q) Regularly clean the power tool's air vents. The motor's fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical hazards.
r) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
s) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution
or shock.
2) KICKBACK AND RELATED WARNINGS
• Kickback is a sudden reaction to a pinched or snagged rotating wheel, sanding band, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the accessory's rotation at the point of the binding. • 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. The wheel may either jump toward or away from the
operator, depending on the direction of the wheel's movement at the point of pinching. 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.
a) 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 kickback forces, if proper precautions are taken.
b) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners,
sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
c) Do not attach a thin toothed saw blade. Such blades create frequent kickback and loss of control.
d) Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is
the same direction as the chips are thrown). Feeding the tool in the wrong direction causes the cutting edge of the bit to
climb out of the work and pull the tool in the direction of this feed.
e) When using steel saws, cut-off wheels, high-speed cutters or tungsten carbide cutters, always have the work
securely clamped. These wheels will grab if they become slightly canted in the groove, and can kickback. When a cut-off
wheel grabs, the wheel itself usually breaks. When the steel saw, high-speed cutters or tungsten carbide cutter grab, it
may jump from the groove and you could lose control of the tool.
3) SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING-OFF OPERATIONS
a) Use only wheel types that are recommended for your power tool and 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.
b) For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange
that are of correct size and length. Proper mandrels will reduce the possibility of breakage.
c) Do not "jam" the cut-off 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.
d) Do not position your hand in line with and behind the rotating wheel. When the wheel, at the point of operation, is
moving away from your hand, the possible kickback may propel the spinning wheel and the power tool directly at you.
e) When the 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 cut-off 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.
f) 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.
g) 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.
h) 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.
4) SAFETY WARNINGS SPECIFIC FOR WIRE BRUSHING OPERATIONS
a) Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/ or skin.
b) Allow brushes to run at operating speed for at least one minute before using them. During this time no one is to
stand in front or in line with the brush. Loose bristles or wires will be discharged during the run-in time.
c) Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be
discharged at high velocity during the use of these brushes and may become imbedded in your skin.
GENERAL
• This tool should not be used by people under the age of 16 years • Only use this tool for applications without the
use of water 10 • Always disconnect plug from power source before making any adjustment or changing any accessory
ACCESSORIES • RAIDER can assure flawless functioning of the tool only when original accessories are used • Use only
accessories recommended by RAIDER • For mounting/using non-RAIDER accessories observe the instructions of the
manufacturer concerned • Use only accessories with an allowable speed matching at least the highest no-load speed of
the tool • Do not use damaged, deformed or vibrating accessories • Handle and store grinding/cutting discs carefully to
avoid chipping and cracking • Protect accessories from impact, shock and grease • Never use grinding discs over 32 mm
(1 1/4") Ø • Never use drill bits over 3.2 mm (1/8") Ø • Never use a cutting disc for side grinding • Never use reducors or
adaptors to fit large-hole grinding/ cutting discs
BEFORE USE
• Always check that the supply voltage is the same as the voltage indicated on the nameplate of the tool (tools with a
rating of 230V or 240V can also be connected to a 220V supply) • Do not work materials containing asbestos (asbestos
is considered carcinogenic) • Secure the workpiece (a workpiece clamped with clamping devices or in a vice is held more
securely than by hand) • Use completely unrolled and safe extension cords with a capacity of 16 Amps (U.K. 13 Amps) •
Wear protective glasses and hearing protection , protective gloves and sturdy shoes; when necessary, also wear an apron
• Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful (contact with
or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders); wear a
dust mask and work with a dust extraction device when connectable • Certain kinds of dust are classified as carcinogenic
(such as oak and beech dust) especially in conjunction with additives for wood conditioning; wear a dust mask and work
with a dust extraction device when connectable • Follow the dust-related national requirements for the materials you want
to work with.
