Routine Maintenance
Keep the Saw Clean
Dust and debris from some materials can be extremely
abrasive and cause components within the saw to wear
prematurely. It is important to keep moving parts cleared of
abrasive dusts.
► As a general rule, keep the saw clean of all dust and
debris. Even soft-wood dust can be abrasive over time.
► Examine all moving parts for dust and debris.
► Keep the bevel hinges clean of dust using compressed
air or cotton swabs. If the hinges wear due to abrasive
particles, the saw will not perform optimally.
► Keep the blade area and dust extraction port clean of
debris. Debris can cause wear and reduce the effective-
ness of the dust extraction system.
► Periodically remove the blade cover (5 screws), the blade,
and the inboard arbor ange; and clean any built up
debris from the inside of the saw.
Keep the Sawblades Sharp
Using a dull sawblade can be extremely dangerous and
provide poor cut quality.
► Never attempt to sharpen a sawblade manually. Special
equipment is necessary to properly sharpen a circular
sawblade. An improperly sharpened sawblade can injure
the operator, destroy the saw, and damage the workpiece.
► The sawblades should be sharpened regularly, and only by
a qualied sharpening service.
► Improper grinding of the carbide teeth of a sawblade can
result in serious injury to the saw operator.
Adjust and Inspect the Saw
To ensure the saw is in proper working order, periodically
inspect the operation of the saw and ensure it is properly
adjusted.
► Observe the function of the saw during normal operation.
► Unusual sounds are indicative of pending problems.
► A reduction in the cut quality indicates the saw is either
improperly adjusted or not functioning properly.
► A reduction in cutting power or speed may indicate a dull
blade or a motor problem.
► If any of the safety devices on the saw are inoperable
or disabled, immediately stop using the saw and have it
serviced.
► Periodically inspect the wear bars for the guide rail cams
for wear.
