Sioux Tools 697 - Manual

1
CAUTION
Do not at any time attempt to operate this tool without shroud and pad in place.
OPERATION
The sander is designed to operate on 90 p.s.i. air pressure. An air regulator is recommended if pressures are higher than
90 p.s.i. A filter is strongly recommended to provide clean air for long life of the sander.
Lubricate the sander by adding 8-10 drops of air motor oil into the air inlet each day before using.
HOSE AND HOSE CONNECTIONS
Hoses should not be smaller than 3/8" I.D. with 1/4" pipe thread fittings.
LUBRICATION
As mentioned above, 8-10 drops of Sioux air motor oil, Cat. No. 288, should be added to the air intake before using each
day. This will help protect the motor parts from rusting due to water in the air lines and also lubricate the parts for longer
life. Caution should be taken not to add too much oil as it will blow through the tool and may get on the surface being
sanded. An air line oiler will increase the life of the tool. The setting should be about 1 drop of oil per 1-2 minutes of use.
SPEED CONTROL AND SHUT OFF
A speed control and air shut off is located on the bottom of the housing. This
control is adjusted as shown in the diagram. This is to control the speed of
the tool for various sanding operations and to control excessive air pressure.
The control is also used to shut off the air to the tool to safely change sand
paper on the pad.
COUNTER BALANCE
The units are equipped with different counterweights to decrease the vibra-
tion. Following is a chart of pad size and counterweight.

LOSS OF POWER & SPEED
The air motor is probably dirty and sticky. Flush out by adding very light weight oil to the air intake and run unit. Do this
several times until it runs properly. Then add 8-10 drops of Sioux air motor oil, Cat. No. 288, in the air intake and run tool to
lubricate.
WARNING
Continued exposure to vibration may cause injury to your hands or arms.
