Move On/Off lever to “ON” position, pull recoil starter and
choke as required to start engine.
Make sure the transport wheels are in the down position
(tines not touching ground), slowly pull back on clutch
handle and transport aerator to work area.
Upon reaching the work area, release clutch control han-
dle, push down on height control handle lowering aerat-
ing tines to the turf.
Pull back slowly on the clutch handle to start aerating.
For maximum tine penetration into turf, apply downward
pressure on handle.
At the end of aerating run, release clutch handle and lift
up on height control handle. Apply just enough pressure
on clutch handle to aid in turning aerator around and
repeat aerating pass.
When finished aerating, lift up on height control handle to
move wheels into transport position.
Drain water tank when finished with aerating.
SERVICE
WARNING
!
•
When replacement parts are required, use genu-
ine RYAN parts or parts with equivalent charac-
teristics including type, strength, and material.
Failure to do so may result in product malfunc-
tion and possible injury to the operator and/or
bystanders.
•
Any warning decal that becomes illegible should
be replaced immediately.
•
Do not operate equipment without shields in
place. Do not make any adjustments or perform
any maintenance while the engine is running.
Thoroughly clean all tines inside and out when aerating is
completed and apply a light coat of oil to prevent rust on
tines.
Check engine and gear reduction case oil level with
engine resting in a level position.
Inspect air filter element and replace if necessary.
Wipe off lubrication fittings before and after each lubrica-
tion. Always lubricate aerator each time it is put into ser-
vice.
Keep drive belt free of oil and dirt.
Check roller chains for tightness and wear. Apply a light
coat of no. 30 oil or penetrating chain lubricant to keep
the chain clean and in proper running order.
Idler sprockets are adjustable. Loosen nut and screw
holding idler sprocket to frame then slide sprocket in slot
to desired position. Tighten hardware.
NOTICE
•
Excessive roller chain tightness will shorten the life of
the bearings. Chain should have movement of 1/8
″
to 1/4
″
(3mm to 6mm) up and down at center point
between both sprockets.
STORAGE INSTRUCTIONS
WARNING
!
•
To prevent possible explosion or ignition of
vaporized fuel, do not store equipment with fuel
in tank or carburetor in enclosure with open
flame. (Example: Furnace or water heater pilot
light).
Before the equipment is put into storage for any period
exceeding 30 days, the following steps should be taken:
1. Drain all fuel from fuel tanks and fuel lines.
2. Start engine and run until all fuel is used from carbu-
retor float bowl.
3. While engine is still warm, drain the crankcase oil
and replace with the proper weight oil corresponding
to the season the equipment will next be used.
4. Remove the spark plug and squirt a small quantity of
engine oil into the cylinder. Turn the engine over a
few times to distribute that oil.
5. Drain water tank.
6. Lubricate all lubrication fittings.
To put equipment into operation after an extended stor-
age:
1. Check for loose parts and tighten if necessary.
2. Check for cracked or broken tines and replace.
3. Fill fuel tank.
4. Check engine and gear reduction case oil levels
(with engine in a level position).
5. Start engine.
6. Check for fuel leaks.
7. Check clutch lever operation to make sure unit stops
when lever is released.
