plug has been disconnected from the receptacle before
performing any maintenance or inspection of this tool.
Report to quali
fi
ed person as soon as possible, if you
discover the fault of machine including guards or blade
saw.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the
fi
rst
sign of deterioration or damage.
A damaged saw blade can cause personal injury and
a worn saw blade can cause ine
ff
ective operation and
possible overload to the motor.
CAUTION
Never use a dull saw blade. When a saw blade is dull,
its resistance to the hand pressure applied by the tool
handle tends to increase, making it unsafe to operate the
power tool.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, re-tighten them immediately. Failure to do so
could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 34)
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 ensure that they slide freely within the brush
holders.
4. Replacing a carbon brushes (Fig. 34)
Disassemble the brush cap with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (
Fig.
6
) to assure that it is in good condition and that it moves
smoothly.
Never use the tool unless the lower guard operates
properly and it is in good mechanical condition.
7. Storage

that the following has been performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,

out of the reach of children.
8. Lubrication

Oil supply points:
* Rotary portion of hinge
* Rotary portion of holder (A)
* Rotary portion of vise assembly
9. Cleaning

from the surface of the power tool with a damp, soapy
cloth. To avoid a malfunction of the motor, protect it from
contact with oil or water.
