Maintenance - RIDGID R4518T Operator's Manual

MAINTENANCE

WARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1 during
product operation. If operation is dusty, also wear
a dust mask.
WARNING:
Before performing any maintenance, make sure
the tool is unplugged from the power supply and
the top button on the switch is not depressed.
Failure to heed this warning could result in
serious personal 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 may
result in serious personal injury.
 Periodically check all clamps, nuts, bolts, and screws for
tightness and condition. Make sure the throat plate is in
good condition and in position.
 Check the blade guard assembly for proper installation, fit,
clearances, and for free movement. Some wood types may
cause a buildup of dust, pitch, or resin on components,
so regular maintenance and cleaning is recommended.
Any cleaner used must be appropriate for use on plastic
parts.
 Clean plastic parts only with a soft damp cloth. Do
not use any aerosol or petroleum solvents.
 Protect the blade by cleaning out sawdust from underneath
the table and in the blade teeth. Clean blade teeth with
a solvent recommended for gum and pitch removal.
 To maintain the table surfaces, fence, and rails, periodically
apply paste wax to them and buff to provide smooth
functioning. To prevent work from slipping during cutting
operation, do not wax the working face of the miter gauge.
LUBRICATION
This saw's motor bearings have been packed at the factory
with proper lubrication.
 Clean screw threads and nuts with a solvent recommended
for gum and pitch removal.
 Lubricate screw threads, nuts, and bearing points
(including those on the blade guard assembly and miter
gauge).
CLEANING THE RIVING KNIFE LOCK LEVER
PLATES
See Figure 71.
The lock lever on the riving knife may become difficult to
lock securely after extended use due to sawdust or debris
falling into the plates.
 Unplug the saw.
 Unlock the lever to remove the riving knife.
 Wipe the area with a clean dry cloth or use compressed
air to blow away debris.
 Clean the riving knife.
 Reinstall the riving knife and turn the lever to lock the
riving knife in place.
NOTE: If the lock lever is difficult to move or will not
fully close after the plates have been cleaned, contact
customer service.
WARNING:
Do not use the saw if the lock lever does not
fully close. Doing so may cause serious personal
injury.
