Installing/Removing Battery Pack - Ryobi P450 Manuel D'utilisation

WARNING:
Before connecting the sander to a power supply, always
make sure it is not in the "locked-on" position. Failure
to do so could result in accidental starting of the sander
resulting in possible serious injury.
To lock- on the sander:
 Depress the switch trigger.
 Push in the lock-on button.
 Release the switch trigger.
 Release the lock-on button.
NOTE: To release the lock, depress and release the switch
trigger.

INSTALLING/REMOVING BATTERY PACK

See Figure 2, page 10.
To install:
 Insert the battery pack.
 Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured in the
product before beginning operation.
To remove:
 Depress the latches on each side of the battery pack.
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish.
Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding.
In general, when sanding, coarse grit removes the most
material and fine grit produces the best finish. The condition
of the surface to be sanded determines which grit will do the
best job. If the surface is rough, start with a coarse grit and
sand until the surface is uniform. Then use medium grit to
remove scratches left by the coarser grit. Finally, use finer
grit for finishing the surface. Always continue sanding with
each grit until the surface is uniform.
USING SANDING BELTS
See Figures 3 - 5, page 10.
To install/change sanding belts:
 Remove the battery pack.
 Position the sander on its side.
WARNING:
Keep hands and fingers clear of both rollers and spring
mechanism at all times. Failure to do so could result in
fingers getting pinched, causing serious injury.
OPERATION
 Raise the tension release lever.
NOTE: If you are changing sanding belts, remove the old
sanding belt at this time.
 Install the sanding belt.
CAUTION:
If the sanding belt is not a bidirectional belt, ensure that
the arrow inside the belt is pointing in the direction of the
rotation (clockwise when looking into the open side of the
sander). Installing unidirectional sanding belts backwards
can create a hazardous condition.
 Align the sanding belt to its correct position.
 Lower the tension release lever to secure the sanding
belt.
TO ADJUST SANDING BELT TRACKING
See Figures 6 - 7, page 11.
Belt life is greatly increased if you regularly adjust the sanding
belt tracking. When correctly adjusted, the outer edge of
the sanding belt should be even with the outer edge of the
base of the sander.
When you install a new sanding belt, you may need to adjust
the sanding belt tracking several times until the belt becomes
conditioned.
WARNING:
Before connecting the sander to a power supply, always
make sure it is not in the "locked-on" position. Failure
to do so could result in accidental starting of the sander
resulting in possible serious injury.
Follow these steps to adjust sanding belt tracking.
 Insert the battery pack.
 Position the sander upside down.
NOTE: This position is for adjustments only. The sanding
belt should not contact a workpiece or any foreign object
when you are making belt tracking adjustments.
 Depress the switch trigger and release immediately.
 Choose one of these options:
• Sanding belt runs inward: Turn the tracking knob
slowly counterclockwise.
• Sanding belt runs outward: Turn the tracking knob
slowly clockwise.
NOTE: Turn the tracking knob until you are sure the
sanding belt is secure, i.e., it will not come off the sander
or contact internal parts.
