More Information

There is a group working on dust collection needs, performance and recommendations. we started in October 2018 as interim information is available we will update this wikipage and wherever necessary


August 2019--The core team (led by Zack Sasnow and a few others) are in the process of assembling the Grizzly DC. Need to lift the power head and put the cyclone and filters under it. Then comes building the ductwork that we measured and designed. And connecting the main tools. Erik is designing our tool racks and benches around that. We hope to be totally tidy in a month or two. ... Being an old wreck, I assist in any way that I can without lifting toting or straining. --gary

Yellow Strobe Light means the Dust Collector is Full

The yellow strobe light in the woodshop is connected to a bin sensor that checks if the bin for the dust collector is full. If the strobe is blinking, stop what you are doing and go check the dust collector and planer bins. One of 2 things is happening: 1. The bin is full and YOU should empty it. Do not hesitate to rope anyone else in the woodshop to help you figure out how to do this task, lift heavy things, move materials, whatever. Also check the dust bin by the planer is not full. 2. The bin sensor is dirty. Clean it (needs instructions).

Emptying the Dust Collector

There are currently 2 dust bins: one next to the planer, and one under the dust collector cyclone.

When the bin is full

(Dust collector drum) Remove the drum at the from the cabinet by twisting the bayonette lock securing the cylone hose to the bin. (Both drums) unlock the steel spring strap and pop the lid off the drum. Tie the bag off in the bin. Drag the bin out to the dumpster and flip the whole bin in the dumpster. Do not hesitate to get someone to help you do this task, everyone should be helping keep the shops clean! There are dollies that float around the shop and may be useful in moving the drum.

Replacing the bag

Look for some heavy duty 55 gallon bags (location?). Place the bag to the rim of the dust bin. To keep the bag from getting sucked into the system place a piece of scrap lumber from the trash/dumpster that will fit flat at the bottom of the bin. Poke a hole thumb-sized hole in the bag a few inches from the top of the rim of the drum (if the hole is too high the drum lid will cap the hole). This lets out the air between the bin and the bag, DO IT.

Reasons for bags

All dust collection bins should have a plastic bag inside of them. The bag keeps the saw dust from blowing around outside and into your lungs; both miserable experiences. The trash collectors do not want loose wood chips in a dumpster, as it spills out through the gap in their truck when they flip the dumpster and they have to shovel it out of the alley. And everyone knows you don't mess with the trash collectors....

Manometer & Troubleshooting Filter/Suction Problems

A manometer has been installed on the output elbow of the dust collector. This manometer measures positive static pressure from the exhaust of the impeller due to the impedance of the filter. Static pressure with a clean filter during regular usage should not be more than 2" WC (water column is the difference, in inches, between the height of the water level in either leg of the tube of water).

The filter is blocked when the pressure is higher than 2" WC, and needs to be cleaned. If above 2" WC, overall system suction is reduced and the dust collector will not collect sawdust from the rest of the system appropriately, is a health hazard, and gets fine dust over everything.

How To

Turn it On/Off

Use the switch labelled as such on the wall of the furnace room by the ShopBot.
There is also a wireless remote. It's yellow and is usually near the ShopBot. The SawStop has a switch box as well.

Measure Filter Back Pressure

The clear plastic tube mounted near the filter stack is a manometer. When the collector is running, the distance between the left and right columns of the manometer should be two inches or less. If it exceeds this, flow through the filter will be reduced and it must be cleaned. When the filter is clean, the back pressure will be less than 1.25".

Manometer when the dust collector needs emptying. This is way more than the 1.25" backpressure that's acceptable.

Clean the filter

For extra safety, you can turn off the main switch at the top of the rack to be sure the collector won't start up while you're working on it. You can also just take the remote and set the Sawstop's iVac rocker switch to off. After the collector fan has stopped, remove the white plastic cap on the bin at the base of the filter stack. Scoop out the dust with your hand and into a bucket. This dust will be very fine - try not to breath it. Don't use a vacuum to clean the bin. The fine dust will go through most vacuum filters.

Use a combination of tapping and compressed air to dislodge dust from the filter pleats. You can tap with your hands or a plastic mallet on the outside of the filter. Don't get too crazy or you will dent the filter. Tap all around and the whole length. Two or three minutes of tapping will probably be enough unless the filter is really dirty. Compressed air from the hose reel above the assembly table can also be used. Spray the air all around the filter, keeping the nozzle an inch away from the mesh of the filter. Closer than that or using > 90 psi air pressure can damage the filter material. Replace the white cap and turn on the filter. IF the pressure is 1.25" or less you're done.

In the image at left, the bottom clear part should have nothing in it, especially not wood chips.

Hey, it won't turn off!

As of 5-26-15 this has occurred twice. Toggling the switch on the control box seems to get it working. Please notify the mail list if this happens.


The Ivac switch box that is located on the SawStop has a three position switch. Auto/Off/On. If it is in the on position the the dust collector cannot be turned off by the remote control or the wall switch. If the dust collector is running, switching to the off position is subject to the same off time delay (7 seconds as of 5/26/15) as the automatic setting or remote control off.
Make sure the Sawstop isn't running then make sure the switch is set to auto or off, wait 7 seconds. Still running? Try the wall switch by the ShopBot. Still running? Set the switch on the Ivac control box (above the DC) to off. Notify the mailing list.

Empty It

Follow the instructions printed on stickers on the lid of the waste bin.

Use checklist

PS1 is experimenting with the use of checklists to encourage the safe use and proper care of tools in the workspace. The latest version of the checklists for this tool is stored as a Google Doc that can be edited by anyone. If you make changes, update the effective date at the bottom of the document. Print a new copy, and replace the old one.

Wiring

The wall switch near the boiler room is SPDT. It is wired to alternately energize either the magnetic starter directly or energize the outlet that the IVac control box is plugged into. Both are located on the wall above the collector.

The magnetic starter is wired in an unconventional manner. It does not provide protection from over heating or protection from motor automatic restart following power loss and restoration. In addition only 2 of the 3 fuse positions have fuses, the third is bypassed.

The Dust Monitor

Due to excess dust being a health issue, there is a Dust Monitoring project that should be pursued.
