OPERATION
BASIC OPERATION OF THE SCROLL SAW
Before starting a cut, watch the saw run. If you experience
excessive vibration or unusual noise, stop immediately. Turn
the saw off, remove the switch key, and unplug the saw. Do
not restart until locating and correcting the problem.
Note: After the saw is turned ON, a hesitation before blade
movement is normal.
CUTTING PROCEDURES
■
There is a learning curve for each person who wants to
use this saw. During that period of time it is expected that
some blades will break until you learn how to use and
adjust the saw.
■
Plan the way you will hold the workpiece from start to
finish.
■
Keep your hands away from the blade. Do not hand hold
pieces so small your fingers will go under the blade guard.
■
Hold the workpiece firmly against the saw table.
■
The blade teeth cut material only on the down stroke.
■
Use gentle pressure and both hands when feeding the
work into the blade. Do not force the work.
■
Guide the workpiece into the blade slowly because the
teeth of the blade are very small and can only remove
material on the down stroke.
■
Avoid awkward operations and hand positions where a
sudden slip could cause serious injury from contact with
the blade. Never place hands in blade path.
■
To get accurate cuts, compensate for the blade's
tendency to follow the wood grain as you are cutting
wood.
■
Use extra supports (tables, saw horses, blocks, etc.)
when cutting large, small or awkward workpieces.
■
Never use another person as a substitute for a table
extension or as additional support for a workpiece that is
longer or wider than the basic saw table.
■
When cutting irregularly shaped workpieces, plan your
work so it will not pinch the blade. Workpieces must not
twist, rock or slip while being cut.
REMOVING JAMMED MATERIAL
When backing out the workpiece, the blade may bind in the
kerf (cut). This is usually caused by sawdust clogging the
kerf or when the blade comes out of the blade holders. If this
happens:
■
Wait until the saw has come to a full and complete stop.
■
Place the switch in the OFF position, remove the switch
key from the switch assembly. Store key in a safe place.
■
Unplug the saw from the power source.
■
Remove the saw's blade and the workpiece, see section on
Removing the Saw Blade, page 13.
■
Wedge the kerf open with a flat screwdriver or wooden
wedge then remove the blade from the workpiece.
WARNING:
Before removing loose pieces from the table, turn saw off
and wait for all moving parts to stop to avoid serious
personal injury.
AVOIDING INJURY
■
Make sure saw is level and does not rock. Saw should
always be on a firm, level surface with plenty of room for
handling and properly supporting the workpiece.
■
Bolt saw to the support surface to prevent slipping,
walking or sliding during operations like cutting long,
heavy boards.
■
Turn saw off, remove switch key, and unplug cord from
the power source before moving the saw.
■
Do not remove jammed cutoff pieces until blade has come
to a full and complete stop.
■
Choose the right size and style blade for the material
and type of cut you plan to do.
■
Use only recommended accessories.
■
With the exception of the workpiece and related support
devises, clear everything off the saw table before turning
the saw on.
■
Properly support round materials such as dowel rods or
tubing because they have a tendency to roll during a cut
causing the blade to “bite”. To avoid this, always use a
“V” block or clamp workpiece to a miter gauge
■
Before removing loose pieces from the saw table, turn
saw off and wait for all moving parts to stop.
LOCKING THE SWITCH
See Figure 11.
■
Wait until the saw has come to a full and complete stop.
