Changing the Blade Speed / Belt Tension
WARNING!
Before changing the speed, always make
sure the machine has been unplugged from the electrical
supply.
This Bandsaw has two blade speeds, low speed (1510 ft/
min) and high speed (3220 ft/min).
The lower wheel (A--Fig. 13) has two integral “V” form
pulleys, and the motor shaft has a twin multi-vee form
pulley (B--Fig. 13). The “V” belt (C--Fig. 13) passes around
the wheel pulley and the motor pulley. The belt tension is
released and applied by using the handwheel (D--Fig. 13).
For the high speed (3220 ft/min), the belt should be fitted
to the rear pulley on both the motor and the wheel, as
shown in Fig. 13.
For the low speed (1510 ft/min), the belt should be fitted to
the front pulley on both the motor and wheel, as shown in
Fig. 13.
To properly adjust belt tension, turn hand-wheel (D--Fig.
13) until there is 1/2” deflection in the “V” belt.
Replacing the Bandsaw Blade
WARNING!
Unplug the machine from the electrical
supply. This ensures that the Bandsaw will not accidentally
turn on if the ON/OFF switch is bumped.
a) Open the top and bottom wheel doors by turning the
door locking knobs.
b) Remove the rip fence rail from the front of the table
by loosening the 4 thumbscrews (Fig. 3 on page 8).
c) Release the blade tension by moving the quick
release lever (A--Fig. 14) from right to left. Open the
hinged door on the blade guard by loosening the
hex screw. (Fig. 15 on page 12)
d) Remove the saw blade by feeding it through the slot
in the table, upper and lower blade guides and the
slot in the spine of the machine, being careful not to
cut yourself. Wear gloves for protection.
e) When installing the new blade, ensure the blade
teeth are pointing downwards and towards you at
