1. SAFETYi
1.1. ELECTRICAL SAFETY
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.
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.
1.1.1. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
1.1.2. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
1.1.3. IMPORTANT: Ensure that the voltage rating on the appliance suits the power supply to be used and that the plug is tted with the
correct fuse - see fuse rating in these instructions.
8DO NOT pull or carry the appliance by the power cable.
8DO NOT pull the plug from the socket by the cable. Remove the plug from the socket by maintaining a rm grip on the plug.
8DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or replaced immediately by a
qualied electrician.
1.1.4. This product is tted with a BS1363A 3 pin plug.
If the cable or plug is damaged during use, switch the electricity supply and remove from use.
Replace a damaged plug with a BS1363A 3 pin plug. If in doubt contact a qualied electrician.
Class II products are wired with live (brown) and neutral (blue) only are marked with the
Class II symbol;
A) Connect the BROWN live wire to the live terminal ‘L’.
B) Connect the BLUE neutral wire to the neutral terminal ‘N’.
C) After wiring, check that there are no bare wires and ensure that all wires have been correctly connected.
Ensure that the cable outer sheath extends inside the cable restraint and that the restraint is tight.
DO NOT connect either wire to the earth terminal.
Sealey recommend that repairs are carried out by a qualied electrician.
9Power tool plugs must match the outlet.
8 Never modify the plug in any way. Do not use any adaptor plugs with earthed (grounded) power tools. Unmodied 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.
8DO NOT expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
8DO NOT abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from the 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. If operating a
power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk
of electric shock.

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): 3.221m/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 HSC website
www.hse.gov.uk - Hand-Arm Vibration at Work.
The declared vibration total value(s) and the declared noise emission value(s) have been measured in accordance with a standard test
method and may be used for comparing one tool with another. The declared vibration total values and the declared noise emission
values may also be used in a preliminary assessment of exposure.
The vibration and noise emissions during actual use of the power tool can differ from the declared values depending on the ways in which
the tool is used, especially what kind of work-piece is processed. The need to identify safety measures to protect the operator that are
based on an estimation of exposure in the actual condition of use.
