Maintenance
WARNING: Always turn the switch OFF and unplug the power cord from the outlet
before maintaining or lubricating the scroll saw.
To ensure that the wood glides smoothly across the work surface, periodically apply a coat of paste
wax (sold separately) to the surface of the worktable. If the power cord is worn out or damaged in
any way, replace it immediately. Do not attempt to oil the motor bearings or service the motor's
internal parts.
Lubrication (Fig. 21)
Lubricate the arm bearings after every 50 hours of
use.
1. Turn the saw on its side and remove the cover.
2. Squirt a generous amount of SAE 20 oil
(lightweight motor oil, sold separately) around
the shaft and bearing.
3. Let the oil soak in overnight.
4. Repeat the above procedure for the opposite side of the saw.
Blades
To maximize the life of your scroll saw blades:
1. Do not bend blades when installing.
2. Always set proper blade tension.
3. Use the right blade (see instructions on replacement blade packaging for proper use).
4. Feed the work correctly into the blade.
5. Use thin blades for intricate cutting.
CAUTION: Any and all servicing should be performed by a qualified service center.
