Safety Recommendations
•
Enlist the assistance of a second person when lifting the router; do not attempt to lift the
router by yourself.

Secure your footing when lifting the router; balance the lifted weight between your feet.

Lift the assembly slowly; avoid making sudden movements; avoid twisting your body
as you lift.

bend at your knees, rather than your waist, to reduce the strain on your lower back.

— Use caution; do not become a victim yourself. Disconnect power from the system.
— If possible, send another person to get medical aid; otherwise, assess the condition

beforehand.
