WARNING:
When servicing, use only identical Ryobi 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
See Figure 15.
Lubricate the arm bearings after the first 10 hours of use. Oil
after every 50 hours of use or whenever there is a squeak
coming from the bearings.
■
Carefully place the saw on its side as shown in
Figure 15.
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 immediately by a qualified service
technician. Failure to do so could result in serious personal
injury.
MOTOR BRUSHES
See Figure 16.
Your saw has externally accessible motor brush assemblies
that should be checked periodically for wear. When one of
the two brushes becomes 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
drivier, 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.
