WARNING! It is the user’s responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and all electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical products. You may obtain an RCD by contacting your local Sealey Stockist.
If the product is used in the course of business duties, it must be maintained in a safe condition and routinely PAT (Portable Appliance Test) tested.
Electrical safety information, it is important that the following information is read and understood.

Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
Important: Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is ﬁtted with the correct fuse – see fuse rating in these instructions.
- DO NOT pull or carry the appliance by the power cable.
- DO NOT pull the plug from the socket by the cable. Remove the plug from the socket by maintaining a ﬁrm grip on the plug.
- DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or replaced immediately by a qualiﬁed electrician.

GENERAL SAFETY

Disconnect the hammer drill from the mains power before changing accessories, servicing or performing any maintenance.
Maintain the hammer drill in good condition.
Check moving parts and alignment and keep drill bits in good, sharp condition. If necessary use an authorised service agent.
Replace or repair damaged parts. Use recommended parts only. Unauthorized parts may be dangerous and will invalidate the warranty.
DO NOT use the hammer drill if the on/off switch does not work. Have it repaired by an authorised service agent.
Wear approved safety eye protection with side shields, ear defenders, safety shoes and gloves.
Wear ear defenders when impact drilling. Exposure to noise can cause hearing loss.
Remove ill fitting clothing. Remove ties, watches, rings, other loose jewellery and contain long hair.
Use the hammer drill in an adequate working area for its function, keep work area clean, tidy and free from unrelated materials, ensure adequate lighting.
Prevent body contact with grounded surfaces to avoid electric shock i.e. pipes, radiators, ranges, refrigerators etc.
Evaluate your working area before using the hammer drill i.e. ceiling, floors and enclosures may contain hidden electrical wires or water piping.
Maintain correct balance and footing.
DO NOT over-reach and ensure that the floor is not slippery and wear non skid safety shoes.
WARNING! If working at height take adequate safety precautions to prevent injury from falling.
DO NOT operate the hammer drill when you are tired or under the influence of alcohol, drugs or intoxicating medication.
WARNING! The auxiliary handle grip must always be attached for use. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
WARNING! Remove the chuck key before turning the hammer drill on.
DO NOT attempt to operate this hammer drill with one hand.
Keep children and unauthorized persons away from the working area.
DO NOT hold unsecured work in your hand.
Avoid unintentional starting and ensure the lock on button is disengaged before use.
DO NOT force the hammer drill to achieve a task it was not designed to perform.
DO NOT operate the hammer drill in explosive atmospheres or where there are flammable liquids, gasses or dust.
DO NOT carry the hammer drill with your finger on the power switch, or leave the hammer drill running whilst unattended.
DO NOT abuse the power cord. Never use the cord for carrying, pulling or unplugging the hammer drill.
Keep the power cord away from heat, oil, sharp edges or moving parts.
DO NOT operate the hammer drill if any parts are missing or the hammer drill is damaged as this may cause failure and/or possible personal injury.
Limit the exposure time by taking frequent rest periods. Vibration caused by hammer action may be harmful to your hands and arms.
When operating the hammer drill outdoors use an extension cable that is clearly marked for outdoor use.
Work only in daylight or good artificial light.
Keep handles and grasping surfaces dry, clean and free from oil and grease.
DO NOT allow the hammer drill to get wet.
DO NOT use in damp or wet locations.
DO NOT use in the rain or if there is a risk of lightning.
WARNING! If working in a damp location is unavoidable a residual current device (RCD) MUST be used.
DO NOT allow familiarity gained from frequent use of the hammer drill to let you become complacent and begin to ignore tool safety principles.
When not in use, switch the hammer drill off, remove plug from power supply, clean the hammer drill and store in safe, dry, childproof location.

USING LONG DRILL BIT SAFETY

DO NOT operate at a higher speed than the maximum speed rating of the drill bit.
Always start drilling at low speed and with the drill bit tip in contact with the workpiece.
Apply pressure only in direct line with the drill bit.
DO NOT apply excessive pressure.
WARNING! The warnings, cautions and instructions in this manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be applied by the operator.

WARNING! – Risk of Hand Arm Vibration Injury.

This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately. This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC. This tool is to be operated in accordance with these instructions.

Measured vibration emission value (a): . . . . . . . . . 16.33m/s²
Uncertainty value (k):. . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5m/s²

Please note that the application of the tool to a sole specialist task may produce a different average vibration emission. We recommend that a specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for each tool. NB: Stated Vibration Emission values are type-test values and are intended to be typical.
Whilst in use, the actual value will vary considerably from and depend on many factors.
Such factors include; the operator, the task and the inserted tool or consumable.
NB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration Syndrome.
Health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures
can be modified accordingly.
Personal protective equipment.
We are not aware of any personal protective equipment (PPE) that provides protection against vibration injury that may result from the uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain warm and dry and maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please refer to the Correct Use and Maintenance section in these instructions. Guidance relating to the management of hand arm vibration can be found on the HSE website www.hse.gov.uk – Hand-Arm Vibration at Work.
