MAINTENANCE AND INSPECTION

WARNING
Be sure to turn off the switch and pull out the battery before doing any inspection or maintenance.
1. Inspecting the blade
Continued use of a dull or damaged blade will
result in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive abrasion is noted.
CAUTION
If a dull saw blade is used, reactive force is
increased during cutting operation. Avoid the
use of the dull saw blade without repair.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosened screws is
extremely dangerous.
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. Lubrication
The bearings in this tool have been sufficiently
lubricated with quality lubricating oil, taking into
account the expected life of this tool under normal
operating conditions. As a result, no further
lubrication is necessary.
6. Disposal of the exhausted battery
WARNING
Do not dispose of the exhausted battery. The
battery must explode if it is incinerated. The battery
is recyclable. At the end of it's useful life, under
various state and local laws, it may be illegal to
dispose of this battery into the municipal waste
stream. Check with your local solid waste offi cials
for details in your area for recycling options or
proper disposal.
7. Storage
Storing in a place below 104°F (40°C) and out of the
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, signifi cantly
reducing battery usage time or rendering the
batteries incapable of holding a charge.
However, significantly 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.
8. 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.
9. Service parts list (Page 53)
CAUTION
Repair, modification and inspection of Hitachi
Power Tools must be carried out by a Hitachi
Authorized Service Center.
This Parts List will be helpful if presented with
the tool to the Hitachi Authorized Service Center
when requesting repair or other maintenance. In
the operation and maintenance of power tools,
the safety regulations and standards prescribed
in each country must be observed.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without
prior notice.
