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 on page 42
) 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
After operation of the tool has been completed, check that the following has been
performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,
When the tool is not in use, keep it stored in a dry place out of the reach of children.
8. Replacement of guard
After long-term use, the blade slot in the guard may widen and require replacement. If the
blade slot should widen, replace the guard with a new one (
Fig. 32 on page 56
). After
replacing, make a groove on it. Refer to “PRIOR TO CUTTING 1. Cutting a groove on the
guard” on page 44.
9. Lubrication
Lubricate the following sliding surfaces once a month to keep the power tool in good
operating condition for a long time.
Use of machine oil is recommended.
Oil supply points:
* Rotary portion of hinge
* Rotary portion of holder (A)
* Rotary portion of vise assembly
