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 rmly and pull out the battery.
NOTE
After charging, pull out batteries from the charger 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,
rst let the battery cool, then start charging.
When the pilot lamp 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 con 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 speci c grease is used with this machine, therefore,
the normal performance of the machine may be badly
a ected by use of di erent grease. Please be sure to let
one of our service centers to undertake replacement of
the grease.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to turned o the switch and remove the battery
before maintenance and inspection.
1. Inspecting the tool
Since use of as dull tool will degrade e ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
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. Cleaning on the outside
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.
5. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
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.
NOTE
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, signi cantly
reducing battery usage time or rendering the batteries
incapable of holding a charge.
However, signi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
