3.4 Safety devices 

Upper blade guard

 

 

The upper blade guard 

(26) 

protects 

against unintentional contact with the saw 

blade and from chips flying about.   

In order for the upper blade guard to 

provide adequate protection against 

contact with the band saw blade, it must 

always be set as close as possible 

against the workpiece (max. distance 3 

mm). 

Lower blade guard 

The lower blade guard 

(27) 

protects 

against unintentional contact with the saw 

blade. 

The lower blade guard must always be in 

place and cover the band saw blade while 

the band saw is running. 

Housing doors 

The housing doors 

(25) 

protect against 

contact with the rotating parts inside the 

machine. 

Both

 

housing doors must be closed 

while the machine is in use. 

Push stick 

The push stick serves as an extension of 

the hand and protects against accidental 

contact with the saw blade. 

The push stick must always be used if 

the distance between band saw blade 

and a rip fence is less than 120 mm. 

Guide the push stick at an angle of 20

° 

… 30

° 

against the saw table's surface.

 

 

 

When the push stick is not used it can 

be stored on the push stick holder 

provided at the band saw frame. 

Replace push stick if damaged.

 

 

4. Transport                         

 

• 

Set upper blade guide to its lowest 

position. 

 • 

Remove projecting accessories. 

• 

When shipping, use original packing 

if possible. 

 

5. Machine Details        

Note:

 

 

In this chapter the essential 

operating elements of the machine are 

introduced.

 

The proper use of the machine is 

described in chapter "Operation". Read 

this chapter before using the saw for the 

first time.

 

 

ON/OFF switch with emergency stop 

• 

To start = press the green switch 

button 

(29)

To stop = press the red switch 

button(

28

) or the cover(

In the event of a voltage failure an 

undervoltage relay trips. This prevents 

the machine from starting up when the 

power is restored. To restart, the green 

switch button must be pressed. 

The cover of the ON/OFF switch 

(30)

 can 

be safeguarded by a padlock.

tension 

With the setting knob 

(31) 

the band saw   

blade tension is corrected, if necessary: 

-

 

Turning the setting knob clockwise 

increases the blade tension. 

-

 

Turning the setting knob counter- 

clockwise reduces the blade tension.

(32) 

the saw 

blade tension is released.
