3. Observe the recommended shielding position in transport and working position.
4. The cardan shaft can only be connected or disconnected, when the tractor PTO is disengaged, the engine has stopped and the ignition key has been removed.
5. The cardan shaft must always be properly mounted and protected.
6. When disconnected, secure the PTO shaft to its holder using the provided chain (or other means) to prevent rotation or dragging.
7. Before engaging the tractor PTO make sure that the chosen speed and direction of rotation match the speed and rotation direction specified in the Specifications section.
8. Before engaging the PTO make sure no person is standing in the danger area of the machine. This rule must also be observed during machine operation.
9. Put the disconnected cardan shaft on the intended holder.

Gearbox Oil

⚠️ Must add oil before first use.

THE GEARBOX AND TRANSMISSION ARE SHIPPED WITHOUT OIL. ADD OIL BEFORE FIRST USE!

Gear Oil SAE90 2200ml (approx. 2.3 US Quarts)

Check oil level in gearbox by removing the plug located on the right-hand side. Oil should be level with bottom of plug hole. Add oil if necessary, by removing top fill plug and side plug. Add oil until it flows from side plug hole.

Description of oil plugs:

• Cap for inlet gearbox oil (top fill plug)
• Plug for gearbox oil level (side plug)
• Plug for discharge gearbox oil (bottom plug)

Do not overfill!

IMPORTANT: Implements should be level when checking oil in gearbox!

Required Equipment of the Tractor

• PTO shaft with chosen gear ratio, max. 540 RPM.
• Three-point hitch of I category.

The model MECHMAXX TSG61 requires a tractor of at least 20 hp or up to a maximum of 60 hp.

Maximum number of revolutions and direction of tractor PTO shaft rotation is 540 rpm/min.

PTO Shaft Adjustment

Length of PTO shaft needs to be adjusted for different tractors (figure F1-F4).

Ascertain the accurate length in the following manner:

1. Shut down the tractor.
2. Connect the machine to the tractor.
3. Extract the PTO shaft apart and connect the individual shaft halves to the tractor and machine and compare them crosswise and mark them (figure F1).
4. Shorten external and internal plastic shield tubes (figure F2).
5. Shorten external and internal slide profiles by the same amount as plastic shield tubes (figure F3).
6. Deburr the cut ends of both the inner and outer profiles, remove any filings, and thoroughly grease the sliding surfaces (figure F4).

Diagram Description (F1-F4): These figures illustrate the process of adjusting the PTO shaft length, showing how to mark, shorten tubes and profiles, and grease sliding surfaces.

Tractor Mounting

When connecting the winch, do not stand in the danger zone!

The forestry winch can be attached to every tractor with a three-point hitch with a category I coupling. Appropriate construction also enables easy connection to the tractor with automatic connection rods. Connect the prescribed PTO shaft and secure cardan protection with a hang chain.

Be careful that the cardan clicks into place on both connection points!

Once the winch is attached to the tractor, strengthen the stabilizers on the lower connection rods and level the winch with a hitch nut into position, so that the winch is tilted backwards for approximately 20 degrees.

Grinder Operation

The cutting height should be 0.5"-1.25". Cutting more than 1.25" may make the grinder work slowly.

The grinder should work from right to left or left to right, parallel to the ground, not vertical.

When the attachment has completed a pass, move it rearward about 0.5"-1.25" and engage the control to cut back across in the opposite direction. Never directly up to down.

Operate the cutting wheel at 540 rpm (speed while under no load).

The cutting wheel feed is controlled by the hydraulic cylinder and the pressure control valve.

The rate of cut will depend on the type of tree, condition of the wood, and the condition of the carbide cutting teeth.

Excessive feed rates will either stall the engine or slip the clutch.

Too light a feed will produce sawdust.

Please adjust the two speed flow valves in the cylinders to a suitable level depending on your tractor. Ensure the swing cylinder makes the arm move smoothly and slowly from right to left. NEVER use high speed in cylinder/arm swing moving.

Before Every Use

• Check hydraulic hoses and fittings daily for leaks. Replace hose if worn or damaged. Investigate the location of any oil leaks and repair. Lubricate all joints with lithium grease.
• Inspect the unit for any buildup of contamination (dirt, stones, etc.).
• Check cutting teeth every 2 hours of use. Keep cutting teeth in good condition. Unit will cut faster and remaining teeth will last longer if broken teeth are replaced.
• Check that all fasteners (nuts, bolts, pins, keepers) are in their right place and are tight. Inspect and replace any worn, torn, or missing safety decals.

Every Week

• Check the condition of the teeth base and/or teeth. Order parts if the cutting edge or points are becoming worn and replace as soon as possible.

After Every Season

• Inspect the implement for any loose or worn parts that may need to be replaced prior to the next season.
• Visually inspect the teeth. Replace, if necessary.
• Clean, sand & repaint any area that looks worn or scratched to prevent further rusting. Use an equipment-paint found at your local hardware store or building center.
• Replace any warning decals that have been lost or damaged.
