Usage Features:
- Safety Information: The manual prominently features safety information, including "DANGER," "WARNING," and "CAUTION" signs. It stresses the importance of reading and understanding the manual before operation, wearing appropriate clothing, keeping clear of moving parts, and ensuring all safety devices are in place. The maximum transport speed for this implement is 32 km/h (20 mph).
- Pre-Delivery Checklist: A comprehensive checklist for dealers ensures the rake is properly assembled, lubricated, and adjusted before delivery. This includes checking for damaged parts, proper attachment of hoses and fittings, and correct operation of all mechanisms.
- Dealer Delivery Checklist: This checklist ensures the customer receives proper instruction on the rake's operation, safety precautions, raking and windrow width adjustments, lubrication, and the owner's manual. It also confirms the customer signs the warranty registration.
- Set-Up & Assembly: Instructions are provided for assembling the rake and checking tire pressure, lubrication, and tooth bolt torque. It specifies that tooth bolts should be torqued to 40 ft./lbs. and re-torqued after the first 100 acres.
- Transporting:
- Transport Locks: The rake features transport locks on the front of the pole and rake wheel locks to secure the rake wheels in the up position for transport. Hairpins are used to secure these locks.
- Towing on Highway: Users must follow state and local regulations when towing. The maximum speed is 20 mph (32 kph).
- Reflectors: Red and Amber reflective safety decals are provided for safety during transport.
- Preparing for Operation:
- Hitch Adjustment: The tractor hitch should be adjusted to 13 to 17 inches above ground, and the rake's hitch pin should be secured with a safety locking device. The rake frame should be level or parallel to the ground.
- Weight Removal/Addition: Instructions for removing weight from the lift jack and adding weight to the convenient storage mount on the front top of the pole.
- Hydraulic Connections: Connecting hydraulic hoses for raising and lowering rake wheels and for opening and closing the rake.
- Electrical Connection: Connecting a 7-pin electrical connector for optional lighting.
- Operation & Adjustments:
- Emergency Shutdown: Stop the tractor engine, remove the ignition key, and allow all mechanisms to stop before cleaning or working on the machine.
- Raking Width: Raking width is determined by setting the spring-loaded stop located above the rear pole section.
- Ground Pressure: Rake wheel ground pressure is adjusted by turning the threaded rod while the rake wheels are in the raised position. This affects how much pressure is on the threaded rod, which in turn affects ground pressure.
- Windrow Width: Adjusted by turning a crank located on the left rear of the rake.
- Gauge Wheels: Outboard gauge wheels are located on the forward section of each rake beam to follow the contour of the ground. They have an adjustable brake assembly to prevent zig-zag motion when making corners.
- Optional Equipment:
- Optional Center Kicker Wheel: An optional center kicker wheel assembly is available to lay hay in the center of the rake out of the stubble for faster drying and easier pick-up.
- 2-Wheel Center Kicker Wheel: Hydraulically opens the rake to desired raking width. It involves removing and re-inserting locking pins for transport and storage positions.
- Other optional equipment includes Rear Tandem for 4112, Highway Lighting Kit, Wind Panel Kit, Safety Chain, Wrap-Around Front Rake Beams for 4114, and Rake Beam Support Wheels.
Maintenance Features:
- Warranty: H&S Manufacturing Co. provides a warranty for its products. The standard warranty is twelve (12) months on labor and twenty-four (24) months on parts from the date of delivery. Specific components like engines, motors, pumps, etc., are covered by their respective manufacturers. The warranty is non-transferable.
- Warranty Registration: A form is provided for purchasers to register their product, which includes fields for date of purchase, purchaser and dealer information, and product details (model and serial number).
- Cap Screw Torque Values: A detailed table provides suggested torque values for various SAE grades and sizes of cap screws, both dry and lubricated, as well as working torque for brass and silicon bronze fasteners. This is crucial for proper assembly and preventing premature failure.
- Lubrication Guide: The manual includes a lubrication guide with a diagram indicating grease fitting locations and a list of components to be lubricated, such as the top opening arm front pivot, gauge wheel, lift cylinder mounting bracket, rake beam pivot, windrow width adjustment, opening arm rear pivot, kicker wheel pivots, and transport wheel hub. Lubrication should be performed during normal use and before and after storage or power washing.
- Decal Location: Detailed diagrams and a list of part numbers and descriptions for all decals are provided. This ensures that safety and informational decals are correctly placed and replaced if damaged or lost.
- Troubleshooting: A troubleshooting section outlines common problems, possible causes, and possible remedies. For example:
- Rake Will Not Open: Possible causes include rake locked in transport or hydraulic couplers not coupled to tractor properly. Remedies include removing transport locks and returning to storage position, or coupling hydraulic hoses correctly.
- Rake Will Not Close: Possible causes include tractor hydraulics not having sufficient pressure. Remedies include ensuring the tractor has at least 1500 PSI to operate the rake and driving forward slowly while opening the rake.
- Rake Wheels Will Not Lower: Possible causes include rake wheels locked in transport or lift pipe binding. Remedies include removing the hairpin from the adjuster, placing it in the storage position, or checking the lift pipe to ensure it moves freely.
