7. AUTOMATIC ADJUSTMENT
OF OPERATING POWER (IN-
VERTER CONTROL)
Microcomputer-based inverter control is enabled
on this machine in order to ensure the maximum
utilization of the discharging performance. Ad-
justment of the operating power is automatically
continued until the pressure in the machine tank
reaches the maximum level being set for the cur-
rently set mode. Operating sounds may change
when the operating power is switched, but you
do not have to worry about them. Changes in the
sounds are not due to a failure.
•
The pressure level at which the output change-
over is activated varies depending on the ca-
pacity of the main power supply, type of
extension cord used and parallel use of other
electric equipment. If the voltage is excessively
low, extra time will be required for the filling.
•
If the fill time is longer than usual or when the
pressure does not increase, change the cur-
rent connection to the power supply (reconnect
to the main power supply) or stop the joint use
of the power supply with a power tool.
•
When capacity of the main power is 110 V or
less, or when it is jointly used with another
power tool, a radical voltage drop results, in-
ducing startup failure.
•
The circuit breaker of the power supply may be
activated if the total current consumption re-
sulting from the parallel use with another pow-
er tool exceeds the current capacity of the
circuit breaker.
In such a case, do not use the same power
supply to power any other power tools.
8. IN ORDER TO MAINTAIN
PERFORMANCE
1. Drain water from the machine.
After the work is finished, turn the handle of
the pressure-reduction valve clockwise and
open the drain cock gradually to drain the
compressed air and water in the air tank until
the pressure gauge pointer of the pressure-
reduction valve points to 0.
•
Not draining the water will result in the
inside of the air tank becoming moldy,
potentially leading to a failure.
2. The Maintenance LED lights up or flash-
es.
Operating hours of this machine are meas-
ured with a microcomputer. The MAINTE-
NANCE LED lights up as the machine
operating hours reaches 1000 hours. If the
Maintenance LED lights up, send the ma-
chine to your dealer or an authorized service
facility for inspection.
