1.2 Checking the Batteries 

 

Sound  battery  condition  is  critical  for  good 
engine  performance  and  safe  operation  of  the 
machine. 

Improper 

electrolyte 

levels 

(if 

applicable)  or  damaged  cables  or  wires  may 
cause damage to engine components and bring 
hazardous conditions. 

!

Note: Checking electrolyte level is 

not  required  for  machines  with  sealed 

or maintenance-free batteries. 

!

Warning: danger of electric shock.   

Contact  with  an  electrical  circuit  may 
result  in  death  or  serious  personal 
injury.  Take  off  all  rings,  watches  and 
other jewelry. 

!

Warning: danger of bodily injury.   

The battery contains acidic substances. 
Avoid overflow of the acidic substance 
or  contact  with  it  in  the  battery.  Use 
soda  and  water  to  neutralize  any 
overflowed acid. 

1) 

Wear  protective  clothing  and  protective 
glasses. 

2) 

Make  sure  the  battery  cables  are  firmly 
secured and not corroded. 

3) 

Make sure the battery hold-down bracket is 
secure. 

!

Note:  Adding  a  terminal  protector 

and an anti-corrosion sealant will help 
prevent corrosion on battery terminals 
and cables. 

1.3Maintenance of 

worm-Type Slewing Drive 

There are three positions to be lubricated on the 
worm-type 

slewing 

drive 

assembly, 

i.e., 

lubrication  of  the  roller  path  (Position  I), 
lubrication of the engaging position (Position II) 
between the worm and the slewing bearing, and 
lubrication of the tapered roller bearing (Position 
III). The specific lubrication positions are shown
