PRE-START PROCEDURE • ENGINE LUBE: Check level and add oil if necessary of weight and grade specified in Engine Owners Manual. • FUEL SUPPLY: After making sure unit is safely away from ignition producing appliances and in area where gasoline fumes can be dissipated, fill fuel tank with gasoline specified in Engine Manual. • CHECK TIRES and bring pressure up to specifications — 12-15 psi without tire chains or 15-20 psi with chains. • CHECK UNIT to make sure guards and shields are in place and tight. Also check blower housing to insure that it is free of all objects. • RESET RUNNERS to suit area to be cleared. Lower skid shoes to provide greater clearance over gravel or raise the shoes for smooth, paved surface. Refer to skid shoe adjustment • RESET WHEELS for traction if in free-wheeling position (that is, with retaining pins outside the wheel hubs). Pull pins and move into traction position, align holes in hubs with those in drive shaft then reinsert pins. • SET DEFLECTOR CAP to throw snow desired distance. Loosen wing nut, push cap edge back even with the chute to throw snow up to 30 feet away or pull cap all the way out to throw snow only about three feet. Retighten the wing nut after repositioning cap. Always stop engine before repositioning. OPERATIONAL CONTROLS Know how to stop the Snow Thrower quickly in preparation for possible emergency situataions. Forward and reverse motion is stopped by releasing your grip on the TRACTION CLUTCH handle on the left handle bar. The blower auger blades and impeller fan will stop rotating within five seconds* after releasing the BLOWER CLUTCH handle on the right. The engine is stopped by either turning the ENGINE IGNITION key to the left to OFF or by pulling the THROTTLE CONTROL knob rearward to OFF. Other operationalcontrols are discussed where pertinent under the following operating procedures. • NOTE: If rotation continues after five seconds, refer to the BELT AND CLUTCH CABLE readjustment instructions. OPERATION Whenever possible, push Snow Thrower outdoors before starting. If the unit must be started inside your garage, for example, make sure doors are wide open to provide maximum ventilation. Move the unit outdoors as soon as possible after starting. After performing the pre-start checks and services described earlier, proceed as follows: THROTTLE CONTROL: Move control knob into FAST position. CHOKE: Refer to Engine Manual for priming and/or choking details. ENGINE IGNITION: Insert key and turn to ON position. STARTING ENGINE: On Manual Start models, pull recoil start handle in smooth steady motion until engine starts. With Electric Start, plug the three-pronged starter cable into a grounded 110-volt power receptacle and connect the other end to engine start system then turn ignition switch to ON and push button (on engine or in cable) and hold until engine starts. NOTE: Release the button if engine does not start after 30 seconds to prevent overheating of the starting motor. Locate and correct cause of starting problem before cranking again. Detach cable from outlet and from the engine. WARM-UP PERIOD: Allow brief warm-up outside with clutches released to avoid stalling cold engine. Reset Choke as instructed in Engine Manual as the unit warms up. OPERATION: Select desired traction speed by adjusting DIRECTIONAL CONTROL, depress TRACTION CLUTCH handle and drive unit to area to be cleared then depress BLOWER CLUTCH handle and proceed to blow snow. The THROTTLE CONTROL should normally be in the FAST position for best result under most conditions. CAUTION: If clogging occurs, back unit away from snow bank, release both CLUTCH handles and, as a further precaution, stop the engine and remove spark plug wire before clearing the snow from the housing and/or discharge chute. BEFORE STOPPING: Move unit to cleared area, release TRACTION CLUTCH handle and run up to top speed with BLOWER CLUTCH HANDLE depressed to clear housing of slush and snow thus preventing free...
