Operating Precautions
■ This Shindaiwa tiller/cultivator attachment is specifically designed for use on Shindaiwa
PowerBroom and Trimmers.
Installation and/or use on any other model, brand or type of power tool is not approved by
Shindaiwa. Attempts to use on non-approved models can damage the equipment and cause accidents, serious injury or death.
■ Always make sure the Tiller/
Cultivator attachment is properly installed and firmly tightened before operation.
■ Never use a cracked or warped tine: replace it with a serviceable one and make sure it fits properly.
■ Never smoke or light fires near the engine. Fuel is very flammable and fire could lead to serious personal injury or property damage.
■ Make sure there are no missing or loose fasteners, and that the stop switch and throttle controls are working properly.
WARNING!
■ Make sure there is always good ventilation when operating this unit. Fumes from engine exhaust can cause serious injury or death. Never run the engine indoors!
■ Before starting the engine, make sure the tines are not contacting anything.
■ Always 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.
■ Stop the engine immediately if the unit suddenly begins to vibrate or shake. Inspect for broken, missing or improperly installed parts or attachments.
■ Never transport the unit or set it down with the engine running. An engine that’s running could be accidentally accelerated causing the tines to rotate.
CAUTION!
Always keep the unit as clean as practical. Keep it free of loose vegetation, mud, etc.

Operation
Starting and Fueling
For detailed instructions on general safety procedures, fueling, starting, and stopping the Shindaiwa
PowerBroom or Trimmer, refer to the appropriate Owner’s Manual for your model.
WARNING!
KEEP CLEAR of tines during starting operations! The tines may rotate during startup.
General Operation
Your Shindaiwa Tiller/Cultivator's reversible tines allow you to quickly change from operation as a cultivatorweeder to an aggressive tiller for quickly digging a new garden or landscaping plot. For best operation in either mode:
WATER the area to be tilled at least
24 hours before your planned tilling operation; then water again about 3 hours before the actual tilling.
PULL the tiller slowly toward you when tilling or cultivating.
FOR DEEP TILLING (up to 10" depth) use full throttle while slowly rocking the tiller back and forth over the work area.
SHALLOW WEEDING in soft soils is easiest when the tines are installed in the cultivating configuration, with additional depth available by using a gentle rocking motion as described above.
HEAVY WEEDS or weeding in harder soils may require reversing the tines to the more aggressive tiller configuration.
WARNING!
BURN DANGER! The gearcase will become very hot during normal operation.
16
Checking Unit Condition
NEVER operate the unit with the debris shield or other protective devices (ignition switch, etc.) removed!
Shoulder Strap
NOTE:
Although a shoulder strap accessory is not required for use with a Tiller/
Cultivator, a shoulder strap can increase operator comfort during extended periods of operation.
See Figure 16.
WARNING!
A debris 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 machine. Do not make modifications without the written approval of
Shindaiwa Inc.
NEVER use a cracked or warped tine: replace it with a serviceable one.
ALWAYS 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.
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.
