WARNING Once blades are disengaged, they should come to a complete stop in 7 seconds or less.
SECTION 4 - SERVICE 4.2.3. HYDRAULIC PUMP BELT REMOVAL (Continued) 2. Loosen Nut on Belt Guide at rear of Engine Pulley and remove Cutter Deck Belt from Engine Pulley. 3. Remove Hydraulic Pump Belt. 4.2.4. HYDRAULIC PUMP BELT INSTALLATION 1. STOP ENGINE! Place Hydraulic Belt on Engine and Pump Pulleys. 2. Attach Idler Spring to Bolt and reattach Nut to Bolt. 3. Place Cutter Deck Belt on Engine Pulley. 4.2.5. REPLACEMENT PARTS To retain the quality of your Machine, use genuine SNAPPER replacement parts only.
SECTION 4 - SERVICE 4.4 TRACTION CONTROL ADJUSTMENT 9. Wheel rotation will be stopped by adjusting the eccentric on the pump arms on the right and left pumps. Turning the eccentric slightly clockwise or counter-clockwise will synchronize the pump and traction controls for Neutral. See Figure 3.11. To turn the eccentric, first loosen the bolt in the pump control arm and the nut and bolt fastening the eccentric to the pump control arm. With both Traction Levers latched in Neutral, start engine.
SECTION 5 - MOWER ATTACHMENT SERVICE 5.1 CUTTER DECK BELT REMOVAL & INSTALLATION RIGHT HAND SPINDLE PULLEY 5.1.1. 36” CUTTING DECK BELT REMOVAL 1. Move Mower onto a smooth, level surface. Turn Ignition Key to STOP position, remove Key, disconnect Spark Plug Wire and secure Wire away from Spark Plug. 2. Remove Mower deck belt cover. 3. Remove Idler Tension Spring and swing Idler away from belt. 4. Remove old belt from Spindle Pulleys and Electric Clutch Pulley. See Figure 5.1.
SECTION 5 - MOWER ATTACHMENT SERVICE 4. Refer to the STANDARD BLADE REPLACEMENT chart above for correct SNAPPER replacement Blades. 5. Should Blades be in acceptable condition, sharpen at 22 to 28 degrees. See Figure 5.5. 5.1.5. SPINDLE TO SPINDLE DECK BELT INSTALLATION - 48”, 52”, & 61” CUTTING DECKS 1. Route new belt for 48” cutting deck, 52” cutting deck, and 61” cutting decks, onto bottom groove of center Spindle Pulley and left hand Spindle Pulley. See Figure 5.3. 2.
SECTION 5 - MOWER ATTACHMENT SERVICE 5.3 MOWER SPINDLES (Field Serviceable Spindles) BEARING REPLACEMENT In the event that a spindle bearing requires replacement, the SNAPPER Field Serviceable Spindles have been designed so that no special tools or presses are required. 1. Remove belt. Loosen blade nut and remove. Allow blade bolt, washer, blade and four spacers to drop down out of the spindle housing. See Figure 5.7. IMPORTANT: Spindle housing must be filled with grease before operating mower.
SECTION 6 - BATTERY SERVICE & TESTING 2. A hydrometer measures the specific gravity of each cell. The specific gravity tells the degree of charge; generally, a specific gravity of about 1.265 to 1.280 indicates full charge. A reading of 1.230 to 1.260 indicates the battery should be charged before testing. The chart on the next page shows the charge level as measured by syringe float hydrometer, digital voltmeter and five ball hydrometer.
SECTION 6 - BATTERY SERVICE & TESTING WARNING 6.5 NEW BATTERY PREPARATION DO NOT attempt to service or charge the battery while it is installed in the machine. DO NOT use “BOOST” chargers on the battery. 1. Remove battery from carton. 2. Place battery in a well ventilated area on a level nonconcrete surface. 3. Remove battery cell caps. Fill cells as required with electrolyte (purchased separately) to proper level. Filling battery with electrolyte will bring the battery to 80% charged state. 4.
2 YEAR LIMITED WARRANTY For two (2) years from purchase date for the original purchaser's use, SNAPPER, through any authorized SNAPPER dealer will replace, free of charge (except for taxes where applicable), any part or parts found upon examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.
