Practice with the blades "OFF" disengaged, engine speed at a slow setting and in an open area away from obstacles. allow operation personnel. of the machin Section 3 - OPERATING INSTRUCTIONS ROLL RELEASE: To roll the machine without the engine running, pressure within the hydraulic pumps must be released, There is a hydraulic pressure relief valve on the upper side of each pump that is used to release the pressure. Use a wrench to rotate both relief valves counter clockwise two full turns to open, After rolling machine, both relief valves must be rotated clockwise to close valves and tighten securely before operating machine, Machine will not move if relief valves are open, See Figure 3.3. 3.2 STARTING & STOPPING - ENGINE, BLADES, PARKING BRAKE This machine is equipped with dual hydraulic pumps and wheel drive motors. Each pump is controlled by a single motion control lever or joystick. This single control lever (joystick) controls the direction of motion, Forward and Reverse, and the speed of motion. Move the joystick forward to propel the machine forward. Move the control rearward to propel the machine in reverse. The speed of motion is continuously variable from neutral (zero) to maximum. Moving the joystick farther from the neutral position will cause the speed of motion to increase. To turn, move the joystick towards the side you want to turn to. DO NOT make sudden changes in speed or direction. Always slow machine motion before turning. To stop the motion of the machine, bring the joystick back to the neutral position. Engage parking brake. 3.2.1. STARTING ENGINE When the ignition key is turned the engine will not start or turn over unless, the blade switch is pushed in to the "OFF" position, the motion control lever is in the neutral position with the parking brake engaged. 1, Complete pre-start checklist. 2, Sit in operator's seat. 3, Push blade switch in to "OFF", blades disengaged position and engage parking brake.

The unloaded test is the procedure that will be discussed. It's the simplest and most commonly used. An unloaded test is made on a battery without discharging current. To perform unloaded testing, check charge condition using either a hydrometer or voltmeter. 1. Using a voltmeter, voltage readings appear instantly to show the state of charge. Remember to hook the positive lead to the battery's positive terminal, and the negative lead to the negative terminal. AI DO NOT attempt to service or charge the battery I while it is installed in the machine. DO NOT use I "BOOST" chargers on the battery. I 5. Slow charge the battery at 1 amp for 10 hours to bring the battery to fulI charge. 6. After charging, check level of electrolyte and add as needed to bring to proper level 7. Reinstall cell caps. 8. Install battery into power unit. 9. Connect positive (+) cable (red) first, from wiring harness to the positive terminal (+) on battery using bolt and nut provided in hardware bag. Connect negative (-) cable (black) last, to negative terminal (-) on battery using bolt and nut. Apply a small amount of grease over terminals to prevent corrosion. 10. Install battery retainer and positive terminal cover. 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 fulI charge. A reading of 1.230 to 1.260 indicates the battery should be charged before testing. The Battery Condition Chart shows the charge level as measured by syringe float hydrometer, digital voltmeter and five-ball hydrometer. 5.9.5, NEW BATTERY PREPARATION WARNING 1. Remove battery from carton. 2, Place battery in a well ventilated area on a Ievel non-concrete surface. Shield the positive terminal with terminal cover located on battery harness. This prevents metal from touching the positive terminal, which could cause sparks. Cables must be connected to battery terminals in the proper position. RED (Positive) cable must go to the ( + ) terminal. BLACK (Negative) cable must go to the ( - ) terminal. 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, With cell caps removed, connect battery charger to battery terminaIs; RED to positive (+) and BLACK to negative (-) terminal. IMPORTANT: DO NOT place anything in battery other than specified electrolyte. i WARNING DO NOT OVERFILL! 26 PRIMARY MAINTENANCE an illustration of how dirt can dama & how naintenance can protect it!
