See Figure 36. Refer to page 16 for adjustment procedures. Sharpening Instructions (Fig.37) Using a filing gauge Using a depth gauge joiner Using a flat file to round the front corner on a depth gauge Figure 37 IMPORTANT! File all cutters to the same angle and depth! Unequal filing may cause the saw to vibrate or cut erratically! 1. Using a 4.5 mm round file, sharpen all cutters to a 30° angle. Make sure that one fifth (20%) of the file’s diameter is always held above the cutter’s top plate. NOTE: For consistent filing angles, use a filing guide such as Oregon p/n 31692 or equivalent. 2. After all cutters are sharpened, use a depth gauge joiner (Oregon. p/n 106738 or equivalent) to measure the height of each depth gauge. 3. As required, lower the depth gauges to a height of 0.020 inch. Use a flat file; (Oregon p/n 12211 or equivalent). 4. After all depth gauges have been adjusted, use a flat file to round each depth gauge leading edge to its original curvature and angle. MAINTENANCE DESCRIPTION DESCRIPTION Product Description Prior To Assembly Using Figure 4 as a guide, familiarize yourself with the Shindaiwa P231 pole pruner and its various components.

The terms “left”, “left-hand”, and “LH”; “right”, “right-hand”, and “RH”; “front” and “rear” refer to directions as viewed by the operator during normal operation. WARNING! Do not make unauthorized modifications or alterations to your pruner or its components. Long Term Storage Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage: ¦ Clean external parts thoroughly and apply a light coating of oil to all metal surfaces. ¦ Drain all the fuel from the fuel tank. IMPORTANT! All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™ , if oil with fuel stabilizer is not used. To remove the remaining fuel from the fuel lines and carburetor and with the fuel drained from the fuel tank. 1. Prime the primer bulb until no more fuel is passing through. 2. Start and run the engine until stops running. 3. Repeat steps 1 and 2 until the engine will no longer start. CAUTION! Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs. ¦ Remove the spark plug and pour about 1/4 ounce of 2-cycle mixing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug. ¦ Before storing the unit, repair or replace any worn or damaged parts. ¦ Remove the air cleaner element from the carburetor and clean it thoroughly with soap and water. Let dry and reassemble the element. ¦ Store the unit in a clean, dust-free area. MAINTENANCE 135-hour Maintnenace Every 135 hours of operation, remove and clean the muffler. WARNING! Never operate the unit with a damaged or missing muffler or spark arrester! Operating with missing or damaged exhaust components is a fire hazard and could also damage your hearing. 1.

Remove the lower muffler screw, then lift the muffler assembly from the engine. Rear Muffler Shield Figure 35 5. Remove the rear muffler shield bolt and, while noting the orientation of parts, separate the muffler shield. 6. Remove the spark arrester screen and clean with a stiff bristle brush. 7. Gently tap the muffler on a wood surface to dislodge any loose carbon. 8. Inspect the cylinder exhaust port for carbon buildup. IMPORTANT! If you note excessive carbon buildup, consult your servicing dealer. 9. Reassemble the muffler in the reverse order of disassembly. Forward Spark Muffler Assembly Driveshaft/Powerhead 1. Place the powerhead on a clean, flat surface, spark plug facing up. See Figure 5. Tube Clamp Hex Wrench Shim Washer Figure 6 2. Use the 4 mm hex wrench to loosen the tube clamp screw.
