NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
After charging, pull out batteries from the charger fi rst,
and then keep the batteries properly.
CAUTION
○ If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of the charger lights up green. In such a case,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects in
the charger's battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○ Since the built-in micro computer takes about
3 seconds to confi rm that the battery being charged
with UC36YRSL is taken out, wait for a minimum of 3
seconds before reinserting it to continue charging. If the
battery is reinserted within 3 seconds, the battery may
not be properly charged.

LUBRICATION
Low viscosity grease is applied to this rotary hammer so
that it can be used for a long period without replacing the
grease. Please contact the nearest service center for grease
replacement when any grease is leaking form loosened
screw.
Further use of the rotary hammer despite the grease
shortage causes damage to reduce the service life.
CAUTION
A specifi c grease is used with this machine, therefore,
the normal performance of the machine may be badly
aff ected by use of diff erent grease. Please be sure to let
one of our service centers to undertake replacement of
the grease.

Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modifi ed (such as
disassembly and replacement of cells or other internal
parts).
GUARANTEE
We guarantee Hitachi Power Tools in accordance with
statutory/country specifi c regulation. This guarantee does
not cover defects or damage due to misuse, abuse, or
normal wear and tear. In case of complaint, please send
the Power Tool, undismantled, with the GUARANTEE
CERTIFICATE found at the end of this Handling instruction,
to a Hitachi Authorized Service Center.

Be sure to turned off the switch and remove the battery
before maintenance and inspection.
Since use of as dull tool will degrade effi ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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.
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.
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge
may result in performance deterioration, signifi cantly
reducing battery usage time or rendering the batteries
incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
