Helpful Tips - Ryobi P450 Manuel D'utilisation

The sander is designed to provide the proper weight on the
sanding belt. Excessive pressure will result in the following:
 Uneven work
 Clogged sanding belts
 Premature sanding belt wear
 Possible motor burnout
 Irregular sanding belt tracking
PROPER HAND PLACEMENT
See Figure 11, page 11.
For ease of operation and maintaining proper control, the
sander has a front handle and a rear handle. These handles
allow two-handed operation, which aids in maintaining
control, keeping the sanding area level with the workpiece,
and keeping hands clear of the sanding belt. When operating
the sander, always hold the front handle with your left hand
and the rear handle with your right hand.
WARNING:
Keep hands and fingers clear of moving sanding belt,
front idler roller, and drive roller assembly. Failure to do
so will result in serious personal injury.

WARNING:
This product and some dust created by power sanding, sawing, grinding, drilling, and other construction activities may
contain chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive

WARNING:
Do not let your fingers rest over the front or right edge
of the sander. If the sanding belt should run off, or if it is
not properly adjusted, your fingers could come in contact
with the moving sanding belt, resulting in possible serious
injury.
WARNING:
The sander is designed to be operated as shown with
both hands on the tool at all times for maximum control.
Never operate the tool overhead or inverted from the
proper operating position; serious personal injury may
result.

HELPFUL TIPS

 If the sanding belt slips or does not track while sanding,
you may be applying too much pressure. When this
occurs, remove the sander from the workpiece. If you
properly adjust the belt tracking, the sanding belt will
return to its normal and correct position on the drive roller
and front roller.
 Use a coarser sanding belt for heavy sanding, not heavy
pressure. The weight of the tool is sufficient to provide
adequate pressure at the correct location.
 The front roller of the sander is not designed for contour
sanding. Sanding on the front roller could cause
irregularity in the sanding belt tracking.
