Adjusting Blade Tension - Delta ShopMaster BS220LS Instruction Manual

OPENING AND CLOSING
HINGED DOOR
When making adjustments such as changing the blade,
tracking the blade, blade guide adjustments, etc., the
hinged doors (A) and (B) Figs. 15 and 16, can be opened
as follows:
NEVER OPEN THE HINGED DOOR
WHEN THE MACHINE IS RUNNING.
1. Pull out on the two door knobs (C) and (D) Fig. 15, and
swing doors (A) and (B) open.
2. Fig. 16, illustrates doors (A) and (B) in the open
position.
3. To close and fasten doors (A) and (B), Figs. 15 and 16,
press on door directly over door knobs (C) and (D) Fig. 15,
until latches snap into the locking position.
ADJUSTING
BLADE TENSION
With the saw blade centered on the two band saw
wheels, slightly loosen wing nut located behind knob (D)
Fig. 17. Turn the tension knob (A) Fig. 17, clockwise to
increase blade tension or counter-clockwise to decrease
blade tension until the indicator (B) lines up with the cor-
responding blade width on scale (C). Tighten wing nut
located behind knob (D). NOTE: The scale is correct for
average work, and is not affected by use of re-brazed
saw blades. We urge you to use the scale until you have
become familiar enough with the operation of the band
saw to vary the tension a little for different kinds of
blades or work. Over-tensioning is a common cause of
blade breakage and unsatisfactory blade performance.
When the band saw is not in use, it is good practice to
release tension to prolong the life of the blade.
