ADDITIONAL SAFETY RULES
Wear a hard hat (safety helmet) and an ear protector if necessary.
Be sure the bit is secured
in place before operation.
Under normal operation, the tool is designed to produce vibration. The
screws can come loose easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
In coldweather or when the tool has not been usedfor a longtime, letthe
tool warm up for several minutes by operating
it under no load. This will
loosen up the lubrication. Without proper warm-up hammering operation
is difficult.
Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
Hold the tool firmly with both hands. Always use the side grip.
Keep hands away from moving parts.
Do not leave the tool running. Operate the tool only when hand-held.
Do not point the tool at any one in the area when operating. The bitcould
fly out and injure someone seriously.
When chipping into walls, floors or wherever "live" electricalwires may
be encountered,
DO NOT TOUCH ANY METAL PARTS OF THE TOOL!
Holdthe tool only by the plastic handle or the side grip to prevent electric
shock
if you chip into a "live" wire.
Do not touch the bit or parts close tothe bit immediately after operation;
they may be extremely hot and could burn your skin.
