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 faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Check your work environment
Confirm that the work site is placed under
appropriate conditions conforming to prescribed
precautions.
6. Side handle attachment
Attach the side handle to the mounting part.
Rotate the side handle grip in a clockwise direction
to secure it.
Set the side handle to a position that is suited to
the operation and then securely tighten the side
handle grip.
7. Selecting the appropriate drill bit
When boring concrete or stone
Use the drill bits specified in the Optional
Accessories.
