English
b) The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
Animproperlymountedwheelthatprojectsthroughthe
planeoftheguardlipcannotbeadequatelyprotected.
c)
The guard must be securely attached to the power
tool and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken
wheel fragments, accidental contact with wheel and
sparksthatcouldigniteclothing.
d) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-o wheel.
Abrasive cut-o wheels are intended for peripheral
grinding,sideforcesappliedtothesewheelsmaycause
themtoshatter.
e) Always use undamaged wheel anges that are of
correct size and shape for your selected wheel.
Properwheel angessupportthe wheelthusreducing
the possibility of wheel breakage. Flanges for cut-o
wheelsmaybedierentfromgrindingwheelanges.
f) Do not use worn down wheels from larger power
tools.
Wheelintendedforlargerpowertoolisnotsuitablefor
thehigherspeedofasmallertoolandmayburst.
ADDITIONAL SAFETY WARNINGS
SPECIFIC FOR ABRASIVE CUTTING-
OFF OPERATIONS
a) Do not “jam” the cut-o 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bindingofthewheelinthecut
andthepossibilityofkickbackorwheelbreakage.
b) Do not position your body in line with and behind
the rotating wheel.
When the wheel, at the point of operation, is moving
awayfromyourbody,thepossiblekickbackmaypropel
thespinningwheelandthepowertooldirectlyatyou.
c) When wheel is binding or when interrupting a cut
for any reason, switch o the power tool and hold
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the cut-
o 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.
d) 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.
e) 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.
f) 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.
GENERAL SAFETY INSTRUCTIONS
FOR GRINDERS
– Check that speed marked on the wheel is equal to or
greater than the rated speed of the grinder;
– Ensure that the wheel dimensions are compatible with
the grinder;
– Abrasive wheels shall be stored and handled with care in
accordance with manufacturer’s instructions;
– Inspect the grinding wheel before use, do not use
chipped, cracked or otherwise defective products;
– Ensure that mounted wheels and points are tted in
accordance with the manufacturer’s instructions;
–
Ensure that blotters are used when they are provided with
the bonded abrasive product and when they are required;
– Ensure that the abrasive product is correctly mounted
and tightened before use and run the tool at no-load for
30 seconds in a safe position, stop immediately if there
is considerable vibration or if other defects are detected.
If this condition occurs, check the machine to determine
the cause;
– If a guard is equipped with the tool never use the tool
without such a guard;
– When using a abrasive cutting wheel, be sure to remove
the standard accessory wheel guard and attach the
wheel guard with side guard (sold separately) (Fig. 4);
– Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
– For tools intended to be tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;
– Check that the work piece is properly supported;
– Do not use cutting o wheel for side grinding;
–
Ensure that sparks resulting from use do not create a hazard
e.g. do not hit persons, or ignite ammable substances;
– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, rst disconnect the tool from
the mains supply (use non metallic objects) and avoid
damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves, helmet
and apron should be worn;
– Pay attention to the wheel that continues to rotate after
the tool is switched o.
ADDITIONAL SAFETY WARNINGS
1.
Ensure that the power source to be utilized conforms to the
power requirements specied on the product nameplate.
2. Ensure that the power switch is in the OFF position. If the
plug is connected to a receptacle while the power switch
is in the ON position, the power tool will start operating
immediately, which could cause a serious accident.
3.
When the work area is removed from the power source, use
an extension cord of sucient thickness and rated capacity.
The extension cord should be kept as short as practicable.
4. Ensure that mounted wheels and points are tted in
accordance with the manufacturer’s instructions.
Ensure that the depressed center wheel to be utilized is
the correct type and free of cracks or surface defects.
Also ensure that the depressed center wheel is properly
mounted and the wheel nut is securely tightened.
Ensure that blotters are used when they are provided with
the bonded abrasive product and when they are required.
Do not use separate reducing bushings or adaptors to
adapt large hole abrasive wheels.
For tools intended to be tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length.
5. Do not use cutting o wheel for side grinding.
6. Ensure that the abrasive products is correctly mounted
and tightened before use and run the tool at no-load for
30 seconds in a safe position, stop immediately if there
is considerable vibration or if other defects are detected.
If this condition occurs, check the machine to determine
the cause.
