SPEED
It is recommended for proper aerating performance that the engine be operated at maximum RPM. Control ground
speed using the forward/reverse drive levers. Speed is proportional to the extent the levers are actuated.
TINES RAISING/LOWERING
The tines are raised or lowered into the ground by operating the tine engagement lever on the right of the machine.
When engaging the ground, be sure that lever cams over and locks into place. Tine penetration is very dependent on
surface preparation. When removing the tines from the engagement position, make sure the lever fully cams over into
the forward position for transport. READ the entire operation section before aerating.
AERATING OPERATION
MOW: Mow the lawn to its normal cut height.
WATER: For the best performance and maximum tine penetration the lawn should be thoroughly watered the day
before aeration.
INSPECT lawn before beginning work. Remove all rocks, wire, string, or other objects that can present a hazard
during work prior to starting.
IDENTIFY and mark all fixed objects to be avoided during work, such as sprinkler heads, water valves, buried cables,
or clothes line anchors, etc.
START ENGINE: See Safety and General Operation manual.
ENGAGE TINES: With the aerator in the work area, lower the tines into the ground with the tine lowering lever and engage the
tine lever on the left hand side of the handle.
AERATE: With the tines engaged, engage either the forward or reverse drive lever for the desired direction of travel. Note: Core
spacing on this machine is determined by speed. The faster you travel the further the spacing between cores pulled and vice
versa. NOTE: The hydraulic system may seem sluggish until the oil reaches a normal operating temperature.
TRANSPORT: Be sure to lift the tine engagement lever (tines out of the ground) before transporting away from the work area.
AERATING TIPS
WATER: For the best performance and maximum tine penetration, the lawn should be thoroughly watered the day before
aeration.
SLOPES: Do not operate the aerator on steep slopes. Use extreme caution when operating on any sloped surface. For lesser
sloped areas operate the unit, traversing up and down at a 45 degree angle to the slope rather than straight across. Extended
operation on steep slopes can cause engine damage.
NOTE: DO NOT release the operators clutch bail when operating on a slope. This will allow the unit to free wheel and allow the
unit to roll down the slope.
NOTE: Honda engines are equipped with a low oil sensor to prevent engine damage. When it senses a low oil condition (i.e.
unit is operating or sitting on a steep slope) the engine shuts down. The maximum operating slope for the engine is 200. The low
oil condition must be corrected before the engine can be restarted. See the engine owner’s manual for more information.
PARKING
NEVER PARK THIS UNIT ON A SLOPE OF ANY KIND. Always keep tines in the up position when parking the unit.
