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 muer
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.
