* Tighten the bolt (A) so it does not come loose during operation. Confirm the bolt (A) has been properly tightened before the power tool is started.

1. 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 15" (380 mm) in diameter. Always install saw blades that are 15" (380 mm) in diameter or less.

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.

1. Inspecting the carbon brushes (Fig. 26, 27)

The carbon brushes in the motor are expendable parts.

If the carbon brushes become excessively worn, motor trouble might occur.

Therefore, inspect the carbon brushes periodically and replace them when they have become worn to the wear limit line as shown in Fig. 26.

Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders.

The carbon brushes can easily be removed after removal of the brush caps (see Fig. 27) with a slotted (minus) screwdriver.

Wear Limit Line 44 1/4" (6 mm) 5/8" (16 mm) No. 44 indicates the last two numbers of carbon brush Code No.

1. Inspecting the mounting screws

Regularly inspect each component of the power tool for looseness.

Re-tighten mounting screws on any loose part.

⚠ WARNING: To prevent personal injury, never operate the power tool if any components are loose.

4. Inspecting the safety cover for proper operation

Before each use of the tool, test the safety cover (see Fig. 6) to assure that it is in good condition and that it moves smoothly.

Never use the tool unless the safety cover operates properly and it is in good mechanical condition.

5. Storage

After operation of the tool has been completed, check that the following has been performed:

(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,
(3) Lock-off button has been removed and stored in a secure place.

When the tool is not in use, keep it stored in a dry place out of the reach of children.

6. Lubrication

Lubricate the following sliding surfaces once a month to keep the power tool in good operating condition for a long time (see Fig. 1 and Fig. 2). Use of machine oil is recommended.

Oil supply points:

*Rotary portion of hinge
*Rotary portion of vise assembly
*Rotary portion of turntable and base (See Fig. 28)

7. Cleaning

Periodically remove chips, dust and other waste material from the surface of the power tool, especially from the inside of the safety cover with a damp, soapy cloth. To avoid a malfunction of the motor, protect it from contact with oil or water.

SERVICE AND REPAIRS

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used and that the double insulation system will be protected, all service (other than routine maintenance) must be performed by an AUTHORIZED HITACHI POWER TOOL REPAIR CENTER ONLY.
