SAFETY INSTRUCTIONS These instructions are for your safety. Read them carefully. This symbol implies that important safety rules are applicable. 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.
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.
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.

SAFETY INSTRUCTIONS • Avoid overfilling. If 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.

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.
PRESENTATION Cutting unit Jonsered FRM 13 AUTOMATIC is equipped with a Mulcher 90. 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 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. The cutting height of a Mulcher unit is 45-95 mm. Seat The seat has a jointed attachment on the front edge and can be tipped forward.
DRIVING • Read the safety instructions and information on the location and function of the controls before starting (see pages 3-10). • Conduct daily maintenance before starting (see maintenance schedule on page 16). Adjust the seat to the required position. Starting the engine 1.

DRIVING Warm engine: 4. Set the throttle control midway between position 1 and 2. 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.
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. To drive forwards: press down pedal (1). To reverse: press down pedal (2). 3.
DRIVING 4. Push in the lock button on the lift lever and lower down the cutting unit. IMPORTANT INFORMATION The service-life of the drive belts in- creases considerably if the engine is run at low speed when engaging the blades. For this reason do not increase the throt- tle until the cutting unit has been lowered to the cutting position.
DRIVING WARNING! Never drive the machine on ground with a slope of more than 15°. Mow slopes upwards and downwards, never across. Avoid sudden changes in direction. MAX 15 Stopping the engine Preferably allow the engine to idle for a minute to obtain normal working temperature before stopping it if it has been working hard.
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. Daily Maintenance interval mainte- in hours Maintenance Page nance...
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.
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 17. Release the dip stick and pull out. Wipe off the oil and insert again.
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).
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.
MAINTENANCE Replacing the air filter If the engine seems to lack power or goes irregu- larly 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).
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 press- ing too hard against it. The pressure is adjusted with a screw on each side of the machine.
MAINTENANCE Adjusting the parallelism of the cutting unit 1. Remove the front hood and right-hand fender as described on page 18. 2. Unscrew the nut (1) from the parallel strut. Remove the clip (2) and the parallel strut. 3. Turn the fork anti-clockwise to lower the rear edge of the hood, or clockwise to raise the rear edge of the hood.
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 1.

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.

MAINTENANCE 7. Lift off the drive belt (1). Then pull out the pin (2). Take care not to get your hand trapped. 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.
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 manufac- ture with molybdenum sulphide grease. Re-grease with same type of grease.
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.
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.
