5.3 OPERATING PROCEDURES_________________________________________________
1. Before starting engine, always release OPC handle.
2. Do not operate aerator or attachments with loose,
damaged or missing components.
3. First aerate in a test area to become thoroughly
familiar with the operation of the unit and control
levers.
4. Study the area to determine the best and safest
operating procedure. Consider the type of terrain,
and condition of the surface. Each condition will
require certain adjustments or precautions.
5. Never direct discharge of material toward
bystanders, nor allow anyone near the machine
while in operation. The owner/operator is
responsible for injuries inflicted to bystanders and/or
damage to their property.
6. Use discretion when operating near gravel areas
(roadway, parking areas, cart paths, etc.). Stones
struck by the unit may cause serious injuries to
bystanders and/or damage the equipment.
7. Always raise aerator head and move control lever
out of L position when not aerating.
8. Disengage the tines and raise the aerator head
when crossing paths or roadways. Look out for
traffic.
9. Stop and inspect the equipment for damage
immediately after striking an obstruction or if the
machine begins to vibrate abnormally. Have the
equipment repaired before resuming operation.

Section 5.7. Use caution when operating near drop
offs.
11. Use care when approaching blind corners, shrubs,
tress or other objects that may obscure vision.
