Using A Brushcutter Blade T272X

WARNING!

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

NEVER use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage.

NEVER use a blade for purposes other than those for which it was designed.

Whenever you strike a hard ob- ject with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPER-

ATE THE UNIT WITH A DAMAGED BLADE!

A blade-equipped unit must be equipped with a bicycle-type handle- bar or barrier bar as well as a har- ness or shoulder strap.

ALWAYS make sure the cutting at- tachment shield is properly installed before operating this unit.

Blade Thrust

‘Blade thrust’ is a sudden sideways or backward motion of the brushcutter. 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!

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 protec- tion against blade thrust. Plus, a shoulder strap gives significant support 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 operator using the unit.

Engine Operating Speeds

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

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

Avoid 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.

Using A Brushcutter Blade T272X

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 be- tween the blade’s 8 o’clock and 10 o’clock positions (as viewed from above). DO NOT cut between the 10 o’clock and 5 o’clock positions. See Figure 25.

WARNING!

When cutting wood with a blade, feed the blade slowly. Never strike or “slam” the spinning blade against the wood.

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

Vertical Cuts

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

Move the blade from top to bottom through the cut, and cut only with the bottom edge of the blade. See Figure 26.

Cut on the left side of the blade.

KEEP YOUR BODY OUTSIDE THE PATH OF BLADE ROTATION

WARNING!

When making vertical cuts, never allow the blade to exceed waist height.
