6. Operation of mode selection switch, vacuum switch,
and filter cleaning switch (Fig. 10)
(1) Mode selection switch
By pushing "A" (Auto) this appliance can be operated
and stopped by the operation of the switch of the
power tool connected. By pushing "M" (Manual)
this appliance can be operated and stopped by the
operation of its switch.
(2) Vacuum switch
By pushing "ON" the appliance will be operated.
By returning the switch to "OFF" the appliance will
stop. When the mode selection switch is in "M"
(Manual) the appliance will operate and stop by the
operation of the vacuum switch.
(3) Filter cleaning switch [in the case of RP35YE]
NOTE
If, during running of the filter cleaning device, the
vacuum switch is put in "ON" or the operation
interlocked with the power tool is started, the operation
of the filter cleaning device will stop. In the following
cases, the filter cleaning device does not operate:
When the vacuum switch is in "OFF".
Until the motor stops by putting the vacuum
switch in "OFF".
When more than 15 minutes have passed after
putting the vacuum switch in "OFF".
(Once the filter cleaning device is stopped by putting
the vacuum switch in "ON", it can be operated.)
When the plug is inserted.
(Once the filter cleaning device is stopped by putting
the vacuum switch in "ON" it can be operated.)
Even if the filter cleaning switch is not pressed,
since this machine always monitors its suction
power, when the suction power declines to some
extent, the filter cleaning device will operate
automatically and the suction power will recover.
If the vacuum switch is in "OFF" and the filter
cleaning switch is pressed, the filter cleaning device
will operate for several seconds, allowing dusts to
be dropped from the filter.
(4) Procedure of operation of each switch
(a) When using the appliance with a power tool
interlocked
1 Push "A" (Auto) of the mode selection switch.
2 Push "ON" of the vacuum switch.
3 By operation of the switch of the connected power
tool, this appliance also operates and stops
interlockedly. In addition, in order to suck up the
dusts remaining in the hose, the appliance runs for
several seconds even after turning off the switch
of the power tool, and then the appliance stops.
(b) When using the appliance as a cleaner
1 Push "M" (Manual) of the mode selection switch.
2 If "ON" of the vacuum switch is pushed, the
appliance will operate. To stop it, return the switch
to "OFF".
In the case that the filter cleaning device will be
operated automatically, push "A" (Auto) of the mode
selection switch.
7. Filter cleaning
WARNING
Be sure to turn off the vacuum switch and disconnect
the plug from the power receptacle.
CAUTION
If the tank is filled with dusts, the suction power
declines. Dump dusts as early as possible when
they reach the half of the tank height.
In the case of RP35YB
When the suction power declines during use, remove
dusts in the following procedure:
(1) Remove the clamp and detach the head. For the
procedure, refer to "8. Dump dusts".
(2) Remove attached dusts by striking the inner side
of the filter several times with the filter mounted
in the tank. The suction power will be recovered.
(3) Attach the head and the clamp in the original
position. For the method of attachment, refer to
"8. Dump dusts".
In the case of RP35YE
This appliance is equipped with a device which
automatically filter cleaning from the filter when the
suction power declines to some extent.
NOTE
Since the filter cleaning device operates when the
suction power declines to some extent, it also
operates in the following cases:
When the suction mouth at the tip of the hose is
closed.
When the hose is clogged with foreign matter.
(1) When the suction power of the appliance declines
to some extent during use, its filter cleaning device
will operate automatically and its suction power will
be recovered as follows:
(a) When using the appliance as a cleaner
After the motor is stopped by putting the mode
selection switch in "A" (Auto) the filter cleaning
device operates for several seconds.
(b) When using the appliance with a power tool
connected
Put the switch of the power tool in "OFF" and run
the appliance in full operation for several seconds.
Then, after the motor is stopped, the filter cleaning
device operates for several seconds. Depending on
the power tool connected and the thickness of the
attachment adapter at the tip of the hose, the filter
cleaning device may operate whenever the switch
of the power tool is put in "OFF". This is not a
failure, however.
(2) When removing dusts from the filter each time,
after putting the vacuum switch in "ON", push the
filter cleaning switch. (Fig. 10) Whenever it is pushed,
the filter cleaning device will operate for several
seconds. Even if the filter cleaning switch is pushed,
the filter cleaning device may not operate. Refer to
"6. (3) Filter cleaning switch".
(3) If the filter cleaning device is repeatedly operated
and the suction power is not recovered, the tank
is almost filled with dusts. Dump dusts in the tank.
8. Dump dusts
WARNING
Be sure to turn off the vacuum switch and disconnect
the plug from the power receptacle.
In the case of RP35YE after the operation of the filter
cleaning device, be sure to turn off the vacuum switch
and disconnect the plug from the power receptacle.
CAUTION
Do not impact the tank, the filter, or the head.
Otherwise they will be deformed or damaged.
Although it is based on the amount of suction of
dusts and liquids, dump dusts and liquids in the
