LUBRICATION

Low viscosity grease is applied to this rotary hammer so that it can be used for a
long period without replacing the grease. Please contact the nearest service agent
for grease replacement when any grease is leaking from loosened screw. Further
use of the rotary hammer despite the grease shortage causes seizure to reduce the
service life.
CAUTION: A specific grease is used with this machine, therefore, the normal
performance of the machine may be badly affected by use of other
grease. Please be sure to let one of our service agents undertake
replacement of the grease.
