II. SLOPE OPERATION • Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it. • Mow up and down slopes, not across. • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

SAFETYGLASSES The operation of any tractor can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles. HOW TO USE YOUR TRACTOR NOTE: TO SET PARKING tractor is standing idle with the engine running, hot engine exhaust gases may cause "browning" of grass.
TO ADJUST GAUGE WHEELS TO OPERATE Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions. NOTE: Be sure tractor is on a flat level surface. 1. Lower mower and adjust mower to desired cutting height. 2. Remove retainer spring and clevis pin which secure each gauge wheel bar. 3. Lower gauge wheels to ground.
BEFORE CHECK STARTING ENGINE THE ENGINE 2. Sit on seat in operating position, depress clutch/brake pedal and set parking brake. 3. Place motion control lever in neutral (N) position. 4. Move attachment clutch to disengaged position. 5. Move throttle control to fast position 6. Pull choke control out for a cold engine start attempt. For a warm engine start attempt the choke control may not be needed. NOTE: Before starting, read the warm and cold starting procedures below. 7.
3. Allow one minute for transmission to warm up. This can be done during the engine warm up period. • The attachments can be used during the engine warm-up period after the transmission has been warmed up and may require the choke control be pulled out slightly. NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 F) the carburetor fuel mixture may need to be adjusted for best engine performance (see "TO ADJUST CARBURETOR" in the Service and Adjustments section of this manual).

Overspeeding the engine above the factory high speed setting can be dangerous.
Immediately prepare your tractor for storage at the end of the season or if the tractor will not be used for 30 days or more. _IkWARNING: Never store the tractor with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage.
