OPERATIONAL SAFETY
SAFETY PRECAUTIONS
TRAINING
1. Carefully read and follow all caution decals.
(See Pg. 5.)
2. Operate only in daylight or good artificial light.
1. Regard the unit as a piece of power equipment and
teach this regard to all who operate this unit.
3. Do not operate machine unless all guards, shields and
covers are in place and in proper working condition.
2. Read the instructions carefully. Be familiar with the
controls and the proper use of the equipment.
4. It is essential all operator safety mechanisms be
connected and in operating condition prior to use.
3. Never allow children, teenagers or people unfamiliar
with these instructions to use this piece of equipment.
5. Do not change the engine governor settings or over-
speed the engine. Operating an engine at excessive
speed may increase the hazard of personal injury.
4. Avoid operating unit while people, especially children
or pets, are nearby. Keep in mind that the operator or
user is responsible for accidents or hazards occurring
to other people or their property.
6. Disengage the drive control(s) and tine lowering
handle before starting. (See Pg. 3, Fig 1.)
7. Start the engine carefully with feet well away from
the tines.
5. Be sure you know how to stop the Aerator at a
moments notice.
8. Do not put hands, feet or clothing near rotating parts
while the unit is being operated.
PREPARATION SAFETY
1. The use of personal protective equipment, such as (but
not limited to) protection for the eyes, ears, feet and
head is recommended.
9. Travel up and down slopes at a 45 degree angle rather
than across, to prevent unit from tipping over.
10. Exercise extreme caution when changing direction on
slopes. Do not get too close to sharp drop-offs or
operate unit on excessively steep slopes. DO NOT
release control handle(s) on a slope, this will cause
free wheeling, allowing unit to roll back down the
slope. Make sure to leave yourself room to correct the
problem if one arises.
2. While operating, always wear substantial foot wear
and long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
3. Area should be free of all obstacles and debris.
ENGINE SAFETY
1. Handle gasoline with care; it is highly flammable.
2. Use an approved gasoline container.
3. Always add fuel before starting the engine.
4. Fill the fuel tank outdoors.
11. Use caution when pulling the unit towards you.
12. Always stop the tines if unit has to be tilted for
transportation or when crossing surfaces (i.e.
sidewalks, driveways, stepping stones, etc.).
5. If fuel is spilled, do not attempt to start the engine.
Move away from the area of the spill and avoid
creating any source of ignition until fuel vapors have
dissipated.
13. Never pick up or carry an Aerator while the engine
is running.
14. Stop the engine and disconnect the spark plug wire:
a) before checking, cleaning or working on unit, and
b) after striking a foreign object (inspect the unit for
damage and make repairs before restarting and
operating).
WARNING
DO NOT FILL TANK COMPLETELY FULL.
DO NOT SMOKE WHILE YOU FILL FUEL TANK.
15. Stop the engine: a) whenever you leave the unit,
b) before refueling, and c) before clearing blockages.
DO NOT REMOVE GAS CAP IF ENGINE
IS RUNNING.
16. Reduce the throttle setting during engine run-out and,
if the engine is provided with shut-off valve, turn the
fuel off at the conclusion of operating.
DO NOT OPERATE ENGINE IN A
CONFINED SPACE WHERE DANGEROUS
CARBON MONOXIDE FUMES CAN COLLECT.

TO OPERATE AERATOR
OPERATION
1. Start engine. (See “Starting Engine” section.)
PREPARATION
WARNING
1. Carefully read this manual and operate
Aerator correctly.
CAUTION: TO AVOID INJURY, DO NOT PLACE
FEET OR OTHER BODY PARTS UNDER TINES
WHILE STARTING THE ENGINE.
2. Always check machine on level ground.
3. Visually check all moving parts and all fasteners, if
loose or broken, tighten or replace. Check for broken
or bent tines, replace if necessary.
2. Make sure the rear tires are in the down position
(tines not touching ground). Slowly pull back on
control handle(s). (See Fig. 1.)
4. Lubricate all fittings after every four hours of using
machine, using a pressurized gun with standard
lithium base lubricant (see “General Maintenance”
section). Wipe off fittings before and after lubricating.
Control Handle (Left Side)
5. Check engine crankcase and gear reduction case oil
levels with engine resting in a level position. Add oil
if necessary. (Refer to engine manufacturer’s owners
manual for the correct type and amount of oil.)
6. Fill the fuel tank according to engine
manufacturer specifications.
7. For best performance and maximum tine penetration,
thoroughly water lawn the day before aeration.
8. Police lawn area for obstacles and debris (i.e.
sprinklers, hoses, toys, etc.)
Lowering Handle
Fig. 1
9. Mark underground sprinkler heads and other hidden
obstacles to prevent damage.
3. Move Aerator to the work area. (See “Transporting
Aerator” section.)
STARTING ENGINE
4. Upon reaching the work area, release control
handle(s) and push down on lowering handle
(see Fig. 1) putting tines in the turf.
WARNING
5. Pull back slowly on the control handle(s) to
begin aerating.
CAUTION: TO AVOID INJURY, DO NOT PLACE
YOUR FEET OR OTHER BODY PARTS UNDER
THE TINES WHILE STARTING THE ENGINE.
6. For maximum tine penetration into turf, apply
downward pressure on handle.
7. Models CA-18, TA-19D & TA-26D: At the end of
aerating run, release control handle and lift up on
lowering handle. Turn Aerator around and repeat
steps 5 and 6.
1. Turn fuel cock to the “open” position.
2. Turn choke on (closed).
3. Turn ignition switch to “on”.
4. Pull recoil starter rope until engine starts.
5. After engine is warm, turn off choke (open).
6. Allow engine to run one minute before operating.

control handles designed so it can be steered around
corners, obstacles, etc. By pulling back only the left
control handle, the Aerator will turn left, by pulling
back only the right control handle, unit will turn right.
Pull both control handles back to go straight.
7. Check engine rpm setting before operating. DO NOT
exceed 3600 rpm.
TRANSPORTING AERATOR
9. When finished aerating, lift up on lowering handle to
move wheels into transport position. (See
“Transporting Aerator” section.)
