working cycle.
• The hood must be positioned horizontally above the saw
blade during every working cycle.
• Always use the push-stick when cutting narrow
workpieces (less than 120 mm in width) lengthwise.
• Switch off the machine during troubleshooting or to
remove jammed pieces of wood. Disconnect power
supply plug!
• Wear close-fitting garments. Do not wear jewelry, rings or
wrist-watches.
• Check direction of motor and tool rotation (refer to
Electrical Connection).
• Machine safety equipment should not be detached or
disabled under any circumstances.
• The motor must be switched off during any conversion,
adjustment, measurement and cleaning work to the
machine. Disconnect the power supply plug and wait
until the rotating saw has come to a complete stop.
Proper Use
• This machine complies with the applicable EC machine
guideline.
• This machine has a work area located in front of the
machine to the left or right of the saw blade.
• To prevent accidents the work area and the area around
the machine must be clear of any foreign objects which
could interfere with machine operation.
• Workpieces should not contain any foreign objects such
as nails or screws.
• Prior to initial operation the machine must be connected
to a dust extractor by means of a flexible, non-flammable
suction hose.
• For use in closed spaces the machine must be connected
to a dust extractor. Use a ha 3200 or ha 2600 dust
extractor to extract wood shavings or sawdust. The flow
rate at the suction connection piece should be 20 m/s.
Partial vacuum 1200 Pa.
• The automatic switch on device is available as a special
accessory. Type ALV 2
230 V/50 Hz Type ALV 10 Art. No. 7910 4020
400 V/50 HzWhen the machine is switched on the dust
extractor switches on automatically after a 2 - 3 second
time delay. This prevents overstress to the house fuse.
After the machine has been switched off the dust
extractor continues to run for 3 - 4 seconds before
switching off automatically.This ensures that residual
dust is extracted in accordance with the hazardous
materials ordinance. This conserves electricity and
reduces noise. The dust extractor runs only when the
machine is in operation.For industrial work use the rg
4000 dust extractor.Do not switch off or remove dust
extractors when the machine is in operation.
• The panel sizing circular saw is designed for use in
processing wood or wood-like materials only. Use genuine
parts and accessories only. Select the correct saw blade
according to type of cut and type of wood (solid wood,
plywood or particle board) in accordance with EN 847-
1. Refer to the special accessories list.
• The manufacturer shall not be held liable for improper
use!!
 Additional Hazards
This machine is designed in accordance with state of the art
technology and accepted standards of technical safety. In
spite of this certain additional hazards may occur during
operation of this machine.
• Risk of injury to fingers and hands from rotating saw or
Art. No. 7910 4010
workpiece if saw or workpiece is routed improperly.
• Risk of injury from rotating saw resulting from improper
mounting or guide control or from operation without end
stop.
• Health risks due to excessive noise. Permissable noise
levels are exceeded during operation of the machine.
Always wear ear protection.
• Risk of injuries from defective saw blade. Check blade
condition regularly.
• Electrical hazards if improper connection cables are
used.
• In spite of all safety precautions instituted additional
unforseeable hazards may occur.
• To minimize the risk of additional hazards follow all
safety instructions, instructions for proper use, and
operating instructions carefully.
Noise Characteristics
Measurement Requirements in Accordance with Draft Pre-
Norm EN 1870-1: 1995-07
sound power level in dB
idle L = 97,5 dB(A)operation L
WA
sound pressure level in work areain dB
idle LpAeq = 86,7 dB(A)operation LpAeg = 87,1 dB(A)
A measurement error K = 4 dB applies for the emission
values listed.
The values listed are emission measurements and therefore
do not necessarily represent reliable work values. Though a
correlation does exist between emission levels and
immision levels it is not possible to determine from this
with reliability whether additional safety precautions are
required or not. Factors which may influence existing work
area immission levels are length of exposure, individual
characteristics of the work area, other noise emission
sources etc. (e.g. number of machines and other processes
in the vicinity). Permissable work area noise levels may
vary from country to country. The information provided
here should however enable the user to better estimate
hazards and risks.
Dust Emission Data
The dust emission levels measured in accordance with the
Guidelines for Testing Dust Emission (Concentration
Parameters) of Wood Processing Machines issued by the
Committee of Wood Experts are below 2 mg/m
compliance with the TRK air quality levels for wood dust
which apply in the Federal Republic of Germany is ensured
if the machine is connected to a proper operative suction
unit with an air speed of not less than 20 m/s.
Assembly
Always disconnect the power supply plug before doing any
assembly or conversion work.
For packing reasons your panel sizing circular saw is only
partly assembled at delivery.
