Changing Blade Speeds; Blade Selection; Blade Removal And Installation; Figure 5: Belt Speed/Position Relationship - Jet VSF-14-1 Operating Instructions And Parts Manual

Changing blade speeds:

1. Disconnect the electrical power from the band saw branch circuit to prevent
accidental motor start-up.
2. Place the saw frame in the rearmost position by pushing down on the saw
frame release lever (Figure 3 Item 2) and lock it by turning the saw frame
release knob (Figure 3 Item 1.2) clockwise.
3. Remove the panel on the base to expose the V-belt and pulleys.
4. Lift the motor to loosen the belt.
5. Select the speed using the placard on the saw head. Put the V-belt in the
pulley grooves of the pulley for the desired speed (Refer to Figure 5 for belt
locations and the speeds available).
6. Lower the motor to tighten the V-belt.

Blade Selection

The band saw is delivered with a saw blade that is adequate for a variety of jobs on a
variety of common materials. Refer to Figure 5 for the speeds recommended for various
materials. These speeds, while appropriate for many common cutting needs, do not
encompass the wide variety of special blade configurations (tooth pitch and set) and
special alloys for cutting unusual or exotic materials.
A coarse blade could be used for a solid steel bar, but a finer tooth blade would be used
on a thin-wall steel tube. In general, the blade choice is determined by the thickness of
the material; the thinner the materials; the finer the tooth pitch.
A minimum of three teeth should be on the work piece at all times for proper cutting. The
blade and work piece can be damaged if the teeth are so far apart that they straddle the
work piece.
For very high production cutting of special materials, or to hard-to-cut materials such as
stainless steel, tool steel or titanium, you can ask your industrial distributor for more
specific blade recommendations. The supplier that provides the work piece material
should be able to provide you with very specific instructions regarding the best blade (and
coolant or cutting fluid, if needed) for the material or shape supplied.

Blade Removal and Installation

Use leather gloves when changing the saw blade to protect your hands from
cuts and scratches. Use protective eye wear that meets ANSI SPECIFICATION
Z87.1.
Disconnect the band saw from its electrical power source.
