Product Description
3 Product Description
3.1 Product overview
The Sensomatic Auto Chain Grinder is a machine that sharpens chains. The machine can sharpen chains (up to .404” pitch) for power saws, forestry machines, and harvesters. A pneumatic chain tensioner is attached to the stand. It works with both short and long chains and secures and tensions the chain when it is sharpened. The stand has 2 chain hangers, which makes it easier to separate the sharpened chains from chains that are not yet sharpened.
The machine has 2 grinding modes:
• The regular grinding mode where only the cutters are sharpened.
• The 3in1 grinding mode where all 3 edges (the cutting teeth, the gullet and the depth gauge) on the cutters are sharpened. The edges are sharpened, one after the other, without interaction from the user.
The machine has 2 chain pusher modes:
• The standard mode, used for sharpening of standard chains.
• The skip tooth mode, used for sharpening 3/8” pitch skip sequence chains.
The machine has a sensor system:
• The sensor detects if the next cutter is a right cutter or a left cutter. The grinding head is moved to the correct position to grind the cutter, without interaction from the user. The sensor also detects if there are double tie straps or a broken cutter, and indicates an error.

4.6 Bench-mount the machine
An alternative to having the grinder on a stand is to bench-mount the machine.
Bench-mounting offers you flexibility and the ability to sharpen chains virtually anywhere using the electrical from any wall outlet or use of a 12V power source.
WARNING Put the power converter where there is as little dust as possible and out of reach of sparks from the machine.

4.7 Install and center the grinding wheel
The first step in preparing the grinder for use is installing and centering the appropriate grinding wheel.
The grinder comes with 2 wheel sizes: 3.2 mm (1/8”) and 5 mm (3/16”). These wheels are 150 mm (5 7/8”) in diameter with 16 mm (5/8”) arbor size. It is critical to select the wheel of the appropriate thickness for each chain.
The correct wheel size for a particular Markusson saw chain can be found in several sources: this manual, the back of the Markusson chain packaging, Markusson Maintenance and Safety Manual, or online at Markusson.se
WARNING Inspect the grinding wheel and make sure that it is not cracked or damaged. There is a simple test (called the “ring test”) that you can do to check for damage to a grinding wheel. Hold the grinding wheel up by its center hole. Knock the edge of the grinding wheel gently with a non-metallic object (like the plastic handle of a screwdriver). If the grinding wheel makes a dull, non-metallic noise, then the wheel could be damaged. DO NOT USE IT. CRACKED GRINDING WHEELS MUST BE REPLACED IMMEDIATELY. See also section 6.3, “Change the grinding wheel and fit the grinding wheel guard”.
If the machines are not being used with the stand and the pneumatic tensioner, it should be used with the weight tensioner in order to provide the chain with the tension needed for grinding. The weight tensioner is available separately for purchase (see section 8, “Accessories and Spare Parts”).

1. Turn the grinding speed knob to set the desired speed for the machine.
IMPORTANT If the metal of a cutter turns blue during grinding, the speed is set too high and the metal is overheated. This can cause the metal in the cutter to lose its properties. Replace the damaged cutter or re-sharpen the chain.
2. Fold the grinding head down to its grinding position.
3. The grinding depth for gullets is recommended by the chain manufacturer. To set it, turn the grinding depth knob, located on the back of the grinding head:
• clockwise, to grind shallower into the gullet, or
• counter-clockwise, to grind deeper into the gullet.
5.2.9 Set the cutter top plate to equal lengths
If the right (outer) and left (inner) cutters are not sharpened to equal lengths, follow these steps:
1. Do a sharpening test on a test chain, according to the instructions in section 7.2, “Sharpening test”.
2. Make sure that the right and left cutting teeth are sharpened to equal lengths. Use the template provided with the machine to measure. If they are not equally long, turn the equal cutting teeth knob:
• clockwise to increase the length of the right cutter and decrease the length of the left cutter, or
• counter-clockwise to decrease the length of the right cutter and increase the length of the left cutter.
3. Repeat the sharpening test until the cutter top plates are sharpened to equal lengths. See section 3.2, “Front view”, position (O), and adjust the grinding wheel according to the pictogram under the chain vise.
5.2.10 Center the grinding disc
The diameter of the grinding wheel decreases when it is used. To maintain the grinding proportions, the grinding wheel position must be changed when:
• the grinding wheel has been worn, or
• the chain has a different pitch that requires a different wheel.
1. Use the grinding wheel centering knob to center the grinding wheel over the chain. The gullets should have equal depth on the left and right cutting links.
2. Sharpen a few links and then visually inspect the result. If the grinding depth is not equal on the gullets of the right and left cutting links, continue to the next step.
3. Turn the grinding wheel centering knob to move the grinding motor and the wheel up or down.
4. Set the arrow on the scale to point to the number that corresponds to the wheel diameter, as displayed below. These scale numbers are approximate and are only for general guidance. Observe if the grinding depth of right and left gullets are equal for final adjustment.
