Maintenance - Ryobi ERO240RG Owner's Operating Manual

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
motor. If this occurs, turn sander off and wait until sanding
disc comes to a complete stop, unplug the sander, then
remove it from the workpiece. Allow the tool to cool down.
ORBITAL MOTION
See Figure 2.
Orbital motion is ideal for fast cutting action when removing
old fi nishes, smoothing rough wood, cutting stock down to
required dimensions or for fi nishing surfaces to be painted.
The sandpaper moves in tiny circles at a very high speed,
allowing the sander to move easily.
Collected sanding dust from sanding surface coatings
such as polyurethanes, linseed oil, etc., can self-ignite
in your sander dust collection box or elsewhere and
cause fi re. To reduce the risk of fi re always empty your
dust collection box frequently (10-15 minutes) while
sanding and never store or leave a sander without
totally emptying its dust collection box. Also follow the
recommendations of the coatings manufacturers.
USING THE DUST BAG ASSEMBLY
The dust bag assembly provides a dust collection system
for the sander. Sanding dust is drawn up through the holes
of the sanding disc and collected in the dust bag during
sanding.
TO ATTACH THE DUST BAG ASSEMBLY
See Figure 3.
Follow these directions to attach the dust bag assembly.
1. Unplug the tool.
Failure to unplug the tool could result in accidental
starting causing possible serious injury.
2. Using a slight twisting motion, fi rmly slide the dust
collection bag assembly in the blower exhaust on the
sander.
EMPTYING THE DUST COLLECTION BAG ASSEMBLY
See Figure 4.
For more effi cient operation, empty the dust collection
box when it is no more than half full. This will permit the
air to fl ow through the dust collection box better. Always
empty and clean the dust collection box thoroughly upon
completion of a sanding operation and before placing the
sander in storage.

LIVE TOOL INDICATOR
This tool features a live tool indicator which illuminates as
soon as the tool is connected to the supply. This warns the
user that the tool is connected and will operate when the
switch is pressed.

MAINTENANCE

The tool should never be connected to a power supply
when you are assembling parts, making adjustments,
cleaning, performing maintenance, or when the tool is
not in use. Disconnecting the tool will prevent accidental
starting that could cause serious injury.
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
GENERAL
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to various types of commercial
solvents and may be damaged by their use. Use clean
cloths to remove dirt, carbon dust, etc.
Do not at any time let brake fl uids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. They contain chemicals that can
damage, weaken or destroy plastic.
Electric tools used on fi berglass material, wallboard,
spackling compounds,
accelerated wear and possible premature failure because
the fi berglass chips and grindings are highly abrasive to
bearings, brushes, commutators, etc. Consequently, we
do not recommend using the tool for extended work on
these types of materials. However, if you do work with any
