SAFETY INSTRUCTIONS

1.1 GENERAL SAFETY INSTRUCTIONS

Read these OPERATING INSTRUCTIONS.
Make sure you have understood them before operating the machine for the first time.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to the power tool run off the electrical network (with a power cord) or to a battery run power tool (cordless).
Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool.

Work area
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
d) Never leave the power tool unattended. Leave the machine only when the tool is completely in neutral.
Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) 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.
e) 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.
f) 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.
Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust related hazards.
h) Do not allow the familiarity with the frequent use of tools to become complacent and ignore the principles of tool safety. Negligence can cause serious injury in a split second.
Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
h) Keep the handles dry, clean and free of oil and grease. The sliding handles do not allow safe handling and control of the tool in unexpected situations. Power tools with the switch on invite these situations.
Service
a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
b) Use only original parts for repair and maintenance. The use of incompatible accessories and parts can cause electric shock and other injuries.

USES

ORBITAL SANDING MACHINE: A single-handed sander for dry surface finishing. Equipped with forced suctioning of sanding dust.
To obtain a good quality finish, slide the machine over the surface to be worked in repetitive elliptical movements to avoid the formation of grooves on the sanded surface.
To achieve the desired finish, the surface should be sanded several times using a finer grain of abrasive each time. With the delta base 8445198 included with the machine, even difficult to reach inside corners and slatted shutter can easily be sanded.
The electronic speed adjustment allows you to work at the ideal speed for each abrasive and surface type. This is particularly useful for sanding heat- sensitive materials which require lower sanding speeds.
ROTARYORBITAL SANDER: The single-handed rotaryorbital sander combines two types of movement, one rotational and the other orbital, enabling it to perform planing and finish work very quickly. The smooth, sanded, groove-free surfaces produced make it ideal for delicate jobs and varnished wood. Equippedwith forced suctioning of sanding dust. The sander LRB384 is factory equipped with a velcro base plate 8445498, which enables it to be converted into a rotaryorbital sander.
Equipped with electronic speed adjustment devices which allow you to work at the ideal speed for each surface and abrasive type. This is particularly useful for sanding heat-sensitive materials which require lower sanding speeds.

NOISE LEVEL AND VIBRATIONS

The noise and vibration levels of this device have been measured in accordance with European standard EN 60745-2-4 and EN 60745-1 and serve as a basis for comparison with other machines with similar applications.
The indicated vibration level has been determined for the device’s main applications and may be used as an initial value for evaluating the risk presented by exposure to vibrations. However, vibrations may reach levels that are quite different from the declared value under other application conditions, with other tools or with insufficient maintenance of the electrical device or its accessories, reaching a much higher value as a result of the work cycle or the manner in which the electrical device is used.
Therefore, it is necessary to establish safety measures to protect the user from the effects of vibrations, such as maintaining both the device and its tools in perfect condition and organising the duration of work cycles (such as operating times when the machine is subjected to loads, and operating times when working with no-load, in effect, not in use, as reducing the latter may have a considerable effect upon the overall exposure value).
