[. . . ] Operator Manual Please read the operator’s manual carefully and make sure you understand the instructions before using the machine. WH3616 / 966638601 WH4818 / 966638602 WH5218 / 966638603 English In order to implement improvements, specifications and designs can be altered without prior notification. Note that no legal demands can be placed based on the information contained in these instructions. The use of other parts voids the warranty. Do not modify or install non-standard equipment to the unit without consent from the manufacturer. [. . . ] In order, for example, to turn right while moving forward, squeeze the right control upward toward the handle (neutral position). The rotation of the right wheel is reduced and the machine turns to the right. To stop forward travel, pull both drive levers up into the neutral position. When both controls are in the neutral position, the machine stands still. The controls will be locked in neutral position when both neutral locks are engaged. 8062-044 Drive lever - left hand 15 CONTROLS Operator Presence Switches Located on the handle, the Operator Presence System levers serve as an additional safety feature. An electrical interlock safety system is activated by depressing either one or both of the Operator Presence Levers at the handle grips. Releasing both Operators Presence Levers while mowing or transporting will break the electrical circuit and cause the engine and mower to stop. The mower will not stop immediately after releasing the OP levers and some travel occurs. When either the blades or the speed control are engaged, one or both levers must be pressed for the engine to remain running. 8062-044 Operator presence lever - left hand Ground Speed Control Ground speed is adjusted with the center lever on the control panel. Ease the lever out of the start position and upwards to the desired speed. 8062-003 Ground speed control Choke Control The choke control is used for cold starts to provide the engine with a richer fuel mixture. To engage the control, pull the choke out to its extent. Do not use the choke when starting a warm engine. 8062-003 Choke control 16 CONTROLS Throttle Control The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade engagement control is engaged (pulled up). In order to increase or decrease the engine speed, the control is moved forward or backward respectively. Avoid idling the engine for long periods, as there is a risk of the spark plugs fouling. For best mower performance, USE FULL THROTTLE WHEN MOWING. 8062-003 Throttle control Neutral Lock Located on top the motion controls, the neutral locks keep the unit from moving while idling. The locks should be activated when starting the engine. To disengage the locks, squeeze slightly upward on the driver levers and using thumbs, slide the neutral locks back. IMPORTANT INFORMATION Be sure neutral locks are either fully forward (locked) or fully back (unlocked). If the neutral lock is between full forward and full back, the machine will not track properly. 8062-044 Neutral Lock - left hand Tracking Adjustment If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (1 bar). Tracking should be checked on a flat, level surface. Turn the tracking knob (2) clockwise to adjust the mower to the left. Turn the knob counter-clockwise to adjust the mower to the right. 2 1 8062-027 Tracking knob 17 CONTROLS Parking Brake The parking brake is located behind the right hand tire and is applied by pressing the pedal downwards. [. . . ] Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion. 2. Inspect the machine for worn or damaged parts and tighten any nuts or screws that may have become loose. 3. Change the engine oil; dispose of used oil properly. 4. Empty the fuel tanks or add a fuel stabilizer. [. . . ]
