MAINTENANCE AND INSPECTION

1. Inspecting the saw blade
Since use of as dull saw blade will degrade effi ciency
and cause possible motor malfunction, sharpen or
replace the saw blade 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. Inspecting the carbon brushes (Fig. 22)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush
No. ⓐ shown in the fi gure when it becomes worn to or
near the "wear limit" ⓑ. In addition, always keep carbon
brushes clean and ensue that they slide freely within the
brush holders.
CAUTION
When replacing the new carbon brushes, always use
genuine HiKOKI carbon brushes with the number
specifi ed in the drawing.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. Motor unit maintenance
The motor winding is an important part of this tool. Avoid
damaging and be careful to avoid contact with cleaning
oil or water.
After 50 hours of use, clean the motor by blowing into the
ventilation holes of the motor housing with dry air from an
air gun or other tool (Fig. 25).
Dust or particle accumulation in the motor can result in
damage.
6. Inspecting and maintaining the lower guard
Always make sure that the lower guard moves smoothly.
In the event of any malfunction, immediately repair the
lower guard.
For cleaning and maintenance, use an air gun or other
tool to blow clean the space between the lower guard
and gear cover as well as the rotation part of the lower
guard with dry air (Fig. 25).
Doing so is eff ective for the emission of chips or other
particles.
Accumulation of chips or other particles around the lower
guard may result in malfunction or damage.
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun or other tool to clean the lower guard,
ventilation holes or other parts of the product.

7. Cleaning the inside of the saw cover
Regularly check and clean to make sure that sawdust
and other residue do not collect inside of the saw cover.
Always remove the saw blade when checking and
cleaning.
8. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
9. 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.
10. Storage
Storing in a place below 40°C and out of the reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) 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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the HiKOKI
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).
