See “Flow Control Valve Plumbing” on page 21 for plumbing requirements. Solenoid Control Option: The Tractor’s hydraulic control lever and PTO shaft will need to be engaged to make control stick functional checks. Independent Control Option: Only the Tractor’s PTO shaft will need to be engaged to make control stick functional checks. 10/11/12 RCP2660, RCPM2660, RCP3060 and RCPM3060 Parallel Arm Rotary Cutter 316-111M 25 26 Section 2: Hydraulic Set-up Options RCP2660, RCPM2660, RCP3060 and RCPM3060 Parallel Arm Rotary Cutter 316-111M 10/11/12 Table of Contents Momentary ON Push Button Checks Cycle “ARM 1”, “ARM 2”, and “Deck Pivot” cylinders to ensure they operate properly as follows: 1. Read and understand hooking-up and unhooking “Transport Safety Chain” on page 17. Remove transport safety chain from the latched position and place loose end on storage hook. 2. Start tractor and adjust 3-Point hitch until PTO driveline is approximately level. 3. Extend and retract hydraulic cylinders as follows: Solenoid Control a. Do not engage PTO for this check. b. Two hoses for operating “ARM 1”, “ARM 2”, and “Deck Pivot” cylinders are connected to a duplex outlet on the tractor. Lock control lever for that duplex outlet in either “Extend Position” or “Retract Position”. c. Refer to Figure 2-14: Press and hold push button labeled “ARM 1 OUT” momentary. The inboard parallel arm should start to extend outward. If it does not move, or moves in the wrong direction (retracts), you should do one of the following: • Change the position of the tractor control lever from automatic retract to automatic extend or vice-versa. • Reverse hoses at the duplex outlet. • Check hydraulic plumbing to and from the solenoid box to make sure hydraulic hoses are not plumbed in reversed order. IMPORTANT: If included, make sure “Deck Float” and/or “Deck Motor” push buttons are “OFF”. d. Check hydraulic fluid level in your tractor's reservoir. If low, add fluid to the system before continuing. The cylinders and hoses will require approximately 1 3/4 gallons from the tractor. Independent Control a. Check Hydraulic Reservoir. Make sure it is full of hydraulic oil and shut-off valve is fully OPEN. b. With tractor engine at an idle, engage PTO and then increase engine speed to about half the cutter rated PTO speed. c. Refer to Figure 2-14: Press and hold push button switch labeled “ARM 1 OUT” (See Arrow) momentary. The inboard parallel arm should start to extend outward. If it does not move or moves in the wrong direction (retracts), you should do one of the following: • Check hydraulic plumbing to and from the solenoid box to make sure hydraulic hoses are not plumbed in reversed order. • Check electrical layout to make sure wiring is correct. 4. After “ARM 1” has been verified to function correctly, purge hydraulic system of air as follows: a. Press and hold push button labeled “DECK DOWN” until deck is in the horizontal position. b. Press and hold push button labeled “ARM 2 OUT” until the outboard parallel arm is fully extend. c. Press and hold push button labeled “ARM 1 OUT” until the inboard parallel arm is fully extend. d. Repeat steps a to c in reverse order to retract all three cylinders. e. Cycle the cylinders to full extension and retraction several times to make sure all air is purged. Parallel Arm Movement Figure 2-14 25849 Table of Contents Section 2: Hydraulic Set-up Options ON/OFF Push Button Checks Refer to Figure 2-15: 2. Check Hydraulic Reservoir shut-off valve. Make sure IMPORTANT: Make sure “Deck Float” and/or “Deck it is fully OPEN before engaging PTO. Motor” push buttons are “OFF”. 1. Read and understand hooking-up and unhooking “Transport Safety Chain” on page 17. Remove transport safety chain from the latched position and place loose end on storage hook. 2. Start tractor and adjust 3-Point hitch until PTO driveline is approximately level. 30020 Make Sure Reservoir Is Full Of Hydraulic Oil Before Engaging PTO Make Sure Shut Off Valve Is Turned ON Before Engaging PTO IMPORTANT: See Figure 2-15: Maker sure reservoir shut-off valve is fully OPEN and reservoir tank is full of oil before engaging PTO. Damage will occur to pump if shut-off valve is “CLOSED.” Float Switch ON/OFF Push Button Check Refer to Figure 2-14 on page 26: Gauge wheels must be installed before checking Float Switch operation. Install gauge wheels per instructions “Gauge Wheels (Optional)” on page 18. Make this functional check with “ARM 1” and “ARM 2” approximately 3/4 extended and with the cutter deck resting on its gauge wheels. 1. Operate “DECK DOWN”, “ARM 2 OUT”, and “ARM 1 OUT” push button switches to lower gauge wheels to ground level. 2. Change Float Switch from “OFF” to “ON”. LED light should be illuminated when Float switch is “ON”. IMPORTANT: With “Deck Float” switch on, DO NOT push “Deck Pivot” and “ARM 2” push buttons for more than two seconds before releasing them. 3. Press and hold “DECK UP” push button for under two seconds. The deck cylinder shoul...
