1. Place the sanding pad onto the spindle shaft, and enter the
sanding disc on top of the sanding pad.
2. Insert the sanding disc clamp nut through the disc and
thread onto the spindle as far as you can with your fingers.
3. Press in the spindle lock, and then tighten the sanding pad
securely with the wrench.
ATTACHING WIRE BRUSH
NOTE: Wire brush is not included as a standard accessory.
1. Place the wire brush onto the spindle shaft.
2. Screw the wire brush by hand until it is securely fastened.
AUX. HANDLE
WARNING!
Always use auxiliary handle for maximum control over
torque reaction or kick-back.
Operation of the grinder without the side handle could cause
loss of control of the grinder, resulting in possible serious
personal injury.
The aux. handle (10) can be attached to either side of, or the
upper part of, the gear case, depending on preference and
conform.
MAIN HANDLE (Fig. 8)
(G-2350 only)
The main handle can be set to any of three positions (0° and 90°
right and left) by rotating the main handle (11) while the release
button (12) is pressed down.
CAUTION!
Before operation, make sure the release button is returned
to lock position, and the main handle is fixed in either
position.
POWER-ON INDICATOR
The power-on indicator turns on once the tool is connected
to electric power supply. This warns the user that the tool is
connected and will operate when the switch is pressed.
OPERATION
KEEP THE WHEEL GUARD IN PLACE.
NEVER COVER AIR VENTS SINCE THEY MUST ALWAYS BE
KEPT OPEN FOR PROPER MOTOR COOLING.
GRINDING
The key to efficient operating is controlling the pressure and
surface contact between the disc and work piece. Flat surfaces
are ground at an acute angle, (usually 10 to 20 degrees) to the
work piece. Allow the disc to reach full speed before starting to
grind. Too great an angle causes concentration of pressure on a
small area which may gouge or burn the work surface.
WARNING!
Excessive or sudden pressure on the wheel will slow
grinding action and put dangerous stresses on the wheel.
SANDING
1. For best results, tilt the Disc Sander at a 10° to15° angle
while sanding so that only about 1” of the surface around
the edge of the disc contacts the work.
2. If the disc (accessory) is held flat or the back edge of the
disc comes in contact with the work, a violent thrust to the
side may result.
3. If sander is tilted too much, sanding action will be too great
and a rough cut surface or gouging and snagging will result.
4. Guide the Disc Sander with crosswise strokes. Be careful
not to hold the sander in one spot too long. Do not use a
circular motion, as this makes swirl marks. Test before use
on scrap stock.
5. Do not force or apply pressure when sanding. Use only the
weight of the tool for pressure.
Excess pressure actually slows the tool down. If faster stock
removal is desired, change to a coarser grit disc.
6. Remove gummy paint from metal with an “open coat” disc.
Sand until sparks start to appear, then stop and change to a
“closed coat” disc to remove any remaining paint.
a) SANDING WOOD
1. When sanding wood the direction of the disc motion at
the contact point should parallel the grain as much as
possible. The rapid cut of discs and the swirl type scratch
pattern they occasionally create generally prohibit their
use for producing the final finish.
2. Scratches and circular marks are usually the result of
using too coarse a grit. When changing to a finer grit,
move across the sanding lines that were made by a
previous coarser disc.
b) SANDING METAL
1. When sanding automobiles or appliances, wipe the
metal clean with a non-flammable solvent or commercial
cleaner to remove all wax and grease. By doing this first,
the sanding discs will sand better and last longer.
2. For heavy duty work, use a coarse grit disc first, and
follow-up with a medium grit to remove scratches. To
produce smooth finish, use fine grit disc.
WIRE BRUSHING
1. Wire brushes are intended to “clean” structural steel,
castings, sheet metal, stone and concrete. They are used to
remove rust, scale and paint.
2. Avoid bouncing and snagging the wire brush, especially
when working corners, sharp edges, etc. This can cause
loss of control and kickback.
NOTE:
Operate the brush with the lightest pressure so only
the tips of the wire come in contact with the work.
If heavier pressures are used, the wires will be
overstressed, resulting in a wiping action; and if this is
continued, the life of the brush will be shortened due
to wire fatigue.
MAINTENANCE
After use, check the tool to make sure that it is in top condition.
It is recommended that you take this tool to a Ryobi Authorized
Service Center for a thorough cleaning and lubrication at least
once per year.
DO NOT MAKE ANY ADJUSTMENTS WHILE THE MOTOR IS
IN MOTION.
ALWAYS DISCONNECT THE POWER CORD FROM THE
RECEPTACLE
BEFORE CHANGING REMOVABLE OR EXPENDABLE
PARTS (BLADE, BIT, SANDING PAPER ETC.), LUBRICATING
OR WORKING ON THE UNIT.
WARNING!
To ensure safety and reliability, all repairs should be
performed by an AUTHORIZED SERVICE CENTER or other
QUALIFIED SERVICE ORGANIZATION.
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
