GENERAL SAFETY RULES

WARNING! 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 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 flammable 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.

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 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 affect 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 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.

PRECAUTION

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

APPLICATIONS

䡬 Sanding metal surfaces. 䡬 Preliminary sanding of metal surfaces before painting,

rust removal, removing old paint before repainting. 䡬 Finishing woodwork, correcting projections of timbers

from joints or assemblies. 䡬 Preliminary sanding of wood surfaces before applying

paint.

5. Be careful those around one while operating.

6. Follow the procedures of these handling instructions on sanding disc replacement.

7. Never mount a depressed center wheel on this tool and attempt to use it as a disc grinder.

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified 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 start operating immediately, inviting serious accident.

3. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

CAUTION:

Damaged cord must be replaced or repaired.

4. Attaching sanding disc

For attachment/removal of the sanding disc, refer to “ATTACHMENT/REMOVAL OF SANDING DISC”. Many types of sanding discs are available; select one appropriate to the work.

5. Fixing the side handle

Screw the side handle into the housing.

6. Confirm the lock lever

Confirm that the lock lever is disengaged by pushing lock lever two or three times before switching the power tool on (See Fig. 2)

7. Install the air cover on the air vent on the side where

the side handle is attached to divert the cooling air flow of the motor during operation as much as possible. Hook tab of the air cover to the air vent and push in the tab when installing. Use a screwdriver etc. to pull as shown in Fig. 3 when removing.

PRACTICAL SANDER APPLICATIONS

1. Do not heavily push the sanding disc to the surface to

be ground. Grinding operation can be achieved with the weight of the machine alone, so maintain the sanding disc to an extent that it lightly touches the surface to be ground. When the sanding disc is pushed

heavily, its revolving speed drops, creating an unevenly finished surface and causing motor seizure from overload.

2. Rather than applying the entire disc surface to the metal surface to be gorund, use the sander by inclining it approximately 15° – 30° to grind with the disc peripheral portion. (Fig. 1)

3. Switching on the sander

The switch is of the quick-break trigger system. When the trigger is pulled, the switch turns on; and when it is released, the switch turns off. When it is desired to keep the power on for a prolonged period in continuous use, the stopper can be used to keep the switch on even after the trigger has been released. (First pull the trigger, and then press the stopper.) To turn the switch off, first pull the trigger again to disengage the stopper.

4. Precaution after use

Do not lay the sander down immediately after using on a place where there are many shavings, much dirt and dust until it has completely stopped revolving.

CAUTION

When the disc sander is not in use, the pwer source should be disconnected.

A: Item No. B: Code No. C: No. Used D: Remarks

Repair, modification and inspection of Hitachi Power Tools must be carried out by a Hitachi Authorized Service Center. This Parts List will be helpful if presented with the tool to the Hitachi Authorized Service Center when requesting repair or other maintenance. In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.

Hitachi Power Tools are constantly being improved and modified to incorporate the latest technological advancements. Accordingly, some parts (i.e. code numbers and/or design) may be changed without prior notice.

Due to HITACHI’s continuing program of research and development, the specifications herein are subject to change without prior notice.

MAINTENANCE AND INSPECTION

1. 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.

2. 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.

3. Inspecting the carbon brushes (Fig. 4)

The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush could result in motor trouble, replace the carbon brushes with new ones which have the same carbon brush No. shown in the figure when they become worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
