MAINTENANCE AND SERVICE

Functional inspection

General

Functional inspections must ensure that the machine’s functions are intact.

Brake functions

•Check the drive brake’s function by operating the machine on a slope. Release the joysticks. The ma- chine should then be braked and remain stationary.

•Check the slew brake’s function by rotating the arm on a slope. Release the joysticks. The arm should then be braked and stop gently.

Cooler

Overheating has a negative effect on the service life of the machine’s components. Clean the cooler when necessary. Refer to “Cleaning the machine” in the “Maintenance and service” section.

Cylinders

Checking cylinder tubes and piston rods must be done with the cylinders extended to the end position. Replace damaged components immediately.

•Check that the cylinder tubes are not dented or cracked.

•Check that the piston rods are undamaged and straight. A damaged piston rod causes contamina- tion in the hydraulic system, resulting in mechani- cal damage.

Tool attachment

Warning!

The tool attachment’s cotter and pin are impor- tant safety components. A worn or damaged cotter must be replaced with an original spare part, manufacturing your own cotters is not permitted.

•Check that the tool attachment is complete and that all parts are intact and correctly mounted.

Automatic track tensioning

The caterpillar tracks are tensioned automatically when the outriggers are up.

Should demolition material or suchlike enter into the side of the tracks during operation, their spring func- tion should prevent breakdowns and stoppages. The spring function consists of a hydraulic accumulator.

Checking track tension

•The track must not slacken by more than 10-15 mm. Operate the outriggers up and then down. Wait 15 minutes and then check.

•If the tracks become slack it can be due to one of the track tensioning function’s non-return valves being blocked or broken.

Cleaning non-return valves

The non-return valves can be cleaned by discharging the pressure in the accumulator and thus loosening the tension of the tracks.

•Pull out the valve and rotate it a quarter turn to lock it in open position.

•Operate the outriggers up and down. Hydraulic ßuid is then pumped around and cleans the non- return valve.

•Rotate and release the valve back into position. Operate the outriggers up and down to tension the track.

Hammer lubrication

Check that grease is reaching the hammer by dis- mantling the grease hose at the hammer. Start the machine and activate the hammer function. Exercise great caution during the inspection to ensure that nobody is injured.

Tools

Check that the tool can be used in such a way that neither the operator nor people in the vicinity are exposed to unnecessary risks. Refer to the supplier’s Operator’s Manual for other checks.
