Cut-Off Machine Safety Warnings; Kickback And Related Warnings - Ryobi ECO2335HG Manual

■
Maintain power tools and accessories. 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.
■
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
■
Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking 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.
■
Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
SERVICE
■
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.

CUT-OFF MACHINE SAFETY WARNINGS

■
Position yourself and bystander away from the
plane of the rotating wheel. The guard helps to
protect the operator from broken wheel fragments and
accidental contact with wheel.
■
Use only bonded reinforced cut-off wheels for
your power tool. Just because an accessory can be
attached to your power tool, it does not assure safe
operation.
■
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
applications. For example: do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
■
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.
■
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.
■
The arbour 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
mounting 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 use,
inspect the wheels for chips and cracks. If the
power tool or wheel is dropped, inspect for damage
or install an undamaged wheel. After inspecting
and installing the wheel, position yourself and

Original Instructions
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.
■
Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask
or respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
■
Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective
workpiece or of a broken wheel may fly away and cause
injury beyond immediate area of operation.
■
Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged and
your hand or arm may be pulled into the spinning wheel.
■
Regularly clean the power tool's air vents. The
motor's fan can draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
■
Do not operate the power tool near flammable
materials. Do not operate the power tool while
placed on a combustible surface such as wood.
Sparks could ignite these materials.
■
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.

KICKBACK AND RELATED WARNINGS

Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stalling
of the rotating wheel which in turn causes the uncontrolled
cutting unit to be forced upwards toward the operator.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the material
causing the wheel to climb out or kick out. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
■
Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. The operator can control upward kickback
forces, if proper precautions are taken.
■
Do not position your body in line with the rotating
wheel. If kickback occurs, it will propel the cutting unit
upwards toward the operator.
■
Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
■
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 binding of the wheel in the
cut and the possibility of kickback or wheel breakage.
■
When the wheel is binding or when interrupting a
equipment. Fragments of
