SPECIFICATIONS

• Due to our continuing program of research and development, the specifications herein are subject to change without notice.
• Note: Specifications may differ from country to country.
• Weight according to EPTA-Procedure 01/2003

Intended use
The tool is intended for chiselling work in concrete, brick, stone and asphalt as well as for driving and compacting with appropriate accessories.

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.
Noise
The typical A-weighted noise level determined accord-ing to EN60745:

• Model HM1213C
  • Sound pressure level (LpA) : 75 dB (A)
  • Sound power level (LWA) : 95 dB (A)
  • Uncertainty (K) : 2.53 dB (A)
• Model HM1203C
  • Sound pressure level (LpA) : 81 dB (A)
  • Sound power level (LWA) : 95 dB (A)
  • Uncertainty (K) : 2.1 dB (A)

NOTE: The declared noise emission value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
NOTE: The declared noise emission value(s) may also be used in a preliminary assessment of exposure.

WARNING: Wear ear protection.
WARNING: The noise emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
WARNING: Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

Vibration
The vibration total value (tri-axial vector sum) determined according to EN60745:

• Model HM1213C
  • Work mode : chiselling function with side handle
  • Vibration emission (ah,CHeq) : 8.0 m/s2
  • Uncertainty (K) : 1.5 m/s2
• Model HM1203C
  • Work mode : chiselling function with side handle
  • Vibration emission (ah,CHeq) : 16.5 m/s2
  • Uncertainty (K) : 1.5 m/s2

NOTE: The declared vibration total value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
NOTE: The declared vibration total value(s) may also be used in a preliminary assessment of exposure.

WARNING: The vibration emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
WARNING: Be sure to identify safety mea-sures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

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.

HAMMER SAFETY WARNINGS

1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
3. Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
4. Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sunglasses are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly padded gloves.
5. Be sure the bit is secured in place before operation.
6. Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation.
7. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult.
8. Always be sure you have a firm footing.
   Be sure no one is below when using the tool in high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool only when hand-held.
12. Do not point the tool at anyone in the area when operating. The bit could fly out and injure someone seriously.
13. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.
14. Do not operate the tool at no-load unnecessarily.
15. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

WARNING: DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product.
MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Switch action
Fig.1: 1. Switch lever
CAUTION:

• Before plugging in the tool, always check to see that the tool is switched off.
• Switch can be locked in “ON” position for ease of operator comfort during extended use. Apply caution when locking tool in “ON” position and maintain firm grasp on tool.

To start the tool, push the switch lever “ON (I)” on the left side of the tool. To stop the tool, push the switch lever “OFF (O)” on the right side of the tool.

Speed change
Fig.2: 1. Adjusting dial
The blows per minute can be adjusted just by turning the adjusting dial. This can be done even while the tool is running. The dial is marked 1 (lowest speed) to 5 (full speed).
Refer to the table below for the relationship between the number settings on the adjusting dial and the blows per minute.

CAUTION:

• The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work.

For Model HM1213C only
NOTE:

• Blows at no load per minute becomes smallerthan those on load in order to reduce vibration under no load, but this does not show trouble .
  Once operation starts with a bit against concrete, blows per minute increase and get to the numbers as shown in the table. When temperature is low and there is less fluidity in grease, the tool may not have this function even with the motor rotating.

Indicator lamp
