HD Dust Collectors
Training
- Use all appropriate PPE
- Use only a heavy-duty cord
- Use as short a cord as possible
- When using the HD2 or HD3, you have the option of using a single or multiple motors for variable CFM
- When starting the machine with an empty bag, it will be sucked up into the machine. THIS IS NORMAL! As the bag fills with debris, it will be suspended underneath the filter container.
- Change out the bag once it has accumulated 20 – 30 lbs. for easy removal. The heavier it gets, the higher the risk of spillage. See our separate video for a demonstration of how to change the bag.
- When using the wand and floor tool, adjust the floor tool for maximum suction on the surface of the floor to ensure the removal of all debris lodged in the surface of the concrete surface
- NEVER attempt to clean cone filters or HEPA filters. Replace them as needed
- always wear a protective dust mask
- turn the machine off
- pull down approximately 18 inches of bag material
- attach a zip-tie close to the top of the debris
- install another zip-tie approximately 10 inches above the previous one
- cut the bag between these two zip ties freeing up the filled section of the bag for disposal
- when transferring the full bag, hold the bag from both ends to prevent spillage
With the machine running, pull up on the suction block (the black knob situated at the hose intake).
Depress the relief bar (located on the top of the machine) five times, at three-second intervals.
Push down on the suction block allowing the machine to run freely with clean filters
When using with machines that create a large volume of dust and debris, purge the filters at least every half hour or as indicated by the filter clog gauge on the side of the machine.
Troubleshooting
Possible solutions:
- Check the power cord
- Check the breaker panel
- Flip the power switch(es)
Possible solutions:
- Make sure the front wheels are unlocked
- Check for any damage to the rear wheels
Possible solutions:
- Make sure the suction block is not pulled up
- Check to make sure at least one motor is switched to the ON position
- Look for a clog, split, kink, or any other damage to the hose.
- Close the air-flow inhibitor
Possible solutions:
- Check all motor switches
- Inspect hoses for kinks, clogs, and slits
- Check your other surface-prep machine (grinder, shotblaster): the dust shroud and gaskets should have good contact with the surface of the floor
- Close the air-flow inhibitor
Probably!
Questions to ask…
- Check a few things first:
Dust skirt pushed down tight to the surface?
Suction isn’t inhibited by holes or kinks in the hose?
Filters are clean and clear? - Next… Is the debris staying ON the floor, or do you see clouds of fine dust in the air?
- If there is a lot of VISIBLE dust in the air, then something is wrong. See set-up and operation instructions to make sure you are using the equipment properly.
- If the chunky debris is staying ON the floor, and there is NO (or very minimal) visible dust in the air, then the vacuum is doing its job by removing the friable (and therefore, dangerous) dust from the air.
- You can USE those grindings to cut the concrete faster. But keep in mind!! The more grindings on the floor, the faster you will burn through your diamond tooling. Use your professional judgement to balance your own production rates and tooling costs!
- The larger grindings can be carefully swept with a SQUEEGEE (not a broom) and vacuumed with the floor wand or manually with a dust pan.
