Figure 2-2: DirectFlo Reference Sheet
Figure 2-2 is an illustration of the Reference Sheet that comes with your DirectFlo. It
contains important information you can use to get the most out of your investment. Keep
it nearby and refer to it often. However, it cannot substitute for the comprehensive data
found in this manual. Prior to setting up and operating your DirectFlo, the operator and
the department supervisor should carefully review this entire manual.
QUICK START INSTRUCTIONS
You may use this tip sheet to quickly get your DirectFlo set up and ready to operate, and as a ready reference for common questions regarding the
operation of the DirectFlo. Keep it nearby and refer to it often. For complete details on the DirectFlo, Comco strongly urg es you to read the manual
completely.
The money invested in this equipment justifies this time.
SAFETY PRECAUTIONS
1
The DirectFlo operates using high voltage electrical power and high pressure air. Proper set-up, operation, and maintenance is
essential for safe use. Read the Safety Precautions in the introduction of the manual before using your DirectFlo.
2
You must use proper dust collection and a WorkStation in conjunction with the equipment.
3
Never point the nozzle at exposed skin, eyes, or face.
4
Always be sure that the nozzle is held firmly before activating the foot pedal.
5
Add abrasive to the tank through the “Quick-fill” valve using the funnel provided in the accessory kit. Wipe the flapper and O-ring with
a soft dry towel after abrasive powder is added with t
he funnel to get an airtight seal. Don’t overfill the tank. 1 1/4” from the top is
maximum. Make sure the tank cover is tightened snugly.
To change abrasives, see instructions in Section 3.
DirectFlo SETUP TIPS
1
Verify that the hose from the dust coll
ector is connected to the 4” collar on the back panel of the WorkStation. For optimum dust collection,
the hose should be as short as possible.
2
Position the DirectFlo on top or along side of the WorkStation.
3
Verify the DirectFlo is connected to a dry air supply of 80 - 140 PSIG. Bottled CO
2
or nitrogen is recommended if dry air from a compressor
is not available. See page 2-6 of the manual for instructions.
Note: If the pinches on the rear panel do not close when the machine is turned on, the air supply pressure is probably too low.
4
Pass the handpiece through the small port on the side of the WorkStation. The “Tank Vent” hose should be pushed 2-3” through a grommet on
the backside of the WorkStation.
5
Add abrasive to the tank through the “Quick-fill” valve using the funnel provided in the accessory lot. Wipe the flapper and O-ring with a soft dry
towel after abrasive powder is added with the funnel to get an airtight seal. Don’t overfill the tank. 1 1/4” from top is the maximum. Make sure the
tank cover is tightened snugly. To change abrasives, see instructions in Section 3 of the manual.
6
Turn on the facility dust collector.
7
Turn the DirectFlo Power ON. Adjust pressure regulator to desired blasting pressure (see Section 3 of the manual for details).
8
Place the item(s) to be blasted into the WorkStation. Hold the handpiece firmly and direct the nozzle toward the area to be blasted. Never point
the nozzle toward the glass window. Begin blasting by depressing the footswitch.
9
The speed and type of cut will vary with the distance and angle of the nozzle. See section 3 for concise information.
10
To shut down the system, turn the Power switch to OFF and press the Pressure Release valve. Allow 30 seconds for the tank to de-pressurize.
Verify that the pressure gage reads zero.
NOTE: There is no need to depressurize after each use. Frequent shutdown causes excessive wear and will waste abrasive. Th e DirectFlo is
designed to remain pressurized for an entire work shift.
