SETTING UP INSTRUCTIONS Note: Determine left and right sides of snow thrower by standing in the normal operating position. INSTALL HANDLES 1. Remove carton from around snow thrower, 2. Remove plastic ties from shandies, controls, and any other area of the unit. 3. Slide handles to the inside of the side plates and line up all holes {(Fig. 1), Figure 1 1. Han die 4. Secure handles to side plates with cap screws and washers (Fig. 2}. Figure 2 1. Handle 2. Cap screw and washer INSTALL THROTTLE CONTROL 1.
SETTING UP INSTRUCTIONS 3. Tighten the jam nut firmly against top of clevis {Fig. 4. Note: Move auger drive control forward to ENGAGE. If excessive force is required to move the control, adjust the auger drive control: refer to Adjusting Montpelier Drive Belt, page 15. INSTALL WHEEL DRIVE CONTROL RODS 1. Move wheel drive control! into No. 1, 1st gear. Position control lever so its front surface inch (6 mm} from bottom of slot {Fig. 5); then hold lever int this position. Figure 5 2.
SETTING UP INSTRUCTIONS 2. The two curved plastic retainers are slotted and are used to secure the discharge chute. Therefore, keep retainers in place (Fig. 8). 3. Move opposite end of retainer under the retaining ring so mounting holes line up and slot in retainer fits over the collar at top of discharge opening (Fig. 8}, 4.
SETTING UP INSTRUCTIONS 2. Push plastic retaining clip holding the wires into hole on top left of main frame {Fig. 12}. Figure 12 1. Engine plug 2 Retaining sip CHECK TIRE PRESSURE IMPORTANT: Check pressure of tires because they are over inflated at the factory for shipping. Therefore, before the snow thrower is operated, reduce pressure in both tires to 10-15 psi. PREPARATION BEFORE STARTING FILL CRANKCASE WITH OIL The engine is shipped from the factory without oil in ghe crankcase.
PREPARATION BEFORE STARTING b Figure 14 1. Dipstick 2. Fitter hot 4. Slowly, pour SAE BE-30 or SAE 10 cil into the filler hole {Fig. 14}, using oil fill chart below. The engine uses any high-duality detergent oil having the American Petroleum Institute — APl — “service classification” Fill Chart e 624 Snow thrower 19 ounces of oil ‘ 824 Snow thrower 24 ounces of OU e Note: Dipstick must be fully installed to assure accurate gauging of oil level. DO NOT OVERFILL.
CONTROLS Auger Drive Control (Fig. 18) — Control has two positions: ENGAGE and DISENGAGE. To engage auger and impeller, push control forward until it stops in an over center position. To disengage auger and impeller, pule control backward, interlock Lever {Fig. 15} — Interlock lever must be compressed against right handle grip when auger drive or wheel drive control is engaged. The engine will shut off if fever is released when auger drive or wheel drive control is engaged.
STARTING AND STOPPING INSTRUCTIONS TO START ENGINE Note: If engine is operated when temperature is +40° higher, remove carburetor heater box. However, the heater box must be reinstalled when temperature falls below +40° remove heater box: A. Remove mounting screws securing heater box in place. Grasp choke knob and pull it off mounting pin. B, Lift heater box up and away from the engine, and reinstall choke knob on mounting pin. 624 Snow thrower Figure 19 1. Mounting screws 2.
OPERATING INSTRUCTIONS FREE WHEELING OR SELF-PROPELLED DRIVE The snow thrower can be free wheeled or engaged for self propelled operation. When axle pins are through outer axle holes {Fig. 16), snow thrower will free wheel. By contrast, when both pins are tantalized through holes in wheel hub and inner hole of axle {Fig. 16}, snow thrower will self propel itself. CHECKING SAFETY INTERLOCK SYSTEM The safety interlock system grounds out and stops the engine through a series of switches {Fig.
MAINTENANCE A CAUTION To prevent accidental starting of the engine while performing maintenance, rotate ignition key to off and remove it from the switch. Next, pull high tension wire off spark plug (Fig. 24) and make sure wire does not accidentally touch the plug, Figure 24 1. High tension wire DRAINING GASOLINE 1. Close fuel shut off valve located under engine (Fig. 25). 2. Place 2 clean drain pan under shut off valve. 3. Loosen hose clamps securing fuel line to naive and slide line off valve, {Fig.
MAINTENANCE 824 Snow thrower Figure 27 2. Drain gasoline from fuel tank: refer to Draining Gasoline, page 12 3. Tip snow thrower forward onto auger housing and block it so it cannot fall. 4. Remove four thread forming screws holding rear shield in place, and slide shield away from traction unit. 5. Lightly lubricate drive chains, sprocket bushing, nylon ring, hex shaft, and the other pivot points with SAE 10W40 (Fig. 28). 6. Wipe up any excess oil and install rear shield with four thread forming screws.
MAINTENANCE Figure 30 1. Pipe plug ADJUSTING SKIDS When snow thrower will be used on concrete or asphalt surfaces, adjust skids using steps 1 3. However, use only step 4 when snow thrower will be used on gravel or crushed rock surfaces. 1. Move snow thrower to a level surface. Next, loosen four flange nuts (Fig, 31} securing both skids to auger side plates. Skids must slide up and down, Figure 31 1. Flange nuts 2. Push snow thrower forward so pivoting scraper blade moves backward. 3.
