• Do not over-tension the chain as this will lead to excessive wear and will reduce the life of the bar and chain. • Once chain tension is correct, securely tighten bar adjust locking knob. NOTE: The bar adjust locking knob has a detent tightening system. The sprocket cover is secure after three audible clicks are heard. Further tigtening is not required. • When the chain is new, check the tension frequently (after removing battery) during the first 2 hours of use as a new chain stretches slightly. Fig. G 1/8" (3 mm) Replacing the Saw Chain (Fig. A, H) CAUTION: Sharp chain. Always wear protective gloves when handling the chain. The chain is sharp and can cut you when it is not running. WARNING: Sharp moving chain. To prevent accidental operation, ensure that battery is removed from the tool before performing the following operations. Failure to do this could result in serious personal injury. • Flip up locking tab and rotate the bar adjust locking knob 8 counterclockwise to release chain tension. • Remove sprocket cover 6 as described in Installing the Guide Bar and Saw Chain section. • Lift the worn saw chain 5 out of the groove in the guide bar 4 . • Place the new chain in the slot of the guide bar, making sure the saw teeth are facing the correct direction by matching the arrow on the chain with the graphic on the sprocket cover 6 shown in Figure H. • Follow instructions for Installing the Guide Bar and Saw Chain. Fig. H English • DCCS620 requires replacement chain # DWRC1200, service part number 90586162. Replacement 12" bar, service part number N507300. Saw Chain and Guide Bar Oiling (Fig. I) Auto Oiling System This chain saw is equipped with an auto oiling system that keeps the saw chain and guide bar constantly lubricated. The oil level indicator 10 shows the level of the oil in the chain saw. If the oil level is less than a quarter full, remove the battery from the chain saw and refill with the correct type of oil. Always empty oil tank when finished cutting. NOTE: Use a high quality bar and chain oil for proper chain and bar lubrication. As a temporary substitute, a nondetergent SAE30 weight motor oil can be used. The use of a vegetable based bar and chain oil is recommended when pruning trees. Mineral oil is not recommended because it may harm trees. Never use waste oil or very thick oil. These may damage your chainsaw. Filling the Oil Reservoir • Flip down locking lever and unscrew counterclockwise a quarter turn and then remove the oil cap 16 . Fill the reservoir with the recommended bar and chain oil until the oil level has reached the top of the oil level indicator 10 . • Refit the oil cap and tighten clockwise a quarter turn. Flip up locking lever to its locked position. • Periodically switch the chain saw off and check the oil level indicator to ensure the bar and chain are being properly oiled. Fig. L 10 16 Transporting Saw (Fig. A, J) • Always remove the battery from the tool and cover the guide bar 4 with the scabbard 11 (see Figure J) when transporting the saw. • Engage chain brake by pushing chain brake / front hand guard 3 forward.
