Checking Unit Condition, Shoulder Strap | Shindaiwa 81642 instruction

Checking Unit Condition

Use only authorized Shindaiwa parts and ac- cessories with your Shindaiwa trimmer. Do not make modifications to this unit without written approval from Shindaiwa, Inc.

WARNING!

A cutting attachment shield or other protective device is no guarantee of protection against ric-

ochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!

Shoulder Strap

nALWAYS make sure the cutting attach- ment is properly installed and firmly tightened before operation.

nNEVER use a cracked or warped cutting attachment: replace it with a serviceable one.

nALWAYS 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.

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

nNEVER allow the engine to run at high RPM without a load. Doing so could dam- age the engine.

nNEVER operate a unit with worn or dam- aged fasteners or attachment holders.

nNEVER operate the unit with the cutting attachment shield or other protective devices removed!

Adjust the shoulder strap so the shoulder pad rests comfortably on the off-side shoulder and the cutting path of the cut- ting attachment is parallel to the ground. Make sure all hooks and adjustment devices are secure.

NOTE:

Although a shoulder strap accessory is not required for use with a grass trimmer, a shoulder strap can increase operator com- fort during extended periods of operation. See Figure 23.

Cutting Grass—Units Equipped with a Trimmer Head

Your Shindaiwa unit may be equipped with one of several Shindaiwa trimmer head mod- els, each with features for specific applica- tions 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 manually 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 clear- ing 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 exces- sive 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 24.

Edging

Tilt the handle about 100° to the left (from horizontal) and move forward, holding the trimmer vertically as shown in Figure 25.
