OUTLINE OF SERVICE
GREASE
Grease is used to prevent seizure and noises at the joints.
This construction equipment is used under heavy-duty conditions. Always use the recommended grease and
follow the change intervals and recommended ambient temperatures given in this Operation and Maintenance
Manual.
The nipples not included in the maintenance section are nipples for overhaul, so they do not need grease.
If any part becomes stiff after being used for long time, add grease.
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.
