MAINTENANCE AND INSPECTION

WARNING
To avoid an accident or personal injury, always
confirm the trigger switch is turned OFF and that the
power plug has been disconnected from the
receptacle before performing any maintenance or
inspection of this tool.
Report to qualified 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
first sign of deterioration or damage.
A damaged saw blade can cause personal injury and
a worn saw blade can cause ineffective 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. 37)
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 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.
4. Replacing a carbon brushes
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.
4) 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.
38). After replacing, make a groove on it. Refer to "4.
Cutting a groove on the guard" on page 19.
9. Replacement of Poly-V-Belt
The power of the motor is transmitted to the saw blade by
a Poly-V-Belt. When the Poly-V-Belt is broken or
damaged, remove the belt cover by loosening the four 5
mm screws (Fig. 2) and replace the damaged one with
the new one.
When connecting the belt on pulleys, first connect 2 or
3 teeth of Poly-V-Belt to the grooves of the pulley
(A) and pulley (B). Then turning the pulley (A) and
pulley (B), connect all 13 teeth of the belt to the pulleys
(Fig. 39).
10. 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
11. Cleaning
Periodically remove chips and other waste material 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.
If the laser line becomes invisible due to chips and the like
adhered onto the window of the laser marker's light-
emitting section, wipe and clean the window with a dry
cloth or a soft cloth moistened with soapy water, etc.
