ASSEMBLY AND OPERATION
APPLICATIONS
Cutting Various types of wood.
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.Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.
6.Prepare a wooden workbench (Fig. 2)
Since the saw blade will extend beyond the lower surface of the work piece, place the work piece on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation.

CAUTION:
To avoid possible accident, always ensure that the portion of work piece remaining after cutting is securely anchored or held in position.
7.Check if lever (A)s are tightened.
If the lever (A) to adjust cutting depth (Fig. 3) and lever (A) to adjust angle of inclination (Fig. 4) are loose, injury can result. Make sure that they are tightened securely.
8.Check performance of safety cover
WARNING:
Make absolutely sure that the safety cover is not fixed. Also, check and see if it can move smoothly. If the saw blade is kept exposed injury can result.
The lower guard (refer to Fig. 1) serves to protect your body from coming into contact with the saw blade. Make absolutely certain that the cover smoothly performs to cover the saw blade. If the safety cover should not move smoothly, never use it without repairing it.
In such a case, get in touch with the store where you bought the circular saw or the HITACHI Authorized Service Center for necessary repair.
9.Eye protection
When you use the tool, make certain that you wear eye protection.
10.Check if saw blade is tightened
Refer to [mounting and dismounting the saw blade] in Page 12, and make sure that the flange bolt is tightened securely.
11.Check for proper operation of the brake.
Your saw has an automatic electric brake which is designed to stop the blade from coasting in about 3 seconds, after you release the trigger switch. It is useful when making certain cuts in wood where a coasting blade would result a wide imprecise cut. Occasionally, under certain conditions, the brake will not function properly and won't stop the saw in the 3 seconds discussed above.
If this condition persists, turn the saw on and off four or five times. If the brake still does not stop the blade in about 3 seconds, the problem may be worn brushes. Replace the brushes and try the saw again. If the problem still persists, have the tool serviced at a HITACHI AUTHRIZED SERVICE CENTER.
