PROBLEM | CAUSE |
| SOLUTION |
|
|
| |
Belts squealing during engine startup | Compressor belt needs tightening or | See Air Compressor Belt Replace- | |
| replacing | ment, page 9. | |
|
|
| |
Paint guns not spraying when empty | All of air supplied by air compressor is | Fill bead tank with beads or turn off air | |
bead tank is empty | rushing out of bead gun nozzles. In turn, | supply to bead tank. | |
| system air pressure cannot build |
|
|
| enough to trigger guns. This is normal. |
|
|
|
|
|
|
No system pressure | Compressor bypassing air continuously | 1. | Make sure silver switch on top of |
|
|
| unloader valve (148) is turned hori- |
|
|
| zontally. |
|
| 2. | Move silver switch on top of unloader |
|
|
| valve (148) up and down. This might |
|
|
| loosen a sticky valve. |
|
| 3. | Replace unloader valve (148). |
|
|
|
|
Beads not dispensing properly | Excessive water or moisture in bead | 1. | Only pressurize reflective materials |
| tank |
| when dispensing. Small air leaks at |
|
|
| gun nozzle or air fittings cause con- |
|
|
| tinuous moisture to be pumped into |
|
|
| tank. |
|
| 2. | For areas of extreme humidity a Ben- |
|
|
| dix air dryer or equivalent may be |
|
|
| installed in air line bead tank. Typi- |
|
|
| cally when beads are used continu- |
|
|
| ously, they do not spend enough |
|
|
| time in tank to collect enough mois- |
|
|
| ture to be a problem. Usually it is |
|
|
| continuous stencil painting for long |
|
|
| periods of time with little bead con- |
|
|
| sumption and high humidity that can |
|
|
| cause problems. |
|
|
|
|
Low system pressure | Excessive air leaks | 1. | Fix all air leaks before they become |
|
|
| a problem. Air leaks can eventually |
|
|
| starve system air supply. |
|
| 2. | Most air leaks occur at bead tank |
|
|
| outlet fitting. If fitting leaks air, com- |
|
|
| pletely remove it and use thread tape |
|
|
| and liquid thread sealant before rein- |
|
|
| stalling it. |
|
|
|
|
No beads dispensing | Beads have solidified | 1. | Never store RoadLazer with reflec- |
|
|
| tive materials in tank for long periods |
|
|
| of time. |
|
| 2. | Remove aluminum fitting from bot- |
|
|
| tom of tank. Flush out solidified |
|
|
| beads. |
|
| 3. | Use air hose or water hose to break |
|
|
| up and remove solidified beads from |
|
|
| tank. |
