Page 8: Driving On Slopes
SAFETY INSTRUCTIONS • Watch out for traffic when working close to a road, or crossing one. • Be careful when rounding a fixed object so that the blades do not hit it. Never drive intentionally over a foreign object. • The machine is heavy and can cause very severe crush injuries. -
Page 9: Children
SAFETY INSTRUCTIONS • Do not cut close to edges, ditches or banks. The machine can suddenly tip over if a wheel goes over the edge of a drop or a ditch, or if a bank gives way. • Do not cut wet grass. It is slippery and the tyres can loose their grip so that the machine slides. - Page 10 SAFETY INSTRUCTIONS • Avoid overfilling. If fuel has been spilt on the machine wipe it up and wait until it has evapor- ated before starting the engine. If fuel is spilt on clothes, change them. • Be extra careful when handling battery acid. Spilling acid on the skin can cause severe burn injuries.

Page 11: Presentation
Both models are fitted with engines from Briggs & Stratton of 10.5, 12.5 and 15.5 hp. Rider 850 has a cutting unit which throws out the grass at the rear and a cutting width of 850 mm. Location of the controls 1. Ignition lock 2. -
Page 12: Throttle/Choke Lever
PRESENTATION Throttle and Choke lever The engine speed is adjusted with the throttle control, and thereby also the rotation speed of the blades. The control is also used to activate the choke function. When the choke is used the engine receives a richer mixture of fuel and air, which simplifies cold start. -
Page 13: Parking Brake
When engaging reverse gear the lock button on the gear shift must be pressed. Cutting unit Rider 850 has a cutting unit with rear ejection, i.e. the grass cuttings are thrown out behind the cutting unit. Rider 970 can be delivered with a cutting unit which has rear or side ejection. -
Page 14: Lift Lever For Cutting Unit
Lift lever for cutting unit The lift lever is used to set the cutting unit in trans- port or cutting position. If the lever is pulled back the unit will lift up and the blades stop rotating (transport position). If the lock button is pressed and the lever is moved forward the unit will lower down and the blades begin rotating (cutting position). -
Page 15: Seat
Seat The seat has a jointed attachment on the front edge and can be tipped forward. The seat can also be adjusted lengthways. Release the wheels under the seat and adjust it forwards or backwards to the required position. Lock the adjustment with the wheels. Fuelling The engine should be run on at least 92 octane leaded or unleaded petrol/gasoline (not oil mixed). -
Page 16: Driving
Before starting • Read the safety instructions and information on the location and function of the controls before starting (see pages 5–13). • Conduct daily maintenance before starting (see maintenance schedule on page 19). Adjust the seat to the required position. Starting the engine 1. - Page 17 Cold engine: 4. Push the throttle control to position 3 (choke position). In this position the engine receives a richer mixture so that the engine starts more easily. Warm engine: 5. Set the throttle control midway between position 1 and 2. 6.
