Getting Started
STEP 2. Filling the blast pot with abrasive
The DB800
®
is designed to hold:
• 30 gallons of clean water
• 300 lbs of abrasive (~50/70 mesh size)
• 42 oz of Rust Inhibitor
Connect Blast Hose Connect Twin Line
A NOTE TO BLASTER
Before blasting, it is recommended that user reads through
the entirety of this manual for proper operating procedures
and important maintenance instructions.
Always inspect machine, nozzles, hoses, and couplings
prior to blasting.
STEP 1. Connecting blast hose and twin line
Connect the blast hose to the pinch hose at the top of the
blast pot and insert the safety pin. Connect compressor
air hose to the air inlet and insert safety pin. The twin line
for your deadman controller must also be connected to the
control box on the back of the machine; red to red, green to
green.
STEP 3. Power up your compressor
Please refer to your compressor manufacturer’s manual
for operating instructions.
Before you start blasting, you will need to pressurize the
machine. Make sure the abrasive lever is unlocked, then
close the blow down valve, and open the air inlet valve.
When the machine pressurizes, you will see the abrasive
lever on the blast pot pop up.
Note: Open air inlet valve slowly to avoid sending
large amounts of compressed air into the machine
too quickly. This will cause unnecessary wear on the
system.
Note: A valve is in the open position when it is aligned
with the xture that it controls.
Note: The air inlet valve and blow down valve will always
be in opposite positions of each other.
Remove the ll cap by pulling the paddle up and turning the
cap counter-clockwise. Place the ll funnel in the opening
and pour in clean water. Then, pour in the amount of abrasive
that you need. If you are planning to use Rust Inhibitor, add it
to the blast pot now. Once complete, remove the funnel and
replace the ll cap. Everything will mix together during the
blasting process.
Note: Your machine will use any type of abrasive or cleaning
medium that sinks in water and is not water soluble.
