SAFETY WARNING: This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the safety instructions in the manuals and on decals could result in serious injury or death. Slopes are a major factor related to loss-of-control and tip-over accidents. Operation on all slopes requires extra caution. Tragic accidents can occur if the operator is not alert to the presence of children. Never assume that children will remain where you last saw them.
6 2 5 1 4 3 2 OF1625 Figure 2 1. DANGER! TO AVOID SERIOUS INJURY OR DEATH Go up and down slopes, not across. DO NOT operate on slopes over 10°. Read Owner/Operator Manual. OL4450 OL1801 • Keep children and others away from unit while operating. • • • OL4370 Never direct discharge toward other people. Thrown objects can cause injury. Remove objects that could be thrown by the blade. OL0910 • • If machine stops going uphill, stop blade and back down slowly. Avoid sudden turns.
Shut off engine, remove key, read manual before you adjust or repair unit. OL4010 NO STEP! Always keep feet away from rotating parts. OL4420 3. WARNING! Do not operate mower unless guards are in operating position or bagger is attached. Always stand clear of discharge area. OL4430 Do not operate mower unless bagger is attached or guards are in operating position. OL3320 4. HOT SURFACES! DO NOT touch parts which are hot from operation. ALWAYS allow parts to cool. OS0731 5.
DO NOT wear loose clothing or jewelry and tie back hair that may get caught in rotating parts. Wear adequate outer garments. NEVER wear open sandals or canvas shoes during operation. Wear adequate safety gear, protective gloves and footwear. Wear proper footwear to improve footing on slippery surfaces. Always wear safety goggles or safety glasses with side shields when operating mower. Moving parts can cut or amputate fingers or a hand. Wrap blade(s) or wear gloves to service.
Disengage PTO when attachment is not in use. ALWAYS turn off power to attachment when travelling, crossing driveways, etc. Mow up and down slopes, not across them. DO NOT operate on slopes of more than 17 degrees. Use of a Rollover Protection System (ROPS) is recommended for slope operation. See Attachments and Accessories. Always wear a seat belt when operating unit using a Rollover Protection System (ROPS). Keep all movements on the slope slow and gradual. Do not make sudden changes in speed or direction.
ALWAYS wear safety glasses and protective gear near battery. Use insulated tools. DO NOT TIP battery beyond a 45° angle in any direction. ALWAYS keep batteries out of reach of children. Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. ALWAYS block wheels and know all jack stands are strong and secure and will hold weight of unit during maintenance.
