Checking Unit Condition
Use only authorized Shindaiwa parts and ac- cessories with your Shindaiwa trimmer. Do not make modifications to this unit without written approval from Shindaiwa, Inc.
WARNING!
A cutting attachment shield or other protective device is no guarantee of protection against ric-
ochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!
ALWAYS make sure the cutting attachment is properly installed and firmly tightened before operation.
NEVER use a cracked or warped cutting at- tachment: replace it with a serviceable one.
ALWAYS make sure the cutting attachment fits properly into the appropriate attachment holder. If a properly installed attachment vibrates, replace the attachment with new one and
ALWAYS stop the engine immediately and check for damage if you strike a foreign object or if the unit becomes tangled. Do not operate with broken or damaged equipment.
NEVER allow the engine to run at high RPM without a load. Doing so could damage the engine.
NEVER operate a unit with worn or dam- aged fasteners or attachment holders.
NEVER operate the unit with the cutting at- tachment shield or other protective devices removed!
Shoulder Strap
Adjust the shoulder strap so the shoulder pad rests comfortably on the
T231
NOTE:
Although a shoulder strap accessory is not required for use with a grass trimmer, a shoulder strap can increase operator com- fort during extended periods of operation. See Figure 23.
