Shindaiwa 81644 manual Checking Unit Condition, Shoulder Strap C242

Checking Unit Condition

NEVER operate the unit with the cut- ting attachment shield or other protective devices removed!

WARNING!

A cutting attachment shield or other protective device is no guarantee of protection against ricochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!

Use only authorized Shindaiwa parts and accessories with your Shindaiwa trimmer.

Do not make modifications to this unit with- out written approval from 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 attachment holder. If a properly installed attachment vibrates, replace the attach- ment with new one and re-check.

ALWAYS stop the engine immediately and check for damage if you strike a for- eign object or if the unit becomes tangled. Do not operate with broken or damaged equipment.

NEVER allow the engine to run at high RPM without a load. Doing so could damage the engine.

NEVER operate a unit with worn or damaged fasteners or attachment holders.

Shoulder Strap C242

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.

WARNING!
Always wear a shoulder strap
or harness when operating this unit. Us-
ing a harness with a brushcutter allows
you to maintain proper control of the unit
and reduces fatigue during extended
operation.	Figure 21

Cutting Grass—Units equipped 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. Available trimmer head styles include:

nSemi-automatic. Trimmer line is indexed when the operator taps the trimmer head on the ground during operation.

nManual. The operator indexes line man- ually with the grass trimmer stopped.

nFixed. The operator must stop the unit and add new lengths of trimmer line manually.

nFlail. 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 trim- mer heads.

CAUTION!

Do not push the rotating line into trees, wire fences or any material that could tangle or break line ends.

Engine Operating Speeds

Operate the unit at full throttle while cut- ting grass.

CAUTION!

Operation of trimmer without a cutting attachment shield and using excessive line length can lead to premature clutch failure.

CAUTION!

Operation at low RPM can lead to premature clutch failure.

Hold the 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 trimmer from left to right. Keep the trimmer head horizontal. See Figure 22.
