Check Unit Condition
NEVER operate the unit with the cutting at- tachment shield or other protective devices (harness, ignition switch, blade retention clip, etc.) removed!
WARNING!
A cutting attachment shield or other protective device is no guarantee of protection against thrown objects. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!
Use only authorized Shindaiwa parts and accessories with your Shindaiwa trimmer or brushcutter. Do not make modifications to the unit without the written approval of Shindaiwa, Inc.
ALWAYS make sure the cutting attach- ment is properly installed and firmly tight- ened before operation.
NEVER use a cracked or warped cutting attachment: replace it with a serviceable one.
ALWAYS make sure the cutting attach- ment fits properly into the appropriate cutter holder. If a properly installed attach- ment vibrates, replace the attachment with a 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 equip- ment.
NEVER allow the engine to operate at high RPM’s without a load. Doing so could dam- age the engine.
NEVER operate a unit with worn or dam- aged fasteners or attachment holders.
NEVER cut with dull blades. Doing so will increase the risk of blade thrust and may also damage your equipment.

IMPORTANT!
Adjust the shoulder strap or harness so the shoulder pad rests comfortably on the
T272
NOTE:
Although a shoulder strap accessory is not required for use with a grass trimmer, a shoulder strap can increase operator comfort during extended periods of operation.

Trimming and Mowing Grass

unit and add new lengths of trimmer line manually.
