!Warning!
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as always cutting with a
properly sharpened chain (which
produces wood chips rather than fine
dust) and operating the unit so that the
wind or operating process directs any
dust raised by the power tool away from
the operator. Follow the
recommendations of EPA/OSHA/
NIOSH and occupational and trade
associations with respect to dust
(“particulate matter”). When the
inhalation of dust cannot be substantially
controlled, i.e., kept at or near the
ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH/
MSHA for the type of dust encountered.
!Warning!
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be cutting
asbestos, immediately contact your
employer or a local OSHA
representative.
Operating instructions
!Warning!
Do not operate your power tool using the
starting throttle lock, as you do not have
control of the engine speed.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
!Warning!
Always stop the engine before putting a
chainsaw down.
!Warning!
The saw chain continues to move for a
short period after the throttle trigger is
released (flywheel effect).
Accelerating the engine while the saw
chain is blocked increases the load and
will cause the clutch to slip continuously.
This may occur if the throttle is
depressed for more than a few seconds
when the chain is pinched in the cut or
the chain brake is engaged. It can result
in overheating and damage to important
components (e.g. clutch, polymer
housing components) – which can then
increase the risk of injury, e.g., from the
saw chain moving while the engine is
idling.
! Warning!
Your chainsaw is equipped with a chain
catcher. It is designed to reduce the risk
of personal injury in the event of a
thrown or broken chain. From time to
time, the catcher may be damaged or
removed. To reduce the risk of personal
injury, do not operate a chainsaw with a
damaged or missing chain catcher.
