48) to engine crankshaft. See page 10. 3. NOTE: Blade is reversible and can be assembled to crankshaft with either side showing. When sharpening blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds and may cause damage to the unit. Upon reassembly, make certain all parts are assembled properly and tightened securely. LUBRICATION WHEELS—Wheel bearings are of lifetime Forti-flex. They require no lubrication. ENGINE—Follow engine manual for lubrication instructions. A' , CAUTION Do Not deposit material larger than W' diameter in hopper. This may cause damage to the shredding mechanism. Any material heavier than V2” should be fed into the upper guide extension. (See figure 5.) BEFORE STARTING NOTE Do not mix oil with gasoline. 1. Fill fuel tank with fresh regular gasoline. (See figure 6.) 2. Fill crankcase with oil. (See figure 6.) TO START ENGINE 1. Place control lever (on engine) in START position. See figure 7. 2. Move carburetor control to CHOKE position. See figure 7. 3. Rewind starter—use quick full arm stroke. Keep firm grip on handle and return rope slowly. FIGURE 6. Position equipment so that engine is setting level. Remove dip stick or oil filler plug(Figure 6.). Pour oil into oil filler tube from which dip stick was removed and fill to FULL mark on dip stick. Do not overfill. After initial filling follow instructions on dip stick. Be sure dip stick is screwed into filler opening as far as it will go when measuring oil level. During initial break-in period, oil level should be watched closely. See ENGINE MAINTENANCE. Use MS classification oil. Do not use oils marked only MM or ML or unmarked. Above 32° use SAE 30; below 32° use SAE 10W. These recommendations must be followed for best performance and long life. Change oil first two (2) hours of operation and check oil level every five (5) operating hours or each time equipment is used. Change oil every twenty-five (25) operating hours or sooner if equipment is operated in extremely dusty or dirty conditions. NOTE Carburetors are preset at the factory. DO NOT attempt to make adjustments at this time. See carburetor instructions outlined under CARBURETOR ADJUSTMENT. FIGURE 7. TO STOP ENGINE 1. Move control lever to STOP position. See figure 8. 2. Remove high tension wire from spark plug to prevent accidental starting by children while equipment is unattended. FIGURE 8. ENGINE MAINTENANCE To obtain long life and trouble-free service from your engine, certain normal maintenance must be performed as outlined below: 1. Change oil in crankcase after first two (2) hours of operation. Then, follow instructions outlined on page 5. FIGURE 9. /1 \CAUTION Disconnect high tension wire at spark plug to prevent accidental starting of engine. Unscrew oil drain plug located on side at bottom of engine (figure 9). NOTE Always tip engine towards oil drain hole. Be sure oil drains completely. Replace oil drain plug and refill with oil as directed on page 5 or engine nameplate. 2. Check oil every five (5) operating hours or each time equipment is used. If engine has dip stick, keep oil level at mark indicated by adding if necessary. 3. Cleaning engine—This is an aircooled engine which operates most efficiently when the cooling fins are clean. Clean cylinder fins and underside of tank or housing thoroughly of all accumulated grass and debris. 4. Air Cleaner. (See figure 10.) a. Paper Type Element. Remove every 10 hours or oftener if under dusty conditions. Tap to remove loose dirt and/or blow from inside out with low pressure air. Replace if torn or perforated or when plugged to maintain proper carburetor setting (50 hours). DO NOT WASH IN ANY LIQUID AND DO NOT OIL. CARBURETOR ADJUSTMENTS Do not make unnecessary adjustment. Factory settings are correct for most application. If adjustments are needed, proceed as follows: 1. Close power adjusting needle (figure 11) by turning to right (clockwise). Close finger tight only. Forcing will cause damage. 2. Open one turn (counterclockwise). 3. Close idle adjusting needle (figure 11) by turning to right (clockwise). Close finger tight only. Forcing will cause damage. 4. Open one and one-half (1 Vz) turns (counterclockwise). 5. Start engine. Follow starting instructions page 5. 6. With throttle open (carburetor control at RUN or FAST position) adjust power adjusting needle one-eighth (118) turn at a time forward or backward until engine runs smoothly. If engine tends to stall under load enrich mixture slightly (counterclockwise). 7. Hold throttle lever closed or move carburetor control to IDLE or SLOW position and adjust idle adjusting needle until engine runs smoothly proceeding as in step six (6) above. 6 8. Allow several seconds between each adjustment when performing either step ...
