Safety of 2,000 psi @ 10 gal/min (138 bar @ 38 L/min). Performance will be reduced if pump output is less. – When fully loaded, the machine can weigh up to 15,432 lb (7,000 kg). Do not go beyond the limitations of the tow vehicle. Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER-"personal safety instruction.
• • • • • – Use extra caution when operating tow vehicle on wet surfaces, at higher speeds or with a full load. Stopping time will increase with a full load. Shift into a lower gear before starting up or down a hill. – Avoid sudden stops and starts. Do not go from reverse to forward or forward to reverse without coming to a complete stop. – Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of control.
Maintenance – Traveling across steep hills with the unit fully loaded could result in tipping over, or a loss of traction for the machine or tow vehicle. • Before servicing or making adjustments to the machine, stop engine of tow vehicle, set parking brake and remove key from engine to prevent accidental starting of the engine. – Always travel straight up and down hills—do not travel sideways or diagonally. When traveling down a hill, do not exceed the speed at which you can travel up the same hill.

Maintenance 3. Wipe up excess grease. The bearing and bushing lubrication points are as follows: Premaintenance Procedures WARNING Disconnect all power sources to the machine before doing maintenance work. WARNING Install the hydraulic cylinder supports before doing any maintenance work under the hopper (Figure 41). Figure 42 Figure 43 Figure 41 1. Hydraulic cylinder support Lubrication The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease.
Conveyor Belt and Rollers • Once a week, check that the conveyor belt is tracking • straight on the rollers and does not slip. Make adjustments if required. Every four months, check that the idler rollers between the front and rear rollers are not bent or seized. Replace or repair if required. Belt and Rear Gate Seals Check all rubber seals for wear or damage. Replace or repair the seals if any leakage occurs.
Material Properties: Viscosity, ASTM D445 Viscosity Index ASTM D2270 Tracking the Conveyor Belt cSt @ 40°C 55 to 62 140 to 152 If the conveyor belt is not centered and tracks to one side, it needs to be adjusted (Figure 46). The best time to do this is between loads during operation. cSt @ 100°C 9.1 to 9.8 1. Go to the rear of the machine and determine which side of the belt is touching.
Tensioning the Conveyor Belt 3. Remove the silicone sealer on the rear of the metal rails (but remember to re apply the silicone sealer when re installing them). Check and adjust the belt tension frequently (Figure 46). All rubber conveyor belts will stretch, especially when they are new or have not been used for awhile. 4. At both front corners, use two wrenches to hold the end of the tensioner rod stationary. 1. Park the MH-400 on level ground with the rear gate and feed gate at least 1/4 inch (6.

Note the position of the cartridge inside the hopper, so that you can re install it in the same position and direction. It is bolted in six places along the side of the machine (three 4 bolt plates on each side). Installing the Belt 22. Secure the cartridge by using straps from a lifting device on each of the four corners.
Adjusting the Conveyor Drive Chain Inspect and service your electric brakes once a year. Adjusting the Electric Brakes If the conveyor drive chain is loose, it needs to be tightened (Figure 50). Adjust the electric brakes after the first three months of operation, or sooner depending on use or performance. 1. Turn off the tow vehicle and set the parking brake. 2. Remove the rear conveyor drive guard. 1. Jack up the machine securely. 3. Loosen the bolt that goes through the tensioner sprocket. 2.
Yearly Brake Cleaning and Inspection Storage Before storing the machine for the season: Inspect and service your electric brakes once a year or more often with heavy use or declining performance 1. Thoroughly clean the machine. Remove parts if necessary. • Change magnets and shoes when they become worn or 2. Remove the wireless controller. Also, remove the batteries from the controller. scored. • Clean the backing plate, magnet arm, magnet, and brake 3. Check all fasteners and tighten, if necessary.
