Operation - Porter-Cable 505 Instruction Manual

OPERATING THE SWITCH
This tool is equipped with a trigger
switch (A) Fig. 5. A switch-locking
button (B) is located on the left side
of the handle. Start the motor by
depressing the trigger. Stop the motor
by releasing the trigger. To keep the
motor running without holding your
finger on the trigger, depress the
trigger, push in on the locking button
and release the trigger. To release the
locking button, depress the trigger
and release.
Make sure switch is off before inserting cord plug into power
circuit outlet.
STARTING TO WORK
This finishing sander has been designed for one- or two-hand operation, and
can easily be guided over the work surface. The normal weight of the machine
is sufficient for efficient sanding. Putting additional pressure on the machine only
slows down the speed of the pad, reduces the sanding efficiency, and puts an
additional burden on the motor. Also, additional pressure might cause the sander
to "jump". Always start the machine before placing it on the work surface. Once
it has started, ease it down on the work surface evenly and move it slowly back
and forth in wide, overlapping arcs. When you are through sanding, lift the sander
off of the work before stopping the motor.
