Recognizing Safety Warnings Used In Manual
LOOK FOR THE SAFETY HAZARD WARNING SYMBOL
The symbol is used to alert the operator of safety hazards.
It is used in conjunction with the words DANGER, WARNING, and CAUTION.
“DANGER” identifies immediate hazards which will result in serious injury or death.
“WARNING” identifies potential hazards which could result in serious injury or death.
“CAUTION” identifies hazardous situations which may result in minor injury and/or could result in
damage or destruction of equipment.
WARNING CAUTION
DANGER
Safety on the job should always be a top priority.
Training and experience are important factors in the
safe operation of equipment. Please consider the
following information and realize that safe operation is
a matter of using common sense as it relates to the
machine, its maintenance, the operator, the training,
and the operating conditions. These are general
safety instructions that apply to most turf maintenance
equipment.
This list includes many, but not all, general
safety instructions as they relate to turf
equipment. Common sense must always be
used to determine the safest way to operate a
machine under specific conditions.
TRAINING:
Always read the manual, the decals, and the safety
warning decals before operating a machine for the first
time.
Always check the location and use of each control
before operating a machine for the first time.
Practice operating the machine in a safe area with no
obstructions until becoming familiar with the controls.
If you have questions, ask your supervisor or call the
factory.
CLOTHING:
Clothes should be snug fit. Loose fitting clothing is
hazardous because it may get caught in the mechanism
during service or operation.
Remove jewelry before operation. Jewelry may get
caught in the mechanism.
Wear shoes that will protect your feet. The protection
of leather shoes, boots, or steel toed safety shoes, is
required.
Hard Hat: A hard hat should be considered when using
equipment on a golf course. The danger of being hit
General Safety Practices
by a golf ball should be a major concern as well as
protection needed while operating under trees or
around obstacles.
Eye Protection: Safety glasses and/or face shields
should be worn when operating, as well as working in
close proximity to high speed rotary equipment. Watch
for rotary mowers, edgers, brush and string trimmers.
Rotary mowers can throw debris at speed up to 320
Km/h.
Hearing: If the noise level of the equipment is too loud,
use ear protection.
Do not use stereo headsets during operation. This is
a distraction that may lead to an accident. Headsets
also make it difficult to hear other people and other
equipment while operating the machine.
Gloves: Use gloves to protect your hands. Use gloves
when handling sharp or hazardous objects.
Respirators: When operating in dusty, windy
conditions, wear a respirator. This is also an important
consideration if operating equipment while spraying
chemicals and fertilizers.
THE OPERATOR:
The operator should never use a machine while under
the influence of alcohol or drugs.
The operator should be aware of the hazards of
working in the sun and should take proper precautions
to avoid heat stress and dehydration. Use sun screen
products when necessary.
The operator should never attempt to ride a machine
that is not designed for that propose. Do not allow
others to ride a machine that is not designed for
passengers.
Do not operate any equipment at unsafe speeds.
Speeds should be reduced when turning or operating
on slopes. The operator must use common sense to
determine a safe speed based on the equipment, the
load, the slope, the surface, and other conditions that
may affect safe operation.
SAFETY

™
5
The operator must be aware of the conditions around
the machine. Be careful to observe other people and
machines in the area.
Beware of slippery conditions. Wet turf can be
encountered on slopes, when turning or stopping, or
at higher speeds.
Keep hands and feet away from cutting devices and
drive components. Shut off the engine and remove the
key or spark plug wire when servicing cutting devices
or drive components.
Care should always be taken when mounting and
dismounting a riding machine. Prevent injuries and
falls by making sure the operator does not slip. Unless
it is an emergency, do not jump off a machine. Injury
may result when an operator’s foot slips trying to jump
from a machine.
If required to lift, an operator should ask for help if the
object is too heavy. The operator should lift with the
legs instead of the back. Care should be taken to avoid
twisting the back while lifting a heavy load.
Never allow children to operate the machine.
THE MACHINE:
Do not modify the machine in any manner. Always
check the machine to make sure it is in good working
order.
Do not place hands or feet near moving or rotating
parts. Check that all guards are functional and properly
installed. Do not operate a machine without all guards
installed.
Do not use your fingers or hands to check for leaks.
High pressure leaks can puncture the skin and force oil
into the body. This can cause severe injury or death.
Check to assure that all controls are in good operating
condition.
Do not overload machinery. The components
are designed for certain weights and capacities.
Overloading machine will cause unsafe conditions
Shut off the engine before servicing the machine.
Check machines on a level area. Machines on a slope
may roll when the engine is off.
Refer unfamiliar repairs and adjustments to mechanics
that have been trained to do them properly.
Replace decals that are damaged or illegible.
THE ENGINE:
Do not run the engine in an enclosed area. The
exhaust gases contain carbon monoxide, an odorless
and deadly poison. The engine exhaust from this
product contains chemicals known to the State of
California to cause cancer, birth defects or other
reproductive harm.
Do not refuel machines indoors or in an unventilated
area. Do not over fill. Do not add fuel while the machine
is hot because spilled fuel may cause a fire. Use
fresh gasoline. Stale fuel can gum the carburetor and
can cause leakage. Check the fuel lines and fittings
frequently for cracks and leaks.
Pull the starter cord slowly until resistance is felt. Then
pull the cord rapidly to avoid kickback and to prevent
hand or arm injury.
Do not remove the fuel tank cap or fill fuel tank while
the engine is hot or running. Allow the engine to cool
before refueling.
Do not operate the engine if gasoline is spilled. Do
not operate the engine when the smell of gasoline
is present or if any other explosive conditions exist.
Move the equipment away from the spill and avoid any
ignition until the gasoline has evaporated.
Do not store, spill, or use gasoline near an open
flame. Do not store, spill, or use gasoline near a stove,
furnace, water heater, or appliance that uses a pilot
light or can create sparks.
Do not choke the carburetor to stop the engine.
Whenever possible, gradually reduce the engine
speed before stopping.
Do not tamper with the governor springs, links or other
parts to increase the engine speed. Run the engine at
the speed set by the equipment manufacturer.
Keep the cylinder fins and the governor parts free of
dirt, grass, and debris which can affect engine speed.
Do not transport the engine with fuel in the tank.
Prevent accidental starting by removing the spark plug
wire(s) when servicing the engine or the equipment.
Disconnect the negative wire from the battery terminal
if the engine is equipped with an electric starting
system.
Do not strike the flywheel with a hammer or any
hard object. This may cause the flywheel to shatter
during operation. Use the correct tools to service the
machine.
Do not check for a ignition spark with the spark plug
removed. Use an approved tester.
Do not crank the engine with the spark plug removed.
If the engine is flooded, place the throttle in fast and
crank until the engine starts.
Do not start the engine with the air cleaner and/or the
air cleaner cover removed. Do not operate the engine
without a muffler. Replace the muffler if it is leaking or
worn. Replace only with correct muffler. Do not touch a
hot muffler, cylinder, or fin. It will cause burns.
Do not operate the engine with an accumulation of
grass, leaves, or other combustible material in the
muffler area.
Do not use the engine on any forest covered, brush
covered, or grass covered unimproved land unless
a spark arrester is installed in the muffler. The spark
arrester must be maintained in good working order.
In the State of California, the above is required by
law (Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal
laws apply on federal lands.

Operators Position: The correct position for the
operator is behind the handlebars. Neither the clutch
control handle or the transport wheel lift handle
should be engaged unless the operator is behind the
handlebars.
Engine Controls: The engine controls are all located
on the engine except for the throttle. The engine is
equipped with a On/Off switch, a fuel shutoff valve,
and a choke. Ensure that all engine controls are in
good operating condition. Do not alter engine controls
and/or operate the TurnAer-26 with defective or non-
operational engine controls.
Engine Throttle: The throttle is located on the right
hand side of the handlebar. Pull the
throttle to the left to increase the
engine speed. Set the throttle at
a speed that is comfortable for the operator to walk
safely behind. Decrease throttle speed when operating
in an area with close obstacles.
Transport Wheels Lift Handle: The transport
wheels lift handle, located across the rear of the of
the handlebar, controls the latching mechanism that
enables the transport wheels to be raised or lowered.
Pulling up on the transport wheel lift handle while
pushing down on the handlebar will allow the transport
wheels to be raise while the tines are lowered to the
turf. To remove the tines from the turf and lower the
transport wheels, pull up on the transport wheels lift
handle while pushing down on the handlebars until
the wheel latch mechanism releases. Lift up on the
handlebar until the wheels latch into a fully lowered

Slowly pull back on
the clutch handle to
engage the drive.
The clutch will not act as a brake when released. If the
clutch is released or disengaged when the TurnAer-26
is going up a slope, the machine will freewheel and
roll backwards towards the operator. If the clutch is
released or disengaged when going down a slope, the
machine will freewheel forward.
WARNING
Slowly Engage The Clutch Handle. Fast
Engagement May Cause The Operator to Lose
Control of the Aerator.
Right and Left Turn Steering Brake Control Levers:
Applying the left brake makes the aerator turn left,
applying the right brake makes the aerator turn right.
The brakes slow down one side of the aerator causing
the other side of the aerator to speed up, resulting in
the desired right or left hand turn. Only light pressure
on the brake lever is needed for a turn. Guide the
aerator during the turn with a slight right or left side
pressure on the handlebar to control the turn.
Apply only one steering brake at a time. Applying both
brakes at the same time will cause undue stress on the
steering system. Applying both steering brakes at the
same time will not stop the aerator. To stop the aerator,
release the clutch handle.
DESCRIPTION OF HANDLEBAR IN STORAGE

Plan Your Path - Choose a path with the longest
straight runs to minimize time spent turning at the ends
of rows. For best results, aerate the turf more than once
to maximize the number of holes. Aerate the same
work site at least twice, changing direction of travel by
90° degrees. Change to 45° degrees if aerating for a
third pass. For safety reasons, approach a minor slope
(under 15° slope) moving up and down at a 45° degree
angle to the slope, never operate straight up or down
or across the slope. Never operate the TurnAer-26 on
slopes over 15° degrees.
For maximum time saving, aerate like you mow. Aerate
around the perimeter of the site first, then proceed
along the inside of your original perimeter path.
If the turn at the end of a row or is too tight to use the
steering brakes or if the turn is too close to an obstacle,
turn the aerator by lowering the transport wheels, and
swiveling the machine on the wheels. Then raise the
transport wheels and return to your planned path.
To Start Aerating - Set the engine throttle to
approximately half speed. Move the TurnAer-26 to the
turf before raising the transport wheels to lower the
tines. Raise the transport wheels by pulling up on the
transport wheels lift handle while pushing down on the
handlebar. Continue pushing down on the handlebar
until the transport wheels latch in the raised position.
Slowly pull the clutch back and start aerating. Adjust
the engine throttle speed to a desired walking speed.
To Turn the Aerator - Apply a light pressure on the
appropriate steering brake lever. Apply the left brake to
turn left or the right brake turn right. For best aerating
results, limit turns to gentle sweeping turns and normal
turns at the end of a row. Very tight turns are possible
with the aerator, but the aerating holes will be enlarged
if turns are too tight.
To back-up the TurnAer-26, the transport wheels must
be lowered to remove the tines from the turf. Use the
handlebars to pull the aerator backwards.
To Stop Aerating - To stop, let go of the clutch and
the unit will stop (the engine will continue running).
Lower the transport wheels by pulling up on the
transport wheels lift handle while pushing down on
the handlebar. When the wheels contact the ground,
the latching mechanism will release the wheels. Lift
lightly on the handlebars and the spring assisted
wheel lift will latch the wheels in a lowered position.
During Operation - Stop and check the depth of the
tine penetration by checking the holes with a pen or
pencil. Also, visually inspect the tines often during the
aerating process to ensure that they have not become
plugged with stones or debris. A plugged tine will still
make a hole, but will compact the soil in the hole
instead of removing a core. Compaction of the soil
is the opposite of the effect desired by the aerating
process. When inspecting the penetration depth or
cleaning the tines, Stop the Engine and move to
a level surface. Use caution and wear the proper
protective items when working around the tines.

on the machine. Check under the top guard. Clean
machine before use. Do not high pressure wash.
Storage
TO STORE the TurnAer-26 over a extended period,
clean all surfaces and remove any remaining aeration
cores from the machine. Use only Low Pressure Wash
on the machine. High pressure washing can wash away
the grease from the bearings.
Remove fuel from gas tank and run engine until
carburetor is empty. Prepare engine in accordance with
engine manufacturer’s directions.
To avoid getting a flat spot on the front drums, store with
the front elevated.
Check the tines and remove any cores, stones, or
debris. Apply a light film of light machine oil to the tines
to control rust. See the lubrication directions and follow
the procedures.
If needed, fold the handlebar into the storage position.
Loosen the handlebar locking nuts and rotate the
handlebar forward until locks into a forward position. The
handlebar should not rest on the front bumper. Retighten
locking nuts. Take care not to trap or stress any control
cables.
TO RETURN TO SERVICE AFTER EXTENDED
STORAGE, inspect the entire machine for any damage
that may have occurred during storage. Look for loose
or missing parts. Refer any needed correction to the

TO AVOID SERIOUS INJURY,
Do Not Lubricate Or Adjust The
TurnAer-26 With the Engine Running.
Remove The Wire From The Spark
Plug.
All Of The Following Lubrication And Adjustment
Procedures Involve Or Are Near Rotating Part And
Moving Parts. Follow All Safety Precautions And
Wear The Appropriate Safety Gear.
LUBRICATION
Transport Wheels: Grease fittings on transport wheels
after every 8 hours of operation.
Drive Train Components, Chain, Sprockets, And
Pivot Points: All bearings in the drive train require
no lubrication. Periodic inspection should be done
to insure that any worn bearings are detected and
replaced. The chains requires no lubrication. Protect
chains from rust and moisture with a very light coating
of machine oil. The chain sprockets should be cleaned
of any dirt build-up to ensure proper chain contact.
Periodically inspect the chain and sprockets for wear
or damage. Replace if necessary. Periodically clean
the entire machine of dirt, grease and grass build-up
and lubricate all pivot points with light machine oil.
Engine and Gear Reducer: CHECK OIL LEVELS
DAILY. Follow the engine manufacturer’s manual for
intervals of oil change, proper oil types, and fill levels
for the engine and the gear reduction unit.
ADJUSTMENTS
Check and retighten nuts and screws frequently to
ensure safe operation.
Chain Idler Sprocket Adjustment (See Figure 6):
The chain idler sprockets (one located under each side
chain guard) can be adjusted to remove excess slack
in the drive chains caused by chain wear or stretch.
Remove side guards. Before adjusting idler sprocket
position, ensure that the chain and all sprockets have
been cleaned and that the chain seats properly on
the sprockets. A build-up of dirt on the sprockets or
chain can cause the chain to become too tight. Inspect
all the sprockets, bearings, and the chain for wear or
damage.
Step 1. Remove both side guards and elevate tine reels.
Step 2. Loosen the idler sprockets. Move idler
sprockets along adjusting slot until the chain has an

up and down movement of 1/2” inch to 3/4” inch. Take
measurement at a center point on the chain between
the front drum sprocket and the tine reel sprocket.
Ensure that all slack in the chain is taken up between
the other sprockets before taking measurement.
Step 3. Retighten idler sprocket and recheck tension
setting measurement. Replace both side guards.
Clutch Cable and V-Belt Adjustment (See Figure
6 and Figure 7): The clutch cable has an adjuster
(located near the spring on the cable) to increase or
decrease the V-belt tension. If the V-belt is slipping
when the clutch handle is fully engaged, the V-belt
tension needs to be increased. If the clutch engages
rapidly or “grabs” when the clutch handle is slightly
engaged, the V-belt tension needs to be decreased.
Also, decrease the V-belt tension if the machine
“creeps” forward when the clutch is not engaged.
Before adjusting, inspect the V-belt, clutch cable, and
the clutch cable spring for damage and wear. Replace
spring or V-belt if proper operation cannot be reached
with cable adjustment.
NOTE: Check the engine mounting hardware. If the
engine has moved during operation, it will affect the
adjustment and operation of the clutch. The engine
should be fully back (towards operator) in the slots in
the frame where the engine is mounted.
Step 1. Refer to Assembly instructions in the front of
this manual (Figures 2 and 3 on Pages 6 and 7).
Ensure that the upper end of the clutch cable is
mounted to the proper hole in the clutch control
handle. Mounting holes correspond to the mounting
height of the handlebar.
SERVICE
Step 2. Loosen the lock nut on the cable adjuster.
Change the tension cable by turning the adjuster.
Limit adjustments to one turn at a time until tension
is correct. Shortening cable increases tension.
Step 3. Proper adjustment range is measured on the
spring at the cable end. The spring should stretch
1/2” to 3/4” (13 mm to 19 mm) from its original length
when the clutch handle is engaged.
Step 4. Test and repeat adjustment as required.
Step 5. If proper adjustment can not be reached within
the range of the adjuster, move the upper cable
mounting point to the next higher hole on the clutch
handle. Repeat the adjusting steps as needed.
NOTE: If the handlebar is mounted in the highest
position, the cable can be moved to the other side of
the clutch handle for added cable tension.
Step 6. If proper tension can not be reached with the
earlier steps, change the location of the engine.
Use the following procedure to properly adjust the
location of the engine:
● Loosen the four bolts that hold the engine to the frame.
Slide engine forward (away from handlebars).
● Verify that the engine is aligned straight and retighten
the bolts securely.
● Move belt stop bracket forward the same distance as
the engine moved forward (if needed).
● Repeat the clutch cable adjustment procedures (after
moving the engine).
● Recheck the adjustment to the belt stop bracket. The belt
should touch the tips of the belt stop when the clutch is
not engaged but not touch when the clutch is engaged.

Steering Brakes Cable Adjustment (See Figure 8):
The brake cable conduit end has an adjustment to
take-up any slack in the cable caused by cable stretch.
Cable adjustment is also required if the brake assembly
has been removed for service. After adjustment, check
brake operation to ensure that the brakes will steer the
machine. Both right and left hand brake should require
the same amount of pressure at the steering brake
control levers to control steering. See Steering Brake
Pad Adjustment for further brake adjustment.
Step 1. Remove the top guard from the aerator.
Step 2. At the brake cable conduit end, loosen the
inside jam nut. Turn the outside jam nut until proper
adjustment is reached. Ensure that the brake pads
do not rub on the brake rotor when the steering
brake levers ARE NOT applied. Ensure that the
brake levers completely return when released.
Step 3. Tighten the inside jam nut to lock the adjustment
and to secure the cable conduit end. Replace the
top guard.
Steering Brake Pad Adjustment (See Figure 9): The
brakes have a pad adjusting screw to allow adjustment
for wear in the brake pads and the brake rotor. Before
adjusting, ensure that the steering brake levers are
not depressed, damaged, and do not bind or stick
when operated. Check that the steering brake housing
(caliper) is free to slide back and forth on the upper and
lower brake mounting brackets. Adjust both the right
and left hand brakes to ensure equal and even steering
control. After adjustment, check brake operation to
ensure that the brakes will steer the machine. Follow
Steering Brake Cable Adjustment procedures if cable
needs to be readjusted. Replace pads, brake assembly
or rotor if worn beyond adjustment.
Step 1. Unlock the jam nut for the pad adjusting screw.
Turn the pad adjusting screw until the pads very
lightly touch the rotor.
Step 2. Slightly back off the pad adjusting screw until
the pads not longer touch the rotor. Turn the rotor and
check that the pads do not contact the rotor. Some
pad and rotor contact is normal as the brake housing
“floats” on the brake mounting brackets and rotor will
have some side play, however the pad contact should
be very light and minimal.
Step 3. Tighten jam nut to secure adjusting screw.
Step 4. Steering brake levers and cables must operate
freely without excessive force. Replace top guard.
Wheel Lift Spring Tension Adjustment (See Figure
10): The lift springs are meant to assist in the lifting of
the aerator. The operator should only need to apply a
light lifting force on the handlebars to raise the machine.
If excess lifting force is required or the wheels do not
latch on there own, spring adjustment is required. When
lowering the aerator, only a light downward force on the
handlebars should be needed.
Step 1. Clean & lightly lubricate latching mechanism.
Step 2. Locate spring adjusters. Check the measurement
on the adjusters (See figure 10). Both adjusters
should be set at equally 2-3/4”.
Step 3. If needed, increase lifting force by tightening
adjusters. Tighten both adjusters equally.
Step 4. Test and readjust as needed. If springs fails to
lift, replace springs.

Use the following steps for V-belt replacement:
Step 1. Disconnect the clutch cable at the clutch control
handle. Do not change the cable adjuster setting.
Step 2. Remove the top guard.
Step 3. Locate the shaft coupling [A] and disassemble.
Before disassembly, note the location of the
identifying punch mark [B] on the top half of the
coupling and the matching “X” marks [C] on the
upper and lower halves.
Step 4. Remove the square key [D] from the shafts.
Step 5. Remove and install the old and new V-Belt thru
the space between the shafts [E].
Step 6. Reinstall the key [D].
Step 7. Reinstall shaft connector [A]. Punch mark [B]
must be towards the large pulley, the “X” marks
must both be on the same side of the connector.
The edge of the connector block should be 3/16” to
1/4” inch (4.8 mm to 6.3 mm) away from the edge
of the differential housing. Note: If installing a new
connector, discard shims between the connector
halves.
Step 8. Tighten bolts evenly in an “X” pattern (See
Detail A For bolt tightening sequence). Torque to 23
Ft-Lbs. (276 In-Lbs or 31.1 NM).
Step 9. Replace the top guard.
Step 10. Reinstall the clutch cable to the clutch control
handle.
Step 11. Test and readjust the clutch cable as needed.
