SET UP

Blade Tension

DISCONNECT THE MACHINE FROM THE MAINS
SUPPLY.
Ensure that all guide bearings are well clear of
the blade!, (fig 23).
Fig 23-24
Position the tension lever down in full tension
position, (see fig 24).
• Before altering blade tension ensure that the blade
is roughly positioned in the middle of the wheel, you
will need to lower the top wheel slightly by using the
tension lever to do this, (fig 25).
• Turn the blade tension knob clockwise to tension
the blade whilst rotating the top wheel slowly at
first by hand. A gauge at the front of the upper
wheel shows either tension on or tension off, (fig 26).
• The best place to check blade tension is on the left
hand side of the bandsaw. Around 1cm of blade
movement is recommended, (fig 27).
• Changes in blade width will have an effect on blade
tension. Keep in mind that too little blade tension
can cause blade breakage.
• After a period of use it is recommended to recheck
the blade tension and possibly readjust as bandsaw
blades can stretch slightly in use.
TIP: If the bandsaw is to sit idle for a period of time,
place the tension lever in partial tension position;
this will help prevent blade fatigue and tyre
deformation, and save wear on bearings and band
wheels.
