Physical Condition
Your judgment and physical dexterity may not be good:
• if you are sick,
• if you are taking medication,
• if you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Eye Protection
Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your grip on the handles. Gloves also reduce the transmission of ma-
chine vibration to your hands.
Hearing Protection
Shindaiwa recommends wearing hearing protection whenever unit is used.
Proper Clothing
Wear snug tting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• Wear hair covering to contain long hair.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or hanging items that could become entangled
in moving parts or surrounding growth.Wear sturdy work shoes with non-skid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Keep long hair away from engine and air intake. Retain hair with cap or net.
Hot Humid Weather
Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early
morning or late afternoon hours when temperatures are cooler.
Vibration and Cold --
It is believed that a condition called Raynaud’s Phenomenon, which affects the ngers of certain individuals may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sen-
sations followed by loss of color and numbness in the ngers. The following precautions are strongly recommended
because the minimum exposure which might trigger the ailment is unknown.
• Keep your body warm, especially the head, neck, feet, ankles,
hands and wrists.
• Maintain good blood circulation by performing vigorous arm exer-
cises during frequent work breaks and also by not smoking.
• Limit the hours of operation. Try to ll each day with jobs where
operating the unit or other hand-held power equipment is not
required.
• If you experience discomfort, redness, and swelling of the ngers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.

Repetitive Stress Injuries --
It is believed that overusing the muscles and tendons of the ngers, hands, arms, and shoulders may cause soreness,
swelling, numbness, weakness, and extreme pain in those areas. Certain repetitive hand activities may put you at a high
risk for developing a Repetitive Stress Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome (CTS), which
could occur when your wrist swells and squeezes a vital nerve that runs through the area. Some believe that prolonged
exposure to vibration may contribute to CTS. CTS can cause severe pain for months or even years.
To reduce the risk of RSI/CTS, do the following:
• Avoid using your wrist in a bent, extended or twisted position. In-
stead try to maintain a straight wrist position. Also, when grasping,
use your whole hand, not just the thumb and index nger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force in which you do the repetitive move-
ment.
• Do exercises to strengthen the hand and arm muscles.
• See a doctor if you feel tingling, numbness or pain in the ngers,
hands, wrists or arms. The sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle damage can be prevented.
DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
Read the Manuals
• Provide all users of this equipment with the Operator’s Manual and
Safety Manual for instructions on Safe Operation.
Clear the Work Area
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while the
unit is in use.
Keep a Firm Grip
• Hold the front and rear handles with both hands, with thumbs and
ngers encircling the handles.
Keep a Solid Stance
• Maintain footing and balance at all times. Do not stand on slippery,
uneven or unstable surfaces. Do not work in odd positions or on lad-
ders. Do not over reach.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact during
and immediately after operation.

Operating Techniques
1. The tilling width of the cultivator is approximately 165 mm (6.5
in.). Place cultivator in area to be tilled, hold unit rmly with left
hand on front grip and right hand on rear grip and gradually engage
throttle trigger. Guide the cultivator allowing the tines to pull
forward. The soil hardness will control tilling speed.
WARNING
Moving parts can amputate ngers or cause severe injuries. Keep hands, clothing and loose objects away from all
openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete
stop before removing obstructions, clearing debris, or servicing unit. Allow unit to cool before performing service.
Wear gloves to protect hands from sharp edges and hot surfaces.

3. To raise or aerate the soil, tilt engine closer to the ground which
will raise cultivator tines higher relative to the soil surface.
IMPORTANT
Do not operate cultivator underwater. The gear housing is not
sealed and water will wash away lubrication, damaging gears,
bearings, and seals.
A
resettIng tInes for deep CultIvatIon
Tools Required: 10 mm Wrench
The tines are factory assembled with blade ends offset for standard cul-
tivation. For deep cultivation, the left tine (viewed from the operator's
position) must be repositioned on the hub aligning the left and right tine
blade ends directly across from each other.
1. Remove three (3) bolts (A) mounting left tine to hub. The bolts
will be mounted in hole labeled (1).
2. The cultivator attachment is capable of tilling in the forward or
reverse direction. For deep soil tilling, till forward then lightly pull
unit rearward allowing the tines to make a deeper cut into the soil.
Deep soil cultivating can also be enhanced by repositioning the
tines. (Refer to Tine Setting).
