Maintenance And Inspection - Hitachi CE 16SA Handling Instructions Manual

MAINTENANCE AND INSPECTION

1. Inspecting the blade
Using a worn or chipped blade will put an excessive
burden on the motor and affect work performance.
Therefore, always use a well-cutting blade.
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. Inspecting the carbon brushes (Fig. 6)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon brush
No. shown in the figure when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
5. Replacing carbon brushes
Disassemble the brush cap with a screwdriver. The
carbon brush can then be easily removed.

Uncertainty K = 2.3 m/s
WARNING
The vibration emission value during actual use of the
power tool can differ from the declared value
depending on the ways in which the tool is used.
To identify the safety measures to protect the operator
that are based on an estimation of exposure in the
actual conditions of use (taking account of all parts of
the operating cycle such as the times when the tool is
switched off and when it is running idle in addition to
the trigger time).
