IMPORTANT: Single Point Depth Control-Make sure tractor flow control is set to fast position. NOTE: For consistent single point performance, always move tractor control lever rapidly from neutral to lower position. 2. SINGLE POINT DEPTH CONTROL- is a convenient method to control working depth and eliminates crawling over or under frame to make adjustments. Use the following procedure when making initial depth control adjustment. For field operation, OPEN transport lock-up valve by turning handle (A) in-line with valve. 3. Place tractor transmission in PARK and/or set brakes and start engine. |
|
CAUTION:
DO NOT adjust machine while in motion. Falling off a moving machine can result in serious injury or death to you or others. ALWAYS stop tractor and lower machine BEFORE adjusting.

Crank (A) moves depth stop which pushes against plunger (B) on control valve to set depth. Use decal (C) as a guide when adjusting single point depth control. On decal, "A" is shallow and "L" is deep. Machine can be set outside of decal's range. Refer to Turn Crank decal (D) and turn crank counterclockwise to raise shanks, clockwise to lower shanks. Five turns equals 25 mm (1 in.) of shank movement.

5.
SINGLE POINT DEPTH CONTROL-
Confirm depth setting. Pull SCV I control switch (A) rearward to raise machine; and then push forward to lower machine and confirm depth setting.
Make a test pass with sweeps in the soil. Stop and check sweep depth. If sweeps are at proper depth, machine is set, if not repeat process until proper depth is achieved.

Before operating machine, make sure air has been bled from wing-fold hydraulic system. Keep all persons away from machine when raising and lowering wings. Always locate machine on level ground when raising and lowering wings. Never raise or lower wings when moving. NOTE: Setup panel can be used to enter time for SCV II to command flow. Detenting rearward and releasing after time-set will cause wing to fold and return tractor to low-pressure standby once time has expired. 6. WINGS ONLY- With machine on level ground and wing area clear of bystanders, push SCV II tractor control lever (A) forward to lower wings (if equipped) and fully extend cylinders.

7.
SINGLE POINT DEPTH CONTROL-
Operate machine over a test distance while pushing depth control lever (A).
8. Stop machine and check depth at sweeps. 9. When desired depth is measured at sweeps, set depth control so it returns machine to this depth. Note depth indicator position for this depth. Depth indicator arrow (B) on machine shows relative depth only and should not be used for depth setting. Depth control must be set by measuring sweep depth. SINGLE POINT DEPTH CONTROL- Place transmission in PARK and/or set brakes and turn tractor off. Set Single Point Depth Control using crank at front of machine. See SETTING SINGLE POINT DEPTH CONTROL.

10.
Operate machine at normal speed and raise and lower machine to confirm depth setting.
SINGLE POINT DEPTH CONTROL- Pull SCV I (A) rearward to raise machine, then forward to lower machine. Confirm depth setting. IMPORTANT: Be sure to rephase depth control cylinders periodically. Rephase cylinders by holding depth control lever for a few seconds after machine has been fully raised. Release control and allow at least three seconds for cylinders to settle past rephasing grooves before lowering machine to operating depth. |
