Operating Guide

Common causes of blade breakage:
● Poor guide alignment and adjustment.
● Forcing or twisting a wide blade around a
short radius.
● Feeding too fast.
● Dull teeth or not enough set.
● Too much blade tension.
● Setting top guide assembly too high
above the workpiece.
● Lumpy or improperly nished braze or
weld on the blade.
● Continuous running of blade when not
cutting.
BLADE SELECTION (FIG. V)
Blade teeth are sharp. Use care when handling
a saw blade.
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)
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 bolt (6) with a suitable wrench
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: rst remove belt (3) from
the band saw pulley(4); reposition in
the saw pulley groove (1).
● Change the speed from 2730 to
1630 FPM: rst 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) deection if
pressed in the center of the pulleys.
3.
Tighten the belt tension by turning the belt
tension bolt (6) with the suitable wrench.
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)
