Section 4 Troubes hooting 4.3 Troubeshooting the Push/Pu Circuit There are six potentia probems that coud affect push/pu operation. InsuffIcient hydrauic pressure Externa eaks Defective soenoid (on soenoid-equipped attachments) Worn or defective cyinder seas Vave assemby mafunction Kinked suppy hoses Before proceeding with a test, determine whether the push function, pu function, or the gripper function is at faut. Then foow the check ist under the probem function (paragraph 4.3-1, 4.3-2, or 4.3-3) to isoate the probem area. In a cases, make sure the truck is deivering sufficient hydrauic pressure. A pressure drop of no more than 100 psi beow the truck reief vave setting at the auxiiary vave port is OK. If the pressure is not as specified, refer to the truck service manua for adjustment or service procedures. Pressure must not exceed 2000 psi. 4.3-1 Push Function Pressure Test 1. At the attachment vave assemby, disconnect the suppy hose that eads to the base end of the right-hand push/pu cyinder (as viewed from the driver s seat). Pug the cyinder suppy hose with a No. 6 meta pug. 2. Connect a pressure gauge with a neede shutoff vave and drain ine to the vave fitting (refer to paragraph 4.1-2 for an iustration of the gauge arrangement). Put the drain ine in an empty container. 3. Open the neede vave no more than ½ to 1 fu turn. Start the truck and et it ide. 4. Operate the truck push ever for 4 to 5 seconds, then cose the neede vave tighty. Aow the gauge to reach and hod fu truck reief pressure for 2 or 3 seconds, then reease the push ever.
