Kickback will propel the tool in direction opposite to

the wheel’s movement at the point of snagging.

d) Use special care when working corners, sharp edges

etc. Avoid bouncing and snagging the wheel.

Corners, sharp edges or bouncing have a tendency

to snag the rotating wheel and cause loss of control

or kickback.

e) Do not attach a saw chain woodcarving blade or

toothed saw blade.

Such blades create frequent kickback and loss of

control.

f) Do not “jam” the wheel or apply excessive pressure.

Do not attempt to make an excessive depth of cut.

Overstressing the wheel increases the loading and

susceptibility to twisting or blinding of the wheel in

the cut and the possibility of kickback or wheel

breakage.

g) When wheel is binding or when interrupting a cut

for any reason, switch off the power tool and hold

the power tool motionless until the wheel comes to

a complete stop. Never attempt to remove the wheel

from the cut while the wheel is in motion otherwise

kickback may occur.

Investigate and take corrective action to eliminate

the cause of wheel binding.

h) Do not restart the cutting operation in the workpiece.

Let the wheel reach full speed and carefully re-enter

the cut.

The wheel may bind, walk up or kickback if the power

tool is restarted in the workpiece.

i) Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kickback.

Large workpieces tend to sag under their own weight.

Supports must be placed under the workpiece near

the line of cut and near the edge of the workpiece on

both sides of the wheel.

j) Use extra caution when making a “pocket cut” into

existing walls or other blind areas.

The protruding wheel may cut gas or water pipes,

electrical wiring or objects that can cause kickback.

PRECAUTION ON USING WALL CHASER

1. Never operate these power tools without wheel

guards attached.

2. Do not over-reach when operating the wall chaser.

3. Check that the speed marked on the diamond wheels

or cutting wheel is equal to or greater than the rated

speed of the wall chaser.

4. Use only specified diamond wheels and cutting

wheels.

5. Diamond wheels and cutting wheels shall be stored

and handled with care in accordance with

manufacturer’s instructions.

6. Inspect the diamond wheel or cutting wheel before

use, do not use chipped, cracked or otherwise

defective products.

7. Always hold the body handle and top handle of the

power tool firmly. Otherwise the counter force

produced may result in inaccurate and even

dangerous operation.

8. Do not use separate reducing bushings or adapters

to adapt cutting wheels with a bore other than 22.2

mm.

9. Do not use this machine to cut asbestos.

10. The diamond wheels continue to rotate after the

tool is switched off.

11. Wear a dust mask.

Do not inhale the harmful dusts generated in cutting

operation. The dust can endanger the health of

yourself and bystanders.

STANDARD ACCESSORIES

(1) 22 mm Wrench ......................................................... 1

(2) Side handle ................................................................ 1

Standard accessories are subject to change without notice.

APPLICATION

Cutting slits in concrete, cement, brick or tiles. Slits can
