Turn the idling end-stop screw "T" to adjust the idling speed in accordance with the details provided in the specification. Use an engine rev counter for this job. • If the idling speed is too high, turn the idling end- stop screw "T" anti-clockwise. • If the idling speed is too low (engine stops) turn the idling end-stop screw "T" clockwise until the engine runs smoothly. If the idling speed cannot be set correctly with the idling end-stop screw "T", request an authorised service centre to tune the carburettor. The following instructions are for authorised service shops Information about the standard settings can be requested from the specialist workshop of our customer service department or downloaded from our Internet portal for specialist dealers at D-CUT carburettors: Use the D-CUT carburettor key to adjust the idle mixture screw "L" and the full load mixture screw "H". Carburettors with limiter caps: The regulating screws for idle mixture and full load mixture can only be adjusted in a limited range. Clean the air filter before adjusting the low speed screw! Let the engine run warm before adjusting the engine speed. The carburettor is tuned for optimum engine performance. Use a rev counter to tune the carburettor correctly! Do not adjust the engine to a higher speed. Excessive engine speed can lead to major engine damage! ENGLISH 9 Maintenance and Care 4.6 Air Filter Maintenance The air filter separates and retains dirt before the air reaches the combustion chamber. This reduces engine wear. Fig. 3b, Type 450 Fig. 3a, Type 444 Regular maintenance increases engine life. Clogged air filters cause performance loss and increased fuel consumption. This leads to a higher toxin level in the exhaust gas and also makes starting more difficult. When the machine is used all day, the air filter should be cleaned daily. In severe dust conditions clean more often in between. For a simple cleaning procedure we recommend tapping the air filter. Never use a high pressure air cleaner nor wet or moist cleaning. Do not use solvent or oil bath cleaners! If engine rpm's tend to drop although the carburettor adjustments are perfectly set, the air filter cartridge is clogged and must be replaced by a new one (Type 444: Order-Nr. 20 48 282) (Type 450: Order-Nr. 20 48 280). Never do realignments on the factory carburettor settings in order to balance a clogged air filter system. This procedure would cause engine damages due overload of the engine. Warranty claims cannot be accepted for damaged engine parts caused by improper care and maintenance For removal of the air filter, remove filter cover. Remove filter cover screw (Fig. 1 Pos. 8). ENGLISH 10 Assembly 5. Assembly Fig. 4 Completely assembly the mistblower before its first use: 5.1 Assembly of misting equipment Attach the blower elbow (1) to the blower housing and secure with both screws (Fig.4D; A+B). Ensure the elbow can swivel easily. Push pleated hose onto blower elbow and secure with clamp (4). 5.2 Assembly of handle, spray tube and spray nozzle Push handle (5) onto spray tube (start from the front) and fix in the required position (Fig.4C). A guide (7) on the spray tube will ensure vertical positioning. Push the spray tube with twist coupling (11) into the pleated hose (5) until locked. Secure with clamp (8). Note: The spray tube can be twisted and turned in the pleated hose with the handle. Ensure that all hose and cable connections are safe and without sharp bends. Place spray nozzle (9) on to spray tube (vertical to handle) and secure (10). Push formula delivery hose (2 pieces) on nipple of the handle and to the spray nozzle. Secure the hose alongside the pleated hose. Shut on/off tap (vertical position), fill some plain water in formula tank and check for any leakage. ENGLISH 11 Starting / Stopping the engine 6. Starting / Stopping the engine Starting with cold engine Fig. 5 •Switch ignition switch to ”I” position and close (OFF) formula on/off tap . •Move throttle lock lever to ”Start” position. Fig. 6a, Type 444 Fig. 6b, Type 450 • Close choke with choke lever. • Press primer several times until fuel is visible in the primer. • Place your left hand on the formula tank of the mistblower. Hold the starter handle (Fig. 1.Pos. 7) with your right hand and pull the handle up slowly until resistance is felt. Then pull up firmly and rapidly until the engine ‘fires’. • Once the engine tries to start, immediately open the choke and continue to start. • When the engine runs, use the throttle lever to accelerate to the required engine speed. For continuous use, set the throttle lock lever (Fig. 1, Pos. 18) in the required position for the desired engine speed. • To return to idling speed, either release the throttle lever or move throttle lock lever down to ”min” position. Starting with warm engine after short stop • Leave choke in ”open” position and start engine. Should the engine refuse to start despite several starting attempts, the combustion c...
