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.
