PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements speciﬁ ed on the product nameplate.

2. Power switch

Ensure that the power switch is in the OFF position. If the

plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. Extension cord

When the work area is removed from the power source,

use an extension cord of suﬃ cient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Install the machine on a level ﬂ at place, and keep it in

a stable condition. Prior to shipping, the equipment is subjected to a rigid factory inspection to prevent electric shocks during operation.

5. Since movable portions are secured by tension of a chain

while in transit, remove the chain from the chain hook by slightly depressing the switch handle.

6. Ascertain that all cut-oﬀ wheels are in perfect condition,

and do not display scars and cracks.

7. Although they have been fully clamped at the factory

prior to delivery, reclamp the clamping nuts securely for safety.

8. Possible accidents such as a cracked cut-oﬀ wheel

is prevented by this protective cover (wheel cover). Although it has been fully clamped at the factory prior to delivery, securely reclamp the mounting screws for safety.

9. When replacing the cut-oﬀ wheel, ensure that the

replacement cutting wheel has a designed circumferential speed in excess of 4800 m/min.

10. Ensure that the bar spanner used for tightening or

removing the cut-oﬀ wheel is not attached to the machine.

11. Check that the work piece is properly supported. Ensure

that the material is securely fastened with the vise. If it is not, a serious accident could be caused if the material comes loose or the cut-oﬀ wheel breaks during operation.

12. Ensure that the abrasive wheel is correctly ﬁ tted and

tightened before use and run the machine at no-load for 30 second in safe position, stop immediately if there is a considerable vibration or if other defects are detected. If this condition occurs, check the machine to determine the cause.

13. Rotate the cut-oﬀ wheel to inspect any facial deﬂ ection.

A heavy deﬂ ection will cause the cut-oﬀ wheel to shift.

14. Ensure that ventilation openings are kept clear when

working in dusty conditions. If it should become necessary to clear dust, ﬁ rst disconnect the machine from the mains supply.

CUTTING PROCEDURES

CAUTION

It is dangerous to remove or install the workpiece while

the cut-oﬀ wheel turning.

1. Operating the switch

Switch operations diﬀ er in accordance with the region.

Power will be turned on when the switch is pulled, and turned oﬀ when released. (Fig.2)

<Lock-on Switch Operations>

For models equipped with a switch lock, press the switch

lock when the switch is being pulled to enable operations to be continued ever after the switch is released. (Fig.2)

2. Cutting

(1) Rotate the cut-oﬀ wheel, gently press down the handle,

and bring the cut-oﬀ wheel close to the cutting material.

(2) When the cut-oﬀ wheel contacts the cutting material,

gently press down the handle further and start cutting.

(3) When cutting (or designated slotting) is completed, raise

the handle and restore it to its original position.

English

(4) At the termination of each cutting process, turn OFF the

switch to stop rotation and proceed with the subsequent cutting job.

CAUTION

It does not necessarily cut rapidly when putting more

force on the handle.

Too much force on the handle will put excessive pressure

on the motor and reduce its capacity.

Do not fail to switch OFF the switch after operation is

completed and pull the plug out.

MOUNTING AND DISMOUNTING THE CUT-OFF WHEEL

1. Dismounting the cut-oﬀ wheel (Fig. 3 and 4)

(1) Raise lower gurd (A) . Press down on the stopper pin to bring it into contact with

the wheel washer.

Rotate the cut-oﬀ wheel, pass the stopper pin through the

hole on the wheel washer, and then remove the M10 bolt with the hexagonal bar wrench supplied.

(2) Remove the bolt, washer (A), and the wheel washer and

detach the cut-oﬀ wheel. (Fig. 4)

CAUTION

Do not remove the O-ring or sleeve from the cut-oﬀ wheel

spindle.

2. Mounting the cut-oﬀ wheel

Throughly remove dust from the wheel washers and

bolt then mount the wheel by following the dismounting procedures in reverse order. Return lower gurd (A) to its original position.

CAUTION

Conﬁ rm that the stopper which was used for installation

and removal of the cut-oﬀ wheel has returned to the retract position.

HOW TO OPERATE

1. Procedure for ﬁ xing the cutting material (Fig. 5 and 6)

Place the workpiece material between vise (A) and vise

(B), raise the clutch and push the screw handle to bring vise (A) lightly into contact with the workpiece material, as shown in Fig. 5.

Then, turn the clutch down, and securely ﬁ x the

workpiece material in position by turning the screw handle. When the cutting job is completed, turn the screw handle 2 or 3 times to loosen the vise (A), and remove the workpiece material, as shown in

Fig. 6.

CAUTION

Never remove or install a workpiece material while the

cut-oﬀ wheel is rotating, to avoid personal injury.

2. Cutting at angles (Fig. 7)

(1) The machine permits cutting at angles of 0° – 45°. (2) Loosen the two M10 hexagon socket head bolts on the

vice (B), then set the working surface on the vice-jaw at any angles of 0°, 30°, or 45° . Upon completion of setting, securely tighten the two 10 mm bolts.

3. Moving the stationary vise-jaw (Fig. 8)

The vise opening is set at the maximum of

165 mm when shipped from the factory. In case an opening of more than 165 mm is required, move the vise to the position shown by the chain line after unscrewing the two bolts. The maximum opening can be set in two steps 200 mm and 235 mm. When the cutting material is excessively wide, the vise can be eﬀ ectively used by repositioning the stationary side of the vise-jaws.

4. Cutting Long Workpiece Materials (Fig.9)

Make sure you place both ends of long workpiece

materials on blocks that are the same height as the base to stabilize it prior to beginning work.

5. How to use square block (Fig. 10)

When the cut-oﬀ wheel has a reduced outer diameter,

insert between the vise (A) and (B) a square block slightly smaller than the dimension of workpiece being cut to use the cut-oﬀ wheel economically.

6. Adjusting the Cutting Depth (Fig. 11)

When the cut-oﬀ wheel has a reduced outer diameter,

change the height of the stopper bolt to adjust the cutting depth. Adjustments are made by loosening the lock nut and rotating the stopper bolt. When ﬁ nished, retighten the lock nut to ﬁ x the stopper bolt in place.

It is possible to eradicate splinters depending on the

material.

CAUTION

○ Make sure the height of the stopper bolt is readjusted

when the cut-oﬀ wheel is replaced.

○ If the stopper bolt is too low, there is a chance that the

cut-oﬀ wheel will cut into the base.

7. Adjusting the Spark Sheet (Fig.12)

Loosen the screw holding the spark sheet in place with a

Phillips screwdriver to adjust the angle.

Change the angle in accordance with the prevalent

environment and the work required to adjust the direction in which the sparks ﬂ y.

8. Transporting the Unit (Fig.13)

When moving the unit, attach the chain hook onto the

chain and grip the carrying handle to carry it.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to switch oﬀ and pull oﬀ the plug from the power

outlet before inspection and maintenance.

1. Replacing a cut-oﬀ wheel

When the cut-oﬀ wheel has already become dull while

continually using, the unnecessary load is got from the motor. Consequently, redress or replace a dull cut-oﬀ wheel to ensure grinding eﬃ ciency.

2. Inspecting the carbon brushes (Fig. 14)

The Motor employs carbon brushes which are

consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones shown in the ﬁ gure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

3. 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.

4. Replacing supply cord

If the replacement of the supply cord is necessary, this

has to be done by Hitachi Authorized Service Center in order to avoid a safety hazard.

5. Lubrication

Supply oil in the following oil supply points once a month

so as to keep the machine workable for a long time.
