Always position the unit on the operator's right side. The
use of the unit on the operator's left side will expose the
user to hot surfaces and can result in possible burn injury.
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the power head with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Power head should be held at
a comfortable position with the rear handle about hip height.

tachment installed.
Always operate power head at full throttle. If debris becomes
wrapped around the attachment, STOP THE ENGINE, dis-
connect the spark plug wire, and remove the debris. Pro-
longed use at partial throttle will result in lubricant dripping
from the muffler.
