BLADE SELECTION (FIG. V)
CAUTION
!
Blade teeth are sharp. Use care when handling a saw
blade.
CAUTION
!
For longest wear and best cutting results, use the
correct blade thickness, width, and temper for the type
of material you will cut.
When sawing small curves and delicate work, use
narrow blades. Otherwise, use the widest blade as
possible. (See Fig. U on page 18)
For cutting wood and similar materials with this band
saw, purchase blades in width up to 1/2 in.(12.7 mm),
and a length of 93-1/2 in.(2374.9 mm).
Do not cut metals with this band saw.

CHANGING SPEED SETTING (FIG. W)
WARNING
!
To avoid injury, turn the power switch OFF and
disconnect the band saw from the power source.
1. Loosen the belt tension by turning the belt tension
handle (6) and rotating the motor counterclockwise
until it stops.
2. Open the lower wheel cover and re-position the
V-belt (3).
● Changing the speed from 1630 to 2730 FPM:
first remove belt (3) from the band saw pulley(4);
reposition in the saw pulley groove (1).
● Change the speed from 2730 to 1630 FPM: first
remove belt (3) from the motor pulley (5) and
reposition in the motor pulley groove (2). Remove
the belt from the saw pulley (4) and reposition in
the saw pulley groove(2).
NOTE: The pulley belt is properly tensioned when
there is 1/2 in. (12.7 mm) deflection if pressed in the
center of the pulleys.
3. Tighten the belt tension by turning the belt tension
handle (6).
NOTE: After re-adjusting belt position and belt tension,
verify and re-adjust the settings for the blade tension
and tracking position, guides and bearings
(See Adjustment section).
