WORKPLACE SAFETY
• Keep the workplace clean and bright to avoid
accidents due to messy and dark sites.
• Do not operate power tools in explosive envi-
ronment, such as those with ammable liquid,
gas or dust. Sparks generated in operation may
ignite dust or gas.
• When operating power tools, keep away from
children and bystanders. Please focus on the
operation to avoid losing control of the tools.
ELECTRIC SAFETY
• Please use well-matched plug and socket.
Modied plugs not allowed. Power tools to be
grounded shall not use any conversion plug. To
reduce the risk of electric shock, please keep
the unmodied plugs with matching sockets.
• To avoid shock risks, operators shall not con-
tact with the grounding surfaces, such as pipes,
radiators or refrigerators.
• Do not expose power tools to rain or wet envi-
ronment, which may increase the shock risks.
• Do not abuse wires such as to carry, pull or
unplug the power tools. Please keep the wires
away from heat, oil, sharp edges or moving
parts to avoid shock risks due to damaged or
twisted wires.
• When using power tools outdoors, please use
extension cords suitable for outdoor use to
reduce shock risks.
PERSONAL SAFETY
• Stay alert and avoid operating power tools when
tired, under the inuence of drugs or alcohol,
or during medical treatment, as this can lead to
serious injury.
• Always wear goggles and, when necessary,
use additional protective equipment like dust
masks, non-slip safety shoes, safety helmets,
and hearing protection to reduce the risk of
personal injury.
• Before connecting the power supply or battery
pack, picking up, or carrying the tool, ensure
the switch is in the off position to prevent
accidental starting. Energizing the tool with
ngers on the switch or when the switch is on
can be extremely dangerous.
