTENANCE AND INSPECTION

1. Empting and cleaning the Dust Bag (for models SV12V and SV12SD)

If the dust bag contains too much saw dust, dust

collection will be aﬀ ected. Empty the dust bag when it gets full.

Remove the dust bag, open the fastener, and dispose of

the contents.

2. Inspecting the sanding paper

Since use of worn-out sanding paper will degrade

eﬃ ciency and cause possible damage to the pad, replace the sanding paper as soon as excessive abrasion is noted.

3. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

4. Inspecting the carbon brushes (Fig. 10)

The motor employs carbon brushes which are

consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the ﬁ gure when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes

○ Disassembling (1) Loosen the two screws on the top cover, and remove the

top cover. (Fig. 11)

(2) Lift out the brush holder together with the carbon brush,

while being very careful not to forcibly pull the internal wires within the brush holder.

(3) Remove the carbon brush from the brush holder. ○ Reassembling (1) Insert the brush terminal into the brush holder. Turn the

brush terminal 90˚.

(2) While maintaining this brush terminal position as

explained in (1), insert the new carbon brush into the brush holder.

(3) While pressing the carbon brush against the outside wall

of the housing's bearing compartment, insert the brush holder into the housing's original position.

(4) Place the internal wire in the speciﬁ ed position. Be

very careful not to allow the internal wire to contact the armature or rotating parts of the motor. (Fig.12)

(5) Replace the top cover, while being careful to ensure it

does not pinch the internal wire, and secure it ﬁ rmly with the two screws.

CAUTION

Should the internal wire be pinched by the top cover

or come in contact with the armature or rotating parts of the motor, a serious danger of electric shock to the operator will be created. Exercise extreme caution in disassembling and reassembling the motor, following the above procedure exactly.

DO NOT attempt to disassemble any parts other than

those necessary to eﬀ ect replacement of the carbon brush.

6. Maintenance of the motor

The motor unit winding is the very “heart” of the power

tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
