INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure the power On/Off Switch (72) of the Scroll Saw is in its “OFF”
position and that the tool is unplugged from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures. Note: All repairs should be done by a
qualified technician.
1.
Before each use, inspect the general condition of the Scroll Saw. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts, damaged
electrical wiring, and any other condition that may affect its safe operation. If abnormal
noise or vibration occurs, have the problem corrected before further use. Do not use
damaged equipment.
2.
Periodically recheck all nuts, bolts, and screws for tightness.
3.
Applying a light coat of paste wax on the Saw Table allows the material being cut to
glide smoothly across the Saw Table (53) surface. Buff the wax off with a clean cloth
after application.
4.
If the Power Cord (2) is worn, cut, or damaged in any way, replace it immediately.
6.
Clean the Scroll Saw by using compressed air to blow off dirt and dust.
7.
Store in a clean and dry location.
8.
Over time, if the performance of the Scroll Saw diminishes, or it stops working
completely, it may be necessary to replace the Carbon Brushes in the Motor (51) by
removing the Carbon Brush Holder (84) and inspecting the Carbon Brushes (83). This
procedure should be completed by a qualified technician. If the Carbon Brushes are
not worn down, try cleaning the Carbon Brush tips with an ink eraser.
Lubrication
1.
Lubricate the Oil Bushings (25) of Lower Rocker Arm (22) and Upper Rocker Arm (29)
after the first 10 hours of use. After that, oil them every 50 hours of use, or whenever
noise is heard from the Oil Bushings.
Caution: Do not attempt to oil the motor bearings or ser-
vice the motor internal parts.
2.
Carefully place the Scroll Saw on its side as shown
below.
3.
Squirt a few drips of light oil on the end of the Oil
Bushings.
4.
Leave the Scroll Saw in this position over night to
allow the oil to seep in.
5.
The next day, repeat steps 1 to 4 on the other side of
the Scroll Saw.
6.
Wipe up excess oil with a cloth.
