3.6 Machine Description
The bandsaws of the PANHANS BSB 400 - 900 series are modern and spacious bandsaws suitable for cutting
(cross-cutting and splitting) wood and similar materials. The tool is a toothed steel band to which the cutting
movement is transmitted by two band rollers.
After actuating the main switch, the drive motor drives the lower flywheel. All operating elements as well as the
emergency stop switch are easily accessible from the machine operator's workplace.
The machine operator transfers the cutting movement to the workpiece, either manually or by means of addi-
tional auxiliary or pushing devices. The adjustable guard reduces the risk of contact with the working tool.

3.7 About the BSB 400 - 900 Series
Bandsaw machines of the Panhans BSB 400 - 900 series are available in different versions. They basically differ
in their sizes and wheel diameters as well as in the possible cutting heights and cutting widths. This enables them
to be individually adapted to different areas of application.
A torsion-free double-chamber welded construction forms the basis for all functional elements. Both safety doors
are secured by safety switches and can only be opened after manual unlocking. The finely planed work table
made of grey cast iron is generously dimensioned. It allows safe, precise and economical working.
The material fence is particularly stable and equipped with a practical quick-clamping device. The precise APA 2
bandsaw guide ensures optimum cutting results.

4Safety
4.1 Basic Safety Instructions
Woodworking machines can be dangerous if used improperly. Therefore, observe the safety instructions listed
in this chapter and the accident prevention regulations of your employer's liability insurance association!
The manufacturer accepts no liability for damage and malfunctions resulting from failure
to observe these operating instructions.
4.1.1 Application Area and Intended Use
The bandsaws BSB 400 - 900 are designed exclusively for cutting (coping and splitting) ma-
terials for which the respective bandsaw blade used is suitable (e.g. wood or other materi-
als with the same physical and technical properties).
This machine is not suitable for working on metal or scrap wood - which could contain nails,
screws and other metal parts.
The machine may only be operated on a level, firm surface with a sufficiently high minimum
load corresponding to the weight of the machine (refer to section  5.2).
Other materials such as cork, rubber, hard plastics, bones, etc. can also be processed. Check whether the saw
blade used is suitable for cutting these materials. Cutting these materials may require special safety measures,
even if there is no obvious danger.
Any processing of other materials requires prior consultation with the manufacturer and his approval.
Improper use can lead to danger to persons and to a defect or damage to the machine.
Only lades recommended by the manufacturer are permitted.
The machine is not suitable for operation outdoors or in potentially explosive environments.
•Permissible ambient temperature: - 15 …+40° C
•Permissible humidity: 30 …90 %
Intended use also includes connecting the machine to an adequately dimensioned extraction system and observ-
ing the operating, maintenance and servicing conditions specified in the operating manual. Any other use is con-
sidered improper and is prohibited.
4.1.2 Modifications and Conversions to the Machine

Unauthorised conversions and modifications to the machine are strictly prohibited for safety
reasons. This will invalidate the CE declaration of conformity! The manufacturer is not liable
for any resulting damage. The risk for this is borne exclusively by the operator/user.
4.1.3 Connection to a Central Emergency Stop Switch
In workshops where the bandsaw is to be connected to a central emergency stop switch (e.g. school facilities), it
should be noted that bandsaw models with electric motor brake are not suitable for this purpose. If an emer-
gency release is triggered externally, the motor brake is no longer supplied with power. Therefore, the bandsaw
blade continues to run unbraked until it comes to a standstill.

4.1.4 Residual Risks
The machine is built according to the latest state of the art and the recognised safety rules. Nevertheless, the
use of the machine may cause danger to life and limb of the user or third parties or damage to the machine and
other equipment. Due to the construction of the machine, the following residual risks can occur even when used
as intended and despite compliance with all relevant safety regulations:
Reading and applying the operating manual is mandatory for the operating personnel.
Be alert to possible crushing hazards:
a) when transporting the machine by forklift truck →between forks & pallet / machine
b) when picking up the machine →between machine / pallet and floor
c) when lowering the machine →between machine and fixed equipment
Be alert to possible crushing hazards when lowering the machine (from the cargo pallet to the
floor) with a forklift truck or overhead crane.
Make sure that no objects fall from the forklift truck / crane.
Do not leave any objects / tools on the machine.
It is strictly prohibited to ride on the machine during a lifting operation (with the indoor crane or
forklift). There is a danger of falling!
Unauthorised persons are not allowed to enter the installation area of the machine
(responsibility of the operator).
Be aware of possible tripping and slipping hazards on the floor. Prevent possible hazards by keep-
ing the floor dry and clean and by using anti-slip floor coverings around the machine.
Be aware of the danger from falling objects such as workpieces, tools or similar. Therefore, wear
safety shoes, especially when transporting and setting down the machine.
Pay attention to the existing danger of being cut by the bandsaw blade. Never reach into the run-
ning bandsaw blade! Use pushing devices for short and thin workpieces. Wear protective gloves
when changing the saw blade.
Be aware of the danger of snow from chips and splinters and never remove them from the danger
area by hand. Use suitable aids, e.g. hand brushes.
Danger of cutting and drawing in! Do not clean the bandsaw blade or bandsaw roller with a brush
or scraper held in your hand while the machine is running.
Danger of cutting and drawing in! In case of a broken bandsaw blade or belt, wait until the machine
has come to a complete standstill and only then open the separating safety device.
Be aware of a possible danger of being drawn in by moving machine parts or tools. This can cause
pieces of clothing or hair to be caught. Always wear tight-fitting clothing and a hair net if necessary.
Generally avoid jewellery, loose clothing and untied long hair.
Danger from electric shock! There are hazards when working on the electrical system.
This work must only be carried out by qualified personnel!
Danger from electric shock! It is strictly forbidden to bypass safety devices (e.g. safety switches).
Electrical equipment must be maintained and cleaned regularly.
Pay attention to the danger of crushing on workpiece guides and moving machine parts.
Make sure that no unauthorised persons are in the area of the machine.
Be aware of the risk of injury from flying tool parts in the event of tool breakage.
Therefore wear protective goggles.
Be aware of the risk of injury from flying workpiece parts and chips, splinters and dust coming out
of the machine. Therefore wear protective goggles.
Be aware of the increased noise emission and wear hearing protection.
Be aware of the increased dust generation. Use the extraction system and wear a dust mask if
necessary.

BA_PH_BSB-400-900_EN_44-21.docx

The emergency stop buttons must always be freely accessible. They must not be moved, e.g. with
hopper boxes. Check the function of the emergency stop buttons daily (before starting work).
Laser warning: The machine can be optionally equipped with a laser cut position indicator.
Looking directly into the laser beam will cause serious eye injury!
Fire hazard due to wood dust in connection with flying sparks and/or open fire!
4.1.5 Observe the Environmental Protection Regulations
During all work with the machine, the environmental protection regulations, obligations and laws for waste
avoidance and proper recycling and/or disposal applicable at the place of use must be observed. This applies in
particular to installation, repair and maintenance work involving substances that could pollute the groundwater
(e.g. hydraulic oils and cleaning agents and liquids containing solvents). In any case, prevent them from seeping
into the ground or entering the sewage system.
Store and transport the above-mentioned hazardous substances only in suitable con-
tainers. Avoid leakage of hazardous substances by using suitable collection contain-
ers. Ensure that the above-mentioned substances are disposed of by a qualified dis-
posal company.
4.1.6 Organisational Measures
Always keep this operating manual within easy reach and at the place of use of the machine.
In addition to the operating manual, observe and instruct on generally applicable legal and other binding
regulations for accident prevention and environmental protection.
Supplement the operating manual with further instructions, including supervisory and reporting duties, to
take account of special operational features (e.g. with regard to work organisation, work processes, per-
sonnel employed).
Before starting work on the machine, the person responsible for its operation must have read the operat-
ing instructions, especially the chapter "Safety Instructions". This applies in particular to personnel who
only occasionally work on the machine.
Check that work is carried out in a safety-conscious and hazard-conscious manner and in compliance with
the operating manual.
Operators must not wear open long hair, loose clothing or jewellery (including rings). There is a risk of in-
jury, e.g. by getting caught or drawn in.
Observe the safety instructions and danger warnings on the machine and keep them complete and in legi-
ble condition.
In case of safety-relevant changes to the machine or its operating behaviour, shut down the entire system
immediately and report the fault to the responsible office/person.
Use personal protective equipment as necessary or required by regulations.
Do not make any modifications, additional attachments or conversions to the machine without the manu-
facturer's approval! This will compromise safety and invalidate the manufacturer's warranty and any liabil-
ity claim. The same also applies to the installation and adjustment of safety devices and valves and to
welding work on load-bearing part.
Spare parts must meet the technical requirements specified by the manufacturer. The exclusive use of
original spare parts ensures this. Therefore, only use original spare parts from the manufacturer.
Observe the fire alarm and firefighting possibilities. Make the location and operation of fire extinguishers
(fire class ABC) known. Do not use water!

Machine condition: Check the machine for externally visible damage and defects at least once per shift!
Any changes that have occurred (including those in the operating behaviour) must be reported immedi-
ately to the responsible office or person! If necessary, stop and secure the machine immediately!
Extraction: The machine must be connected to an effective extraction system. This requires a flow velocity
of at least 20 m/s for dry chips and 28 m/s for moist chips (moist 18% or more).
Work area: An obstacle-free work area around the machine is essential for safe operation. The floor
should be level, well maintained and free from debris such as chips and cut-off workpieces.
Cutting area during operation: Never try to remove splinters, chips or other parts from the cutting area
while the machine is running! Never remove splinters and chips by hand!
Special tools: For certain operating phases and operations it is necessary to use special tools for workpiece
feeding (e.g. table fence, push stick, push-block, support bracket etc.).
•When cutting upright workpieces, secure them against tilting, e.g. by means
of a stop bracket, table fence, push-block.
•Secure round workpieces with wedge support or similar against twisting.
•For very short or narrow workpieces use a suitable pushing device.
•Ensure good workpiece support for long or wide workpieces, e.g. with a table extension.
•Do not machine unshaped workpieces that do not fit on the machine table.
Work interruptions: Switch off the machine even during short interruptions! Never leave the machine
running unattended!
When the work is finished: Release the saw blade tension and provide the machine with a warning sign.
Lower the saw blade guard to table height.
Leaving the machine: Switch off the control voltage and main switch before leaving the machine. Never
leave the machine unattended in an unsecured state.
Behaviour in the event of a saw blade breakage: Be sure to wait until all bandsaw wheels have come to a
complete standstill before taking any further action. Only the lower wheel is equipped with a brake!
4.2.3 Special work within the Scope of Maintenance Work as well as Troubleshooting in
the Workflow
Observe maintenance and inspection activities prescribed in the operating manual!
These activities, as well as all other repair work, may only be carried out by qualified personnel!

4.2.4 Safe Working Practices
Whenever possible, a push stick or a comparable aid must be used to feed the workpiece. It is essential to
avoid working with the hands near the saw blade.
When cutting narrow workpieces, generally use a push stick.
Use aids such as auxiliary fence and push handle for concealed cuts.
Use an aluminium profile rail with a narrow contact edge for cutting narrow and low laths.
Always work with all protective devices! These must be in the intended places and in perfect working or-
der. Defective guards must be replaced immediately.
Damaged table inserts are to be replaced with new ones.
Regular maintenance and cleaning of bandsaw blades, extraction system, etc. is required to reduce noise.
Refit removed guards in accordance with the manufacturer's instructions.
Never clean the bandsaw blade or bandsaw wheels with a hand-held brush or scraper while the bandsaw
blade is in motion.
Do not start cutting until the bandsaw blade has reached full speed.
Do not use damaged bandsaw blades.
Check the bandsaw blades regularly for damage.
Replace damaged bandsaw blades immediately.
Only use bandsaw blades suitable for the operation and the material to be processed.
Do not exceed the permissible speed of the bandsaw blade.
Do not use damaged tools.
Damaged parts must be replaced with new ones.
Repairs may only be carried out by qualified personnel with the main switch locked.
The machine is equipped with an automatic motor brake. If the brake no longer brakes within the pre-
scribed braking time (10 s) despite readjustment, the customer service must be informed.
4.2.5 Safety Equipment
The machine is equipped with the following necessary safety devices:
•Complete protection of the saw blade along its entire length.
•The saw blade guard is manually height-adjustable and covers the saw blade from all four sides, preventing
hands from entering the danger zone.
•When the doors / guards are opened, the power supply to the motor is automatically interrupted.
•Additional safety switches prevent unintentional opening of the doors. In order to be able to open the doors
during a belt or wheel change, the safety switches must first be manually unlocked (see section 9.2).
•The bandsaw guide is equipped with a transparent protective cover to ensure a clear view of the cutting
area for the operating personnel. At the same time it partly serves as splinter protection.
•The standard version of the bandsaw machine is equipped with an automatic motor brake that brings the
saw blade to a standstill within 10 seconds in the event of a power interruption.
•The blade tension indicator shows the correct tension of the blade in relation to its width.
•The machine is equipped with an emergency stop switch on the control panel.
4.2.6 Noise
Certain instructions must be followed to avoid an increase in the noise level:
•Sawdust falling between the wheel and the saw blade can cause vibrations that can increase the noise level.
•Only original saw blades with a correct and clean weld must be used.
•The saw blade must be correctly adjusted for the intended work and suitable for the material.
•The instructions for the wheel surfaces (section 15.4) and the saw blade (see section 15.5) must be
followed to keep the parts in good condition and reduce the noise level.

4.3 Danger Zones on the Bandsaw
4.3.1 Danger Zone Bandsaw Blade
Figure 2: Danger zone sawblade
•The area 120 mm around the saw blade is a
danger zone.
•Make sure that your hands are at least 10 cm
away from the saw blade.
•If a minimum distance of 10 cm cannot be
maintained, use a push stick or other suitable
aid for feeding the workpiece.
•When feeding the workpiece, place your hands
flat with your thumbs on them and do not
spread your fingers.
•Lower the guard to a distance of max. 5 mm
from the workpiece.
Danger of cutting and being drawn in! Danger zone of 120 mm around the saw blade!
4.3.2 Danger Zone around the Machine
Another danger zone is located to the right of the machine. Here there is a particular risk of serious injury from
a torn bandsaw blade, which can be ejected in this area. During operation, it is strictly forbidden for the operator
as well as any helpers and possible observers to stay in this area!
Figure 3: Danger zone around the machine
•The operator of the machine must generally
stand in the direction of cutting, in front of the
bandsaw and outside the danger zone.
•A required helper for workpiece removal must
generally stand opposite the cutting direction
and outside the danger zone, behind the ma-
chine, on the opposite side to the operator.
•Any observers must stand in a semicircle outside
the danger zone. An adequate distance must be
kept so that the operator of the machine and a
possible helper are not hindered in their work.
Be aware of the danger posed by an ejecting bandsaw blade in the event of a band break!
Entering the danger zone during operation can lead to very serious injuries.
Only use bandsaw blades that are in perfect condition resp. have been correctly welded, ground
and set. Damaged bandsaw blades must be replaced immediately.

Dimensions and construction subject to change
Space requirement:
The effective space requirement usually de-
pends on the dimensions of the machine and
the dimensions of the workpieces to be pro-
cessed. In general, provide sufficient space
around the machine and also calculate the re-
quired workplace for the operating personnel
and for the infeed and outfeed of the work-
pieces.

5.4 Emission Levels according to EN ISO 3746:2010
5.4.1 Noise Information
The values given are emission levels and therefore do not necessarily represent safe workplace values. Alt-
hough there is a correlation between emission and immission levels, it cannot be reliably deduced whether ad-
ditional precautionary measures are necessary or not.
Factors that may affect the current immission level at the workplace include the duration of exposure, the na-
ture of the workspace, other noise sources, etc., e.g. the number of machines and other activities in the vicin-
ity. The permissible workplace values can also vary from country to country.
However, this information should enable the user to make a better assessment of hazard and risk.

The workplace-related noise emission values of the machine exceed 85 dB(A)!
Therefore, suitable hearing protection must be provided to the personnel!
Note: Regular maintenance and cleaning of the bandsaw blade and extraction system as well as lubrication of
the bandsaw blade guides (back and side rollers, see section 15.2) generally has a positive effect on the ma-
chine's noise level
