Introduction Thank you for purchasing the Air Force Hover Mower. The following pages are to give you information about maintenance, operation, safety and specifications instructions regarding your new mower. We strongly recommend reading the manual before your first use. Important: Familiarize yourself with all controls, operations and regular maintenance points before your first use. If you require clarification, please consult your local Authorized Dealer who can assist you further.

The engine carries a 90 day commercial warranty. To qualify for the full benefit of the Air Force warranty, the warranty registration card must be returned to the distributor.
Safety Symbols Manual: Read the instruction manual before using machine. Use the Manual: Refer to the manual when making any adjustments or repairs to the machine. Spark Plug: Disconnect the spark plug when doing any work on the machine. Hot Surface: Be aware of the hot surfaces of your machine during and after use. Protective Gear: Always wear protective ear and eye gear when operating the machine.
Safety Precautions Your machine is perfectly safe if used correctly. Failure to observe the following precautions may result in serious injury. Training Read the Owner’s Manual and other informational material that came with your new mower. If the operator or mechanic cannot read English, it is the owner’s responsibility to explain this material to them. Become familiar with the safe operation of the mower, operator controls, and safety signs. All operators and mechanics should be trained.
Safety Precautions Use extra care when handling gasoline and other flammable fuels. Vapors are explosive. (a) Use only approved fuel containers (b) Never remove fuel cap or add fuel when the engine is operating (c) DO NOT SMOKE while operating the machine (d) Never refuel or drain the machine indoors (e) Always use fresh non-ethanol fuel. Stale fuel can block the carburetor and cause leaks. Check that the Operator Presence Control (OPC) and safety switches are attached and functioning properly.
Safety Precautions Operate across the face of slopes, never up and down. Slow down and use extra care when making turns or changing direction on slopes. Be sure to travel in the recommended direction on slopes. Turf conditions can affect the machine’s stability. Use caution while operating near drop-offs. Never raise the deck with the blades in motion. Stop the engine before moving the machine across areas other than grass. Never operate without the safety guards in place.
Safety Precautions Park the machine on level ground. Never allow untrained persons to service the machine. Remove the spark plug before attempting any repairs. Never check for a spark when the spark plug is removed. Use an approved tester. Keep all parts in good working condition and all hardware tightened. Replace all worn or damaged decals. Always replace worn or faulty parts with genuine Air Force Hover Mower parts. Allow the engine to cool before storing in any enclosures.
Machine Assembly Assembling the Machine Step One: Lower Handlebar Assembly To fit the lower handle to both sides, align the holes (footstop on the right side) and insert the sleeves, bushes, bolts, washers and nuts as shown. (Uses Deck/Handle Kit AF1210) Step Two: Upper Handle Assembly To fit the upper handle on both sides, align the holes and fit the bolts and nuts.
Before Starting the Machine Prevent Engine Damage To prevent damage to the engine, the machine is shipped without any fluids. The engine must be filled with the correct grade of oil and fuel before starting the engine. Oil Level Check When checking the oil, keep the mower on a level surface. Remove the oil cap, and wipe the dipstick with a clean cloth. Reinsert the dipstick without screwing the cap back on, and remove it to check the oil level.

Operating the Machine Starting the Machine Step One: Turn the petcock to the “on” position. Step Two: Press primer bulb NO MORE than 3 times. Move choke to the closed position. Step Three: Release the handlebar from the footstop. Hold the OPC Bail Arm to the upper handle, place your foot on the right side of the deck and slightly tilt the machine toward you. This position ensures the fuel is beginning to circulate and makes cranking the engine easy.
Operating the Machine Cutting Flat Landscapes Begin at the edge of the lawn and mow in a straight line back and forth as you would with a regular walk behind machine. Caution: Never stand below or beside the machine while mowing an embankment. Always stand higher on the slope than the machine. Cutting Slopes and Banks Begin at the top and swing the machine from side to side while carefully and slowly moving down the slope. Keep the machine moving to reduce strain on the engine.
Machine and Engine Maintenance To prevent accidents, disconnect the spark plug whenever you are performing any maintenance procedures on the machine. Engine: Cleaning the Air Filter The air filter should be cleaned every 8 hours, more often when used in a dusty environment. Engine power will be reduced is it is not cleaned properly. Do not use the machine if there is no air filter or if the filter is damaged. Failure to properly maintain the filter will void the warranty.
Machine and Engine Maintenance Muffler Check the muffler often to make sure it is not loose, damaged or rusty. Do not use the machine until the muffler is repaired or replaced. **Before starting the engine, check the two muffler bolts (#21, AF921) are tight. Loose muffler or cylinder may cause engine fire. Oil Maintenance Before each use, check the oil level and ensure that a correct oil level is at the upper limit. Refer to the “Before Starting the Machine” section for instructions.
Machine Maintenance Maintaining the Cutting System The condition of the cutting system and supporting mounting system should be checked regularly for signs of wear or damage. A damaged cutting system will become out of balance and cause the machine to vibrate excessively. The cutting system could damage the deck, impeller and other pieces under the deck and lead to damage to the engine or the operator. DO NOT use a damaged / unbalanced cutting system.
Machine Maintenance Flexiblade Cutting System Replacement (1) Drain the fuel by running the engine dry (engine will stop). (2) Remove the spark plug lead and allow the engine to cool. (3) Turn the machine on its left-hand side (carburetor up). (4) Replace the old line with 10 inches of new line. Mower Storage To prevent engine damage, engines must be drained of fuel when being stored in excess of 30 days. Removing the fuel prevents gum from forming in the fuel system and essential carburetor parts.
Maintenance Schedule Service Schedule Before Each Use Every Use Every 5 Hours Every 20 Hours or Once a month Every 50 Hours Every 100 Hours Storage Over 30 Days and Winterized Storage Maintenance (1) Check the fuel and oil levels (2) Check blade system and tighten any loose bolts (3) Check air filter – ensure it is dry (4) Remove debris from the cutting system, impeller, and air intake area of engine CLEAN THE AIR FILTER (Replace if needed) (1) Clean the air filter (2) Inspect Plug (3) Sharpen cuttin
