Work piece Holder
Adjusting the height:
To prevent the workpiece from lifting, the work piece
holder (14) should be adjusted so it just sits on top of
the workpiece. The work piece holder (14) should not
be adjusted so tightly that the workpiece drags.
Loosen the work piece holder lock knob (2) (Fig. 10).
Lower or raise the work piece holder (14) to the
desired position.
Retighten the work piece holder lock knob (2).
Adjusting the angle:
When bevel cutting the work piece holder (14) requires to be adjusted so its parallel
to the table (7). (as described in “Bevel Cutting” page 14).
Sawdust Blower
The variable speed scroll saw features a sawdust blower (5) to direct air to the most
effected point on the cutting line. Make sure the work piece holder (14) is properly
adjusted, as explained above, to secure the workpiece and direct air at the cutting
surface.
caution:
Do not overtighten, damage could occur to sawdust blower (5).
adjusting Blade tension
Tension (or tighten) the blade by turning the blade tension knob (1) clockwise.
Release (or loosen) the blade by turning the blade tension knob (1) anti-clockwise.
Check tension by the sound the blade makes when plucking the blade, simular to
plucking a guitar string. This requires good knowledge of your scroll saw.
Pluck the back edge of the blade while turning the blade tension knob (1).
The sound should be a musical note. The sound becomes less flat as tension
increases. The sound level will decrease with too much tension.
note:
Be careful as over tension may cause the blade to break as soon as you start
cutting. Too little tension may cause the blade to bend or break.
