Summers Rockpicker - Manual (Page 9)

SECTION 2 - OPERATION AND MAINTENANCE
INITIAL SETUP
HITCH AND SPINDLE SETUP
Install hitch with hydraulic cylinder on left side, attach hitch jack, safety chain, hydraulic hose stand and tip holder. Use
appropriate lifting device, hitch assembly weighs 410 lbs.
16.5L X 16.1 Tire: Attach receiver tube with plate (8R6206) to frame with tube on top. See Page 3-8.
NOTE: Remove safety transport lock pin located under rake AFTER hydraulic lines and cylinders have been filled with
oil.
BEFORE INITIAL OPERATION
1. After receiving your rockpicker, it is a good idea to double check the entire machine so that all bolts
are securely tightened. Recheck after first 2 and 8 hours of operation.
2. Make sure all grease fittings are in place and greased properly.
3. Inflate tires to recommended inflation pressure (see spec. chart on page 2-3) and check wheel bolts
for tightness.
ROAD TOWING
If rockpicker is towed on public roadways, hydraulically swing hitch so rockpicker trails directly behind towing vehicle.
Install Transport Lock (8R7890) to prevent cylinder from retracting. Use transport lock and safety chain when transport-
ing. Check wheel nuts before road transport, after first 20 miles and every 60 miles thereafter. Also, before road transport
check wheel bearings for tightness and that wheel bearings are well greased.

HYDRAULIC REQUIREMENTS FOR MODEL 700 ROTARY ROCKPICKER
1. Closed center hydraulic systems usually work very well.
2. Open center hydraulic systems require sufficient oil flow to operate both the hydraulic reel motor and rake lift cylinders
simultaneously. Because open center systems vary greatly in performance, it is difficult to specify a minimum flow
requirement. For example, some open center systems work perfectly. On others, the reel will slow or even pause
while the rake is being raised. On still other open center systems, the rake can be raised only after stopping the
reel.
Therefore, when purchasing a rockpicker to be used on either a closed or open center hydraulic system, we strongly
recommend the tractor or tractors to be used on the rockpicker be tested for acceptable operation before the machine
is put into field use. It is the responsibility of the dealer and purchaser to make this determination.
If tractor hydraulic pressure and flow are adequate but reel and rake cannot be operated simultaneously, installation
of the Electric Solenoid Lift Option will improve performance. See following page for option installation and operating
instructions.
