Product Information: H 65SB3 Demolition Hammer

The H 65SB3 Demolition Hammer is a power tool designed for heavy-duty demolition work. It comes with standard accessories such as a bull point and a case. The tool has insulated gripping surfaces to prevent electric shock if the cutting accessory comes in contact with hidden wiring or its own cord. It is a Class II tool that requires ear protectors to avoid hearing loss from exposure to noise.

The tool should be operated in a clean and well-lit work area, away from explosive atmospheres such as flammable liquids, gases, or dust. Children and bystanders should be kept away from the work area to avoid distractions that could cause the operator to lose
control of the tool. The power source used should conform to the power requirements specified on the product nameplate.

Before starting work, it is essential to confirm that electric cables or conduits are not buried inside the wall, floor, or ceiling where the tool will be used. The bit holder should be correctly set, and screw tightening should be confirmed at the start of work. When working at a highly elevated location, extra attention should be paid to avoid accidents.

The tool should be serviced by a qualified repair person using only identical replacement parts to maintain its safety. When not in use, it should be stored out of reach of children and infirm persons.

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, 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.

Work area safety

• Keep work area clean and well-lit.
  Cluttered or dark areas invite accidents.

• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
  Power tools create sparks that may ignite dust or fumes.

• Keep children and bystanders away while operating a power tool.
  Distractions can cause you to lose control.

Electrical safety

• 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.

• 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.

• Do not expose power tools to rain or wet conditions.
  Water entering a power tool will increase the risk of electric shock.

• 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.

• 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.

MAINTENANCE AND INSPECTION

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

1. Inspecting accessories
   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. 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 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 Numbers ⓑ shown in the Fig. 4. 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 M4×8) of the cap covers, then remove the cap covers (Fig. 4). 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.

CAUTION
In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
