PRESSURE TESTING & UNLOADER ADJUSTING .... ELECTRIC POWERED BLASTERS
1,200 PSI ELECTRIC MOTOR COLD WATER BLASTERS
1.
Connect machine to mains pressure water supply, ensuring
that water is passing freely through the pump at the correct
flow rate for specified pump by holding the gun trigger open.
2.
Ensure that nozzle fitted in lance is the correct size (BB100
nozzle should be 035). Replace nozzle if worn or damaged.
3.
Ensure machine is unplugged and check inside the on/off
switch to ensure contactor inside is set to 13 amps.
4.
Fit pressure gauge kit between high pressure outlet of pump
and high pressure hose.
5.
Plug in blaster and turn on with the trigger on the gun
pressed.
6.
With the unit running and the trigger on the gun pressed,
measure amps on power supply cable to make sure amps
are running at acceptable levels. (No more than 12.5 amps,
ideally set at 12.2 amps). Amp meter must be connected to
the active (brown) wire.
7.
The BB100 should achieve 1200- 1250 psi when set to 12.2
amps. To change the pressure or the amperage drawn,
adjust the unloader using the allen key while the gun trigger
is pulled.
It is more important to set the machine to the correct
amperage rather than pressure. Check amp meter to ensure
electrical characteristics are within acceptable parameters.
Apply Loctite 243 Super Thread to grub screw of unloader
and mark with paint.
