(3) Lift the safety cover and mount the saw blade.
WARNING: When mounting the saw blade, confirm that the rotation indicator mark on the saw
blade and the rotation direction of the side cover (L) (see Fig. 1) are properly matched.
(4) Thoroughly clean washer (C) and the bolt, and install them onto the saw blade spindle.
(5) Press in the spindle lock and tighten the bolt by turning it to the left by 10mm box wrench as
indicated in Fig. 42-b.
CAUTION: * A dust guide is installed inside behind the side cover (L).
When removing or installing the saw blade, do not make contact with the dust
guide. Contact may break or chip saw blade tips.
* Confirm that the spindle lock has returned to the retract position after installing or
removing the saw blade.
* Tighten the bolt so it does not come loose during operation.
Confirm the bolt has been properly tightened before the power tool is started.
2. Dismounting the saw blade
Dismount the saw blade by reversing the mounting procedures described in paragraph 1 above.
The saw blade can easily be removed after lifting the safety cover.
CAUTION: Never attempt to install saw blades larger than 10" (255mm) in diameter.
Always install saw blades that are 10" (255mm) in diameter or less.
OVERLOAD PROTECTIVE DEVICE FOR POLY-V-BELT
The power of the motor is transmitted to the saw blade by a Poly-V-Belt. When the Poly-V-Belt becomes
overloaded, the overload protective device cuts off the current to stop the motor.
In this case turn the switch off immediately and raise the handle to its initial position. Then turn the switch
on and after running the tool for 20 seconds without a load for cooling of the motor. Then start the cutting
operation. The Poly-V-Belt or the motor will be damaged if the overload protective device turns off frequently.
CAUTION: When the overload protective device stops the motor, the motor will start by turning the
switch on after turning it off. When turning the switch on, make sure that the saw blade
is not halfway in the material.
MAINTENANCE AND INSPECTION
WARNING:To avoid an accident or personal injury, always confirm that the trigger switch is turned
OFF and the power plug has been disconnected from the receptacle before performing
any maintenance or inspection of this tool.
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. Adjusting a loose slide pipe
After extended use of the power tool, the slide pipe (A) and the
bushing can become loose due to vibration. Never operate the tool
if any components are loose to avoid personal injury.
(1) Loosen the 8mm nut and tighten the four 8mm hexagon socket
set screws until the power tool operates smoothly without
looseness.
(2)
Properly tighten the 8mm nut after completing these adjustment.
