USER MANUAL H 90SC HITACHI

Read through carefully and understand these instructions before use.

Read all safety warnings and all instructions.

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

Save all warnings and instructions for future reference.

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

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.
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 influence 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 finger 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. 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, 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.

PRECAUTION

Keep children and infirm persons away.

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

APPLICATIONS

This Demolition Hammer should be applied to demolishing concrete, chiseling off concrete, grooving, bar cutting installation of piping and wiring, sanitary facility installation, machinery installation, water supply and drainage work, interior jobs, harbor facilities and other civil engineering works.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate of this Demolition Hammer.

1. 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, this Demolition Hammer will start operating immediately, which could cause a serious accident.

1. Extension cord

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

1. Mounting an accessory, such as a bull point, a cutter, etc.

(1) With the retainer directed backward, insert the accessory shank portion into the hole on the front cover. (Fig. 1)

(2) Swing the retainer back into place so that it engages the accessory shank portion and prevents the accessory, such as a bull point, a cutter, etc. from coming all the way out of front cover. (Fig. 2)
5. Always hold the body handle and side handle of this Demolition Hammer firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation.

OPERATION

1. Pull the trigger switch after applying the tip of the bit to the crushing position.
2. Operate this Demolition Hammer by utilizing its empty weight. The performance will not be better even if it is pressed or thrust forcibly against the work surface. Hold this Demolition Hammer with a force just sufficient to counteract the reaction.

This Demolition Hammer is equipped with a spring cushion on the handle so that chipping vibration is not conveyed to the operator.
Operate this Demolition Hammer without forcing the handle too strongly.

CAUTION

Sometimes the power tool does not begin the striking stroke even when the motor rotates because the oil has become thick.

If the power tool is used at low temperatures or if it is used after a long idle time, this Demolition Hammer should be kept running in for about five minutes in order to warm it up.

HOW TO REPLACE GREASE

This Demolition Hammer is of full air-tight construction to protect against dust and to prevent lubricant leakage. Therefore, this Demolition Hammer can be used without lubrication for long periods. Replace the grease as described below.

Grease Replacement Period

After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest authorized Service Center.

MAINTENANCE AND INSPECTION

CAUTION:

Be sure to swith OFF and disconnect the attachment plug from the receptacle to avoid a serious accident.

1. Inspecting this Demolition Hammer

Since use of a dull accessory, such as a bull point, a cutter, etc. will degrade efficiency and cause possible motor malfunction, sharpen or replace with a new one as soon as abrasion is noted.

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 retainer (Fig. 1, Fig. 2)

The retainer may become loose due to excessive use. Always, pay attention to its proper functioning to securely hold the accessory shank portion. If any wear and tear is found, bring this Demolition Hammer to an authorized service center for maintenance service.

4. 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.

5. Inspecting the carbon brushes (Fig. 3)

The motor employs carbon brushes which are consumable parts. When they become worn to or near "wear limit", it results in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Nos. shown in the Fig.3. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

6. Replacement procedure

Loosen the screw (Hexagon socket hd. bolt M4 × 10) of the cap cover, then remove the cap cover. (Fig. 4) After removing the brush cap, the carbon brush can be removed.

After replacing the carbon brush, tighten the brush cap, then mount the cap cover securely.
