Using A Brushcutter Blade T272X

OPERATION

WARNING!

nBefore working with a blade- equipped unit, always inspect and clean the area of objects that could interfere with or damage the blade.

nNever use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage.

nNever use a blade for purposes other than those for which it was designed.

nWhenever you strike a hard object with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPERATE THE UNIT WITH A DAMAGED BLADE!

nA blade-equipped unit must be equipped with a bicycle-type handlebar or barrier bar as well as a harness or shoulder strap.

nAlways make sure the cutting attachment shield is properly installed before operating this unit.

The blade rotates counter-clockwise. For best performance and to minimize being stuck by debris, move the blade from right to left while advancing on your work.

Position the blade so cuts are made between the blade’s 7 o’clock and 11 o’clock positions (as viewed from above). DO NOT cut between the 11 o’clock and 5 o’clock posi- tions. See Figure 25.

Rotation

OK To Cut

Blade Thrust

‘Blade thrust’ is a sudden sideways or backward motion of the brushcut- ter. Such motion may occur when the blade jams or catches on an object such as a sapling tree or tree stump. BE CONSTANTLY ALERT FOR BLADE THRUST AND GUARD AGAINST ITS EFFECTS!

WARNING!

nWhen cutting wood with a blade, feed the blade slowly.

Never strike or “slam” the spin- ning blade against the wood.

nDO NOT use 2-tooth or non- Shindaiwa approved 4-tooth cutting blades with Shindaiwa trimmers and brushcutters.

Brushcutter Handlebar

A brushcutter’s handlebar helps prevent the operator from moving forward or the unit moving rearward; thus preventing inadvertent bodily contact with the blade. ALWAYS KEEP THE HANDLEBAR SECURELY IN PLACE ON THE UNIT!

Shoulder Strap

A shoulder strap provides additional protection against blade thrust. Plus, a shoulder strap gives signiﬁcant sup- port and comfort to help ensure safe and efﬁcient operation.

When operating a blade equipped trimmer, make sure the shoulder strap is adjusted properly to the op- erator using the unit.

Engine Operating Speeds

Operate the unit at full throttle while cutting. Best fuel efﬁciency is obtained by releasing the throttle when swinging back after a cut.

nTo prevent possible engine damage, do not allow the brushcutter to operate at high speeds without a load.

nAvoid cutting at low engine speeds. Do- ing so can lead to rapid clutch wear. In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting attachment.

Vertical cuts

Hold the trimmer with the blade at a 90° angle to the ground so the blade’s bottom edge rotates toward the opera- tor.

Move the blade from top to bottom through the cut, and cut only with the bottom edge of the blade.

WARNING!

When making vertical cuts, never al- low the blade to exceed waist height.

Cut on the left side of the blade. KEEP YOUR BODY OUT- SIDE THE PATH OF BLADE ROTATION
