1. Keep work area clean. Cluttered areas and benches

2. Consider work area environment. Do not expose

power tools to rain. Do not use power tools in damp or wet locations. Keep work area well lit. Do not use power tools where there is risk to cause fire or explosion.

3. Guard against electric shock. Avoid body contact

with earthed or grounded surfaces. (e.g. pipes, radiators, ranges, refrigerators).

4. Keep children away. Do not let visitors touch the

tool or extension cord. All visitors should be kept away from work area.

5. Store idle tools. When not in use, tools should

be stored in a dry, high or locked up place, out of reach of children.

6. Do not force the tool. It will do the job better and

safer at the rate for which it was intended.

11. Do not abuse the cord. Never carry the tool by

the cord or yank it to disconnect it from the receptacle. Keep the cord away from heat, oil and sharp edges.

12. Secure work. Use clamps or a vise to hold the

work. It is safer than using your hand and it frees both hands to operate tool.

13. Do not overreach. Keep proper footing and balance

14. Maintain tools with care. Keep cutting tools sharp

and clean for better and safer performance. Follow instructions for lubrication and changing accessories. Inspect tool cords periodically and if damaged, have it repaired by authorized service center. Inspect extension cords periodically and replace, if damaged. Keep handles dry, clean, and free from oil and grease.

15. Disconnect tools. When not in use, before servicing,

and when changing accessories such as blades, bits and cutters.

OPTIONAL ACCESSORIES (sold separately) 䡬 Asphalt Cutting 䡬 Groove Digging and Edging 䡬 Tamping 䡬 Scooping Work 䡬 Grease 500g (in a can) 30g (in a tube) Optional accessories are subject to change without notice. APPLICATIONS Demolishing concrete, chiseling off concrete, grooving, bar cutting. Application examples: Installation of piping and wiring, sanitary facility installation, machinery installation, water supply and drainage work, interior jobs, harbor facilities and other civil engineering works.

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

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, which could cause a serious accident.

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.

NOTE: For tools such as a bull point and a cold chisel, use only genuine HITACHI parts. (1) Clean, then smear the tool shank with grease or machine oil. (Fig.1) (2) Rotate the stop lever 180° in a clockwise direction while pulling it toward you. Next, insert the tool shank into the hexagonal hole on the frontcover. (Fig.1) (3) Clamp the tool by turning the stop lever by half a turn in the opposite direction. (Fig. 2)

HOW TO USE THE DEMOLITION HAMMER

1. Squeeze the trigger switch after applying the tip of

the bit to the crushing position. In some cases, it is necessary to punch the tip of the bit against the crushing position forcibly in order to begin the striking motion. This is not due to malfunction of the tool. It means that the safe guard mechanism against no-load striking is working.

2. Operate the tool by utilizing its empty weight. The

performance will not be better even if the tool is pressed or thrust forcibly against the work surface. Hold the tool with a force just sufficient to counteract the reaction. (Fig. 3) (1) Cutter Overall Length: 410 mm Width: 75 mm (1) Scoop Overall Length: 410 mm (2) Shank Overall Length: 250 mm (1) Cold Chisel Overall Length: 410 mm Outer diameter: 200 mm (1) Rammer5 English GREASE REPLACEMENT This machine is of full air-tight construction to protect against dust and to prevent lubricant leakage. Therefore, the machine 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 HITACHI 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 the tool

Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool 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. 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.

4. 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 result 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 Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes:

Loosen the screws (Hexagon socket hd. bolt M4×12) of the cap covers, then remove the cap covers (Fig. 5). After removing the brush caps, the carbon brushes can be removed. After replacing the carbon brushes, tighten the brush caps, then mount the cap covers securely.
