WARNING:
When servicing, use only identical replacement parts.
Use of any other parts can create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken, or
destroy plastic which could result in serious personal
injury.
Keep the 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. Do not use gasoline.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to accelerated
wear and possible premature failure because the fiberglass
chips and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this product for extended work on these types
of materials. However, if you do work with any of these
materials, it is extremely important to clean the product
using compressed air.
MAINTENANCE
ARM BEARINGS
See Figure 14, page 18.
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
.
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.
MOTOR BRUSHES
See Figure 15, page 18.
The 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 underside
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 screwdriver,
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.
