4.3 PULVERIZER MOUNTING PROCEDURE

1. Place the pulverizer on the ground(or wood block) with blocking to keep the

pulverizer level for installation.

2. Remove the bucket or other attachment following the manufacturer’ s recommended procedure.Be careful not to contaminate the hydraulic system by plugging the hydraulic hoses.

3.

With the jaws of the crusher facing the excavator, operate the excavator into proper

position, lining the excavator’ s arm(second boom) into the top bracket pivot of the pulverizer.

4.

Pin the excavator’ s arm and crusher top bracket pivot together.

5. Pick the pulverizer up into a proper position where the second linkage pin can beinserted. Insert pin.

5.

Connect the hydraulic hoses to the manifolds(or fitting) located on each side of the top. Tighten the bolts or cap to the proper torque.

When installation is complete, fully extend excavator bucket cylinder to curlcrusher. Check for interference. Contact factory or authorized dealer if any

interference occurs.

7.

Lift the boom and slowly try the pulverizer open and close function. Watch for

hydraulic oil leakage.

Observe flow rate and pressure range or the warranty will become void.



14

4.4 PULVERIZER REMOVAL PROCEDURE

1. Position the pulverizer under the boom of the excavator.

Trapped hydraulic pressure may be present after base machine is turned off.

Extreme caution must be taken when removing crusher hydraulic hoses or possibleinjury or death could result.

2.

Disconnect the hydraulic hoses. Be careful not to contaminate the hydraulic system by plugging the hydraulic hoses.

3.

Remove the bucket cylinder pin from the pulverizer mounting bracket.

4.

Remove the arm pin of the excavator from the pulverizer mounting bracket.
