Product maintenance
Such a complex used excavator is definitely a complex machines. But maintaining them doesn’t
have to be. Follow the steps in your Operation and Maintenance Manual, stick to a routine
maintenance schedule and perform a thorough walkaround inspection on used excavators.
1. Tracks
Make sure your used hydraulic excavator’s tracks are set at the proper tension. They’ll wear
more quickly if they’re too tight or too loose. Chains and sprockets can also wear prematurely
if tracks aren’t maintained correctly. As you examine the tracks, keep an eye out for any wear
to the common track components - track shoes, pins, chains, idlers, sprockets and fasteners.
2. Undercarriage
The undercarriage problems of the used crawler excavator can account for more than half of
your maintenance costs. It’s not just the most expensive part of your excavator — it’s also
exposed to near-constant wear and stress. Clean out any dirt and debris collected during a
shift to help prevent buildup that could accelerate wear. (It can also hurt fuel economy by
adding extra weight.) And perform a thorough inspection every shift to look for missing or
damaged components or uneven or excess wear.
3. Filters
Filters keep your excavator’s engine, air, fuel and hydraulic systems running smoothly. Most
used track excavators come with an indicator that lets you know when filters need attention.
Act quickly when alerted to change filters to avoid the contamination that can lead to costly
damage and downtime.
4. Water separator
If you leave your excavator outside overnight, condensation can cause water to build up in
the primary fuel filters. Used excavators come with water separators on these filters, and a
sensor inside the cab tells you when water has collected there. Drain it when indicated or it
can lead to corrosion and damage.
5. Cooling system
Adequate airflow and coolant levels allow your used excavator excavator to run efficiently.
Both are especially important if you work in a very hot climate — you don’t want your machine
to overwork just to keep cool. Be sure to inspect coolant hoses for leaks. Also, apply low-pressure
water or air to clean the oil cooler, condenser and radiator. Reversing fans are a key feature
on these second hand excavators to help maintain a clean radiator.
6. Daily inspection
Your used excavator’s work tools do the work — so don’t overlook them in your daily inspection.
Check any attachments, including couplers, for cracks, excessive wear or signs of damage
that could hamper your productivity and safety. Using a bucket? Inspect it for cracks, bowing,
pin and bushing wear. Look for abnormal wear to the adapters, teeth, cutting edges, and side
cutters. And make sure all work tools are securely attached to the machine for safety.
