Tips
• 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 - Check the lawn before beginning work. Remove all rocks, wire, string, or other objects that can
present a hazard during work prior to starting
• Identify - Mark all fixed objects to be avoided during work, such as sprinkler heads, water valves, buried
cables, or clothes line anchors, etc.
• Slopes - Do not operate the aerator on steep slopes (any slope exceeding 15°). Use extreme caution
when operating on any sloped surface. For lesser sloped areas operate the unit, traversing up and down at
a 45° angle to the slope rather than straight across. Extended operation on steep slopes can cause engine
damage.
