Site Considerations Weight Load Physical Environment Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine. The physical environment where your machine is operated is important for safe operation and the longevity of its components.
Mounting Bolt The base of this machine has holes for mounting it to a workbench. Because of the forces applied to the machine during operation, you MUST firmly mount it to a workbench to prevent it from tipping or shifting during operation. An unexpected movement could result in injury or property damage. Place the base flat on the workbench, slide it back until the stop flanges (see Figure 5) are against the front of the workbench.
Assembly Swing Arm Assembly The Model T23108 is shipped partially assembled. Perform the following procedure to complete the assembly. To assemble the sharpener: 1. Make sure the base is firmly mounted to the workbench. 2. Insert the swing arm pivot stud into the matching hole in the vertical face of the base (see Figure 8). Hex Bolt Figure 9. Swing arm hex bolt inserted. Base Vertical Face Lock Knob Pivot Stud & Hole Figure 8. Swing arm pivot stud and matching hole. 3.
Installing Grinding Wheel 6. Remove the arbor cap screw and outer flange, then place the grinding wheel on the inner flange. 7. Replace the outer flange and arbor cap screw, then tighten the cap screw to approximately 60 inch pounds. To install the grinding wheel: 1. DISCONNECT MACHINE FROM POWER! 2. Select the correct grinding wheel for your chain (refer to Grinding Wheel Selection on Page 20 for detailed information). 3. Perform the Wheel Inspection & Ring Test procedure as instructed on Page 21.
Power Connection Power Connection Test Run Before the machine can be connected to the power source, an electrical circuit and connection device must be prepared per the POWER SUPPLY section in this manual, and all previous setup instructions in this manual must be complete to ensure that the machine has been assembled and installed properly. Once assembly is complete and the sharpener is firmly mounted to a workbench, test run the machine to make sure it runs properly.
SECTION 4: OPERATIONS To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes, lungs, and hands could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and leather gloves when operating this machine. Chain Saw Terminology Refer to the following descriptions and illustrations to better understand the chain saw terminology used in this manual.
Chain Pitch: The distance between any three consecutive rivet centers divided by 2 is known as the chain pitch (see Figure 15). The chain pitch is the same for all links in the chain. The smallest chain pitch for handheld chain saws is 1⁄4", with 3 ⁄ 8" and 0.325" being the most popular. Top Plate Angle: The profile of the cutter link is shaped like a number "7", and is comprised of the top plate and side plate (see Figure 17).
Gullet Angle: The cutter gullet (see Figure 18) provides a space for the wood chips so they can be removed by the top plate. On some chains, it is necessary to have a 10° downward bevel on the bottom of the gullet that forces the chips into the path of the top plate for removal. Depth Gauge: The depth gauge (see Figure 19) is a critical element of the cutter link and is often overlooked in chain saw sharpening.
How the Chain Cuts The depth gauge setting determines how big of a bite the cutter takes ("2–3"). It is imperative that the depth gauge is set below the leading edge of the top plate by the proper amount so that the cutter can move into the wood.
Grinding Wheel Selection Use the chart in Figure 22 as a general guide when selecting the proper grinding wheel for your chain saw. However, we recommend that you always refer to the chain manufacturer's specifications when setting up the sharpener. The grinding wheels supplied with the T23108 are specific to this sharpener. Refer to the specifications below when purchasing replacements. Grinding wheels that break apart during operation can send high-speed debris at the operator or bystanders.
Wheel Inspection & Ring Test 3. At the four spots on the wheel shown in Figure 23, gently tap the wheel with a nonmetallic object, such as a screwdriver handle or wooden mallet. Do not assume that a grinding wheel is in sound condition just because it is new or looks okay. Often damage can occur in shipping, with age, or with exposure to moisture, and may not be visible. Inspect every wheel for damage before installation. First, do a visual inspection.
Top Plate Angle Base Mark It is necessary to have the correct backward top plate angle from the side plate (see Figure 24) to form the cutting point where the top and side plates meet, which initiates the cut. This angle continues the cut and forces wood chips away from the kerf. Lock Knob Top Plate Angle of a Left-Hand Cutter Chain Holder Angle Scale Figure 25. Chain holder angle scale. Note: Always refer to the chain manufacturer's specifications when setting up the sharpener.
Top Plate Cutting Angle The top plate cutting angle (see Figure 26) is a angle on the top plate underside that usually is ground at 60°. The combination of this cutting angle and the top plate angle serves to continue the cut and remove wood chips from the kerf. To set the grinding wheel tilt for the top plate cutting angle: 1. DISCONNECT MACHINE FROM POWER! 2. Loosen the swing arm lock knob (see Figure 27). Angle Scale Top Plate Cutting Angle Lock Knob Figure 27. Swing arm angle scale and lock knob.
Gullet Angle On most chains, the bottom edge of the cutter gullet must have a 10° downward angle from the outside to the inside of the cutter link, as shown in Figure 28. This angle forces wood chips into the path of the top plate for removal. Casting Tilt Marks Base Mark Lock Knob Figure 29. Aligning the chain holder tilt marks. Gullet Angle Outside Tilt Mark Aligned for Right-Hand Cutter Figure 28. Location of the cutter gullet angle. The gullet angle is determined by the tilt of the chain holder.
Sharpening Operation In the following sharpening procedure, you adjust the sharpener settings to grind the correct angles for the chain, then sharpen each cutter link one at a time. After properly sharpening all of the cutter links, you need to check, and if necessary, adjust the depth gauge setting—the distance between the top plate leading edge and the top of the depth gauge.
If the grinding wheel should break apart during operation, the only thing between you and the flying debris of the wheel are the wheel and arbor safety guards. ALWAYS make sure the wheel and arbor safety guards are properly secured in place before connecting the machine to power! 11.
15. Rotate the clamp lever to the right to firmly secure the chain between the clamp plates of the chain holder. 16. Lower the grinding wheel into the cutter gullet until it stops, then thread the depth knob bolt down until it is against the depth stop (see Figure 33). Knob Lock Nut Depth Knob Bolt Depth Stop Figure 33. Depth stop and controls. 20.
Depth Gauge Setting As explained in How the Chain Cuts on Page 19, the depth gauge of the cutter link forces the cutter to pivot forward and self-feed into the wood. The depth gauge setting is the difference in height between the top plate leading edge and the top of the depth gauge. If this setting (see Figure 34) is too high or too low, the cutter will not properly pivot and self-feed into the wood.
SECTION 5: MAINTENANCE Dressing Wheels Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule The edge profile and surface condition of the grinding wheel (see Figure 36) is critical in maintaining the proper shape of the top plate, side plate, and gullet when sharpening.
