Dynabrade Downdraft Sanding Table

Keep Workplace Area Free of Contaminants While Sanding

Reorder No. D01•18

Operating Manual

Congratulations on the purchase of your new Dynabrade Downdraft Sanding Table!

Your sanding table should give you many years of service with just a few minutes of maintenance on a regular basis. The simple and robust
design of this machine is a unique feature which will allow a minimum of maintenance to keep it in excellent running condition. The motor(s)
in your table have sealed bearings and do not need grease. The blowers are direct drive units which have no belts to wear out. The blower
inlet cones are made from aluminum or fiberglass to prevent sparking, should the cone drag the blowers (very unlikely in normal use). As you
can see, a lot of consideration has gone into the manufacture of your new sanding table to insure that you have years of trouble-free service.
Your table has been designed with excess filter area (up to 70% more than some competitive units) in order to give better performance and
require cleaning less frequently.

Machine Operation And Useful Tips:

Downdraft tables are designed to filter out the fine dust generated while performing various jobs such as sanding with an orbital sander.
There is no machine to our knowledge that is 100% effective, but with a few simple pointers, you can enjoy a cleaner and much
healthier work area. We have listed below some useful tips to help you get the best results from your new machine.

A. Clean filters as needed to keep the machine performing at it’s highest level. Cleaning may be done by vacuuming the filters or by

shaking out the dust. In addition, for the shop that has a central dust system, you can easily build a box that the filters will fit in and hook
it up to the central system. You may then use an air hose to blow the dust out of the filters into the dust system. Whichever method you
choose, regularly cleaned filters are necessary for optimum performance.

B. When sanding, keep the part that you are sanding as close as possible to the top of the table. The downdraft table is designed to pull

dust away from your breathing zone. By keeping the work piece close to the top, the machine will capture more of the dust.

C. Never use an air hose to blow off the item being sanded. The use of a brush is better because it will not stir up the dust like an air hose.

D. Keep your machine running, even when you are not actively using it for sanding. The large volume of air it moves and filters w ill improve

the overall air quality in your shop area.

Important:

Before operating your downdraft table, please take a few minutes to read this booklet. Your new table comes wired to the starter switch
from our factory according to the voltage specifications ordered. Take a minute to double check the motor(s) and make sure they are
correctly wired to meet your voltage requirements. If you have purchased a three-phase unit, you will need to run conduit and wire to the
switch boxes or starters provided. Proper wiring that meets the requirement of all codes in your area is of the utmost importance, and should
be done by qualified electricians only.

Before starting your new table, you should check the following items to insure a safe start up.

A. Make sure all power is disconnected from the machine or locked out properly.

B. Raise the top and take out the upper filter media. Directly underneath is an expanded metal guard. Remove the guard (some models

will require removal of holding screws), and spin the blower wheel(s) by hand to ensure that there is no interference between the
blower and inlet cone. In rare cases, the inlet cone(s) may require adjustment to clear the wheel because of movement in shipping. To
adjust, loosen screws and adjust inlet cone position until it does not drag the blower. There should be approximately the same gap all
the way around the blower. After seeing that all is clear and the blower spins freely, reassemble in reverse order.

C. Check rotation of blowers. Blowers should be turning in a clockwise rotation looking down from the top. If rotation is backwards, this can

be corrected by changing the wiring configuration. Schematics are printed on the motors on single-phase units. Changing any two
phases of current reverses three-phase motors.

D. Check all the filter frame turn buttons to be sure all the frames are secure and in place.

E. Make sure the machine is leveled and your machine is now ready for operation.

F. Never lift top while machine is running!!!

G. Never service machine without first disconnecting power supply.
