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.
Safety Warnings Specific for Sanding Operations
a) Do not use excessively oversized sanding disc paper. Follow manufacturer's
recommendations when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specific for Polishing Operations
a) Do not allow any loose portion of the polishing bonnet or its attachment
strings to spin freely. Tuck away or trim any loose attachment strings. Loose
and spinning attachment strings can entangle your fingers or snag on the
workpiece.
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) If the use of a guard is recommended for wire brushing, do not allow any
interference of the wire wheel or brush with the guard. Wire wheel or brush
may expand in diameter due to work load and centrifugal forces.
Additional Safety Rules for Grinders
WARNING: The grinding wheel or accessory may loosen during coast-down of
the tool when shut off. If grinding wheel or accessory loosens, it may dismount from
the machine and may cause serious personal injury.
Use of accessories not specified in this manual is not recommended and may
be hazardous. Use of power boosters that would cause the tool to be driven at
speeds greater than its rated speed constitutes misuse.
Use clamps or another practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable
and may lead to loss of control.
Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the
tool and inspect the wheel for cracks or flaws.
Always handle and store wheels in a careful manner.
Never cut into area that may contain electrical wiring or piping. Serious injury
may result.
Do not operate this tool for long periods of time. Vibration caused by the
operating action of this tool may cause permanent injury to fingers, hands, and
arms. Use gloves to provide extra cushion, take frequent rest periods, and limit
daily time of use.
Direct the Dust Ejection System (DES) away from operator and coworkers.
Serious injury may result.
When not in use, place grinder on a stable surface where it will not move
inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury
may result.
Air vents often cover moving parts and should be avoided. Loose clothes,
jewelry or long hair can be caught in moving parts.
An extension cord must have adequate wire size (AWG or American Wire
Gauge) for safety. The smaller the gauge number of the wire, the greater the
capacity of the cable, that is 16 gauge has more capacity than 18 gauge. An
undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the total length,
be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
• Air vents often cover moving parts and should be avoided. Loose clothes,
jewellery or long hair can be caught in moving parts.
WARNING: We recommend the use of a residual current device with a residual
current rating of 30mA or less.
WARNING: ALWAYS wear approved protective safety equipment complying with
the following standards:
• Eye protection: AS/NZS1337 Eye Protectors for Industrial Applications;
• Hearing protection: AS/NZS1270 Acoustics – Hearing Protection;
• Respiratory protection: AS/NZS1716 Respiratory Protective Devices.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
