Battery  gives  off  flammable  fum es  that  can 

explode.

When  starting  from  another  machine,  make  sure 

the  machines do  not touch.

This will  prevent damage to  engine  bearings and 

electrical  circuits.

Always  connect  the  battery 

POSITIVE

battery 

POSITIVE 

(+) 

and 

the 

battery 

NEGATIVE 

(-) to  battery 

NEGATIVE (-).

Jump  only  with  a  battery  source  and  with  the 

same  voltage  as  the  stalled  machine.  This 

machine  has  a 

12 

volt  starting  system.  Use  only 

equal  voltage  for  lump  starting.  Use  higher 

voltage will  damage the electrical  system.

Be  sure  the  start  switch  is  in  the 

OFF 

position 

BEFORE 

attaching  the  jum per  cables  to  the 

machine to  be  started.

Use of Jumper Cables

1. 

Move  boost  start  machine  near  enough  to 

stalled  machine  for  the jum per  cables  to  reach. 

But,  do  not  allow machines to touch.

2. 

Lower the  bucket to the ground.

Move  all  controls  to 

HOLD. 

Stop  the  engine  on 

boost machine.

4.  Connect 

POSITIVE 

(+)  jum per  cable  (red) 

POSITIVE 

(+)  cable  terminal  of  discharged 

battery.

Do  not  allow  positive  (+)  cable  clamp  to  touch 

any  metal  other than  battery terminals.

5.  Connect 

POSITIVE 

(+)  jum per  cable  (red) 

POSITIVE 

(+)  cable terminal  of boost battery.

6

.  Connect  one  end  of 

NEGATIVE 

(-)  jum per 

cable  (black) to the

NEGATIVE 

(-)  boost battery terminal.

7.  Make final  connection  of 

NEGATIVE 

(-)  cable to 

frame  of the  stapled  machine  (not 

NEGATIVE 

(-) 

post)  away from  battery or fuel  line.

8

.  Start the  engine on  the  boost machine.

9.  W ait a  minimum  of two  minutes  for the  batteries 

in  the stalled  machine to  partially charge.

10.  Attempt to start the stalled  engine.

Refer to  section  on  Engine  Starting.

11.  Immediately 

after 

starting 

the 

engine, 

disconnect the jum per cables  in  reverse order.

12.  Conclude  failure  analysis  on  starting/charging 

system  of  stalled  machine  as  required  now  that 

engine  is  running  and  charging  system  is  in 

operation.

3. 

On  stalled  machine,  turn  the  start  switch  key  to
