Product maintenance

This used track excavator is definitely a complex machines. But maintaining them doesn’t

have to be. Follow these suggestions in your Operation and Maintenance Manual, stick to a

routine maintenance schedule and perform a thorough walkaround inspection on

used excavators.

1. 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.

2. 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.

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. 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.
