5.6 TO DRIVE / TRANSPORT ____________________________________________________
Read and follow all safety notes contained in this manual
when driving or transporting aerator. Refer to Section 5.2
for general operating instructions. When operating in
reverse look behind you to ensure you have a clear path.
Important: If this aerator is driven on public roads, it
must comply with federal, state and local ordinances.
Contact local authorities for regulations and equipment
requirements.
1. Disengage all drives and raise aerator heads to the
transport position when driving to and from the area
of operation.
2. Disengage parking brake and move throttle lever to
“Fast”. Depress traction pedal slowly.
5.7 AERATING _______________________________________________________________
Drive unit to location to be aerated. To prevent turf
damage, advance throttle to wide open position and start
at slow forward speed before lowering the aerator frame.
When aerator is fully down, the foot speed control should
be pressed firmly against the speed control stop to
maintain constant spacing. After a short run, check hole
spacing to calibrated handle. Adjust as required to be
sure calibrated handle is same as actual hole spacing.
Unit may be turned while aerating. Hole spacing will vary
during turning radius. After eight (8) hours of use, check
roller chains for proper tension. Adjust as required.
.
5.8 HILLSIDE OPERATION _____________________________________________________
The aerator has been designed for good traction and
stability under normal aerating conditions; however, use
caution when operating on slopes, especially over rough
terrain or when the grass is wet. Wet grass reduces
traction and steering control.
1. Always aerate with the engine at full throttle but
reduce forward speed to maintain the proper aerating
frequency.
2. If the aerator tends to slide or the tires begin to
“mark” the turf, angle aerator into a less steep grade
until traction is regained or tire marking stops.
3. If aerator continues to slide or mark the turf, the
grade is too steep for safe operation. Do not make
another attempt to climb, back down slowly.
4. Correct tire pressure is essential for maximum
traction
CAUTION
To prevent tipping or loss of control, travel at reduced
speed when making turns.
!
WARNING
DO NOT leave the seat UNLESS the aeration head is
RAISED and the direction/speed control pedal is in
the NEUTRAL position or the engine will stop. This
may result in personal injury and/or turf damage.
!
WARNING
To minimize the possibility of overturning, the safest
method for operating on hills and terraces is to travel
up and down the face of the slope (vertically), not
across the face (horizontally). Avoid unnecessary
turns, travel at reduced speeds, stay alert for hidden
hazards, and drop offs.
CAUTION
Do not operate this aerator on slopes greater than
13°.
!
!
WARNING
To prevent serious injuries, keep hands, feet and
clothing away from aerating unit when the tines are
moving.
NEVER use your hands to clean aerating units. Use a
brush to remove grass clippings from tines. Tines can
be sharp and could cause injuries.
To clear obstructions from aerating unit, raise aerator
heads, engage parking brake, stop engine and
remove key from ignition switch then remove
obstruction.
!

2. Grease and lubricate all points if required. To
prevent fires, wash the aerating units and aerator
after each use.
a. Use only fresh water for cleaning your
equipment.
Note: Use of salt water or affluent water has been
known to encourage rust and corrosion of metal parts
resulting in premature deterioration or failure. Damage
of this nature is not covered by the factory warranty.
b. Do not use high pressure spray.
c. Do not spray water directly at the instrument
panel, or any electrical components.
d. Do not spray water into the cooling air intake or
the engine air intake.
Note: Do not wash a hot or running engine. Use
compressed air to clean the engine and radiator fins.
3. Fill aerator’s fuel tank at the end of each operating
day to within 1 in., (25 mm) below the filler neck.
Use clean, fresh, unleaded gasoline, 87 octane
minimum.
4. Handle fuel with care - it is highly flammable. Use
an approved container, the spout must fit inside the
fuel filler neck. Avoid using cans and funnels to
transfer fuel.
5. Store fuel according to local, state or federal
ordinances and recommendations from your fuel
supplier.
WARNING
To prevent injury, use brakes in FREE WHEEL mode
on slopes and ramps.

6. Inspect hydraulic hoses and tubes daily. Look for
wet hoses or oil spots and replace worn or
damaged hoses and tubes before operating the
machine.
7. Check the engine oil and hydraulic oil at the start of
each day, before starting the engine. If the oil level
is low, remove the oil filler cap and add oil as
required. Do not overfill.
WARNING
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use
paper or cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected
into the skin, it must be surgically removed within a
few hours by a doctor familiar with this form of injury
or gangrene may result.
