TIRES
Maximum tire pressure under any circumstances is 30
p.s.i. Equal tire pressure should be maintained on all
tires. Check tire sidewalls for proper inflation.
When installing a tire to the rim, be certain rim is clean
and free of rust. Lubricate both the tire and rim
generously. Never inflate to over 30 p.s.i. to seat beads.
WARNING: Excessive pressure (over 30
p.s.i.) when seating beads may cause tire/
rim assembly to burst with force sufficient
to cause serious injury.
FUEL FILTER
Your unit is equipped with a replaceable in-line fuel
filter. Replace filter whenever contamination or
discoloration is noticed. Order replacement filter
