TROUBLESHOOTING

IF THE BATTERY GOES DEAD

Disconnecting the jumper cables

Once the dead machine is successfully

running, remove the jumper cables by

following the same steps as for connection in

the reverse order.

1. Disconnect the clip of jumper cable (B)

from the engine block of the dead

machine.

2. Disconnect the other clip of jumper cable

(B) from the negative (-) battery terminal of

the booster vehicle.

3. Disconnect the clip of jumper cable (R)

from the positive (+) battery terminal of the

booster vehicle.

4. Disconnect the clip of jumper cable (R)

from the positive (+) battery terminal of the

dead machine.

Recharging

Ask your sales or service dealer for

recharging the dead battery.

TROUBLESHOOTING

IF A FUSE BLOWS

INSPECTING THE FUSIBLE LINK

If the machine is not turned on after turning

the starter switch to the ON position, there is

likely a break in the cartridge type fusible link

(1).

1. Open the right side cover.

2. Loosen the bolts and remove the cover

(2).

3. Inspect the fusible link (1).

4. If there is a break, please contact your

sales or service dealer.

Note: Fusible links are large type fuses used

in high current applications. Like a regular

fuse, they act as fuses by protecting the

electric components and wirings from

damage caused by excessive current draw.

FUEL

BLEEDING AIR FROM THE FUEL SYSTEM

IMPORTANT: NEVER use the starter

motor to crank the engine in order to

prime the fuel system. This may cause the

starter motor to overheat and damage the

coils, pinion gear and/or ring gear.

IMPORTANT: If the engine stalls due to

fuel shortage, add fuel, turn the key to the

ON position for 60 seconds, and then turn

it to the START position. Running the

starter for a long time before there is

enough fuel is going through can cause

the starter to fail.

1. Add fuel.

2. Turn the starter key to the ON position and

hold it for about 60 seconds.

The automatic air bleeder bleeds air from

the fuel system.

Note: Air in the fuel system causes the

engine to fail to start or to have other
