Be extra careful when loading it on a trailer or truck. • Be careful when pulling a load or using heavy equipment. a. Only use approved tow hooks. b. Limit the load to what you can manage safely. c. Do not make sharp turns.
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. • Do not try to stabilise the machine by placing one foot on the ground. • Always keep the rider mower away from edges or ditches when cleaning the chassis.
SAFETY INSTRUCTIONS • Avoid overfilling. f fuel has been spilt on the Rider wipe it up and wait until it has evaporated 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. Rinse immediately with water. If acid gets into the eyes this can cause blindness. Contact a doctor. • Be careful with the maintenance of the battery. Explosive gas is formed in the battery.
PRESENTATION Presentation The power transmission from the engine is handled by a hydrostatic gear box which enables stepless variation of the speed with the foot pedals. Congratulations on your choice of a top quality product which you will enjoy for many years. These instructions describe the Rider 16. This rider mower is equipped with a 15.5 horsepower Briggs & Stratton engine. 6 7 4 5 8 9 There is one pedal for driving forwards and one pedal for reversing.
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. Speed limiter 2 1 The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards and pedal (2) for reversing.
PRESENTATION Cutting unit The Rider 16 can be fitted with four different cutting units. Rear ejector - 970 mm Side ejector - 970 mm BioClip - 900 mm, 1030 mm Lift lever for cutting unit The lift lever is used to set the cutting unit in transport or cutting position. If the lever is pulled back the unit will lift up and the blades will automatically stop rotating (transport position).
PRESENTATION Lever for adjustment of cutting height With this lever the cutting height can be adjusted to 9 different positions (4-90 mm, 45-80 mm Bioclip). Cutting unit with side/rear ejector, 40-90 mm. BioClip cutting unit, 45-95 mm. 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 knobs under the seat and adjust it forwards or backwards to the required position. Lock the setting with the knobs.
DRIVING • Read the safety instructions and information on the location and function of the controls before starting (see pages 7-14). • Conduct daily maintenance before starting (see maintenance schedule on page 20). Adjust the seat to the required position. Starting the engine 1. Lift up the cutting unit by pulling the lever backwards to locked position (transport position). 2. Apply the parking brake. This is done as follows: 2 • Press down the brake pedal (1).
DRIVING Warm engine: 4. Set the throttle control midway between position 1 and 2. 2 1 3 5. Turn the ignition key to start position. STOP START IMPORTANT INFORMATION Do not run the starter for more than about 5 seconds at a time. If the engine does not start, wait about 10 seconds before trying again. 6. When the engine has started release the ignition key to neutral position. Push the throttle control to the required speed. For cutting 3/4 to full throttle.
DRIVING Driving the machine 1. Release the parking brake by pressing down the brake pedal. 2. Carefully press down one of the pedals until the correct speed is reached. 2 1 To drive forwards: press down pedal (1). To reverse: press down pedal (2). 3.

Lift up the cutting unit by pulling the lever back to the end position. 2. Pull back the throttle control and turn the ignition key to the STOP position. STOP START 3.
MAINTENANCE Maintenance schedule The following is a list of the maintenance which should be conducted on the machine. For the items which are not described in these instructions go to an authorised service workshop.
MAINTENANCE Dismantling of the machine hoods Engine hood The engine is accessible for servicing when the engine hood is lifted up. Tilt the seat forward, release the rubber strap under the seat, and tilt the hood backwards. Front hood Release the clip on the front hood and lift off the fender. Right-hand fender Remove the knob (1), the screws (2 and 3) and lift off the hood. 3 11 1 2 Left-hand fender Release the screws in the fender (2) and lift off the fender.
MAINTENANCE RIDE Checking and adjustment of the R 85 0 steering wires The steering is controlled by means of wires. These can in time become slack, which implies that the adjustment of the steering becomes altered. Check and adjust the steering as follows: 1. Dismantle the frame-plate by releasing the screws (two on each side). 2. Check the tension of the steering wires by pushing them together as shown in the diagram.
MAINTENANCE Checking and adjustment of the throttle wire If the engine does not respond as it should do when the throttle lever is moved or if the top speed is not reached, the throttle wire may need adjusting. 1. Loosen the clamping screw (by the arrow), and slide the throttle to the choke position. 2. Pull the throttle wire’s casing as far as possible to the right and check that the choke is fully actuated. 3. Tighten the clamping screw. 4.
MAINTENANCE Replacing the air filter If the engine seems to lack power or goes irregularly the reason may be that the air filter is clogged. It is therefore important to replace the air filter at regular intervals (see maintenance schedule on page 20 for correct service interval). 1. Fold open the engine cover as described on page 21. 2. Remove the air filter housing’s plastic cover by releasing the wing-nut. 3. Remove the wing-nut on the air filter and lift off the paper filter with pre-filter. 4.
MAINTENANCE Checking of the fuel pump’s air filter Check regularly that the fuel pump’s air filter is free from dirt. The filter can when necessary be cleaned with a brush. Check the level of the battery acid Check that the level of the battery acid lies between the markings. Top up the cells with only distilled water. WARNING! Procedures on contact with acid External: Rinse well with plenty of water. Internal: Drink large quantities of water or milk. Contact a doctor as soon as possible.
MAINTENANCE Inspecting the safety system The Rider is equipped with a safety system that prevents starting or driving under the following conditions: The engine should only be possible to start when the cutting unit is in its raised position and the hydrostat pedals are in the neutral position. The driver does not need to be seated in the driver’s seat. Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met.
MAINTENANCE Checking the tyre pressure The tyre pressure should be 60 kPa (0.6 kp/cm2) all round. To improve driving the pressure on the rear tyres can be reduced to 40 kPa (0.4 kp/cm2). The maximum tyre pressure is 100 kPa (1.0 kp/cm2). IMPORTANT INFORMATION Different tyre pressures on the front tyres will result in the blades cutting the grass at different heights. Check the engine’s cooling air intake Fold open the engine cover as described on page 21.
MAINTENANCE Fitting the cutting unit 3 1. Position the Rider on a flat surface and apply the parking brake, see page 12. Check that the lever for adjusting the cutting height is at the lowest setting. Make sure the support wheels are fitted to the cutting unit (1). 2. Grasp the handle at the front (BioClip 90) or hold the frame of the cutting unit (2) and slide the unit underneath the rider mower, making sure that the tongue on the cutting unit (3) engages correctly. 1 2 3.
MAINTENANCE Checking and adjustment of the cutting unit’s ground pressure To achieve the best cutting results the cutting unit should follow the underlying surface without pressing too hard against it. The pressure is adjusted with a screw on each side of the machine. 1. Check the air pressure in the tyres 60 kPa (0.6 kp/cm2). 2. Place the Rider on a flat surface. 3. Put the lifting lever in the mowing position. 4.
MAINTENANCE Adjusting the parallelism of the cutting unit 1. Remove the front hood and right-hand fender, as described on page 21. 2. Undo the nuts on the lift strut. 3. Unscrew the strut (anticlockwise) to lower the rear edge of the hood. Screw the strut in (clockwise) to raise the rear edge of the hood. 4. Tighten the nuts after adjustment. 5. On completion of the adjustment the unit’s parallelism should be re-checked. 6. Fit the right-hand fender and the front hood.
MAINTENANCE Replacing the cutting unit belts Replacing the belts on a BioClip unit A BioClip unit is driven by two toothed belts that synchronise the rotation of the blades. The belts sit underneath a cover on the cutting unit. 1. Dismantling the cutting unit, see page 30. 2. Remove the front pin/bolt from the lift strut and swing the strut backwards. BioClip 103 3. Undo the two screws that hold the safety cover and lift the cover off. BioClip 103 4. Unscrew the nut from the cam and twist the cam off.
MAINTENANCE IMPORTANT IMFORMATION On a BioClip unit the blades are set at an angle of 90° to each other. If this angle changes, the blades may touch and cause damage to the cutting unit. 5. Fitting: First slide on the lower belt, then the upper belt. Check that the blades appear as shown in the diagram, at an angle of 90° to each other. If not, adjust the belts. While the blade bearing is loose the belts can be slid onto the next tooth.
MAINTENANCE Service position for cutting unit The cutting head can be placed in the service position to provide easy access for cleaning, repairs and servicing. In the service position the cutting unit is raised and locked in the vertical position. Placing in service position P 1 1. Position the machine on flat ground. Apply the parking brake (1), see page 12. Adjust the cutting unit to the lowest cutting height and lower the cutting unit. 2. Remove the front hood by removing the pin.
MAINTENANCE 4. Fit the support wheels on either side of the rear of the cutting unit. WARNING! Wear protective glasses when dismantling the cutting unit. The spring which tensions up the belt can go off and cause personal injury. 5. Disengage the spring from the drive belt tensioning wheel. 6. Move the cutting height lever to the lower position. 7. Place a foot on the front edge of the cutting unit near the wheel and raise the front edge of the unit to make it easier to remove the lift strut.
MAINTENANCE 8. Lift off the drive belt (1). Then pull out the pin (2). 1 Take care not to get your hand trapped. 2 9. Pull the frame forwards and refit the pin. 10.Grasp the front edge of the cutting unit, pull out and raise into the service position. If the cylindrical bolt, which is now holding the cutting unit is removed, the cutting unit can be lifted off. Restoring from service position To leave the service position, reverse the procedures set out in “Placing in the service position”.
MAINTENANCE Checking the blades To achieve the best mowing results it is important that the blades are undamaged and well-sharpened. Check that the blades’ attachment screws are tight. IMPORTANT INFORMATION Replacing or sharpening the blades should be conducted by an authorised service workshop. The blades should be balanced after sharpening. Damaged blades should be replaced when hitting obstacles that result in a breakdown.
MAINTENANCE Replacing the break-pin (BioClip) The blades are fitted with a break-pin to protect the BioClip unit and its drive when colliding with obstacles. A domed, spring friction washer is fitted to each blade bolt. The washer must always be replaced with a new washer if the blade bolt is loosened. Otherwise the break-pin can break causing the blades to collide. 5 3 2A Only use original spare parts. A set containing a blade, break-pin and friction washer can be purchased from your dealer. 1.
LUBRICATION Check the engine’s oil level Check the oil level in the engine when the machine is horizontal. Fold open the engine cover as described on page 21. Release the dip stick and pull out. Wipe off the oil and insert again. The dip stick must be fully screwed down. Now release the dip stick again and pull out. Check the oil level. The oil level should lie between the markings on dip stick. If the level approaches the ADD mark, top up with oil to the FULL mark.
LUBRICATION Check the transmission’s oil level 1. Remove the transmission cover. Loosen both screws (one on each side) and lift off the transmission cover. 2. Check that there is oil in the transmission’s oil tank. Fill if necessary with engine oil SAE 10W/ 30 (class SF–CC). Lubricating the belt adjuster The belt adjuster should be lubricated regularly using good quality molybdenum disulphide grease*. 1 nipple from the right-hand side under the engine’s lower belt pulley, until grease is forced out.
TROUBLE SHOOTING SCHEDULE Problem Procedure Engine will not start. • • • • Fuel tank empty. Plug defective. Plug connection defective. Dirt in carburettor or fuel pipe. Starter does not pull round engine. • • • • • • • Battery flat. Bad contact between cable and battery terminal. Lift lever for cutting unit in wrong position. Main fuse blown. The fuse is placed in front of the battery, under the battery cover. Ignition lock faulty. Gear shift/hydrostat pedal not in neutral.
STORAGE Winter storage At the end of the season the machine should immediately be put in order for storage, also if it is going to stand idle for more than 30 days. Fuel which is left to stand for long periods (30 days or more) can leave tacky deposits which can block the carburettor and interfere with the engine. Fuel stabiliser is an acceptable alternative to avoid tacky deposits during storage. If alkylate petrol (Aspen) is used stabiliser is not necessary since this fuel is stable.
