Safety
DANGER
Operating on wet grass or steep slopes can cause
sliding and loss of control. Wheels dropping over
edges, ditches, steep banks, or water can cause
rollovers, which may result in serious injury,
death or drowning.
• Do Not operate on slopes when grass is wet.
• Do Not operate near drop-offs or near water.
• Do Not operate on slopes greater than 15
degrees.
• Reduce speed and use extreme caution on
slopes.
• Avoid sudden turns or rapid speed changes.
• Reduce tine down pressure to prevent the drive
tires from raising off the ground and to prevent
the front tires from raising off of the ground
while aerating uphill.
• See inside the back cover to determine the
approximate slope angle of the area to be aerated.
• Remove or mark obstacles such as rocks, tree
limbs, etc. from the working area. Tall grass can
hide obstacles.
• Watch for ditches, holes, rocks, dips and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Avoid sudden starts when aerating uphill because
the machine may tip backwards. The machine is
more stable going uphill with the tines disengaged.
• Be aware that operating on wet grass, across steep
slopes or downhill may cause the machine to lose
traction. Loss of traction to the drive wheels may
result in sliding and a loss of braking and steering.
• Always avoid sudden starting or stopping on a
slope.
• Follow the manufacturer's recommendations for
wheel weights or counter weights to improve
stability.
• Use extreme care with attachments. These can
change the stability of the machine and cause loss
of control.
Maintenance and Storage
• Raise the tines, set the parking brake, stop engine
and remove key or disconnect spark plug wire.
Wait for all movement to stop before adjusting,
cleaning or repairing.
• Keep engine and engine area free from excessive
grease or oil and other debris which can
accumulate in these areas. These materials can
become combustible and may result in a fire.
• Let engine cool before storing and do not store
near flame or any enclosed area where open pilot
lights or heat appliances are present.
• Shut off fuel while storing or transporting. Do
Not store fuel near flames or drain indoors.
• Park machine on level, hard ground. Never allow
untrained personnel to service machine.
• Use jack stands to support components when
required.
• Carefully release pressure from components with
stored energy.
• Disconnect battery or remove spark plug wire
before making any repairs. Disconnect the
negative terminal first and the positive last.
Reconnect positive first and negative last.
• Use care when checking and servicing tines. Wrap
the tine(s) or wear gloves, and use caution when
servicing them. Only replace damaged tines.
Never straighten or weld them.
• Keep hands and feet away from moving parts.
If possible, do not make adjustments with the
engine running.
• Charge batteries in an open well ventilated area,
away from spark and flames. Unplug charger
before connecting or disconnecting from battery.
Wear protective clothing and use insulated tools.
DANGER
Charging or jump starting the battery may
produce explosive gases. Battery gases can
explode causing serious injury.
• Keep sparks, flames, or cigarettes away
from battery.
• Ventilate when charging or using battery
in an enclosed space.
• Make sure venting path of battery is
always open once battery is filled with
acid.
• Always shield eyes and face from battery.
