DO NOT operate in reverse unless absolutely necessary. ALWAYS backup slowly. ALWAYS look down and behind, before and while backing. DO NOT operate on steep slopes. DO NOT operate on slopes of more than 10°. Operate across the face of slopes, not up and down. Turf conditions can affect the unit’s stability.
To reduce fire hazard and overheating, keep equipment free of grass, leaves, debris or excessive lubricants. Use extra care with grass catchers and other attachments. These can change the stability of the unit. Use only approved hitch points. ALWAYS be aware of attachments when turning. ALWAYS allow adequate clearance between attachments, personnel, and other objects. ASSEMBLY 5. Check engine oil level. See engine manual. WARNING: AVOID INJURY.
OPERATION The blades MUST stop whenever the operator removes both hands from controls while the PTO is engaged. To test: WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. 1. Start engine and engage PTO. 2. Release operator presence control lever(s). Blades must stop. CONTROLS AND FEATURES See Figure 4 for controls and features locations. NOTE: All motion must stop whenever operator releases control levers.
Control Levers (988114, 115, 118, 119, 313) Shift Lever The shift lever sets the direction and speed of the unit. R = reverse WARNING: AVOID INJURY. When the engine is running and the shift lever is engaged, moving only one lever causes the unit to circle around one drive wheel. N = neutral 1 = the slowest forward speed 5 = the fastest forward speed. ALWAYS move levers slowly. The control levers are used to steer, operate in forward and reverse, and stop the unit. Push forward to move forward.
STARTING AND SHUT OFF Recoil Starter Handle Pull the recoil starter handle to start the engine. Before Each Use Hour Meter OG0620 Check each item in Each Use in the Maintenance Schedule.
