English
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.
