Operation
Shoulder strap
WARNING!
Always wear a shoulder strap or harness when operating this unit. Using a harness with a brushcutter allows you to maintain proper control of the unit and reduces fatigue during extended operation.
IMPORTANT!
Adjust the shoulder strap so the shoul­der pad rests comfortably on the off-side shoulder and the cutting path of the cut­ting attachment is parallel to the ground. Make sure all hooks and adjustment devices are secure.
Shoulder strap
required for use
with Brushcutters
Hook the strap hook to the hanger on 1. the outer tube.
Wear the shoulder strap so that the 2. hook stays at your right hand side.
Adjust the length of the shoulder strap 3. so that you can hold and operate the machine comfortably.
Cutting grass with a trimmer head
Your Shindaiwa unit may be equipped with one of several Shindaiwa trimmer head mod­els, each with features for specific applica­tions and/or operational requirements.
NOTE:
For proper operation, always refer to the instructions accompanying the trimmer head being used.
Trimmer head styles:
Semi-automatic. Trimmer line is indexed when the operator taps the trimmer head on the ground during operation.
Manual. The operator indexes line manu­ally with the grass trimmer stopped.
Fixed. The operator must stop the unit and add new lengths of trimmer line manually.
Flail. This device, designed for clear­ing weeds and light brush, features three nylon blades attached to the head by pivots.
NOTE:
Additional hardware may be required to mount the Fixed Line or the Flail type trimmer heads.
NOTE:
Using a shoulder strap when operating this unit with a blade allows you to main­tain proper control of the unit and reduces fatigue during extended operation.
Engine Operating Speeds
Operate at full throttle while cutting grass.
CAUTION!
Operation at low rpm can lead to pre­mature clutch failure.
Trimming and Mowing Grass
Hold the grass trimmer so the trimmer head is angled slightly into the area to be cut. To ensure maximum trimmer-line service life, cut only with the tip of the trimmer line. Cut grass by swinging the unit's trimmer head from left to right. Keep the trimmer head horizontal.
CAUTION!
Do not push the rotating line into trees, wire fences or any material that could tangle or break line ends.
CAUTION!

Using a blade
WARNING!
Before working with a blade-equipped Ŷ unit, always inspect and clean the area of objects that could interfere with or damage the blade.
Never use a blade near sidewalks,
Ŷ
fence posts, buildings or other objects that could cause injury or damage.
Never use a blade for purposes other
Ŷ
than those for which it was designed.
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
BE CONSTANTLY ALERT FOR
stump. BLADE THRUST AND GUARD AGAINST ITS EFFECTS!
WARNING!
Blade thrust can occur without warning if the blade snags, stalls or binds.
Whenever you strike a hard object
Ŷ
with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPER­ATE THE BRUSHCUTTER WITH A DAMAGED BLADE!
A blade-equipped unit must be
Ŷ
equipped with a bicycle-type handle­bar or barrier bar as well as a har­ness or shoulder strap.
Always make sure the cutting attach-
Ŷ
ment shield is properly installed before operating this unit.
WARNING!
Blade thrust is more likely to
RFFXULQDUHDVZKHUHLWLVGLI¿FXOWWR
see the material being cut.
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!
Brushcutter Shoulder Strap
A shoulder strap provides additional pro­tection against blade thrust. In addition, 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 by releasing the throttle when swinging back after a cut.
To prevent possible engine damage, do Ŷ 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
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 o’clock and 5 o’clock positions.
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 non­Shindaiwa 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 opera­tor. 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 allow the blade to exceed waist height.
Cut on the left side of the blade. KEEP YOUR BODY OUTSIDE THE PATH OF BLADE ROTATION

Make sure nuts, bolts, and screws (except carburetor adjusting screws) are tight.
Blades
Keep blades sharp and check blade condition frequently. If a blade’s per­formance changes suddenly, stop the engine and check the blade for cracks or other damage. Replace a damaged blade IMMEDIATELY!
WARNING!
Ŷ
Never repair a damaged blade by welding, straightening, or by modify­ing its shape. An altered blade may break during operation, resulting in serious personal injury.
DO NOT use 2-tooth or NON-Shin-
Ŷ
daiwa approved 4-tooth cutting blades on Shindaiwa trimmers or brushcutters.
Blades are not interchangeable
Ŷ
between Shindaiwa edgers and trimmer/brushcutter models. Oper­ating any unit with a blade or attachment not approved for that unit can be hazardous and may cause serious injury.
Daily maintenance
Prior to each work day, perform the following:
Remove all dirt and debris from the
Ŷ
engine, check the cooling fins and air cleaner for clogging, and clean as necessary.
Carefully remove any accumulations
Ŷ
of dirt or debris from the muffler and fuel tank. Check cooling air intake area at base of crankcase. Remove all debris. Dirt build-up in these areas can lead to engine overheating, fire, or premature wear.
