PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms

to the power requirements specified on the product

nameplate.

2. Power switch

Ensure that the power switch is in the OFF position.

If the plug is connected to a power 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 sufficient thickness

and rated capacity. The extension cord should be

kept as short as practicable.

4. Checking and installing the diamond wheel

Check the diamond wheel is a specified one and

is not cracked, broken or bent. Check the diamond

wheel is installed securely. For installation, refer to

“Installing/removing diamond wheel”.

5. Dust collection cover (Fig. 1, Fig. 2)

The dust collection cover is a protective device to

prevent injury should the diamond wheel shatter

during operation. Ensure that the cover is properly

fitted and fastened before commencing cutting

operation.

6. Spindle lock mechanism

Confirm that the spindle lock is disengaged by

pushing push button two or three times before

switching the power tool on (See Fig. 3).

7. Cutting depth adjustment (Fig. 6)

After loosening the knob bolt (Fig. 1) the wall chaser

can be sent to any desired depth between 0 mm

and 35 mm according to the scale on the dust guard

(Fig 6). Ensure that the knob bolt is fully tightened

once cutting depth has been adjusted and set.

CORRECT SPECIFICATION OF THE PLUG

Applied only for 110V Wall Chasers supplied without

plug.

Ensure that the plug to be installed has a current capacity

superior than the Wall Chaser current according to the

following table.

* Be sure to check the nameplate on product as it is

subject to change by areas.

NOTE:

Never install a plug with a current capacity lower

than the specified data on the above table.

INSTALLING DUST COLLECTION HOSE

When cutting a material which generates cutting dust,

use the dust collection hose as follows:

⅜ Install the dust collector hose for the power tool.

(Fig. 7)

INSTALLING/REMOVING DIAMOND WHEEL

1. Removal (Fig. 1-5)

(1) Disconnect the machine from the power supply.

(2) Place the machine on a level surface with the dust

cover facing upwards.

(3) Remove the knob bolt at the front of the dust cover

which secures the dust guard.

(4) Pivot the dust guard out and away from the dust

cover.

(5) Lock the drive shaft in place by pressing in the push

button (spindle lock).

(6) While holding the push button in place, remove the

diamond wheel retention M14 bolt using the 22 mm

wrench supplied.

(7) Remove the blade spacers and diamond wheels

from the drive shaft.

2. Installation (Fig. 1-6)

(1) Disconnect the machine from the power supply.

(2) Fit the blade spacer (3) onto the drive shaft.

(3) Place the first diamond wheel onto the drive shaft.

(4) Put the next blade spacer (5)/spacers onto the drive

shaft in order to create the desired cutting width.

(5) Place the second diamond wheel onto the drive

shaft.

(6) Fit the remaining spacer if not already applied.

(7) Fit the blade washer, ensuring that the concave side

is facing toward the drive shaft.

(8) Secure the diamond wheel retention M14 bolt while

holding the push button as before.

(9) Ensure that the diamond wheels are secure and that

there is no lateral movement or rotation of the

diamond wheels on the drive shaft.

(

) Secure the dust guard and lock in place at the

required cutting depth by tightening the knob bolt.

CUTTING

1. Cutting procedures (Fig. 8)

(1) Place part A on the material to be cut, making sure

that the diamond wheel is not touching the material.

(2) Switch on and slowly cut a slit in the direction of

the arrow B.

(3) Cut along the cutting line in the direction of the

arrow C.

2. Switch operation

Switch ON: Push the locking button forward and

then press the switch lever.

* For continuous use, press the switch

lever. The switch lever is locked by

pushing the locking button forward

once again.

(*Subject to change depending on

area.)

Switch OFF: Press and release the switch lever.

3. Precautions immediately after finishing operation

After switching off the machine, do not put it down

until the depressed center wheel has come to a

complete stop. Apart from avoiding serious accidents,

this precaution will reduce the amount of dust and

swarf sucked into the machine.

CAUTION

⅜ Always check the diamond wheel before starting

work. Never use a diamond wheel which is cracked,

broken or bent.
