Tensioning The Blade

NOTE: Your bandsaw can use only 1/4" (6mm) wide blades, 56-1/8" (1425mm) long. A blade 
is included with this saw. Ensure that, the tension lock knob is tightened before turn on the 
machine.

To  check 

blade 

tension, 

push 

thumb 

against 

side 

of  blade 

between 

lower 

wheels.  Blade  should  move  only  slight ly 
with  moderate  pressure. 

Be  careful  not  to 

over

tension 

blade. 

Retighten 

tension 

lock knob.

If  too  much  blade  tension  has  been  applied,  blades  may tend  to  break  more  easily  and  blade life 
will be shorter. If  too  little  blade  tension  has  been  applied,  blade  may  not  track  easily,  may  slip 
on  whe els,  or  will  move  too  easily  when  checking  tension. 

Note:  (1)

Tension  lock  knob  must  be  tighten  before  mo ving  blade.

(2)    Loosen   the  tension   adjusting  knob  a  little  after  usage,  (to  lengthen  the  blade's  life 

but  ensure  that  the  tension  lock  knob  is  still  fix on  the  band  saw).

7.  Loosen  the  three  (3)  cover  knobs  by  turning 

counterclockwise and remove cover.

NOTE: Replace  the  bandsaw  cover  after  blade  is 
properly installed, tensioned and tracked.

8.  Loosen  the  two  screws  that  secure  the  lower 

blade  guides  and  separate  them  about 1/8".

9.    Loosen  the  screw  holding  the  lower  blade 

guide  support  and  slide  support  all  the  way 
toward  the  rear  of  the  saw,  and  retighten  all 
screws.

Warning: 

To  avoid  being  scraped  should  blade 

suddenly 

uncoil, 

wear 

safety 

goggles 

and 

carefully 

uncoil  the  blade  holding 

it  at  arms 

length.

10.  Place  the  blad e  over  the  wheels  with  the  teeth 

pointing  downward  toward  the  table 

as 

shown.  Make  sure  the  blade  is  in the center 
of the rubber tires.

Loosen the tension lock knob a little (1/4   
of   a   turn   counter-clockwise).

Turn the tension adjusting knob clock-
wise   until    blade  has  proper  tension.

Turn  the  wheel  by  hand  clockwise 

a  few 

turns  and  notice  if  the  blade  remains 

in 

the  approximate 

center  of  the tires.
