Additional Safety Instructions for Rotary Hammers

  •  Wear ear protectors. 

Exposure to noise can cause hearing loss.

  •  Use auxiliary handles supplied with the tool.

 Loss of control can cause 

personal injury.

 • 

Hold power tools by insulated gripping surfaces when performing an 

operation where the cutting tool may contact hidden wiring or its own cord. 

Contact with a “live” wire will make exposed metal parts of the tool “live” and 

shock the operator. 

  •  Use clamps or other practical way to secure and support the workpiece to a 

stable platform. 

Holding the work by hand or against your body is unstable and 

may lead to loss of control.

  •  Wear safety goggles or other eye protection.

 Hammering operations cause 

chips to fly. Flying particles can cause permanent eye damage. Wear a dust 

mask or respirator for applications that generate dust. Ear protection may be 

required for most applications.

  •  Keep a firm grip on the tool at all times. Do not attempt to operate this tool 

without holding it with both hands. 

It is recommended that the side handle 

be used at all times. Operating this tool with one hand will result in loss of 

control. Breaking through or encountering hard materials such as re-bar may be 

hazardous as well. Tighten the side handle securely before use.

  •  The hammer is only for light chiselling applications.
  •  The forward/reverse switch must be in the forward position when chiselling.
  •  Do not use this tool to mix or pump easily com busti ble or explosive fluids (ben-

zine, alcohol, etc.).

  •  Do not mix or stir inflammable liquids labelled accordingly.

  •  Do not operate this tool for long periods of time. 

Vibration caused by hammer 

action may be harmful to your hands and arms. Use gloves to provide extra 

cushion and limit exposure by taking frequent rest periods.

  •  Do not recondition bits yourself.

 Chisel reconditioning should be done by an 

authorized specialist. Improperly reconditioned chisels could cause injury.

  •  Wear gloves when operating tool or changing bits. 

Accessible metal parts on 

the tool and bits may get extremely hot during operation. Small bits of broken 

material may damage bare hands.

  •  Never lay the tool down until the bit has come to a complete stop. 

Moving bits 

could cause injury.

  •  Do not strike jammed bits with a hammer to dislodge them.

 Fragments of metal 

or material chips could dislodge and cause injury.

  •  Slightly worn chisels can be resharpened by grinding.
  •  Keep the power cord away from the rotating bit. Do not wrap the cord around 

any part of your body. 

An electric cord wrapped around a spinning bit may 

cause personal injury and loss of control.

 • 

Air vents often cover moving parts and should be avoided.

 Loose clothes, 

jewellery or long hair can be caught in moving parts.

•  Do not overheat the bit (discoloration) while grinding a new edge. 

Badly worn 

chisels require reforging. Do not reharden and temper the chisel.

WARNING: ALWAYS wear approved protective safety equipment complying with 

the following standards:

•  Eye protection: AS/NZS1337 Eye Protectors for Industrial Applications;
•  Hearing protection: AS/NZS1270 Acoustics – Hearing Protection;
•  Respiratory protection: AS/NZS1716 Respiratory Protective Devices.

WARNING: 

Some dust created by power sanding, sawing, grinding, drilling, and 

other construction activities contains chemicals known to cause cancer, birth defects 

or other reproductive harm. Some examples of these chemicals are:

•  lead from lead-based paints,
•  crystalline silica from bricks and cement and other masonry products, and 
•  arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of 

work. To reduce your exposure to these chemicals: work in a well ventilated area, and 

work with approved safety equipment, such as those dust masks that are specially 

designed to filter out microscopic particles.

  •

  Avoid prolonged contact with dust from power sanding, sawing, grinding, 

drilling, and other construction activities. Wear protective clothing and wash 

exposed areas with soap and water. 

Allowing dust to get into your mouth, eyes, 

or lay on the skin may promote absorption of harmful chemicals. 

WARNING: 

Use of this tool can generate and/or disburse dust, which may cause 

serious and permanent respiratory or other injury. Always use AS/NZS standards 

approved respiratory protection appropriate for the dust exposure. Direct particles 

away from face and body.
