Maintenance - Urrea SK816 Manual De Usuario

• Place the workpiece on the saw table with
the drilled hole over the access hole in the
table.
• Install blade through the hole in the work-
piece; adjust the drop foot and blade tension.
• When finished making the interior scroll cuts,
simply remove the blade from the blade hold-
ers as described in the section on Installing
Blades, and remove the workpiece from the
saw table.
STACK CUTTING
After becoming well ac-
quainted with your saw
through practice and
experience, you may
wish to try stack cut-
ting. Stack cutting may
be used when several
identical shapes need
to be cut. Several pieces
of wood may be stacked on top and secured
to each other before cutting. The wood piec-
es may be joined together by placing double
sided tape between each piece or by wrapping
masking tape around the corners or ends of
the stacked wood. You must attach the stacked
pieces of wood to each other so they will move
on the table as a single piece of material.
WARNING: To avoid possible, serious per-
sonal injury, do not cut more than one loose
piece of material at a time. Do not allow fa-
miliarity with your saw to make you careless.
Remember that a careless fraction of a second
is sufficient to inflict severe injury.

MAINTENANCE

WARNING: When servicing, use only iden-
tical replacement parts. Use of any other part
may create a hazard or cause product damage.
GENERAL MAINTENANCE
• Keep your scroll saw clean.
• After cleaning the table top initially, apply
a thin coat of automobile type (paste) wax to
the table top so the wood slides easily while
cutting.
• Do not allow pitch to accumulate on the saw
table. Clean with gum and pitch remover.

ARM BEARINGS
Lubricate the arm bearings after the first 10
hours of use. Oil after every 50 hours of use or
whenever there is a squeak sound coming from
the bearings.
• Carefully place the saw on its side.
Remove the rubber cap from the upper and
the lower arm of the saw.
• Squirt a few drops of SAE20 oil around the
shaft end and arm bearings. Let oil soak in
overnight, remaining in this position.
Note: Lubricate the bearings on the other side
of the saw in this same manner.
WARNING: If the power cord is worn, cut,
or damaged in any way, have it replaced imme-
diately by a qualified service technician. Failure
to do so could result in serious personal injury.
MOTOR BRUSHES
Your saw has externally accessible motor brush
assemblies that should be checked periodically
for wear. When one of the two brushes be-
comes worn, replace both brushes.
• Unplug the saw from the power source.
• Carefully place the saw on its side exposing
the under- side of the saw housing.
• Using a flat blade screwdriver, remove the
bottom brush assembly cap through the access
hole in the base and the top brush assembly
cap from the top of the motor. Gently pry the
brush assemblies out using a small screw driver,
point of a nail, or paper clip.
• If one motor brush is worn down shorter than
1/4 in. (6 mm), replace both motor brushes. Do
not replace one side without replacing the
other. Make sure curvature of brush matches
curvature of motor and that the motor brush
moves freely in brush tube. Use the blunt end
of something thin (eraser end of pencil, etc.)
to push the motor brush into the tube until it
stays.
• Make sure the motor brush cap is oriented
correctly (straight). Tighten motor brush cap
using a hand powered screwdriver only. Do not
overtighten.
WARNING: To prevent accidental starting
that could cause possible serious personal in-
jury, turn off and unplug the saw before main-
taining or lubricating your scroll saw. Failure to
unplug your saw could result in accidental start-
ing causing serious injury.
