4.4 Adjusting the spray pattern (HB 700 Spray only)
The spray pattern is altered by adjusting the spray air.
Set the optimum spray pattern by turning the spray-air choke (14) in the protective sleeve
(13):
• Turning it clockwise decreases the spray-air pressure.
• Turning it anticlockwise increases the spray-air pressure.
4.5 Automatic temperature reduction (ACE)
Unnecessary thermal loading of the melt should be avoided. The device therefore swit-
ches to standby mode at reduced temperature when the trigger has not been actuated for
a considerable time (paused operation).
In the condition as supplied the temperature is reduced by 72 F / 40°C after 30 minutes’
paused operation. The programming of the relevant parameters is described in Section
3.3.2.
Briefly actuate the trigger or the Up or Down button to quit standby mode. The device
immediately reheats to working temperature.
4.6 Switching off
1. Press the Start/Stop button (6) for approx. 1 s until the display goes out.
2. Adjust the operating pressure down to “0” with the pressure regulator (3) or disconnect
the compressed-air supply.
5 What if...
This Section summarises the status and error messages and provides help in eliminating
errors.
If malfunctions occur please check first
• hat the power supply and
• compressed-air supply are functioning correctly, and
• whether there is mechanical damage to the device or supply lines (power supply, com-
pressed air).
If you find any mechanical damage, the device may in no circumstances be started up
again. Have it checked and repaired by a qualified service agent.
