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 sufficient
thickness and rated capacity. The extension cord
should be kept as short as practicable.
WARNING:
Damaged cord must be 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. Checking and installing the diamond wheel
Check the diamond wheel is a specified one and is
not cracked, broken or bent. Check the diamond
wheel is installed securely. For installation, refer
to "Installing/removing diamond wheel".
6. Fitting and adjusting the dust collection cover
(Fig. 2)
The dust collection cover is a protective device to
prevent injury should the diamond wheel shatter
during operation. Ensure that the cover is properly
fitted and fastened before commencing cutting
operation.
By slightly loosening the setting screw, the dust
collection cover can be turned and set at any
desired angle for maximum operational
effectiveness. Ensure that the setting screw is
thoroughly tightened after adjusting the dust
collection cover.
