This is for your safety and the operating reliability of the machine. General use: • Make yourself familiar with the controls and how to stop quickly. • Read all the instructions in Operator’s Manual and on the machine before starting it. Make sure you understand them, and then follow them. • Only allow adults who are familiar with the machine to use it.
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. 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. If fuel has been spilt on the machine 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 H. This rider mower is equipped with a 15.5 horsepower Briggs & Stratton engine. 6 7 4 5 8 9B 9A 3 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 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 H 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.

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 Check the engine’s oil level Check the oil level in the engine when the machine is horizontal. Dismantle the engine hood as per the description on page 19. 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.
MAINTENANCE Checking and adjustment of the 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 Check the transmission’s oil level 1. Check the transmission’s oil level by removing the transmission cover. Release the two screws (one of each side) and lift off the transmission cover. 2. Unscrew the oil cap and check that the oil level lies between the markings on the dip stick. Top up if necessary with engine oil SAE 10W/30 (class CD-SF) in the same hole as for the dip stick. FULL Check the level of the battery acid Check that the level of the battery acid lies between the markings.
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 16 for correct service interval). 1. Dismantle the engine hood as described on page 19. 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 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. Place a set of bathroom scales under the cutting unit’s frame (front edge) so that it rests on the scales. If necessary a block can be placed between the frame and scales so that the support wheels do not bear any weight. 2.
MAINTENANCE Adjusting the parallelism of the cutting unit 1. Remove the front hood and right-hand fender, as described on page 19. 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. Removing the cutting unit 3 4 1.
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. Remove the cutting unit, see page 26. 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 8. 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. 5. Disengage the spring from the drive belt tensioning wheel. 6. 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. Engage the strut in the holder.
MAINTENANCE 7. Lift off the drive belt (1). Then pull out the pin (2). 1 Take care not to get your hand trapped. 2 8. Pull the frame forwards and insert the pin. 9. Grasp the front edge of the cutting unit, pull out and raise into the service position. Restoring from service position To restore the machine from the service position, reverse the sequence “Placing in Service position“.
MAINTENANCE Lubrication The following two lubrication points should be regularly lubricated with high quality graphite grease. With daily use lubrication should be conducted twice a week. General lubrication All joints and bearings are lubricated on manufacture with molybdenum sulphide grease. Re-grease with same type of grease. Lubricate the steering and control wires with engine oil. The machine should be lubricated regularly, and twice a week when used daily.
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 IMPORTANT INFORMATION On the Bioclip unit the relative positioning of the blades should always be as shown in the diagram with an angle of 90° between the blades. Otherwise the blades can go against each other and damage the unit.
MAINTENANCE Changing the oil The oil should be changed for the first time after 5 hours of running time. Thereafter it should be changed every 25 hours of running time. ! WARNING! Engine oil can be very hot if it is drained off directly after the engine is stopped. Therefore allow the engine to cool down first. 1. Place a receptacle under the engine’s drain plug, located on the left-hand side of the engine. 2. Remove the dip stick and drain plug. 3. Let the oil run out into the receptacle. 4.
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. Release the clamping screw (see arrow) and push the throttle control to full throttle position. 2. Pull the throttle wire’s outer casing to the far right and tighten the clamping screw.
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.
