length. The use of correct shaft will reduce the risk of cracking.
Do not "jam" the cutting wheels or apply too much pressure to them. Do not try to increase the cutting depth. Excessive pressure
on wheel increases the load, torsion and abrasion resistance during cutting, and the likelihood of a rebound or damage to wheel.
Do not place your hands in the line and behind the spinning wheel. If in the course of work the disc moves away from your
hands, then in the case of rebound the rotating wheel and tool will be directed towards the operator.
If the wheel has been seized, locked, or in the event of discontinued cutting for any reason, turn off the tool and hold it
idle until the wheel stops completely. Never attempt to release a cutting wheel from a saw cut if the wheel is in motion,
otherwise it may cause a rebound. Investigate the causes and take the correct steps to eliminate the cause of locking the wheel.
Do not resume cutting in the workpiece. Let the wheel reach full rotational speed, and then carefully resume cutting. The
wheel may be locked, get out of the material or bounce if the power tool is started while in the workpiece.
In order to avoid wheel clamping or bouncing, you have to support panels and other oversized materials. Large-size
materials tend to bend under their own weight. Supports must be placed under the workpiece near the line of cutting and near the
edge of the material on both sides of the cutting line.
Special caution must be taken when cutting cavities in walls or other surfaces. The wheel can cut gas and water pipes or
electric cables, as well as objects that will cause a rebound.
Warnings related to work with wire brush
Caution must be taken, because the wire splinters are ejected out of the brush also during normal operation. Do not
overload the wires by applying excessive force to the brush. Wires can easily puncture light clothing and/or skin.
Before the use, for at least one minute let brushes reach the operating speed. Then, no one can stand in front of or in line
of the brush. Loose splinters of wires or wires will be thrown out of the brush during this operation.
Direct the material from the spinning brush away from you. While working, small splinters and small pieces of wire can be
thrown out at high speed and stick into the skin.
INSTALLATION OF ACCESSORIES
CAUTION! All operations mentioned in this chapter must be carried out with the power supply disconnected – the battery must
be disconnected from the tool!
Installation of tooling in the tool chuck (II)
It may be necessary to loosen the fi xing nut before inserting a tool into the chuck. To do this, hold the spindle with one spanner
and unscrew the nut with the other. The nut should not be completely taken off the chuck.
Place the shank of the tool in the chuck. There must be a gap of no more than 8 mm between the working part of the tool and the
chuck. Moreover, make sure that at least half of the tool shank is inside the chuck.
Remove the tooling by by loosening the fi xing nut.
Warning! The tooling might be hot immediately after fi nishing work. Allow it to cool down itself before removing.
TOOL OPERATION
Rechargeable battery
Only one of the following YATO Li-Ion 18 V batteries can be used to power the tool: YT-82842, YT-82843, YT-82844, YT-82845,
which can only be charged with YATO YT-82848 or YT-82849 chargers. It is forbidden to use other batteries with a diff erent rated
voltage and not matching the device battery socket. It is forbidden to modify the socket or battery to make them match.
Slide the battery into the socket with the contacts facing inside the tool until the battery latch engages. Make sure that the battery
will not slide out on its own during operation. Disconnect the battery by pressing and holding the latch and then pulling the battery
out of the tool housing.
Starting and stopping the grinder
Before starting the grinder, hold it with both hands on the handles or isolated housing elements and make sure that the tool does
not come into contact with any objects. The direction of rotation of the spindle is indicated by an arrow on the tool housing near
the tool chuck.
Start the tool by pressing and holding the back of the on/off button and then sliding it forward (III). The on/off switch can be locked
in the front position which can be helpful during prolonged work.
When the tool is started up, hold it in this position for about 30 seconds, watching for any suspicious noises, excessive noise or
excessive vibration.
If no signs of malfunction are found, the tool should be switched off by releasing pressure on the switch or, if it was locked, by
pressing the back of the switch button. The button retracts automatically, but the tool can still move for some time after the switch
is released.
The tool can be put away only after the inserted tool has come to a complete standstill.
