GrassFlap Cable Installation
WARNING: PROPER CABLE INSTALLATION AND MAINTENANCE
IS CRITICAL TO LIFE OF CABLE
4) AREAS TO PAY PARTICULAR ATTENTION TO ARE:
1. Do not bend cable wire.
2. Make certain the cable is not in a bind when the deck is raised either manually
or when mowing.
3. Leave enough slack where the cable is tied to mower to keep out of the belts
for the deck to raise and lower without straining the cable.
4. Avoid direct heat on cable, do not route near muer
5. Maintain recommended bend radius of 6 inches for all bends.
3) MAINTAINING THE CABLE:
1. Be sure the rubber boot is in place to keep dirt and water out of cable.
2) PROPER PEDAL HEIGHT:
1. Adjust pedal height so pedal bottoms out with full pressure to
prevent cable from carrying full weight of operator. Start with
cable tting as shown - adjust pedal end to raise pedal, adjust
ap end to lower pedal. Verify pedal height with ap in
balance (half open) position.
DO NOT BEND
1) Improper cable routing WILL cause failure, usually within
the rst month of use. The rst 1/2 inch of cable conduit
(black exible part) must be straight in line with the end tting.
Cable wire near ball must not be bent during installation.

Safety and Warnings
Thrown objects
Mowing with power equipment involves certain risk including but not limited to thrown objects. Be sure to clean up
the area to be mowed and remove objects that could be thrown by the blades BEFORE you start mowing
Once the grass flap is installed your mower will be equipped with an operator controlled discharge chute (OCDC).
Do not operate the mower if the OCDC is not properly attached. This discharge chute has a variable adjustment
from fully open to fully closed. In the closed position it will serve to keep some of the clipping material under the
mower deck for a longer period of time, in order to enhance the mulching capabilities, as well as function as a
safety shield. The discharge chute should ALWAYS BE IN THE CLOSED POSITION WHEN MOWING WHILE
PEOPLE ARE PRESENT IN THE IMMEDIATE VINCINITY.
Do not allow anyone in the area while mowing. If someone does enter the area, stop mowing immediately until they
leave.
Moving parts
The mower deck has spinning mower blades that can amputate hands and feet. Do not allow anyone near the
mower while it is running! Keep safety devices (guards, shields, and switches) in place and working.
Children
Tragic accidents can occur with children. Do not allow then anywhere near the area of operation. Children are
often attracted to the unit and mowing activity. Never assume that children will remain where you last sat them. If
there is a risk that children may enter the area where you are mowing, have another responsible adult watch them.
General Safety Precautions
1.
Do not mow when children, pets, or others are present. The operator is responsible for the safety of others
within the vicinity of the operation of your mower.
2.
Keep hands, feet, and clothing away from rotating blades or other rotating parts while the engine is
running.
3.
Do not attempt to open or close the flap at the discharge chute while the engine is running, doing so
could result in personal injury including loss of hands, feet or death.
4.
Clear work area of objects (wire, rocks, and debris of any kind) that can be picked up and thrown by the
mower, and possibly damage the equipment or cause personal injury to the operator.
5.
Do not attempt to adjust or repair the mower deck, grass flap, or related components while the engine is
running. You must disengage power to attachments, disengage PTO, set parking brake, set steering
controls to neutral, shut off the engine, and remove the key before making any repairs or adjustments or
attempting any of the following tasks:
a.
Flap connecting linkage adjustment
b.
Flap removal or cleaning
c.
Unclogging the chute
Failure to comply can result in personal injury, loss of limb, or death.
6.
Keep all nuts, bolts, screws, and other fasteners in place and properly secured to be sure
equipment is in safe working condition.
7.
Keep equipment and attachments in good operating condition and keep safety devices, such as guards,
shields and covers in place and working.
8.
Do not operate the mower or attachments if any guards are missing or not functioning.
9.
Stop the mower and attachments, secure the mower, and inspect for damage after striking a foreign
object. Repair any damage before restarting and operating the equipment.
10.
Use personal protective equipment when operating mower of performing maintenance, such as (but not
limited to) protection for eyes, feet, and head. Do not operate or service the mower when barefoot or
wearing open-toed sandals.
11.
Obey all safety decals.
