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.

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.

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.

APPLICATIONS

Crushing concrete, chipping, digging, and squaring.

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.

PRIOR TO OPERATION

1. Power source

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

2. Grounding

This tool should be grounded while in use to protect the operator from electric shock. The tool is equipped with a three conductor cord and grounding type plug to fit the proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal.

3. 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, which could cause a serious accident.

4. 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.

5. Feeding oil (refer to the paragraph on oil feeding)

Prior to using the power tool, remove the oil gauge and do not fail the oil tank with the provided oil. (Although the oil tank is built in, it contains only a small volume of oil when shipped from the HiKOKI Works.)

6. Mounting a tool

NOTE

When handling bull point, cold chisel and other accessories, HiKOKI standard tools are recommended for better operation.

(1) Turn the stop lever in the arrow direction, insert the tool shank into the hexagon hole on the front cover.

(2) Replace the stop lever to grip the tool fi rmly.

NOTE

When removing the tool, follow the above procedures in reverse.

7. Set the side handle

When the M8 bolt is loosened with hexagon bar wrench, the side handle becomes freely movable. Set the side handle to a position conforming to the job, and then securely clamp the bolt.

HOW TO USE THE DEMOLITION HAMMER (Fig. 3)

1. Pull the trigger switch after applying the tip of the bit to the crushing position.

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.

OIL FEEDING

CAUTION

Prior to oil feeding, always disconnect the plug from the receptacle.

Since an oil chamber is built in this Demolition Hammer, it can be used for approximately 20 days without replenishing lubricating oil, assuming that the Hammer is used continuously 3 – 4 hours daily.

Feed oil into the oil tank as described below before using this Hammer. (see Fig. 4 and 5)

1. Just before no oil is visible in the oil gauge window when the power tool is held upright, feed oil without fail.

2. Before feeding oil, use the provided wrench to remove the oil gauge.

Be careful not to lose the rubber packing attached below the oil gauge.

1. Check the oil level once a day, confirming that oil is filled.

2. After feeding oil, securely clamp the oil gauge.

NOTE

As an optional accessory, oil for the HiKOKI Demolition Hammer (one liter) is sold separately. Use this oil when oil in the tank is depleted. Shell Oil Co. ROTELLA #40 (engine oil) can also be used. This oil is sold as Shell gasoline stations most anywhere.

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 cause motor malfunctioning and degraded efficiently, whet it or replace with a new one without delay when 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. 6)

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

The carbon brushes can be removed by removing the tail cover, and brush caps in that order at the interior.
