REMOVING / INSTALLING / JUMP STARTING

WARNING: 

When removing or

installing the battery, follow these
instructions to prevent the screwdriver
from shorting against the frame.

Removing the Battery: Disconnect negative cable
first, then positive cable.
Installing the Battery: Connect positive cable first,
then negative cable.
Jump Starting

1.

First, connect end of one jumper cable to the
positive terminal of the good battery, then the
other end to the positive terminal of the dead
battery.

2.

Connect the other jumper cable to the negative
terminal of the good battery, then to the FRAME
OF THE UNIT WITH THE DEAD BATTERY.

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: 

 

Figures 25, 29 and 30 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
securely.

2.

Disconnect the spring which is attached to a
bracket on the transaxle, inside the right rear
wheel. Use a spring puller or other suitable tool.

NOTE: 

When reassembling, make certain belt

keeper pins are assembled in the same locations
from which they were removed. See Figure 25.
