PRE-START CHECKS STARTING AND OPERATION CAPACITY CRANKCASE OIL STARTING (Electric starting model) e When the temperature is 5°C (41°F) or less Leave the starter switch at “GL” (to preheat) for approximately five seconds, then set it to “ST” (starting). r When combined with a high-starting load machine such as a compressor STARTING (Recoil starting model) This decompression device is automatic return system. After pulling the rope of recoil starter, the decompression lever automatically returns to the original position. And the decompression is released. (Recoil starting model) STARTING AT LOW TEMPERATURE (4) Never open the oil cup lid while the engine is running.

Dust or dirt may be sucked in, possibly damaging the engine. CAUTION 3 3 Never pour any fuel or oil in the oil cup while the engine is running. The engine may overrun, which is very dangerous. FUEL Set the engine to “Compression”. q T a k e y o u r h a n d o f f t h e decompression lever and pull the recoil starter rope gradually. w When you feel heavy in pulling the rope, it is the position of “Compression”. Stop pulling the rope and return the handle slowly to the original position. Set the speed control lever to the “starting” position. Set the speed control lever to the “starting” position.

Pour a small amount of fuel through the oil cup of the air cleaner flange for smooth starting at low temperatures. (1) Take the steps q and w of the recoil starting and make sure the injection sound is proper. (2) Open the oil cup lid and pour a small amount (less than 3 cc) of fuel. (3) Close the oil cup lid. (4) Take the steps e thru t of the recoil starting to start the engine. (Some models have no oil cup.) OPERATION Use the decompression lever for a smoother start. Raise the decompression lever and turn the starter switch to “ST” (starting). Release the decompression lever after the engine rotates smoothly. Some models have no decompression lever. [NOTE] Use SAE No.2-D Diesel Fuel Oil.

As air trapped in the fuel is purged automatically, there is no need to bleed the air. CAUTION 3 3 The engine must be shut down and kept away from any source of fire when fuel is added. Place the engine horizontally and fill it with oil. Always check the oil level with the oil gauge screwed in. On models with an oil filler port in the head cover, be sure to take out the oil gauge first and then pour oil. When filling oil, take care not to let the oil-filling jug’s tip or the like block the oil filler port: this is for air inside the engine to go out of the oil filler port. This is essential for measuring the oil level correctly after letting the poured oil flow down into the oil pan.

Make sure the sound of an injection. q Put up the decompression lever with your left hand and pull the recoil starter rope with your right hand four or five times to turn the crank. w After making sure of the sound of injection, take step e . e If you can not hear the sound, check the fuel level or the position of the speed control lever. Start the engine. q Did you raise the decompression lever? w Grasp the handle of recoil starter properly with your two hands. e Pull the rope fully at a dash and the engine starts. (Pulling the rope at a dash is the knack for easy starting.) r In case engine does not start, repeat item e .

[NOTE] Warm-up As it takes a certain amount of time for oil to circulate through the engine, execute no-load operation for several minutes to check the engine condition. Break-in Break-in the engine for the first week (40 to 50 hours) without applying excess load. (1) If the engine does not start after starter motor is activated for 10 seconds, wait for about 30 seconds and try again, otherwise, damage to starter motor may occur. (2) Never set the starter switch to “ST” during operation to avoid damaging the starter motor. Raise the decompression lever. (Decompress) q M a k e i t c e r t a i n t h a t t h e decompression lever does not go down even after hand is apart from the lever.

w In case the decompression lever goes down, please repeat the operation refferred to in previous item e . (1) Do not put in more than 3 cc of fuel, because otherwise the starting will become difficult. (2) If the engine fails to start at the first try, put in a smaller amount of fuel for the next. (3) It is essential to use SAE10W or SAE10W30 oil for the crankcase in cold season. Higher-viscosity oil makes starting difficult. Setting the starter switch to “ST” (starting) rotates the starter and starts the engine. As soon as the engine starts, release the starter switch. The starter switch position varies by model.

MAINTENANCE (Refer to “PERIODIC SERVICE” when to maintenance.) PRECAUTIONS AT RECOIL STARTING STOPPING THE FUEL FILTER THE CRANKCASE OIL THE AIR CLEANER THE OIL COOLER THE RUBBER HOSE [IMPORTANT] CAUTION 3 3 Always stop the engine before cleaning the oil cooler. Decompression lever “Down” (Released) Decompression lever “Up” (Decompressed) (1) When starting the engine, be sure to raise the decompression lever. (Refer to item STARTING r .) If you try to start the engine without raising the decompression lever, it causes not only difficulty in starting but also sometimes the cause of rope breakdown.

(2) After starting, if you notice unusual sound or smoke from Air Cleaner, stop the engine immediately. Because there is a possibility that engine rotates reversely. (1) Reduce the engine speed and operate it for two or three minutes. (2) Press the stop lever (red) in the direction of the arrow until the engine shuts down. (3) Set the starter switch to “OFF”, then extract it. (Electric starting model) 3 Loosening the idling set bolt enables the speed control lever to shut the engine down. For details, contact your nearest local sales representative. [NOTE] Change the crank case oil 25 hours after initial operation and every 100 hours thereafter, using the following procedure:

(1) While the engine is still warm, empty the crankcase by removing the drain plug. (2) Fill the crankcase up to the specified level with fresh oil. Clean the air cleaner after every 100 hours of operation. If the work site is especially dusty, check and clean the air cleaner every day. Cleaning procedure (1) Remove any dust from the air cleaner and wipe the inner surfaces. (2) Remove dust from the air cleaner element by tapping it gently or by applying compressed air from the inside while rotating the element. If the element is oily or coated with carbon dust, soak it in a neutral detergent solution for 15 minutes, wash it several times, rinse with fresh water, then allow it to dry.

[NOTE] If you pull the rope short, it causes engine not only unstart but also it gives shock to your hand. Pull the rope fully at a dash. (1) Since the fuel filter is made of high- quality filter paper designed to collect fine dust, remove it after every 100 hours of operation by loosening the screw and clean it in fresh fuel. (2) Before removing the fuel filter, always empty the fuel tank by removing the drain plug. [NOTE] (1) Loosen the four bolts and remove the spiral case. Replace the fuel and oil cooler hoses every two years. When leakage is detected during inspection, immediately replace the hose even if its service period has not expired.

3 Never stop the engine using the decompression lever. Otherwise, valves or related parts may be damaged. (1) If the fuel filter breaks, replace it. Otherwise, dust invasion will occur, shortening the service life of the fuel injection pump or nozzle. (2) Note that rough handling of the fuel filter results in damage. STORAGE (1) Replace the engine oil and clean each part. (2) Thoroughly clean the air cleaner element to prevent dust from sticking to it. (3) After the engine cools down, place a cover over it to protect it from dust, then store in a place free from moisture and dust. (2) Check if the cylinder and oil cooler fins are clogged with dust. If so, blow it off using an air gun.
