*1 Before beginning work, check to ensure that operating

the switch correctly turns the tool ON and OFF.

While the tool is plugged in to the receptacle, ensure that

the sawblade stops when the switch is turned OFF.

In some regions, it is not necessary to perform step

*2 Usable sawblade diameter:

C6U3, C6BU3, C6UM, C6BUM ....... 165 to 162 mm

C7U3, C7BU3, C7UM, C7BUM ....... 190 to 185 mm

Body thickness: up to 1.5 mm, tip width: at least 1.9 mm

Riving knife thickness: 1.8 mm

*3 Use the guide rail when cutting in long, straight lines.

The rubber lip of the guide rail works to prevent

splintering on the cut surface. When using the guide rail

for the ﬁ rst time, cut the rubber lip as follows: Set the

tool’s cutting depth to the maximum and the saw blade

angle to perpendicular (0°), pull the switch completely,

and cut at a slow, constant speed.

After the rubber lip is cut, it can also be used for 45°

angle cutting.

*4 Use with C6U3, C6BU3, C7U3 and C7BU3 when using

the guide rail.

NOTE

When performing cutting operation using the guide

rail, remember that the cutting depth decreases as the

thickness of the guide rail increases.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade

Since use of as dull saw blade will degrade eﬃ ciency

and cause possible motor malfunction, sharpen or

replace the saw blade as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Inspecting the carbon brushes (Fig. 24)

The motor employs carbon brushes which are consumable

parts. Since an excessively worn carbon brush can result

in motor trouble, replace the carbon brushes with new

ones having the same carbon brush No. ⓐ shown in the

ﬁ gure when it becomes worn to or near the “wear limit” ⓑ.

In addition, always keep carbon brushes clean and ensue

that they slide freely within the brush holders.

CAUTION

○ When replacing the new carbon brushes, always

use genuine Hitachi carbon brushes with the number

speciﬁ ed in the drawing.

○ For models C6BU3, C6BUM, C7BU3 and C7BUM, the

brake may not work if other than the speciﬁ ed carbon

brushes are used.

When the brake becomes ineﬀ ective, replace the carbon

brushes with new ones.

4. Replacing carbon brushes

Disassemble the brush caps with a slotted-head

screwdriver. The carbon brushes can then be easily

removed.

5. Replacing supply cord

If the replacement of the supply cord is necessary, this

has to be done by the manufacturer of this agent in order

to avoid a safety hazard.

6. Motor unit maintenance

The motor winding is an important part of this tool. Avoid

damaging and be careful to avoid contact with cleaning

oil or water.

After 50 hours of use, clean the motor by blowing into the

ventilation holes of the motor housing with dry air from an

air gun or other tool (Fig. 25).

Dust or particle accumulation in the motor can result in

damage.

7. Inspecting and maintaining the lower guard

Always make sure that the lower guard moves smoothly.

In the event of any malfunction, immediately repair the

lower guard.

For cleaning and maintenance, use an air gun or other

tool to blow clean the space between the lower guard

and gear cover as well as the rotation part of the lower

guard with dry air (Fig. 25).

Doing so is eﬀ ective for the emission of chips or other

particles.

Accumulation of chips or other particles around the lower

guard may result in malfunction or damage.
