OPERATING THE TRIMMER
See Figure 9.
WARNING:
Engine housing can become hot during trimmer operation.
Do not rest or place your arm, hand, or any body part
against the engine housing during trimmer operation.
Only hold the trimmer as shown in figure 9 with all body
parts clear of engine housing. Extended contact with
the engine housing can result in burns or other injuries.
WARNING:
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.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer 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. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which
could cause damage from overheating. If grass becomes
wrapped around the string head, STOP THE ENGINE,
disconnect the spark plug wire, and remove the grass.
WARNING:
Always hold the string trimmer away from the body
keeping clearance between the body and the product.
Any contact with the housing or string trimmer cutting
head can result in burns and/or other serious personal
injury.
