GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, ﬁ re and/or serious injury.

Save all wa rnings and ins tructions f or future ref erence.

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

1) Work ar ea s afe ty 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 ﬂ 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.

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 p ower tool whil e you are tired o r 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 h at, or hear ing pro tection u sed 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.

Carr ying 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 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.

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.

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.

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 po wer tool misuse and/or inc orrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

a) Maintain a ﬁ 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.

SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING-OFF OPERATIONS

a) Use only wheel types that are recommended for

your power tool and the speciﬁ c guard designed for the selected wheel.

Wheels for which the power tool was not designed

cannot be adequately guarded and are unsafe.

English

b) The grinding surface of centre depressed wheels

must be mounted below the plane of the guard lip.

An improperly mounted wheel that projects through the

plane of the guard lip cannot be adequately protected.

The

guard must be securely attached to the power tool and positioned for maximum safety, so the least a

mount of wheel is exposed towards the

operator.

The guard helps to protect the operator from broken

wheel fragments, accidental contact with wheel and sparks that could ignite clothing.

d) Wheels must be used only for recommended

applications. For example: do not grind with the side of cut-oﬀ wheel.

Abrasive cut-oﬀ wheels are intended for peripheral

grinding, side forces applied to these wheels may cause them to shatter.

e) Always use undamaged wheel ﬂ anges that are of

correct size and shape for your selected wheel.

Proper wheel ﬂ anges support the wheel thus reducing

the possibility of wheel breakage. Flanges for cut-oﬀ wheels may be diﬀ erent from grinding wheel ﬂ anges.

f) 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.

ADDITIONAL SAFETY WARNINGS SPECIFIC FOR ABRASIVE CUTTING-OFF OPERATIONS

a) Do not “jam” the cut-oﬀ 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 oﬀ the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cutoﬀ 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.

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 line 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.

PRECAUTIONS ON USING DISC GRINDER

1. Never operate these power tools without Wheel Guards.

2. Check that speed marked on the wheel is equal to or greater than the rated speed of the grinder.

Use only depressed center wheels rated at 80 m/s or

more.

3. Ensure that the wheel dimensions are compatible with the grinder and that the wheel ﬁ ts the spindle.

4. Abrasive wheels shall be stored and handled with care in accordance with manufacturer’s instructions.

5. Inspect the depressed center wheel before use, do not use chipped, cracked or otherwise defective products.

6. Always hold the body handle and side handle of the power tool ﬁ rmly. Otherwise the counterforce produced may result in inac curate and even dangerous opera tion.

7. Do not use cutting-oﬀ wheels for side grinding.

8. Do not use of separate reducing bushings or adapters to adapt large hole abrasive wheels.

9. The wheel continues to rotate after the tool is switched oﬀ .

a cutting torch.

○ Grinding of synthetic resins, slate, brick, marble, etc. ○ Cutting of synthetic concrete, stone, brick, marble and

similar materials.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements speciﬁ ed on the product nameplate.

2. Power switch

Ensure that the power switch is in the OFF position. If

the plug is connected to a receptacle while the power switch is in the ON position, the power tool will star t operating immediately, which could cause a serious accident.

3. Extension cord

When the work area is removed from the power source,

use an extension cord of suﬃ cient thickness and rated capaci ty. The extension cord sho uld be kept as shor t as practicable.

4. Fitting and adjusting the wheel guard

The wheel guard is a protective device to prevent injury

should the depressed center wheel shatter during operation. Ensure that the guard is properly ﬁ tted and

fastened before commencing grinding operation. [Installing and adjusting the wheel guard] ○ Open the lever and insert the locating pin of wheel

guard, bringing it into line with the across ﬂ ats of

packing ground. ○ Then, turn the wheel guard to a desired position (for

use). ○ Close the lever and ﬁ x it. If and when required, carry out

adjustments by tightening or loosening the screw. ○ If the lever does not move smoothly, apply some

lubricating oil to the sliding section between the set

piece and the lever. ○ Fasten the wheel guard at the position where the across

ﬂ ats of the wheel guard positioning pin and packing

ground are aligned (the position where the wheel guard

is inserted), but do not use it.

5. Ensure that the depressed center wheel to be utilized is

the correct type and free of cracks or surface defects.

Also ensure that the depressed center wheel is properly

mounted and the wheel nut is securely tightened. Refer

to the section on “Assembling and Disassembling the

Depressed Center Wheel”.

6. Conducting a trial run

Ensure that the abrasive products is correctly mounted

Conﬁ rm that the spindle lock is disengaged by pushing

push button two or three times before switching the power tool on (See Fig. 1).

8. Fixing the side handle

Screw the side handle into the gear cover.

PRACTICAL GRINDER APPLICATION

1. Pressure

To prolong the life of the machine and ensure a ﬁ rst

class ﬁ nish, it is important that the machine should not be overloaded by applying too much pressure. In most appli cations, the we ight of the mach ine alone is su ﬃ cient for eﬀ ective grinding. Too much pressure will result in reduced rotational speed, inferior surface ﬁ nish, and overloading which could reduce the life of the machine.

2. Grinding angle

Do not apply the entire surface of the depressed center

wheel to the material to be ground. As shown in Fig. 3, the machine should be held at an angle of 15° – 30° so that the external edge of the depressed center wheel contacts the material at an optimum angle.

3. To prevent a new depressed center wheel from digging

into the workpiece, initial grinding should be performed by drawing the grinder across the workpiece toward the operator (Fig. 3 direction B). Once the leading edge of the depressed center wheel is properly abraded, grinding may be conducted in either direction.

4. Switch operation

Switch ON: Push the locking button forward and then

* For c ontinuous use, press th e switch lever.

Switch OFF: Press and release the switch lever.

5. Precautions immediately after ﬁ nishing operation

Af ter switching oﬀ the machine, do not put it down until

the depressed center wheel has come to a complete stop. Apar t from avoiding serious accidents, this precaution will reduce the amount of dust and swarf sucked into the machine.

CAUTION

○ Check that the work piece is properly supported. ○ Ensure that ventilation openings are kept clear when

working in dust y conditions.

If it should become necessary to clear dust, ﬁ rst

disconnect the tool from the mains supply (use nonmetallic objects) and avoid damaging internal par ts.

○ Ensure that sparks resulting from use do not create

a hazard e.g. do not hit persons, or ignite ﬂ ammable

substances. ○ Always use eye and ear protection. Other personal protective equipment such as dust

mask, gloves, helmet and apron should be worn when

necessary. If in doubt, wear the protective equipment. ○ When the machine is not use, the power source should

be disconnected.

press the switch lever.

The switch lever is locked by pushing the locking button forward once again. (*Subject to change depending on area.)

ASSEMBLING AND DISASSEMBLING THE DEPRESSED CENTER WHEEL

CAUTION

Be sure to switch OFF and disconnect the attachment

plug from the receptacle to avoid a serious accident.

1. Assembling (Fig. 1)

(1) Turn the machine upside down so that the spindle is

facing upward.

English

(2) Mount the wheel washer onto the spindle. (3) Fit the protruding part of the depressed center wheel or

diamond wheel onto the wheel washer. (4) Screw the wheel nut onto the spindle. (For diamond wheel assembling, use the wheel nut with

the convex side against the diamond wheel.) (5) Insert the push button to prevent rotation of the spindle,

and tighten the wheel nut with the accessory wrench,

as shown in Fig.1.

2. Disassembling

Follow the above procedures in reverse.

CAUTION

○ Comﬁ rm that the depressed center wheel is mounted

ﬁ rmly.

○ Conﬁ rm that the push button is disengaged by pushing

push button two or three times before switching the

power tool on.

MAINTENANCE AND INSPECTION

1. Inspecting the depressed center wheel

Ensure that the depressed center wheel is free of

cracks and surface defects.

2. 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.

3. Inspecting the carbon brushes (Fig. 4)

The motor employs carbon brushes which are

consumable parts. When they become worn to or near the “wear limit”, it

could re sult in motor trouble. Whe n an auto-stop c arbon

brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new

ones which have the same carbon brush numbers

shown in the ﬁ gure. In addition, always keep carbon

brushes clean and ensure that they slide freely within

the brush holders.

4. Replacing carbon brushes (Fig. 5)

<Disassembly> (1) Loosen the D4 tapping screw retaining the brush cover

and remove the brush cover. (2) Use the a uxiliar y hexagonal w rench or sm all screwdr iver

to pull up the edge of the spring that is holding down the

carbon brush. Remove the edge of the spring toward

the outside of the brush holder. (3) Remove the end of the pig-tail on the carbon br ush from

the terminal section of brush holder and then remove

the carbon brush form the brush holder. <Assembly> (1) Insert the end of the pig-tail of the carbon brush in the

terminal section of brush holder. (2) Insert the carbon brush in the brush holder. (3) Use the a uxiliar y hexagonal w rench or sm all screwdr iver
