Grease
 Grease is used to prevent wear and noise at the joints.
 This construction machine is used under heavy-duty condi-
tions. Always use the recommended grease and follow the
change intervals and ambient temperature recommendations
given in this Operation and Maintenance Manual.
 The nipples not included in the maintenance section are only
used in repairs and do not need to be greased.
When using the machine after it has been in storage for a long
time, carry out greasing if there is any stiffness or screeching.
 Always wipe off all of the old grease that is pushed out when
greasing.
Be particularly careful to wipe off the old grease in places
where sand or dirt sticking in the grease would cause wear of
the rotating parts.
Storing oil and fuel
 Keep indoors to prevent contamination with water, dirt, or
other foreign materials.
 When storing drum cans for a long period, put the drum on its
side so that the filler port of the drum can is at the side to pre-
vent moisture from being sucked in.
If drum cans have to be stored outdoors, cover them with a
waterproof sheet or take other protective measures.
 To prevent deterioration of the quality during storage, be sure
to use fuels and lubricants in the order of first in – first out (use
the oldest oil or fuel first).
