Track Maintenance And Adjustment
Check the tracks daily because the stability of the
compact excavator can be dramatically affected by
damage to tracks.
Check for:
— Damage or wear
— Correct tension according to manufacturer’s
instructions
— Proper lubrication of track rollers and idlers—refer to
the manufacturer’s manuals.
Track tension is important for good performance,
reducing excessive track wear and preventing the tracks
from coming off. Track and roller wear varies with
working conditions and soil conditions. Special tools
and procedures may be needed to check or adjust track
tension. Follow manufacturer’s specific service
procedure(s) when removing and installing tracks.
WARNING! Track tensioning systems have compressed
springs or pressurized fluid (oil or grease). Improperly
releasing track tension forces can result in death or
serious injury.
Always follow the manufacturer’s
warnings and instructions for track adjustment and
other maintenance and servicing procedures.
WARNING! Avoid possible death or serious injury.
Never strike or pound on track tension springs.
They may be under very high compression and could
shatter explosively.
