Maintenance And Inspection - Hitachi RP 35YB Handling Instructions Manual

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 filter
NOTE
Since a filter is a consumable, we recommend you
to prepare spares.
The cloth filter should simply be tapped even if it
is considerably clogged. (in the case of RP35YB)
Strong brushing will shorten its life.
Do not hurl a filter. (in the case of RP35YE) May
break its resin part.
In the case of RP35YB
A clogged filter will decrease the suction power
remarkably. Tap the inner side of the filter to drop
off dusts regularly.
In the case of RP35YE
Any dust caught between the water guard and the
filter will not be removed by the dust removing device.
Detach the connectors (2), loosen the wing bolts (3),
pull the water guard in the direction of the arrow to
disassemble it, and remove any dust. Reassemble by
following the above instructions in reverse order.
When connecting the connectors, push them in until
they click into place. (Fig. 24)
NOTE
Tighten the wing bolt securely when attaching the
water guard. Failure to do so may result in the
water guard falling off during use.
When removing the water guard, keep the wing
bolt, spring washer, washer and nut in a safe place
so that they do not get lost. Use them again to
assemble the water guard.
Before connecting the connectors (2), remove any
dust or dirt on the connecting parts. If dust or dirt
gets inside the connectors, it may prevent the parts
connecting properly.
If the filter is badly clogged, the filter cleaning
device cannot remove dusts enough and the suction
power will decline. Clean the filter by brushing and
compressed air blowing periodically. (at least once
per month) As shown in Fig. 21 and Fig. 22, the
filter should be subjected to brushing and
compressed air blowing in order to remove clogging
dusts with a view to recovery of suction power and
retention of performance. Hold the filter up to the
light and check that there are no tears or holes in
it. (Fig. 23)
Be sure to check the filter and the sensor shaft after
use.
If the filter or the sensor shaft is dirty, wash it with
water, being careful not to get any water on the
head as this may cause electric shock.
After washing, leave to dry out of direct sunlight.
If dirt has dried on the filter, brush it off gently.
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.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent of similarly
qualified persons in order to avoid a hazard.

power tools, the safety regulations and standards
prescribed in each country must be observed.
