Cleaning out a clogged metering valve
Where used
Mach 500 · Mach 300 · Mach 200 · Mach 100
To clean out a clogged metering valve, do the following:
1. Turn off the abrasive hopper.
CAUTION!
Failure to off the abrasive hopper before you remove the metering valve
could cause abrasive to be expelled with the compressed air, causing injury.
2. Twist the knurled aluminum piece on the lower half of the metering valve clockwise, and then
remove the piece and allow the abrasive to empty out.
3. Remove any abrasive or moisture that is present on the components. Do not reuse the
abrasive!
4. Reassemble the metering valve. Make sure to install hand-tight only or else you risk cracking
the body if you overtighten it.
5. Turn on the abrasive hopper and resume operation.
