Bow Weight Adjustment
Bow weight is one of the most important
adjustments of the saw. If the bow weight is not
set properly, one can expect poor performance,
crooked cuts, tooth stripping, stalling, and the
blade popping off the blade wheels. The
hydraulic feed rate unit will not compensate for
improper bow weight. Bow weight has been set
at the factory and should not need any
adjustment. If adjustment becomes necessary:
1. Disconnect machine from power source.
2. Turn on hydraulic valve (F, Figure 5).
3. Turn cutting pressure control valve (E,
Figure 5) counterclockwise until it stops.
4. Place one end of a fish-type scale under the
blade tension handle and lift the saw with
the other end. The scale should indicate
approximately 18-20 lbs. for the HBS-916W.
For the HBS-1018W, it should indicate 22-
24 lbs.
5. Adjust tension to approximately 18-20 lbs.
(or 22-24 lbs.) by turning the adjustable C-
bolt found at the end of the coil spring o n
the rear of the band saw.
6. Connect the machine to the power source.
Vise Adjustment
To position the moveable vise jaw:
1. Turn vise handwheel (A, Figure 11) 1/2 turn
counterclockwise.
2. Move rack block (B, Figure 11) to desired
location by sliding along the bed. Place the
rack block onto the rack.
3. Turn the handwheel to tighten the vise.
To adjust the vise for angle cutting:
1. Loosen bolts and move vise jaw (C, Figure
11) to desired location.
2. Set the vise to desired angle, re-install nuts
and tighten the nut and bolt assemblies.
3. Adjust the movable vise parallel to the fixed
vise by loosening bolt (D, Figure 11),
adjusting to parallel, and re-tightening bolt.
