SAFETY AND FAULTS
20
Partially unscrew the two middle levers on the
squeegee. Push the squeegee into the locating
lugs as illustrated and fully tighten the levers.
(pull the lever up to disingage it and make its
rotation free).
Push the coiled end of the squeegee hose fully
home onto the tubular spigot in the centre of the
squeegee.
Push the straight end of the squeegee hose onto
the tank inlet pipe which protrudes through a slot
in the lower rear panel.
Keyswitch/accelerator sequence:
This safety feature prevents the machine from
moving if the machine is accidentally switched on
with either forward or reverse function engaged
(due to machine fault or an operator error).
When this happens the leds on display panel
begin flashing.
Mosfet short circuit:
This safety feature prevents the machine from
moving if the machine is switched on with the the
part of the electronic print card controlling drive
power is in short circuit (in this case the machine
would move immediately at full speed). This
condition is signalled by the 3 voltmeter leds
which start flashing.
Overheating of the electronic print card
cooling vents:
This protection device of the electronic print card
prevents damage to the card itself during
prolonged use of the machine when one of its
functions is overloaded. In this condition the
machine automatically cuts off all its functions
which are then only restored when temperature
returns to normal value. This condition is signalled
by the lighting up in sequence of the 3 voltmeter
leds.
Micro switch:
Micro switch to shut off all the functions when the
tank is in the upright position.
