7.
If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
Power tool use and care
1.
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
2.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
3.
Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and
4.
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
5.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool's operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.

Cutter safety warnings
Cut-off machine safety warnings
The guard provided with the tool must be
1.
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the oper-
ator. Position yourself and bystanders away
from the plane of the rotating wheel. The guard
helps to protect operator from broken wheel frag-
ments and accidental contact with wheel.
2.
Use only diamond cut-off wheels for your
power tool. Just because an accessory can be
attached to your power tool, it does not assure
safe operation.
3.
The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fly apart.
Wheels must be used only for recommended
4.
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to

6.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7.
Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
Service
1.
Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2.
Follow instruction for lubricating and chang-
ing accessories.
3.
Keep handles dry, clean and free from oil and
grease.
USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size
to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.

shatter.
5.
Always use undamaged wheel flanges that are
of correct diameter for your selected wheel.
Proper wheel flanges support the wheel thus
reducing the possibility of wheel breakage.
6.
The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
7.
The arbour hole size of wheels and flanges must
properly fit the spindle of the power tool. Wheels and
flanges with arbour holes that do not match the mount-
ing hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
Do not use damaged wheels. Before each
8.
use, inspect the wheels for chips and cracks.
If power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool
at maximum no load speed for one minute.
Damaged wheels will normally break apart during
this test time.
