Maintenance And Inspection - Hitachi RP 150YB Bedienungsanleitung

English
(a) When using the appliance as a cleaner
After the motor is stopped by putting the mode selection
switch in "A" (Auto) the fi lter 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 fi lter 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 fi lter cleaning device
may operate whenever the switch of the power tool is put
in "OFF". This is not a failure, however.
(2) If the fi lter cleaning device is repeatedly operated and
the suction power is not recovered, the tank is almost
fi lled 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.
CAUTION
○ Do not impact the tank, the fi lter, 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 tank at least
once a day and keep the appliance, the fi lter, etc. clean.
Otherwise suction power fall, motor failure, bad smell or
rusting may be caused.
○ Do not hold the clamps when you dump dusts in the tank.
Otherwise the clamps may be damaged.
NOTE
Do not tilt the tank with accessories (Pipe, Master nozzle,
etc.) inserted in the base or in the tank. Otherwise any
part may be damaged.
WARNING
If the appliance is pushed on its side while the tank
contains liquid, the liquid will get inside the motor or
switch region, causing an electric shock or motor failure.
(1) Remove the clamps (2 pieces) and raise the handle of
the head. (Fig. 9)
(2) Lightly striking the inner side of the fi lter several times,
remove dusts attached to the fi lter.
(3) Tilt the tank and dump dusts. (Fig. 10, 11)
(4) Attach the fi lter, the fi lter cage, the head, and the clamp
in the initial positions.
9. Transportation and storage
(1) How to use the handle
When carrying or moving the appliance, hold the handle
of the head part as shown in the Fig. 12. When you do
not use the handle, put it in the head part.
(2) Fixation and release of the caster
By lowering the lever of the caster with the brake, the
rotation of the wheel is fi xed. When releasing the fi xed
wheel, raise the lever. (Fig. 13) When moving with
the appliance on a vehicle, fi x the caster to retain the
appliance. However, when you move the appliance,
check that the caster is released, or the caster will be
damaged.
(3) When the appliance is stored
When you want to interrupt cleaning for a moment, you
can hook the pipe holder of the pipe. The appliance
can be then stored. The cord can also be bundled and
hooked. (Fig. 14)
10. How to attach the paper fi lter (Optional)
WARNING
○ Be sure to turn off the appliance and remove the plug
from the electric outlet.
○ When using a paper fi lter, use it in combination with the
standard cloth fi lter.
If the paper fi lter gets torn, dust may get inside the motor,
causing abnormal noise or fi re due to overheating.
CAUTION
When using a paper fi lter, avoid sucking in liquids such
as water or wet dust, as this may lead to tearing of the
fi lter.
(1) Open the paper fi lter horizontally so that the suction hole
in the paper fi lter is over the top of the tank. (Fig. 15)
(2) Before attaching the fi lter to the appliance, bend the two
folds in the cardboard approx. 90° in the direction of the
arrow. (Fig. 16)
(3) Match the suction hole in the paper fi lter with the suction
opening of the appliance. Insert the fi lter in the direction
of the arrow as shown in the illustration, so that the
cardboard of the paper fi lter goes past the stopper on
the suction opening. (Fig. 17)
FLOAT MECHANISM
This appliance is equipped with a fl oat mechanism to prevent
water from entering in the motor when it sucks in more than
a specifi c quantity of water. When the fl oat operates not to
suck in water, turn off the switch promptly and throw away
water in the tank.
WARNING
○ With the fl oat working, do not continue operation.
Otherwise the temperature of the motor may rise
abnormally causing troubles such as deformation of
parts or motor burnout.
○ Avoid sucking in foaming liquid such as detergent or
foams. Before the fl oat works, foams may spurt from the
air outlet. If you continue to use the appliance as it is, it
will lead to electric shock or failure.

MAINTENANCE AND INSPECTION

WARNING
○ For inspection and maintenance, be sure to turn off the
vacuum switch and disconnect the plug from the power
receptacle.
○ Do not work with wet hands. May cause electric shock
or injuries.
1. Maintenance of fi lter
NOTE
○ Since a fi lter is a consumable, we recommend you to
prepare spares.
○ The cloth fi lter should simply be tapped even if it is
considerably clogged. Strong brushing will shorten its
life.
○ Do not hurl a fi lter. May break its resin part.
A clogged fi lter will decrease the suction power
remarkably. Tap the inner side of the fi lter to drop off
dusts regularly.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Check for Dust
Dust may be removed with a soft cloth or a cloth
dampened with soapy water. Do not use bleach,
chlorine, gasoline or thinner, for they may damage the
plastics.
5. Service and repairs
All quality power tools will eventually require servicing
or replacement of parts because of wear from normal
use. To assure that only authorized replacement parts
will be used, all service and repairs must be performed
by a HITACHI AUTHORIZED SERVICE CENTER,
ONLY.
