Brushcutter Shoulder Strap

A shoulder strap provides additional protection against blade thrust. In addi- tion, a shoulder strap gives significant support and comfort to help ensure safe and efficient operation. When operating a unit with a blade, make sure both the handle and shoulder strap are adjusted to the size of the operator using the unit.

Engine Operating Speeds

Operate the unit at full throttle while cutting. Best fuel efficiency is obtained

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 handlebar or barrier bar helps prevent the operator from moving forward, or the unit moving rearward, thus preventing inadvertent bodily contact with the blade. ALWAYS KEEP THE HANDLEBAR OR BARRIER BAR SECURELY IN PLACE ON THE UNIT!

by releasing the throttle when swinging back after a cut.

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

■Avoid operating the engine at low speeds. Doing so can lead to rapid clutch wear. In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting head.

Using a Blade

WARNING!

Always wear a shoulder strap when operating this unit with a blade. A shoulder strap is also recommened when using trimmer line.

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 8 o’clock and 10 o’clock positions (as viewed from above). DO NOT cut between the 10

WARNING!

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

WARNING!

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

Vertical Cuts

Hold the brushcutter 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.
