Maintenance - Ryobi RS290 Manual Del Operador

WARNING:
Before connecting the sander to power supply source,
always check to be sure the switch is not in the ON
position. Failure to do so could result in accidental starting
of the sander resulting in possible serious injury.
Do not press down on the sander. The weight of the unit
supplies adequate pressure, so let the sanding disc and
sander do the work. Applying additional pressure only slows
the motor, rapidly wears sanding disc, and greatly reduces
sander speed. Excessive pressure will overload the motor
WARNING:
Before inspecting, cleaning, or performing any maintenance,
wait for all moving parts to stop and disconnect from the
power supply. Failure to follow these instructions can result
in death, serious personal injury, or property 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.
WARNING:
When servicing, use only identical replacement parts. Use
of any other parts could create a hazard or cause product
damage.
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.

OPERATION
causing possible damage from motor overheating and can
result in inferior work. Any finish or resin on wood may soften
from the frictional heat. Do not allow sanding on one spot
too long as the sander's rapid action may remove too much
material, making the surface uneven.
Extended periods of sanding may tend to overheat the mo-
tor. If this occurs, turn sander off and wait until sanding disc
comes to a complete stop, then remove it from workpiece.
Remove the hand from vent area, remove sanding disc, then
with the hand removed from vent area, turn sander on and
run it free without a load to cool motor.

MAINTENANCE

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.
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, commuta-
tors, etc. Consequently, we do not recommended using this
tool 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 tool using compressed air.
LUBRICATION
All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
