engine is on. Do not touch the engine or the muffler
for a while after the engine stops. Hot surfaces can
cause injuries.

damaged. The parts can contain some carcinogenic
chemicals.

• Make sure that you wind the grass trimmer line
tightly and equally around the drum to decrease the

maintenance on the blade.
• Use head protection when you operate a product
with a grass blade.
• Grass blades and grass cutters are used to cut
rough grass.
• A grass blade can cause injury while it continues
to spin after the engine is stopped or the throttle
trigger is released. Make sure that the grass
blade has completely stopped rotating before any
maintenance.
• Stop the engine before you do work on the cutting
attachment. Make sure the cutting attachment fully
stops. Disconnect the lead from the spark plug.
• Only use an approved cutting attachment or a
correctly sharpened blade.
