2. SAFETY PRECAUTIONS
2.1 SAFETY REGULATIONS
WARNING Read carefully the operation and maintenance manual before starting, using, servicing
and carrying out any other operation on the machine.
The manufacturer disclaims all responsibilities for damages to persons or things, which might be caused by any failure to
comply with the safety regulations.
- It is prohibited to use the machine when under the influence of alcohol, drugs or medication.
- The operators must carefully read the manual paying particular attention to the warning and safety notes. Furthermore,
they must be informed on the dangers associated with use of the machine and the precautions to be taken, and must be
instructed to periodically inspect the guards and safety devices.
- Before carrying out adjustment, repair or cleaning work, disconnect the machine from the electric power by
setting the main switch to stop.
- After an initial bedding-in period or many hours of operation, the driving belts may slacken; this causes an
increase in the tool stopping time (the stopping time must be less than 10 seconds). Immediately tighten them.
-3-

3.3 ELECTRICAL CONNECTION
- Electrical installation should be carried out by competent, qualified personnel.
- The mains connection should be made using the terminal box.
- Replacement of the power supply cable should only be done by a qualified electrician.
WARNING
To avoid electrocution or fire, any maintenance or repair to electrical system should be done only by qualified electricians
using genuine replacement parts.
3.4 NOISE LEVEL
No load load
Sound Pressure Level
<80dB(A)
<90dB(A)
Sound Power Level
<90dB(A)
<100dB(A)
The noise levels measured are emission levels and not necessarily the safe working level. Although there is a
correlation between the emission levels and the exposure levels, this cannot be used reliably to determine whether or
not further precautions are required. The factors which affect the actual level of operator exposure include the duration
of exposure, the ambient characteristics and other sources of emission, for example, the number of machines and other
adjacent machining. The permitted exposure values may also vary from country to country. Nevertheless, this
information allows the user of the machine to better evaluate the dangers and risks.
Other factors which reduce exposure to noise are：
- correct tool choice
- tool and machine maintenance
-use of hearing protection systems(e.g. headsets, earplugs,…)
WARNING Please use the hearing protection systems if the above mentioned noise levels exceed 95dB(A).
3.5 DUST EXTRACTION
If this band saw is operated indoors, it is recommended to have it connected to a dust collector. The suction connector,
supplied with the machine, has to be fitted to the dust ejection port of the saw for this purpose. The diameter of the
suction connector is 100mm.
- People usually process oak or beech wood will have membrane mucosa nasi much easier than others
- Experience shows that skin contact with oak or beech dust does not cause cancer
WARNING Wood dust and chips, together with an ignition source and the oxygen in the ambient air, can
cause fires and explosions, injuries and allergies.

4. INSTALLATION
4.1 INSTALLATION ZONE CHARACTERISTICS
WARNING
It is prohibited to install the machine in explosive environments.
The installation zone must be selected evaluating the work space required depending on the dimension of the pieces to
be machined, and taking into account that a free space of at least 800mm must be left around the machine. It is also
necessary to check the floor capacity and its surface, so that the machine base is evenly resting on its four supports. A
power outlet and a chip-suction system connection shall be close to the selected machine setting and it must be
conveniently lighted.
4.2 INSTALL OF LOOSE PARTS-INTRODUCTION
A few elements will be disassembled from the machine main structure due to packaging and shipping requirements.
These loose parts should be installed as follows.
WARNING
Please tighten all bolts and nuts absolutely. Otherwise, may cause machine wobble or serious injury to the operator or
other persons.
4.2.1 INSTALL TABLE

- Faucet spanner
- Put the table A onto the trunnion. Aline the mounting
holes which are on the bottom of table to the four holes
on trunnion.
- Use four hex bolt 1, four teeth washer 2 and four flat
washer 3 to mount the table A to trunnion.
Fig.4.2.1
4.2.2 INSTALL FRONT RAIL AND RIP
FENCE
- Put nut 2 and washer 3 on front rail 1
- Make front rail through table A, after leveling rail, lock
by other nut and washer.
- Along with rail A, slide RIP FENCE B on the table

5. ADJUSTMENT AND OPERATION
WARNING
Handle the tools with protective gloves.
5.1 CENTERING TABLE AND TILTING
- Centering table can be adjusted. Loosen the four bolts
which hold the lower table trunnion, and adjust freely.
Place the blade in the middle of the faucet and make it be
parallel to the slotted side of table.
- The table can be tilted from 0 to 45 degree. To tilt, loosen
the wing nut A of the table trunnion. Tighten the wing nut
again when we get the required angle.
- It is recommended to verify the correct angle setting by
making trial cuts in scrap wood.
5.2 SETTING TABLE SQUARE WITH BLADE
Fig.5.1
- Please refer to Fig 5.1
- Loosen the wing nut on the trunnion and check the table with a square and adjust the table at 90 degree with the blade,
then adjust the pointer to 0 degree.
5.3 CHANGING AND SETTING THE BLADE
- This band saw is factory-equipped with a general
purpose wood cutting blade, the blade set. To change the
blade, remove the connect board from the table. Then
loose the quick tension handle C and blade tension handle
A, take down the blade.
- After change blade, firstly adjust tension handle C, then
adjust blade tension handle A, and rotate upper wheel
and adjust handle B, make the blade in the middle of
rubber wheel position. Then clamp the wing nut on clamp
handle B.
Fig.5.3
5.4 BLADE GUIDING
- The saw blades guides of this band saw ensure an exact
guiding of the blade for clean cuts. When using narrow
blades, ensure that the lower blade guide positively
support the blade from both sides and the rear. Set
bearings of the upper blade guide to within approx. 0.5mm
of the blade, or the guide bearings will be easily broken.
