1 Introduction and general information
Important! Operating instructions cannot
prevent misuse in every case!
1.1 Information on the operating instructions
These operating instructions are part of the technical documentation of the machine and comply with the
Machinery Directive.
The machine has been designed and built according to the careful selection of the harmonising standards to
be observed as well as other technical specifications.
The operating instructions are intended to describe the operation and handling of the EFA circular saw and
provide the necessary safety instructions.
These operating instructions are intended for the machine operator and contain the details of the intended use
and important information:
for safe handling of the machine,
for maintenance,
for cleaning.
If the instructions are followed, the EFA circular saw will be operated safely, properly and economically and its
operational capability will be maintained.
Observance of these instructions helps to avoid dangers, minimise repair costs and downtimes, and increase
the reliability and service life of the machine.
A prerequisite for safe handling and trouble-free operation of the machine is observance of the following:
the operating instructions,
the company directives (safety signs and danger warnings),
the legal provisions on occupational safety,
the applicable laws and regulations.
These operating instructions must always be kept accessible at the machine for all work to be carried out.
Note! If the existing operating instructions have been damaged or lost, you can request a
replacement by stating: machine designation, part number, serial number and year of
production, see section 3.2 Nameplate.
If you have any questions, or if you cannot solve a problem with the help of these operating instructions,
please contact our Service department.

Do not use materials harmful to health.
If, contrary to the intended use, materials harmful to health are to be processed then Schmid & Wezel GmbH
must be informed in writing about the planned use and the protective measures taken by the
customer/operating company.
The customer/operating company is solely responsible for suitable protective measures (e.g. extraction
devices, respiratory protection, protective suits, etc.) and company directives.

Warnings and symbols used in the operating instructions and documentation are intended to help you to
recognise and assess the dangers more easily.
Symbol
Meaning
Warning: Dangerous electrical voltage!
Touching live parts can result in immediate death. Covers or cabinets marked with this sign are only
allowed to be opened by qualified electricians after the machine has been switched off.
Warning: Sharp cutting tool!
Contact with the running cutting tool will lead to extremely severe cutting injuries involving permanent or
even fatal injury. Ensure that a sufficient safety distance is maintained. Contact with the stationary cutting
tool could lead to severe cutting injuries involving permanent injury. Wear safety gloves. Ensure that a
safety distance is maintained.
Warning: Hand injuries!
There is a danger of hands being pinched, pulled in or otherwise injured. Keep your hands away from
places that bear this warning sign!
Warning: Noise with high sound pressure level!
If the sound pressure level at the workplace is above 85 dB(A). Remaining for a relatively long period can
cause permanent hearing damage. Only enter the area if wearing the correct hearing protection.
Warning of hot surface!
It is not always possible to notice the presence of hot machine parts, containers or materials, as well as
hot liquids. If such a safety sign is affixed to a component, care must be taken. Do not touch hot surfaces
without protective gloves.

loads; bumping into obstacles also represents a danger. A suitable protective helmet must always be
worn on the head when in the indicated area.
Wear protective goggles!
Eye injuries (loss of vision) possible when working due to flying solid objects.
Wear hearing protection!
If the continuous sound pressure level of the machine/system is above 85 dB(A), hearing protection must

2.3 Conduct at the workplace
The workplaces must be designed in such a way that each employee has at least 1.5 m² of freedom of
movement. Ensure proper lighting of the workplace (at least 500 lux).
No other workplace should protrude into this area, otherwise there is an injury hazard due to the actions
carried out with circular saw.
The floor must minimise the danger of slipping on wet, greasy or dirty surfaces.
The workplace must comply with local hygiene and workplace regulations.
Keep your workplace tidy and in good working condition. A cluttered or messy workplace can lead to
accidents.
Take environmental influences into account.
Keep other persons away from your workplace. Focus on the job in hand when working.
Do not use the EFA circular saw when you are tired and/or unfocused.
Store the circular saw in a safe manner. Store unused devices in a dry place.
Avoid wearing loosely fitting items of clothing and jewellery that can be caught by moving parts. Wear
sturdy shoes during your work. Always wear a hairnet!
Ensure that your workplace has a correct, ergonomic set-up and make sure that you are standing
securely.
Only use original EFA saw blades. Follow the instructions listed under Saw blade change. See also
section 7.1 Saw blade change.
Do not leave any tool keys connected. Check that all keys have been removed before switching on.
Look after your tools with care. Use only sharp and undamaged saw blades so that you can work better
and more safely.
Only use genuine EFA accessories/spare parts.
Never drill into the motor housing. Use adhesive labels to identify the device.
Changes and modifications to the machine are not permitted and, if any such changes are made, S&W's
guarantee and liability shall be invalidated.
The use of other equipment, accessories or spare parts can endanger you and other persons.
Non-compliance will void the warranty.
