APPLICATIONS
○ Cutting sheet metal, concrete, cinder blocks,
reinforcing rods, concrete wire mesh, corrugated
fl oor and ceiling forms, etc.
PRIOR TO OPERATION
1.
Power source
Ensure that the power source to be utilized conforms
to the power source requirements specified on the
product nameplate.
2.
Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch is
in the ON position, the power tool will start operating
immediately and can cause serious injury.
3.
Extension cord
When the work area is far away from the power
source, use an extension cord of suffi cient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
WARNING
D a m a g e d c o r d m u s t b e
replaced or repaired.
4.
Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause
overheating, resulting in a serious hazard.
5.
Confi rming condition of the environment:
Confi rm that the work site is placed under appropriate
conditions conforming to prescribed precautions.
6.
Fitting and adjusting the wheel guard
The wheel guard is a protective device to prevent
injury should the cutting wheel shatter during
operation. Ensure that the guard is properly fitted
and fastened before commencing cutting operation.
By slightly loosening the setting screw, the wheel
guard can be turned and set at any desired angle for
maximum operational eff ectiveness. Ensure that the
setting screw is thoroughly tightened after adjusting
the wheel guard.
7.
Cutting wheel
Ensure that the cutting wheel to be utilized is the
correct type and free of cracks or surface defects.
Also ensure that the cutting wheel is properly
mounted and the wheel nut is securely tightened.
Refer to the section on "Cutting Wheel Assembly".
ASSEMBLY AND OPERATION
8.
Conducting a trial run
Before commencing cutting operation, the machine
should be given a trial run in a safe area to ensure
that it is properly assembled and that the cutting
wheel is free from obvious defects.
Recommended trial runs durations are as follows:
After replacing
cutting wheel ......... 3 minutes or more
Prior to starting
routine work ........... 1 minute or more
9.
Confi rming the lock pin.
Confi rm that the lock pin is disengaged by pushing
lock pin two or three times before switching the
power tool on (See Fig. 2).
PRACTICAL CUT-OFF MACHINE
APPLICATION
1.
Cutting force
To prolong the life of the machine and ensure a fi rst
class fi nish. It is important that the machine should
not be overloaded by applying too much force.
2.
Precautions immediately after fi nishing operation
After switching off the machine, do not put it down
until the cutting wheel has come to a complete
stop. Apart from avoiding serious accidents, this
precaution will reduce the amount of dust and swarf
sucked into the machine.
CAUTION
After operation, always place the machine so
that the cutting wheel faces upward.
When the machine is not in use, the power
source should be disconnected.
CUTTING WHEEL ASSEMBLY
1.
Assembling (Fig. 2, 3)
(1) Turn the machine upside down so that the spindle is
facing upward.
(2) Mount the wheel washer onto the spindle.
(3) Fit the protuberance of the cutting wheel onto the
wheel washer.
(4) Put the inner washer on the cutting wheel, and screw
the wheel nut onto the spindle.
(5) Insert the lock pin to prevent rotation of the spindle,
and tighten the wheel nut with accessory wrench, as
shown in Fig. 3.
