[. . . ] replace worn or damaged blades and bolts in sets to preserve balance. On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. Before attempting to start the engine, disengage all blade attachment clutches and shift into neutral. [. . . ] The throttle control regulates the engine revs and thus the rotation speed of the blades. = Full speed = Idling speed When the pedal is pushed down the brake is applied and the motor is disengaged. There are four different positions for this lever: N = Neutral (no drive) S = Slow F = Fast R = Reverse The lever can be moved steplessly between S and F to ensure the required speed. Move the lever forward to connect the drive to the cutting unit, whereby the drive belt is tensioned and the blades begin to rotate. If the lever is moved backwards the drive will be disconnected and the rotation of the blades slowed down by the action of the brake shoes on the pulley. Quick lifting/lowering of the cutting unit Pull the lever backwards to quickly lift the cutting unit when passing over irregularities in the lawn, etc. During transportation the cutting unit shall be in the highest position. There are three different positions for the ignition key: OFF All electric current broken. Never leave the key in the ignition lock when leaving the machine on its own. To release the parking brake all that is necessary is to push down the brake pedal. To tow or move the tractor without the aid of the engine, the free-wheel control knob must be pulled out and locked in position. The wheel is easier to turn if the lever for lifting/lowering of the cutting unit is pulled backwards at the same time. When the engine is cold the choke should be pulled out before starting. When the engine has started and is running smoothly push the choke in. Do not smoke when filling with petrol or fill up when the engine is warm. The combined oil refilling cap and the oil stick is accessible when the bonnet is lifted forwards. SAE 5W-30 oil should be used during the winter (below freezing point). Make sure that the cutting unit is in the transport position (top position) and that the lever for connection/disconnection of the cutting unit is in the disconnection position. If the engine will not start, wait about 10 seconds before the next try. Let the ignition key return to the "ON" position when the engine has started and push in the choke control as soon as the engine is running smoothly. To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor. [. . . ] â· Inspect cooling fan to be sure fan blades are intact and clean. TRANSAXLE PUMP FLUID The transaxle was sealed at the factory and fluid maintenance is not required. Should the transaxle ever leak or require servicing, contact your nearest authorized service center/ department. Unbalance in one or both blades resulting from damage or poor balancing after sharpening. [. . . ]
