: Carefully screw the low speed screw (L) down onto its seat. Then open it one turn counterclockwise. : Start and warm up the engine. : Adjust idle speed with the idle speed screw (LA) so that the cutting tool does not rotate. Fine Tuning A slight correction of the setting of the high speed screw (H) may be necessary if engine power is not satisfactory when operating at high altitude or at sea level or after changing the cutting tool. FS 80, FS 80 R, FS 85, FS 85 R English / USA Rule of thumb Turn high speed screw (H) about 1/4 turn over for every 1000m (3.300 ft) change in altitude. Conditions for adjustment Adjust the high speed screw (H) only if you are using a mowing head, making sure the cutting lines are full length (as far as the limiter blade on the deflector). If you mount a metal cutting tool, use the standard setting. : Carry out standard setting without changing position of high speed screw (H). : Warm up engine for about 5 minutes if you are using a metal cutting tool or about 3 minutes if you are using a mowing head. : Open the throttle wide. At high altitude : Turn high speed screw (H) clockwise (leaner) no further than stop until there is no noticeable increase in engine speed. At sea level : Turn high speed screw (H) counterclockwise (richer) no further than stop until there is no noticeable increase in engine speed. It is possible that maximum engine speed may be reached with the standard setting in each case. Adjusting Idle Speed It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L). : Warm up the engine. Engine stops while idling : Turn idle speed screw (LA) slowly clockwise until the engine runs smoothly – the cutting tool must not rotate. Cutting tool rotates when engine is idling : Turn idle speed screw (LA) slowly counterclockwise until cutting tool stops rotating and then turn the screw about another 1/2 to 1 turn in the same direction. Erratic idling behavior, engine stops even though setting of LA screw is correct, poor acceleration Idle setting too lean: : Turn low speed screw (L) counterclockwise (about 1/4 turn) until the engine runs and accelerates smoothly. Erratic idling behavior Idle setting too rich: : Turn low speed screw (L) clockwise (about 1/4 turn) until the engine runs and accelerates smoothly. FS 80, FS 80 R, FS 85, FS 85 R English / USA Spark Arresting Screen* in Muffler 392BA035 KN If the engine is low on power, check the spark arresting screen in the muffler. : Lift spark arresting screen and pull it out sideways. : Clean spark arresting screen if necessary. : If screen is damaged or coked up, fit a new one. : Refit the spark arresting screen. Checking the Spark Plug 000BA002 KN Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation. If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug. : Remove spark plug – see "Starting / Stopping the Engine". : Clean dirty spark plug. : Check electrode gap (A) and readjust if necessary – see "Specifications". : Use only resistor type spark plugs of the approved range. Rectify problems which have caused fouling of spark plug: : Too much oil in fuel mix. : Dirty air filter. : Unfavorable running conditions, e.g. operating at part load. Fit a new spark plug after approx. 100 operating hours or earlier if the electrodes are badly eroded. * see “Guide to Using this Manual” FS 80, FS 80 R, FS 85, FS 85 R English / USA Lubricating the Gearbox Replacing the Starter Ropeand Rewind Spring 1 1 1 2 3 4 392BA013 KN Removing the Starter Cover 1 233BA010 KN2 : Check grease level regularly - about every 25 hours of operation. : Unscrew the filler plug (1). : If no grease can be seen on the inside of the filler plug, screw the tube (2) of STIHL gear lubricant for brushcutters - see “Special Accessories” - into the filler hole. : Squeeze up to 1/5 oz (5 g) grease into the gear housing. 1 000BA036 TR To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL.

(Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.
