3. Verify hydraulics are disengaged.
4. Travel at a reasonable and safe speed.

WARNING
To prevent bodily injury from rotating blade, be sure to disengage hydraulics before transporting tree saw.

Carbide Teeth Break-In
During the first few hours of use, avoid hitting stones as much as possible to allow the carbide teeth to wear slightly. This can be done by keeping the cutting wheel above ground level. Brand new carbide tips are razor sharp and can chip and shatter easily when they hit hard objects. Once the razor sharpness has worn away, the tips do not chip as easily. Observing these precautions will extend the life of the carbide teeth and reduce operating expenses.

The teeth bolts must be retightened every ten minutes for the first hour of use on a new tree saw.

Hydraulic Connections

WARNING
Pressurized fluids can penetrate the skin.

Disconnect and lock out power source before disconnecting and/or connectinghydraulic hoses

The tree saw is equipped with three hoses, pressure, return and case drain. Hydraulic couplers are not provided with the tree saw. Youmust install couplers and connect your skidsteer pressure, return and case drain hoses to the tree saw hoses.

Skidsteer hoses must be the same size as the tree saw hoses. Using smaller diameter hoses will decrease hydraulic flow.

First Time User Tips

• First, operate all functions in a clear area with throttle at low idle to get a good feel for thecontrols before you actually move into any brush.
• Slow cutting speed if pressure surges up closeto max psi, doing this will greatly reduce blade stoppage.
• Run throttle only at half speed for first time users.
• Move the tree saw slowly until you have a better feel how much the unit can take.
• The machine is equipped with a front push bar and an angled push bar to push brush or smalltrees over. This will allow the tree saw teeth to contact the lower portion of the brush and the blade to cut it off.
• For tall brush, you can use the angled push  bar to push the brush over and cut it off close to ground. Each operator must experiment to find a technique that works for them in their application.

WARNING
Always turn off the skidsteer and disengage hydraulic drive before getting off the seat and approaching the blade.

WARNING
Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer.

Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.

Zero Leak Case Drain Relief Valve

The tree saw is equipped with a case drain line thatis to be routed to the excavator hydraulic reservoir.

It is normal for a hydraulic motor to have a slight amount of internal leakage.

The case drain line will allow this internal leakage to be returned to the reservoir, preventing excessive  pressure on the motor seal.Starting with model year 2022, tree saws will be equipped with a zero leak relief valve (A) installed in the case drain line.

If the case drain line is not connected or becomes obstructed, the zero leak relief valve will vent the pressurized hydraulic fluid to the atmosphere. The zero leak relief valve will self reset after hydraulic pressure reduced.

WARNING
Pressurized fluids can penetrate the skin.

Keep bystanders away from machine during operation.

A tiny, almost invisible leak can penetrate the skin, thereby requiring immediate medical attention

If hydraulic fluid is coming out of the zero leak relief valve, shut down machine immediately. Inspect the case drain line connection and lines. Contact your dealer if case drain lines and connection are good.

NOTICE
Environmental hazard. Clean up any spilled hydraulic fluid immediately

A properly installed case drain protected by a zero leak relief valve will save the work of replacing themotor shaft seal and also improve the efficiency of your hydraulic systCem.
