WARNING: Failure to use this
procedure could cause sparking, and the
gas in either battery could explode.
CLEAN THE BATTERY
Clean the battery by removing it from the unit and
washing with a baking soda and water solution. If
necessary, scrape the battery terminals with a wire
brush to remove deposits. Coat terminals and
exposed wiring with grease or petroleum jelly to
prevent corrosion.
BATTERY FAILURES
Some common causes for battery failure are:
incorrect initial activation, lack of water, adding
chemicals other than water after initial activation,
undercharging, overcharging, corroded connections,
freezing. These failures do not constitute
warranty.
TIRES
Recommended operating tire pressure is
approximately 10 p.s.i. Maximum tire pressure
under any circumstances is 30 p.s.i. Equal tire
pressure should be maintained on all 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 REMOVAL AND REPLACEMENT
WARNING: Disconnect the spark plug
wire(s) and ground it against the engine.
Block the wheels of the unit.
NOTE:
Figure 25 and 27 are shown with the unit
tipped up for clarity. It is not necessary to tip the unit
to remove the belts.
However, if tipping the unit is desired, remove the
battery from the unit. To prevent gasoline leakage,
drain the gasoline, or remove the fuel tank cap,
place
a thin piece of plastic over the neck of the fuel
tank and screw on the cap. Be certain to remove the
plastic when finished changing the belts. Block unit
