SETTING UP INSTRUCTIONS Note: Left and right sides of snow thrower are determined by standing in the normal operating position, INSTALL HANDLE 1. Remove tie straps securing control rods to handier. 2. Position left handle on side of unit, align handier mount holes with holes in side plate and secure with two cap screws and pyramidal washers until finger tight {Fig. 1). Repeat procedure on right side. Make sure handles are at same height {parallel} before tightening handle resews in both sides of unit.
SETTING UP INSTRUCTIONS 2. Align holes in clevis and lower control rod, install with clevis pin {Fig. 5) Figure 5 Jam nut Clevis . Upper control rod L wore control rod Clevis pin . Cotter pin PMS 3. Check the distance between the center of the handle and tip of the auger control lever {Fig.B). Distance should be approximately & inches (12.7 cm}. Figure 6 1. Auger control ravel 2.

PREPARATION BEFORE STARTING FILL CRANKCASE WITH OIL The engine is shipped from the factory without oit in the crankcase. Therefore, before trying to start engine. oil must be added to the crankcase. IMPORTANT: Check elev! of oil every 5 operating hours or each time unit is used. initially, change ofl after the first 2 hours of operation; thereafter, under normal conditions, change oil after every 25 hours of operation.
CONTROLS Auger Drive Control (Fig. 13) — Control has two positions: ENGAGE and DISENGAGE. To engage auger and impeller, compress ever against right handle grip. To disengage, release lever. Traction Control (Fig. 13) — To achieve traction, lever must be compressed against left handle grip.
STARTING AND STOPPING INSTRUCTIONS TO START ENGINE: Nate: (Mo deal 521 only} if engine is operated when temperature is +40° higher, remove carburetor heater box (Fig. 185). However, the heater box must be reinstalled when temperature falls below +40° remove heater box: A. Remove fillips screws and hex head screw securing heater box in place. Pull choke knob off choke rod (Fig. 15) B. Lift heater box up and away from the engine. and reinstall choke knob on mounting pin Figure 15 4. High tension wire 5.
OPERATING INSTRUCTIONS 6. Discharge snow downwind whenever possible, and overlap each swath to assure complete snow removal. if wheels slip, shift into a lower gear which educes forward speed. 7. Normally chains are not required: however, tire chains are recommended when the wheels spin excessively 8. winsome snow and clad weather conditions, some controls and moving parts may freeze solid. Therefore, when any control becomes hard 10 operate. stop the engine: then check all parts for freeze up.
MAINTENANCE CHANGING CRANKCASE OiL Initially, change oil after the first 2 hours of engine operation; thereafter change oil after every 25 hours of engine operation or annually. Hf possible. run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil. Note: Oran oil when fuel tank is empty to prevent spilling gasoline 1. Phil high tension wire off spark plug and make sure wire does not contact plug accidentally 2.
MAINTENANCE Figure 21 1. Se raper 2. Mounting screws Note: Do not use step 3if units to be used on smooth or hard surfaces. 3. Loosen four flange nuts (Fig. 20) securing both skids to auger side plates. Next, skids skids down as far as possible so auger visas far from level surface as skid adjustment allows; then tighten flange nuts. Note: if bottom scraper is excessively worn, replace it ADJ MISTING AUGER CONTROL IF UNIT WILL NOT THROW SNOW 1.
MAINTENANCE 3. Remove auger drive belt from engine pulley and tare auger/impelier pulley {Fig. 23). Figure 24 1. Traction drive bent 2 Auger/impslier drive bet 4. Install new belt around tare auger/ impeller pulley (Fig. 24). Next, loop belt over engine pulley, making sure that belt is on inside of idler pulley and wire belt guide {Fig, 24). 5. Install bat cover with two thread forming S Crews.
MAINTENANCE 2. Adjust upper knockout {Fig. 26} untie there is approximately § between the carter of the handle and the tip of the traction contort lever (Fig. 27} Figure 27 1. Traction control lever 2. Approximately § inches (12.7 con) 3. Test run unit to check adjustment. (Wheels should spin when holding handles}. Repeat adjustment, if necessary, in 1/2 inch {13 mm} increments. ADJUSTING SPEED SELECTOR i there is slow or no ground speed in No. 1 speed selection, or speed selector cannot be moved into No.
MAINTENANCE REPLACING SPARK PLUG Correct spark plug to use is a Champion RJ17LM or Auto lite ARON, and correct air gap is ©.080 of an inch {0.76 mm). Since air gap between center and side electrodes of the spark plug ingresses gradually during normal engine operation. install a new plug after every 25 hours of engine operation. 1. Clean area around spark plug so foreign matter cannot fail into cylinder when plug is removed. 2.
MAINTENANCE 5. Rotate power adjusting screw (Fig. 32} clockwise turn at a time until engine recesses because of a lean gasoline mixture. Then rotate screw counterclockwise — put — 1/8 turn at a time until engine runs unevenly because of a rich gasoline mixture. Next, rotate power adjusting screw clockwise, back to the midpoint between the rich and lean setting so engine runs smoothly. Note: Wait several seconds between each 1/8 turn setting so engine can adjust 10 the new fuel mixture. 6.
