OPERATION
PREOPERATION PROCEDURES
DAILY MAINTENANCE CHECKS
Check for loose or missing fasteners. Tighten or replace as needed. See Torque Specifications in the ASSEMBLY section of this manual.
Check to be certain that the flow control valve on the car- rier is set to the proper flow for the compactor. See the SPECIFICATIONS section of this manual.
Check shock mounts for cracks or tears. Rotate shock mounts 180° when fatigue tears begin to show at top outer crease of the shock mount. This will prolong the life of the shock mount.
Check for abrasion and hydraulic leaks at fittings and hos- es. Replace defective hoses and fittings. Adjust hoses and tighten fittings so the hoses do not deflect into contact with structure during use.
WARNING
DO NOT USE BARE HANDS TO CHECK OR SEARCH FOR HYDRAULIC LEAKS AROUND HOSES AND FIT- TINGS. PINHOLE LEAKS CAN PENETRATE THE SKIN. TO INSPECT FOR LEAKS, DEPRESSURIZE THE SYS- TEM, CLEAN AROUND SUSPECTED AREA, REPRES- SURIZE THE SYSTEM, AND VISUALLY CHECK FOR LEAKS.
Lubricate bearings with two pumps of grease every 40 hours of operation. A greasing location is provided in both bearing carriers.
Inspect pins and bushings for correct fit and lubrication.
Check level of hydraulic reservoir on carrier.
Make certain that quick couplers are fully engaged and leak free.
PRE-INSTALLATION INSTRUCTIONS
Test the carrier hydraulic system to verify that the system is operating at the manufacturer's specified capacity and pressure ratings.
Be sure the fluid and filter in the hydraulic system are clean.
When tightening pipe threads, be careful that any seal-
ant used (Teflon ® tape, etc.) does not enter the hydraulic system. Foreign matter introduced into the system may damage hydraulic valves, motors and pumps.
Follow instructions to install the Stanley priority valve in the carrier hydraulic system. the warranty is in effect only if the valve and compactor are installed as outlined in the valve kit installation instructions. Major modifications or equipment substitution will cause the warranty to be void unless prior engineering approval has been granted by Stanley Hydraulic Tools.
The Stanley priority valve is a metering (to the hydraulic tool) pressure compensating valve that controls the flow to the attachment and gives the primary system (i.e. back- hoe functions) full operating pressure. Diverter valves or simple flow control valves will not perform all of these re- quired functions.
Note:
On carriers where priority valves are not used, check with your local Stanley distributor for an adapter kit to equip your carrier for a specific model of compactor.
LOW-TEMPERATURE WARM-UP PROCE- DURE
When the weather gets cold, the shock mounts on com- pactors can become stiff. In severe weather, where the ambient temperature is below freezing for extended peri- ods, shock mounts can even become brittle. Therefore, it is necessary to warm the shock mounts prior to using the compactor. To warm the shock mounts follow these steps:
1.After starting the carrier, warm up the system until hy- draulic lines are warm to the touch.
2.With the carrier at idle, place the compactor flat on the ground, and using a slight down pressure to keep the com- pactor in place, turn the compactor on. DO NOT place a load on the compactor during this procedure.
3.When the ambient temperature is below freezing, the compactor should be operated on the ground with a slight down pressure (no load) for at least one minute before putting it to work.
