TIRES
Recommended operating tire pressure is
approximately 14 p.s.i. on 14 inch tires and 20 p.s.i.
on 16 inch tires. (Check sidewall of tire for tire
manufacturer’s recommended pressure). Maximum
tire pressure under any circumstances is 30 p.s.i.
Equal tire pressure should be maintained on both
tires.
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.
BELT REPLACEMENT
CAUTION: Do not use an off-the-shelf
belt.
Your tiller has been engineered with a belt made of
special material (Kevlar Tensile) for longer life and
better performance. It should not be replaced with
an off-the-shelf belt.
If belt replacement is required, order belt or belts by
part number from your nearest authorized dealer.
