IMPORTANT SAFETY PRECAUTIONS

Look for the symbol throughout this manual to point out important safety precautions. Remember, the safety of both yourself and others is involved in the operation of this equipment.

GENERAL WARNINGS
 NEVER operate this or any other equipment under the influence of drugs or alcohol.
 NEVER Operate Without Enclosed Cab.
 NEVER hook up and maintenance cutter without gloves and eye protection.
 NEVER carry passengers on the ROTARY CUTTER.
 NEVER leave the ROTARY CUTTER unattended in a raised position.
 ALWAYS stop and inspect both the skid steer loader and ROTARY CUTTER for damage after striking a foreign object. Any damage should be repaired prior to restarting the skid steer loader engine and resuming cutting.
 Cut only in daylight or well-lit artificial light.
 Keep all nut, bolts and screws tight and be sure the equipment is in safe operating condition and check the blade mounting bolts for proper tightness at frequent intervals.
 If attached to your skid steer loader, visually inspect your lock-on pins to ensure that the ROTARY CUTTER is locked onto your skid steer loader. Remember, the ROTARY CUTTER is made of all steel components and is extremely heavy.
 When working under the deck of the ROTARY CUTTER, always securely block it up to reduce the risk of falling.
 Reduce speeds on slopes and make turns gradually to prevent tipping or loss of control. Exercise extreme caution while making turns on slopes.
 Stay alert for holes or drop-offs on all terrains.
 Use caution when walking on the deck of the ROTARY CUTTER. The deck may be extremely slick when wet.
 NEVER operate your ROTARY CUTTER with the deck raised more than two (2) feet.
 KEEP CHILDREN AWAY FROM THE CUTTING AREA AT ALL TIMES.

DEBRIS DISCHARGE WARNINGS
 NEA METAL COATING, LLC units discharge debris out the front of the machine. When cutting with the ROTARY CUTTER, NEVER discharge material toward bystanders. All bystanders must be AT LEAST 75 feet away when operating the cutter. NEVER allow bystanders near the machine while it is in operation. When cutting near bystanders is unavoidable, DO NOT operate the cutter without the front guard flap in place (if equipped with guard flap).
 ALWAYS clear the cutting area of objects (bottles, rocks, fencing, wire, etc.) that may be picked up and thrown.
 ALWAYS use a shatterproof cab door or the 3/8” thick safety door when cutting. The door is used not only to protect the operator from flying debris, but also from overhanging or protruding objects (tree limbs, rebar, vines, etc.) from entering the cab and causing operator injury.

IMPORTANT SAFETY PRECAUTIONS

ROTATING PARTS WARNINGS
 ALWAYS disengage power to the ROTARY CUTTER and shut the skid steer loader engine off prior to leaving the operator’s cab or performing any inspection or maintenance to either the rotary cutter or the skid steer loader.
 NEVER place hands or feet under the ROTARY CUTTER deck or near the blade system while the unit is in operation.
 NEVER articulate (roll) the deck downward to a degree that exposes the operator to the blade system.

HYDRAULIC SYSTEM WARNINGS
 ALWAYS release the pressure on the hydraulic system of the ROTARY CUTTER prior to removing the attachment from the skid steer loader or working on any part of the hydraulic system. Hydraulic hoses and components operate under extreme pressure and heat. A small stream of fluid from a pinhole leak in a hydraulic hose can penetrate the skin and/or cause burns. Whenever hydraulic fluid is injected into the body, seek medical attention at once to reduce chances of a dangerous infection. ALWAYS wash skin with soap and water after contact with hydraulic fluid, as it is an irritant to skin and eyes.
 NEA METAL COATING, LLC rotary cutters have been designed to reduce the likelihood of hydraulic system leakage. Each and every hydraulic system is checked prior to shipment. However, over time, any hydraulic system may develop fluid leaks. Very small leaks may produce high-pressure discharge flows capable of causing injury should skin come in contact with such discharge.
 Leaking fluid can make the deck and ground surfaces very slippery, causing difficulty in using tools and also increasing the possibility of slips and falls. ALWAYS wipe away all fluid that may have leaked during maintenance.
 NEVER operate a ROTARY CUTTER on a “high-flow” skid steer loader unless the cutter is equipped with a “high-flow” motor. Motor failure can occur if such use is performed. NEA METAL COATING, LLC is NOT RESPONSIBLE for damage incurred to the hydraulic motor due to “high-flow” usage. Please refer to the front cover of the manual for the maximum allowable flow for your ROTARY CUTTER.

OPERATING INSTRUCTIONS

ATTACHMENT OF MACHINE
The installation of your ROTARY CUTTER is the same for any other powered attachment for your skid steer loader:
1. Pull up to the rotary cutter and connect it to your skid steer loader.
2. Secure the lock down lever or levers.
3. Connect the hydraulic hoses from the rotary cutter to your machine. The hoses provided are equipped with quick-disconnect fittings (both male and female) for ease of use.

CUTTING OPERATION
The ROTARY CUTTER is capable of, and in fact intended to be utilized for, mulching trees and other vegetation of varying heights and diameters of up to 3” – 4”. As a safety feature, when cutting large diameter vegetation, the ROTARY CUTTER is equipped with a hydraulic motor cushion valve for shut down of the blade system. This feature lessens the chance of damaging the cutter’s hydraulic system or blade system when cutting larger diameter vegetation. Directions for use are as follows:

CUTTING GROUND LEVEL VEGETATION
Raise the rear of the ROTARY CUTTER approximately 4” – 5” above ground level. The deck of the rotary cutter should be sloping downward and away from the operator. This is the optimum position for cutting materials that are close to the ground. Please note: If the operator can see the blade system in operation, the back of the rotary cutter is raised TOO HIGH!

CUTTING ABOVE GROUND LEVEL VEGETATION
Raise the front deck of the ROTARY CUTTER up approximately 1’ – 2’ above ground level. Do not lift the rear portion of the deck. Keep it approximately 4” – 5” above ground level. Slowly drive into the vegetation and use the hydraulic tilt (roll) the bend or push the vegetation over. As you bend the vegetation over and drive into it, the blades will cut it into. The vegetation can now be mulched by rotating the front of the rotary cutter and driving forward several feet. Then roll the back of the cutter down and back-drag atop the vegetation.

REPAIR AND MAINTENANCE INSTRUCTIONS
PRE-MAINTENANCE & REPAIR STEPS
Prior to performing any repair or maintenance work on your ROTARY CUTTER, make sure that the following steps are ALWAYS followed:
1. Visually verify that the lock-down pins are fully engaged through the quick attach.
2. Release the pressure on the rotary cutter’s hydraulic hoses.
3. Turn the skid steer loader engine off.
4. Disconnect the hydraulic hoses that connect to the skid steer loader.
5. Ensure NUTS & BOLTS ARE TIGHTENED.

BLADE REMOVAL
1. Follow all steps in the “Pre-Maintenance & Repair Steps” at the top of this page.
2. SLOWLY rotate the blade carrier until the blade-attaching nut is aligned in the access hole.
3. From the top of the deck, insert a socket through the access hole onto the blade nut. Remove the nut and insure that the blade drops to the ground. Repeat the process for the remaining blades.
4. After the nuts have been removed and the blades have dropped, back up the skid steer loader and ROTARY CUTTER to retrieve the blades.
5. After retrieving the blades, lower the ROTARY CUTTER back to the ground and shut the skid steer loader engine down.
6. Inspect the blades for damage and determine if the blades need to be sharpened or replaced.
Safety Note: When sharpening or replacing the cutting blades, all blades must be either sharpened or replaced to ensure proper blade balancing. NEVER mix sharpened blades with new blades.
